redpotion's Introduction

RedPotion

RedPotion combines RMQ, ProMotion, CDQ, AFMotion, MotionPrint and MORE!. It also adds new features to better integrate RMQ with ProMotion. The goal is simply to choose standard libraries and promote best practices, allowing you to develop iOS apps in record time.

The makers of RMQ and ProMotion at InfiniteRed (web and mobile developers based in Portland, OR and San Francisco, CA) have teamed up with David Larrabee to create the ultimate RubyMotion library.

ProMotion for screens and RMQ for styles, animations, traversing, events, etc.

redpotion's Issues

v1.4.0 Introduction of DataTableScreen breaks TableScreen searchable

Most likely PM::TableScreen is trying to use the PM::DataTableScreen's searchable module instead of the standard ProMotion one :(

Issue discovered by @derekgreenberg.

Test for content in a custom table cell view

I am using a custom cell class in a table cell and passing it state.

Here is my table cell view:

class CustomCell < PM::TableViewCell
  def state=(state)
    build_initial_view unless view_built? # Lay out view unless already laid out
    find(contentView).tap do |c|
      c.find(:label).data(state[:key]) if state[:key] # Pass state to views
    end
  end

  def view_built?
    @view_built
  end

  def build_initial_view
    find(contentView).tap do |c|
      c.append(UILabel, :label)
    end
    @view_built = true
  end
end

In my spec I can then set my view's state by doing something like this:

describe CustomCell do
  def cell
    @cell ||= CustomCell.new
  end

  def default_state
    {  key: "value"  }
  end

  before do
    cell.state = default_state # Setting state
  end

  after do
    @cell = nil
  end
end

What I am trying to do is then test for content like this:

it "has content" do
  cell.find(:label).data.should == "value"
end

When I run my spec I get this error:

  CustomCell has content: FAILED - [].==("value") failed

Any other ways of trying to find the view have failed as well. I either get nil or an empty array as in the above error.

My question is, how can I check that my views have the correct data in my view spec?

Add comments in rakefile

This looks like a pain in the ass to figure out, we should document it with RedPotion comments:

http://community.rubymotion.com/t/how-to-use-enterprise-provisioning-profile/495/3

undefined method `production?' for #<UIApplication:0x10d15b7f0>

According to the docs, there is an app.production? method which is an alias of release?. I added some code to my App Delegate which runs some code that is intended for production/app store release, however I am seeing this error:

2015-06-02 15:49:22.878 app[98811:33490681] app_delegate.rb:7:in `on_load:': undefined method `production?' for #<UIApplication:0x10d15b7f0> (NoMethodError)

    from delegate_module.rb:16:in `application:didFinishLaunchingWithOptions:'
'

Here is my code:

class AppDelegate < PM::Delegate
  status_bar true, animation: :fade

  def on_load(app, options)
    if app.production?
      $API_ROOT = 'https://production.example.com/api'
    elsif app.staging? # TODO: make this work since there is no iOS staging environment
      $API_ROOT = 'https://staging.example.com/api'
    elsif app.development?
      $API_ROOT = 'http://localhost:3000/api
    end
# ...

Am I doing something wrong?

Idea: Swipeable table cells

So I get requests from clients on almost EVERY project that they want to be able to have multiple buttons on either side of a tableview cell to do different things. I'm standardized on using MGSwipeTableCell as the tool of choice because it works well and is easy to understand.

Wondering if anyone else ever sees a need for this and if a DSL would be useful and maybe integrate into redpotion?

Here's a typical cell class:

class ChatCell < MGSwipeTableCell
  def on_load
    delete = MGSwipeButton.buttonWithTitle(
      "Delete",
      backgroundColor: color.grass,
      padding: 20,
      callback: -> sender { delete_action }
    )

    block = MGSwipeButton.buttonWithTitle(
      "Block User",
      backgroundColor: color.red,
      padding: 20,
      callback: -> sender { block_action }
    )

    self.rightButtons = [delete, block]
    self.rightSwipeSettings.transition = MGSwipeTransitionDrag
    self.rightExpansion.buttonIndex = 0
    self.rightExpansion.fillOnTrigger = true
  end

  def will_display
  end

  def delete_action
    mp "deleted!"
  end

  def block_action
    mp "blocked!"
  end
end

I'm thinking that this could be shortened to something like we do in ProMotion for the left and right titlebar buttons:

class ChatCell < PM::SwipeTableCell
  def on_load
    set_right_buttons([{
      title: "Delete",
      background_color: color.grass,
      padding: 20,
      action: :delete_action,
    }, {
      title: "Block User",
      background_color: color.red,
      padding: 20,
      action: :block_action,
    }], {
     # Options
     transition: MGSwipeTransitionDrag,
     expansion_index: 0,
     fill_on_trigger: true
    })
  end

  # ...
end

Screen vs. Controller in Stylesheet Naming

Moving projects over to redpotion, BlahController needs to be renamed to BlahScreen. But then there's the additional headache of BlahControllerStylesheet needing to be renamed to BlahScreenStylesheet. Plus... sometimes you don't have everything moved over.

Thoughts on the Stylesheet name being shortened and agnostic? BlahStylesheet?

Stylesheet drops WeakRef

When returning to a view controller (for example - after having logged in using Facebook SDK or similar), the WeakRef the stylesheet holds for the controller is dropped, resulting in a:
old_home_screen_stylesheet.rb:1:in stylesheet': Invalid Reference - probably recycled (WeakRef::RefError)`

when trying to apply any style after returning.

Building vendor project `vendor/Pods' failed to create at least one `.a' library

Hiya!

I'm trying to get started with redpotion, but can't get past the initial setup. I'm on Yosemite, xcode 6.3 and everything else is set up fine (rake'ing a normal ruby-motion project works fine) but as soon as I've created the redpotion project (by the way, the documentation still has 'redpotion create ' instead of the rails-like 'redpotion new ') and I try to rake it, it fails creating .a libraries (or finding them?) for the vendor/Pods

I've tried to rake clean and rake newclear hoping it'd be that easy, but with no luck. Opening the .xcodeproj for Pods in Xcode and building it works fine as well. I thought, at first, that it might be that I'm on a case-sensitive HFS partition which has caused me trouble before (coming from Linux, when I installed I thought 'why wouldnt it be case sensitive?' and thats where that mistake is from) but the issue remains the same even after doing it all in a case sensitive sparsebundle.

Here's my stacktrace:

Any idea of what may be causing this? I've also tried downgrading the cocoapods gem, building in Xcode first, and so on - no luck.

What to set for codesign_certificate?

Sorry, I'm new to building RubyMotion apps. I see in the generated Rakefile that RedPotion sets some sample values for codesign_certificate and provisioning_profile:

  app.release do
    app.entitlements['get-task-allow'] = false
    app.codesign_certificate = 'iPhone Distribution: YOURNAME'
    app.provisioning_profile = "signing/myapp.mobileprovision"
    app.entitlements['beta-reports-active'] = true # For TestFlight

    app.seed_id = "YOUR_SEED_ID"
    app.entitlements['application-identifier'] = app.seed_id + '.' + app.identifier
    app.entitlements['keychain-access-groups'] = [ app.seed_id + '.' + app.identifier ]
  end

I didn't find any documentation on this in the RedPotion docs but it would be really helpful for newcomers like me. I managed to work my way through the Apple Dev Center and iTunes Connect to generate a .certSigningRequest, .cer, and .mobileprovision files. Now I'm trying to build and push to iTunes Connect for Test Flight distribution.

It looks like RedPotion is looking for my provisioning profile in a signing directory which was not generated, so I created one and moved the file there. Seems like maybe this directory should be automatically created and added to the .gitignore file, but maybe there's a reason that it is not. So now what do I set for codesign_certificate? Am I supposed to put my name/email in the YOURNAME placeholder? Or am I supposed to point to the .cer file?

Also I'm not sure what the seed_id option is for. I might run into that issue next. Some comments in the Rakefile would be helpful, or a page on the documentation site (which has been super helpful by the way!).

Any help you can provide would be greatly appreciated. Thanks!

Live reloading doesn't work for modules included in stylesheets

In the example below, when live is invoked in the REPL, updates to style1 are applied, but not when you update style2.

class MyStylesheet < ApplicationStylesheet
  include MyStylesheetAdditions

  def style1(st)
    # whatever
  end
end

module MyStylesheetAdditions
  def style2(st)
    # whatever
  end
end

UINavigationBar appearance not being applied

Hi there, first of all, really great work!

Issue

I'm having issues updating the UINavigationBar appearance from StandardAppearance. Uncommenting this block:

UINavigationBar.appearance.tap do |o|
  o.barTintColor = rmq.color.black
  o.setTintColor rmq.color.black

  o.setTitleTextAttributes( {
    UITextAttributeFont => rmq.font.medium,
    UITextAttributeTextColor => rmq.color.white
    #UITextAttributeTextShadowColor => color.clear
  })
end

Yields no change to the styles.

Env

iOS Simulator - iPhone 6 / iOS 8.4
redpotion (1.4.0)
Rubymotion 4.0 AND 3.14

Please let me know if you need any other info and any advice would be greatly appreciated!

Idea: React-style state model view rendering

Per my article posted this morning, I'd like to discuss bringing in a React-style set_state method on PM::Screen and providing a render (or layout) method in the RMQ stylesheet.

Other things to discuss:

View hierarchy diffing -- is it worthwhile from a performance standpoint? Updating UI elements in RMQ is super fast, so it might not make sense.
Components -- should we have some analog to React.js components?
Table screens / collection screens -- this should be easy(ish) with update_table_data and the like, but we should discuss.
Animations -- animating between state changes

Lastly, I have to thanks @twerth for building RMQ -- makes this sort of thing so easy. :-)

Generic screen template

@jamonholmgren and I talked about some new templates in RedPotion, one is a generic screen:

Basically we need a way to make any ol' controller a screen. API would be like this:

potion create generic_screen UICollectionViewController foos

That would create that controller as a screen and include the include ProMotion::ScreenModule as well as some other included commented out. This way you can turn any controller type into a screen.

It should name this a screen and place it in the screens folder.

potion create model foo hangs

This is majorly harmless bug but I thought I'd report it anyway just so it's known.

For some reason the potion create model model_name hangs when I try it. If I go for rmq create model model_name instead, it works without issue.

I'm have redpotion v 0.7.1, rmq 1.1.0, promotion 2.2.1(only redpotion is in the gemfile though)

It seems to hang forever before anything is outputted to the terminal until I control+c

In specs, in the template, should turn off animations by default?

In specs, in the template, should turn off animations by default? Having animations on in specs causes all sorts of issues.

UIView.setAnimationsEnabled false

"potion create model foo" hangs

potion create model foo just sits there, waiting for something, the train perhaps.

Failing tests removed - needs TLC

I'm going to comment these tests out in my local branch to avoid false positives with my PR, but I'm documenting them here.

@markrickert here's the info

data_table_screen_spec.rb has 1 failing test and 2 errors on lines:

What's the recommended approach for catching a touch event on a cell in a DataTableScreen?

I've got a simple ::PM::DataTableScreen that looks like this:

class TagsPopularScreen < ::PM::DataTableScreen
  title 'Popular'
  stylesheet TagsPopularScreenStylesheet
  model Tag, scope: :where_is_popular
  searchable placeholder: "Search", fields: [:tag], hide_initially: true
end

What's the recommended approach for catching a touch event on one of the cells? This is trivial in a normal ProMotion table screen because you're providing the actions with the cell data. But I'm not sure what the right way to do that would be for a table where the data is coming from a CDQ data source.

Do I need to get in underneath and catch the raw iOS touch event for the table and work out manually what cell was tapped? Or is there a shorthand?

Thanks,
M@

PM::TableScreen cell editing_style: :delete not work

TableScreen: swipe to delete not work. in RedPotion, ProMotion version is 2.3.1 also not work.
ProMotion 2.4.1 work well but 2.4.0 also not work.

Thanks.

First "big" feature: ProMotion tables + core data

... and I have no idea how to implement it, but it would be wonderfully nice if one could have an easy way to tie in core data into a ProMotion TableScreen.

Having trouble changing color of title in nav bar in tab bar screen

I have been able to change the color of the title within a regular screen. However, now I am using a tab bar and it is not applying the color to the title.

class ListScreenStylesheet < ApplicationStylesheet
  def nav_bar
    controller.navigationController.navigationBar
  end

  def setup
    nav_bar.translucent = false
    nav_bar.barTintColor = color.dark_gray
    nav_bar.tintColor = color.white
  end
end

It is correctly changing the background color, but not changing the text of the title to white. However, it is changing the color of the right/left nav bar items to white text. From what I understand, tintColor controls the color of the title too. Am I doing something wrong?

Cell height

Hi, following example code:

module MyCellStylesheet
  def my_cell_height
    300
  end

  def my_cell(st)
    st.frame = { l: 5, t: 100, w: screen_width, h: my_cell_height }
  end
end

No matter what I enter as my_cell_height (e.g. 300 or 10), the actual height of the cell doesn't change. I've tried with different cells and different heights but nothing happens. As the redpotion generator generates the code regarding the height, I assume this is the correct (and only) place to change the height.

This is what the log tells me:

Require the cell template included in the model - DataTableScreen

Per a discussion we had on #64, I would like to propose that we enforce that the model is where the cell structure is defined. It's cleaner, and more intention leading.

@markrickert and I both agree that we prefer forcing the dev specify the cell be in the model. We should probably include that the cell method is implemented on the model and raise an error if not if we are going to be forcing that the cell is defined in the model used for the screen.

I am interested in others thoughts, agree? disagree? Dont care? Chime in now!

Automatic resizing for smaller devices

Hi again guys.

I am having a problem making my app layout look good on some screens I made by hand on smaller devices. The app is designed for iPhone 6 and I am testing on iPod Touch 5g. Is there a recommended way of doing this? I'm not sure how to set up RMQ so that the views auto resize but it looked like this was supposed to happen by default. I would provide screen shots but they kind of give our app away. The basic problem is that stuff is too big and it is leaking off the edge. Do I have to detect each screen size and provide sizes for each? That seems... tedious.

Anyway thanks again for a great library and I hope I'm not taking up too much of your guys time. Lol

Add on_load to UIView

The next version of ProMotion will work with .on_load on a view, this will get called if ProMotion creates a view, such as in a table. IMO RedPotion should also call on_load anytime it currently calls rmq_build. And we should prefer on_load over rmq_build for RedPotion projects.

Frame isn't properly calculated

When appending views inside other views:

class SignupStartView < UIView
    attr_reader :sign_up, :sign_in
    def initWithFrame(rect)
        if super
            append!(UIImageView, :logo)
        end
        self
    end
    def drawRect(rect)
        super
    end
end

and then setting the frame of UIImageView with:

  def logo(st)
    st.image = UIImage.imageNamed('signup/logo_title.png')
        st.frame = {l: 5, t: 5, fr: 5, fb: 5}
  end

frame isn't properly calculated. Even though the SignupStartView receives a frame of

<CGRect origin=#<CGPoint x=0.0 y=0.0> size=#<CGSize width=375.0 height=274.0>>

the frame of the UIImageView is set to:

<CGRect origin=#<CGPoint x=-5.0 y=-5.0> size=#<CGSize width=10.0 height=10.0>>

When setting widht/height manually in the stylesheet, it works as expected?

Loosen RMQ and ProMotion dependencies

Interested in others thoughts on if there is a reason we should not do this?

I think that we should change our dependencies on RMQ and ProMotion to be less restrictive and only bump the requirement when we know there is new functionality in the dependent gem that we require.

Currently we have:

spec.add_runtime_dependency "ruby_motion_query", "~> 1.4.0"
spec.add_runtime_dependency "ProMotion", "~> 2.3.1"

but is there any reason we should not do:

spec.add_runtime_dependency "ruby_motion_query", ">= 1.4.0"
spec.add_runtime_dependency "ProMotion", ">= 2.3.1"

I have thought about this a few times, but if I read #106 correctly, I think the problem is there was a bug fixed in 1.4.1 of ProMotion - but as a user of RedPotion you are restricted to our next release - if we loosened the restriction like above - I as a user could bump ProMotion without any new redpotion release, and fix the underlying bug that was fixed in that product.

title_view in PM::TableScreen doesn't work

Hi!

I am trying to style a PM::TableScreen according to my client design specs.

The title_view command isn't working, I generated a new view using potion create view.

LineListScreen.rb

class LineListScreen < PM::TableScreen
  title_view Title.new
  refreshable
  searchable placeholder: "Search"
  stylesheet LineListScreenStylesheet
  include API

  def on_load
    @table_data = []
    load_async
  end

  def load_async
    get_lines do
      @lines = Line.all.to_a
      @table_data = [{
        cells: @lines.map do |line|
          {
            title: line.name,
            subtitle: "phone number"
          }
        end
      }]
      stop_refreshing
      update_table_data
    end
  end

  def on_refresh
    load_async
  end

  def table_data
    @table_data
  end

end

Title.rb

class Title < UIView

  def on_load
    apply_style :title

    append UILabel, :virtualq
  end

end

LineListScreenStylesheet.rb

class LineListScreenStylesheet < ApplicationStylesheet

  include TitleStylesheet

  def setup

  end

  def root_view(st)
    # st.superview.superview.frame = {l: 0, t: 0, w: 375, h: 648}
    # st.superview.superview.background_color = color.virtualq
    st.background_color = color.vq_gray
    # mp st
  end
end

TitleStylesheet.rb

module TitleStylesheet

  def title(st)
    st.frame = {l: 0, t: 0, w: 375, h: 64}
    st.background_color = color.virtualq
    # Style overall view here
    mp st 
  end

  def virtualq(st)
    st.frame = {l: 0, t: 0, w: 375, h: 64}
    st.text_alignment = :center
    st.text = "virtualQ"
    st.background_color = color.virtualq
    st.font = font.medium_small
    mp st
  end

end

As far as I can tell, Title.rb's on_load never gets called. The TitleStylesheet also never gets called.

Am I doing it wrong?

Undefined method make_button

Hi, In a PM::TableScreen I'm trying to use the app.make_button method to create some buttons for an ActionSheet. Unfortunately I get an undefined method error.

I copied the button code from an example of the docs, my code looks basically like this (the error happens using this code):

class HomeTableScreen < PM::TableScreen
  title "Test"
  stylesheet HomeTableScreenStylesheet

  def on_load
    some_action
  end

  def table_data
    [{ cells: some_data }]
  end

  def some_action
    taco = app.make_button("Taco") {
            puts "Taco pressed"
          }
  end
end

Here is the stack trace (I can provide the generated crashlog if needed):

"potion create my_new_app --skip-cdq" should remove cdq.yml and schemas folder

While testing potion create my_new_app --skip-cdq I noticed these still exist:

/resources/cdq.yml
/schemas

Remove exception when stylesheet is not defined

@twerth had mentioned removing the exception for when a stylesheet is not defined. Let's remove that as RedPotion, RMQ, and ProMotion will continue to work without it, it simply wont have a nice place to put all the styles.

Should we warn, or just let it be when one is not provided?

when using ProMotion-form on_load and similar methods are called twice

I've set up a demo repo here.

https://github.com/markrickert/redpotion_bug_91

Go ahead. try it.

then comment out redpotion and bundle, run again and you'll see on_load and will_appear are only called once.

`potion create` is generating a Rails app?

Okay, this is bizarre. I just installed and generated a new RedPotion app and it generated what looks like a Rails app instead of a RubyMotion app:

Be nice to have repo based documentation, but not in the ReadMe. In markdown. Something people can do a PR for. Perhaps a script to push it to wherever it lives. Like ProMotion does.

Idea: DataTableScreen refreshes row automatically when the model file is saved to core data

So I think this might be a really killer feature to have:

I have my managed object:

class Whatever < CDQManagedObject
end

and a PM::DataTableScreen that displays its contents.

Core data ManagedObjects give us a didSave method that's called when core data saves the file to the store. I've verified that it's called when you do a cdq.save.

Now we need to figure a way to remember what position its in in the table and then just call

update_table_data(NSIndexPath.indexPathForRow(x, inSection:y))

Thoughts on how we might achieve this?

Live reloading for PM Screens

I'm working on it. Should hook into live.

Also, would like to output an info debug when loading the simulator up:

UITableViewCell centre

Hi, I have this code:

# app/views/my_cell.rb
class MyCell < PM::TableViewCell
  def on_load
    apply_style :my_cell

    content = find(self.contentView)
    @title = content.append! UILabel, :my_cell_title
    @segmented = content.append! UISegmentedControl, :segmented_control

    @segmented.segmentedControlStyle = UISegmentedControlStyleBar
    @segmented.insertSegmentWithTitle('One', atIndex: 0, animated: false)
    @segmented.insertSegmentWithTitle('Two', atIndex: 1, animated: false)
  end

  def title=(value)
    @title.text = value
  end
  def title
    @title
  end
end

# app/stylesheets/my_cell_stylesheet.rb
module MyCellStylesheet
  def my_cell_height
    40
  end

  def my_cell(st)
    st.frame = {l: 5, t: 100, w: 80, h: my_cell_height}
    # Style overall view here
  end

  def my_cell_title(st)
    st.frame = { l: 10, fr: 10, centered: :vertical, h: 20 }
    st.font = font.medium
    st.color = color.black
  end

  def segmented_control(st)
    st.frame = { left: 20, fr: 20, centered: :both, h: 30 }
  end
end

Which results in this:

I have two questions, first: shouldn't the segmented_control be horizontally centered?

And second question: if I use this code instead (in the stylesheet):

def segmented_control(st)
    st.frame = { left: 20, fr: 20, centered: :vertically, h: 30 }
end

How is this vertically centered?

What am I doing wrong? If I had to guess, I would say that the view of the cell itself is not filling the whole available space and therefore the segmented_control is misplaced whilst despite centered. Thanks a lot!

Use CDQ generators if included

Currently uses RMQ generic model generators, but should use CDQ's generators instead if it's included.

Idea: progress spinner

We should decided on a progress gem, like JGProgressHUD or whatever, and make a nice wrapper around it in RedPotion. Especially the common stuff.

Review Travis

I'm seeing Travis build failures more regularly, creating an iissue as a reminder to review and fix what I think is an intermittent test. Or at least review and fix the failures

The project is pretty standard. Here's the gemfile:

source "https://rubygems.org"
gem "rake"
gem "motion-cocoapods"
gem "redpotion"
gem "cdq"
gem "afmotion"
gem "newclear" 
gem "ProMotion-form"

gem "ProMotion-map", "~> 0.3"
gem "ProMotion-iap"

gem "bubble-wrap"
gem 'motion-blitz'

Any ideas?

Issue with `on_load` firing more than once

I was working with my existing app and making headway towards using RedPotion and noticed an interesting issue. I had a controller that I converted to a screen and it seemed to be appending my views more than once (3 times to be exact).

I thought that this was totally due to my migration path, but I was able to recreate pretty simply on the sample app of redpotion. If you simply open the home screen and add mp 'on_load HomeScreen' you will see the following result by simply running the app.

Simulate ./build/iPhoneSimulator-8.1-Development/RedPotion.app
(main)> "on_load HomeScreen"
"on_load HomeScreen"
"on_load HomeScreen"

Pretty sure I tracked down the issue - PR coming for this later today.

Idea: "headless" tables

@twerth and I discussed several scenarios related to #63 and infinitered/rmq#232. One of the sticking points is collections or sets of data and how to represent those on a screen. Todd and I agree that tables are underutilized as child views, and I'd like to make that easier.

I have this concept of a "headless" table view. ProMotion makes it easy to make a PM::TableScreen subclass, but what if we could do this in a normal screen:

class ContactScreen < PM::Screen
  def on_load
    append email_view, :emails
  end

  def email_view
    @email_view ||= build_table_view([{
      title: "Email addresses",
      cells: @emails.map do |email|
        {
          cell_class: SomeCustomClass,
          title: email,
          action: :tapped_email,
          arguments: { email: email } 
        }
      end
    }])
  end

  def tapped_email(args={})
    args[:email] # => some email
  end
end

No explicit PM::TableScreen subclass would be necessary. All events would be passed through to the parent screen, and the UITableViewController instance would be automatically built, added as a childViewController, and managed from your current screen instance. These things are usually pretty boilerplate anyway, so it makes sense to have a helper for this.

Thoughts?

Remove default Pods/Gems as needed

A beginner to RubyMotion won't know anything about AFnetworking or CDQ. We'd love the gem to still be fore them. So lets add a few potion tasks to remove CDQ after the fact.

potion remove cdq
postion remove afmotion

Idea: scaffolding generators

Hello! This is a continuation of a conversation that started on Twitter. Just creating this issue to start the conversation around this feature.

It would be really useful to have a scaffolding generator, much like Rails, which would provide the basic CRUD operations. This would also serve as an example of how to wire up views, create forms, and work with CDQ. A simple ToDo list example app would go a long way in helping beginners to learn iOS/ProMotion/RedPotion. I don't know of anything like that.

Another common task is working with an API. Another potential scaffolding generator could be the same CRUD operations using AFMotion instead of CDQ.

Let me know what the next steps would be in implementing this. I'm happy to help. Though I must admit that I'm still relatively new to iOS/RubyMotion development.

Documentation for using CDQ not working

I'm not sure if this is an issue with RedPotion, CDQ or myself being a noob but after running through the CDQ tutorial here http://docs.redpotion.org/en/latest/cookbook/core_data/ I'm getting an error when trying to run the iOS simulator. So far I've uncommented the schema and generated the model files.

*** Starting simulator 2015-07-11 14:56:30.203 todo2[73446:1865241] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'

I've tried this with the iOS 7.0 and the 8.4 simulator. I've even tried recreating a blank project to make sure it wasn't my own code causing it. The app works fine until I make the schema and model files.

I'm using the following gem versions:

RedPotion 1.3.0
ProMotion 2.4.2
CDQ 1.0.3
