问题

I installed the gem x-editable for rails:

# x-editable
gem 'x-editable-rails'

I added the method xeditable? to the ActionController:

  # Add a helper method to your controllers to indicate if x-editable should be enabled.
  def xeditable?
    true # Or something like current_user.xeditable?
  end

But still getting an error:

ActionView::Template::Error (undefined method `xeditable?' for #<#<Class:0x007f9012e30f68>:0x007f9012ee9e78>):
    14: 
    15:     .panel-body
    16:       /a.doc_title.editable id='doc_title_12345' data-name="doc[title]" data-title="Enter doc title" data-type="text" data-url='/docs/12345' href='#doc_title_12345' = doc.title
    17:       = editable doc, :title
    18:

Where should I define the method xeditable? so that it starts working?

Update:

This is application_controller.rb :

class ApplicationController < ActionController::Base

  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

end

This is application_helper.rb :

module ApplicationHelper
  # Add a helper method to your controllers to indicate if x-editable should be enabled.
  def xeditable?
    true # Or something like current_user.xeditable?
  end
end

Now I get new error: same as xeditable?, but with can? (method undefined)

回答1:

Add helper_method :xeditable? in your ApplicationController.rb:

class ApplicationController < ActionController::Base

  helper_method :xeditable?

  # Prevent CSRF attacks by raising an exception.
  # For APIs, you may want to use :null_session instead.
  protect_from_forgery with: :exception

  # Add a helper method to your controllers to indicate if x-editable should be enabled.
  def xeditable?
    true # Or something like current_user.xeditable?
  end

end
