rails-url-helpers-lab's Introduction

Rails URL Helpers Lab

Objectives

Generate URLs using route helpers
Draw routes with implicit and explicit names using :as
Draw routes with variables
Generate URLs using route helpers that require variables

Instructions

In this lab you will be building out the Student management dashboard for the Flatiron School by starting to integrate the ability to link between pages. Two tests are currently passing, and the rest need implementation code to start passing. In order to complete this lab, you will need to complete the following tasks:

A user should be able to navigate to /students to view all of the students.
A user should be able to click the student's name on the index page and be taken to that specific student's show page.
Create a new boolean attribute called active in the students table. (HINT: You might have to search around for the best way to set a (ahem) default value (should default to false).)
A user should be able to go to /students/:id/activate to toggle their active attribute between true and false. (This is just the activate route, and not a actual view.)
Read the failing tests and modify the code until they pass.

Keep in mind

Make sure the show path is /students/:id, where :id is a route variable.
Call the Student class instance method to_s on each of the students on the index page so that each student element contains their first and last name.
On the student index page, test out all three different link_to argument options, e.g.: link_to "post", "/post/#{post.id}", link_to("post", post_path(post.id)), link_to("post", post_path(post)).

rails-url-helpers-lab's Issues

Suggestion for "activate page" clarity

Issue : Confusion due to spec/recent labs+readings

Reasoning : The spec uses "Activate page" alongside the index and show pages, which makes it seem like the "activate page" is an actual html.erb view (as those views are what has been discussed in all of the recent labs/readings).

Suggestion : Make it clearer that the "activate page" is actually just the "activate route" and not an actual view.

Error in student_spec file

Line 27 of student_spec.rb file, student_path should be students_path.

A small edit to the README is needed

I am guessing that this lab has been updated recently. The README needs to be ever-so-slightly updated.

It says that "four tests are currently passing". However, when I first ran learn on this lab, only TWO tests were passing: "Student can be created" and "Student has a to_s instance method".

As far as I can tell right now, that's the only thing that needs to be fixed. Thanks for looking into this!

Update: I just fixed this in a pull request.

---Sdcrouse

student_path(@student) used in the tests for navigation is undefined

spec\features\student_spec.rb

Rails.application.routes.draw do
  resources :students, only: :index

  # This show route can be refactored into the above resources method call, like so:
  # resources :students, only: [:index, :show]
  # However, for the sake of this lab and seeing how you can pass params through
  # the route, we'll keep it explicit for now and refactor later.
  get "students/:id", to: "students#show"
end

These comments imply that line 2 and 8 are the equivalent to line 5 when in reality the method student_path (used in the tests) isnt generated by line 2 or 8, only on line 5.

test

  it 'renders properly' do
    visit student_path(@student)
    expect(page.status_code).to eq(200)
  end

Can't do lab - broken every step of way

Comes in broken. Bundle install? NAHHHH

Web Console is activated in the test environment, which is
usually a mistake. To ensure it's only activated in development
mode, move it to the development group of your Gemfile:

gem 'web-console', group: :development

If you still want to run it the test environment (and know
what you are doing), put this in your Rails application
configuration:

config.web_console.development_only = false

**But it came this way:

Gemfile:
...
group :development, :test do
gem 'byebug'
gem 'web-console', '> 2.0'
gem 'spring'
gem 'rspec-rails', '> 3.0.0'
gem 'factory_girl_rails'
gem 'capybara'
gem 'database_cleaner'
end

So I'll follow the suggestion, change it to:

group :development, :test do
gem 'byebug'
gem 'spring'
gem 'rspec-rails', '~> 3.0.0'
gem 'factory_girl_rails'
gem 'capybara'
gem 'database_cleaner'
end

gem 'web-console', '~> 2.0', group: :development

and run try Learn again

Students have been googling and creating their own secrets.yml file, setting the secret token to resolve the issue.

The "activate page" part needs to be modified or removed

Hi. I got a little stuck when going through this lab.

When I got to the "activate page" part, it became clear that I needed to redirect to the '/students/:id' route after toggling the student's "active" status on or off. There was just one problem: none of the lessons up to this point have covered how to redirect with Rails (unless that was introduced in the Video Review near the start of the Rails module). I was able to figure it out after some research, thankfully.

I'm not sure whether the "activate page" part should be modified or removed altogether. I'm guessing that its purpose was to have us practice using the :as option in our routes. Either way, thanks a lot for looking into this!
