爲什麼x-editable-rails gem拋出一個錯誤：未定義的方法`xeditable？'？

Question

我安裝了導軌寶石X編輯：

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

我添加的方法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 

但仍得到一個錯誤：

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: 
    app/views/docs/_single_doc_in_accordion.html.slim:17:in `_app_views_docs__single_doc_in_accordion_html_slim__2506304306156466629_70128411437560'

凡應我定義方法xeditable?以便它開始工作？

更新：

這是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 

這是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 

現在，我得到新的錯誤：同xeditable?，但can?（方法未定義）

Answer 1

添加helper_method :xeditable?在您的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
