我为rails安装了gem x-editable：

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

我将该方法添加xeditable?到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

但是还是报错：

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:

我应该在哪里定义方法xeditable?以便它开始工作？

更新：

这是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

这是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

现在我收到新错误：与 相同xeditable?，但使用can?(method undefined)

添加helper_method :xeditable?你的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
