include_gon causes nil object error about gon HOT 11 CLOSED

Hey! Thanks for response!

Did you try this on new application or just on your app? What logic in your root action?

from gon.

In my app, I actually never go to the root action / "home" page, since the app is meant to run in Qt webkit, and the Qt application makes URL requests to the Rails app like "http://localhost:3000/[email protected]&password=admin" and then the Rails app would typically respond with the proper webpage.

I didn't try on a new application, just on this app.

The error occurs in the webpage when I test the url and in the Qt app. (If it doesn't work in the webpage, then it definitely won't work in the Qt app - I just want to point out the error doesn't have anything to do with Qt)

from gon.

I'm sorry but I can't reproduce this bug on new rails app, and don't know your environment. If you can do some debug or tests - it will be helpful! And of course it will be super if you can do pull request with tests for this case or fix for this bug :)

Ah, I found out the issue: I was declaring Gon.global variables in ApplicationController where there was a before_filter:

class ApplicationController < ActionController::Base
  protect_from_forgery
  before_filter :authenticate!

  # These are constant variables for clear comparison/code readability across controllers and coffee files.
  # So, when a controller action uses Gon to set a variable, the coffeescript can get the same value reliably.
  # These are enums, essentially
  # these should be what controller sets gon.view to
  Gon.global.OTHER_VIEW = 'other'
  Gon.global.PROJECTS_SHOW = 'projects/show'
  Gon.global.FOLDERS_SHOW = 'folders/show'

What would be the proper place to define these global gon variables?

from gon.

I advice to create some initializer for gon and create global variables there if it's possible (if there no dynamic variables). If not - you should do some singleton method which should check define of global variables and place it before call.

from gon.

Okay, since the variables are static, I should simply put them in config/initializers/mygonfile.rb ? Will it be automatically included?
Thanks!

from gon.

Yes, it should) If all will be ok - please close the issue)

from gon.

Actually the error has to do with setting Gon.global.myvariable anywhere, it seems... when I have it set in an initializer, the error persists. I'm digging around in your code right now, and it all starts here:

gon / lib / gon / helpers.rb

  def include_gon(options = {})
    if variables_for_request_present?
      Gon::Base.render_data(options)
    elsif Gon.global.all_variables.present?
      Gon.clear
      Gon::Base.render_data(options)
    elsif options[:init].present?
      Gon.clear if Gon.all_variables.present?
      Gon::Base.render_data(options)
    else
      ""
    end
  end

The problem might stem from a misunderstanding of your include_gon method... mine has no arguments, yet Gon.clear is still being called (I suspect b/c I set global variables?)

from gon.

Could you clarify your usage section? https://github.com/gazay/gon#usage
I don't understand namespace or init or camel case...

from gon.

I found bug I think, I'll do new version tomorrow

Thanks!

About usage sections - I thought there are all simple - you pass some option to include gon and it's change you end javascript

from gon.

fixed in 3.0.4
