煉油廠CMS查詢 - content_for渲染時出現NoMethodError：正文內容

Question

我在我的應用程序中使用'refinerycms-queries'gem在我的聯繫頁面上顯示查詢。

我得到的問題是，儘管我可以在我的其他頁面上使用<%= raw @page.content_for(:body) %>代碼來呈現內容，但我不知道爲什麼我在查詢＃新視圖中獲得此代碼。也許有人可以幫助我更快地解決這個問題，因爲我已經在互聯網上找了幾個小時尋找答案並查看源代碼。

這是錯誤：

NoMethodError in Refinery/inquiries/inquiries#new 
undefined method `content_for' for nil:NilClass 

Extracted source (around line #3): 

1: <% content_for :body do %> 
2:  <div> 
3:  <%= raw @page.content_for(:body) %> 
4:  </div> 
5: <% end %> 
6: 

我不得不提到我是一個有點新的煉油廠和回報率。

這是我的煉油廠/查詢/查詢/ new.html.erb文件：

<% content_for :body do %> 
    <div class="contact"> 
     <%= raw @page.content_for(:body) %> 
    </div> 
<% end %> 

<% content_for :body_content_left do %> 
    <div class='inquiries'> 
     <%= form_for [refinery, :inquiries, @inquiry] do |f| %> 
      <%= render :partial => "/refinery/admin/error_messages", 
        :locals => { 
          :object => @inquiry, 
          :include_object_name => true 
        } %> 
      <div class="field"> 
      <%= f.required_label :name, :class => 'placeholder-fallback' %> 
      <%= f.text_field :name, :class => 'text', :required => 'required', :placeholder => t('name', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class="field"> 
      <%= f.required_label :email, :class => 'placeholder-fallback' %> 
      <%= f.email_field :email, :class => 'text email', :required => 'required', :placeholder => t('email', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class="field"> 
      <%= f.label :phone, :class => 'placeholder-fallback' %> 
      <%= f.text_field :phone, :class => 'text phone', :placeholder => t('phone', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class='field message_field'> 
      <%= f.required_label :message, :class => 'placeholder-fallback' %> 
      <%= f.text_area :message, :rows => 8, :required => 'required', :placeholder => t('message', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class="actions"> 
      <%= f.submit t('.send') %> 
      </div> 
     <% end %> 
    </div> 
<% end %> 
<%= render :partial => "/refinery/content_page" %> 

這是我inquiries_controller.rb：

module Refinery 
    module Inquiries 
    class InquiriesController < ::ApplicationController 

     before_filter :find_page, :only => [:create, :new] 

     def thank_you 
     @page = ::Refinery::Page.find_by_link_url("/contact/thank_you") 
     end 

     def new 
     @inquiry = ::Refinery::Inquiries::Inquiry.new 
     end 

     def create 
     @inquiry = ::Refinery::Inquiries::Inquiry.new(params[:inquiry]) 

     if @inquiry.save 
      if @inquiry.ham? 
      begin 
       ::Refinery::Inquiries::InquiryMailer.notification(@inquiry, request).deliver 
      rescue 
       logger.warn "There was an error delivering an inquiry notification.\n#{$!}\n" 
      end 

      begin 
       ::Refinery::Inquiries::InquiryMailer.confirmation(@inquiry, request).deliver 
      rescue 
       logger.warn "There was an error delivering an inquiry confirmation:\n#{$!}\n" 
      end if ::Refinery::Inquiries::Setting.send_confirmation? 
      end 

      redirect_to refinery.thank_you_inquiries_inquiries_path 
     else 
      render :action => 'new' 
     end 
     end 

     protected 

     def find_page 
     @page = ::Refinery::Page.find_by_link_url("/contact") 
     end 

    end 
    end 
end 

這裏是配置/ routes.rb中部分是由'refinerycms-queries'創建的寶石：

Refinery::Core::Engine.routes.draw do 
    namespace :inquiries, :path => '' do 
     get '/contact', :to => 'inquiries#new', :as => 'new_inquiry' 

     resources :contact, 
       :only => :create, 
       :as => :inquiries, 
       :controller => 'inquiries' do 
     get :thank_you, :on => :collection 
     end 

     namespace :admin, :path => 'refinery' do 
     resources :inquiries, :only => [:index, :show, :destroy] do 
      get :spam, :on => :collection 
      get :toggle_spam, :on => :member 
     end 

     scope :path => 'inquiries' do 
      resources :settings, :only => [:edit, :update] 
     end 
     end 
    end 
    end 

Answer 1

看起來像我已經找到了問題。

原來，從inquiries_controller ::煉油廠:: Page.find_by_url方法返回零，我不得不重寫find_page和thank_you方法是這樣的：

def thank_you 
    @page = ::Refinery::Page.find_by_path("/contact/thank_you") 
    end 

    def find_page 
    @page = ::Refinery::Page.find_by_path(/contact") 
    end 

爲了使：身體： side_body內容將在我的聯繫人視圖中呈現。我也注意到，通過這種修改，並不需要在我的煉油廠/ queries/queries/new.html.erb文件中明確指定呈現content_for（：body）。

所以新的觀點看起來像一個默認的寶石：

<% content_for :body_content_left do %> 
    <div class='inquiries'> 
     <%= form_for [refinery, :inquiries, @inquiry] do |f| %> 
      <%= render :partial => "/refinery/admin/error_messages", 
        :locals => { 
          :object => @inquiry, 
          :include_object_name => true 
        } %> 
      <div class="field"> 
      <%= f.required_label :name, :class => 'placeholder-fallback' %> 
      <%= f.text_field :name, :class => 'text', :required => 'required', :placeholder => t('name', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class="field"> 
      <%= f.required_label :email, :class => 'placeholder-fallback' %> 
      <%= f.email_field :email, :class => 'text email', :required => 'required', :placeholder => t('email', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class="field"> 
      <%= f.label :phone, :class => 'placeholder-fallback' %> 
      <%= f.text_field :phone, :class => 'text phone', :placeholder => t('phone', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class='field message_field'> 
      <%= f.required_label :message, :class => 'placeholder-fallback' %> 
      <%= f.text_area :message, :rows => 8, :required => 'required', :placeholder => t('message', :scope => 'activerecord.attributes.refinery/inquiries/inquiry') %> 
      </div> 
      <div class="actions"> 
      <%= f.submit t('.send') %> 
      </div> 
     <% end %> 
    </div> 
<% end %> 
<%= render :partial => "/refinery/content_page" %> 

希望這有助於如果有人遇到同樣的問題。

問題是您的相關文件缺少@page的定義自動控制器的行爲（在你的案例中「新」和「創造」）。我可以看到@inquiry實例化。嘗試添加語句

@page = ::Refinery::Page.find_by_link_url("/contact") 

無論你在'新'和'創建'的InquriesController行動。

我有點好奇，你使用的是什麼版本的煉油廠？ （奇怪的是refinerycms-queries gem如何在routes.rb中生成一個內容，假設它是一個可掛載的引擎）。
