use gon in helpers?! about gon HOT 3 CLOSED

It depends on what do you want to do and in what environment) Can you explain more detailed?

from gon.

Yes: I basically want to transport some configuration-options for a query-component(plupload) to a script: Apart from some static variables (like a max_file_size), there are some variables that are infered from the model like:

  file_data_name: [model_object].flatten.pop.class.name.demodulize.underscore.downcase + "[#{model_object_method}]",

The helper will then be called with:

   plupload @image_asset, :asset

and renders the upload-component for the given model/method. The helper should write the generated parameters into the view where the js picks it up.

I could also write the parameter-code from the controller, but with this approach, the controller doesn't even need to know, that its objects are rendered to be uploadable - therefore, the helper needs to call gon.upload_parameters = ....

from gon.

Gon::Helpers constant contains method for render data in views: include_gon. As I can understand - you want to assign some variables in gon in your helper. Then you need to include constant Gon::GonHelpers, which add gon instance method. If it's not enough - you can write your own proxy method to work with gon - you can trace example how it works by debugging simple assign variable in controller action, and I can explain details later.
