滑軌渲染request.referer錯誤丟失模板

Question

1. 滑軌4.2.1
2. 引導3
3. Simple_form

我有三個頁面用戶編輯，（配置文件，帳戶，設置）系統。

app/view/users 
    _form.html.erb 
    edit.html.erb 
    edit_account.html.erb 
    edit_profile.html.erb 
    edit_settings.html.erb 
    new.html.erb 
    show.html.erb 

我會發布edit_profile.html.erb一些專有信息將被刪除。

edit_profile.html.erb

<% provide(:title, "Edit Profile") %> 

<div> 
    <ul class="nav nav-tabs" role="tablist"> 
    <li role="presentation" class="active"><%= link_to 'Profile', "#profile", "aria-controls" => "profile", "role" => "tab", "data-toggle" => "tab" %></li> 
    <li role="presentation"><%= link_to 'Bio', "#bio", "aria-controls" => "bio", "role" => "tab", "data-toggle" => "tab" %></li> 
    <li role="presentation"><%= link_to 'My Websites', "#websites", "aria-controls" => "websites", "role" => "tab", "data-toggle" => "tab" %></li> 
    <li role="presentation"><%= link_to 'Upload Photos', "#photos", "aria-controls" => "photos", "role" => "tab", "data-toggle" => "tab" %></li> 
    <li role="presentation"><%= link_to 'Upload Videos', "#videos", "aria-controls" => "videos", "role" => "tab", "data-toggle" => "tab" %></li> 
</ul> 
    <%= render 'shared/error_messages' %> 
<div class="tab-content"> 
    <div role="tabpanel" class="tab-pane active" id="profile"> 
     <div class="row"> 
      <div class="col-md-8"> 
       <%= simple_form_for @user, url: {action: "update"} do |f| %> 
        <div class="form-inputs form-inline well"> 
         <legend>Tell us about yourself!</legend> 
         <%= f.input :birthdate, as: :date, 
          start_year: Date.today.year - 18, 
          end_year: Date.today.year - 100, 
          order: [:month, :day, :year], 
          :label=> 'Date of Birth', 
          :required => true %> 
         <br>    
         <%= f.input :age_valid, 
          :as => :boolean, 
          :label => false, 
          :checked_value => true, 
          :unchecked_value => false, 
          :inline_label => 'I am 18 years of age or older.' %> 
        </div> 
        <div class="form-actions"> 
         <ul class="list-inline"> 
          <li><%= f.button :submit, 'Update Profile', :class=> "btn btn-primary btn-sm" %></li> 
         </ul> 
        </div> 
       <% end %>  
      </div> 
      <div class="col-md-4"> 
       <ul class="h6c"> 
        <li>Q. How old do I need to be?</li> 
        <li>You need to be at least 18 years old.</li> 
       </ul> 
      </div> 
     </div> 
    </div> 

    <div role="tabpanel" class="tab-pane" id="bio"> 
     <div class="row"> 
      <div class="col-md-8"> 
      </div> 
      <div class="col-md-4"> 
      </div> 
     </div> 
    </div> 

    <div role="tabpanel" class="tab-pane" id="websites"> 
     <div class="row"> 
      <div class="col-md-8"> 
      </div> 
      <div class="col-md-4"> 
      </div> 
     </div> 
    </div> 

    <div role="tabpanel" class="tab-pane" id="photos"> 
     <div class="row"> 
      <div class="col-md-8"> 
      </div> 
      <div class="col-md-4"> 
      </div> 
     </div> 
    </div> 

    <div role="tabpanel" class="tab-pane" id="videos"> 
     <div class="row"> 
      <div class="col-md-8"> 
      </div> 
      <div class="col-md-4"> 
      </div> 
     </div> 
    </div> 

</div> 

的edit.html.erb是完全一樣的，除了它具有從所有其他三個文件相結合的代碼。它沒有什麼不同。

在user.controller.rb

def edit 
    @user = User.find(params[:id]) 
    case params[:form] 
     when "profile" 
     render "edit_profile" 
     when "account" 
     render "edit_account" 
     when "settings" 
     render "edit_settings" 
     else 
     render :action => :edit 
    end 
end 

在上述各頁上有4組或更多的標籤。每個選項卡包含一部分用戶表單。在我的導航欄（不是各個頁面上的標籤），我有link_to這樣。

<li><%= link_to 'My Profile', current_user %></li> 
<li><%= link_to 'Write' %></li> 
<li><%= link_to 'Upload Photos', edit_user_path(current_user, :form => "profile") %></li> 
<li><%= link_to 'Upload Videos', edit_user_path(current_user, :form => "profile") %></li> 
<li><%= link_to 'Edit My Profile', edit_user_path(current_user, :form => "profile") %></li> 
<li><%= link_to 'My Settings', edit_user_path(current_user, :form => "settings") %></li> 
<li><%= link_to 'My Account', edit_user_path(current_user, :form => "account") %></li> 

然後，我有更新也在user.controller.rb

def update 
    @user = User.find(params[:id]) 
    if @user.update_attributes(user_params) 
     flash[:success] = "Profile updated" 
     redirect_to @user 
    else 
     render request.referer <---- this gives me template missing error. 
     **render "edit"** <---- this doesn't work either as it takes me to the wrong page 
    end 

末

如果用戶對三頁的一個錯誤就應該呈現回用指表單頁面驗證錯誤就可以了。

地址欄網址。 在配置文件編輯頁http://localhost:3000/users/2/edit?form=profile 關於缺少模板頁面http://localhost:3000/users/2

完整的錯誤。 Missing template http://localhost:3000/users/2/edit?form=profile with {:locale=>[:en], :formats=>[:html], :variants=>[], :handlers=>[:erb, :builder, :raw, :ruby, :coffee, :jbuilder]}. Searched in: * "D:/Development/projects/#/app/views"

Answer 1

注意 - 如果您爲每種編輯模式（profile_controller，account_controller，settings_controller）都有單獨的控制器，則不需要執行此操作。把條件邏輯放在控制器動作中並沒有給你帶來太大的幫助 - 相反，你會把邏輯放在路由中，控制器動作保持簡單。

所以我創建了三個獨立的控制器

rails g controller account rails g controller setting rails g controller profile

在我加入的routes.rb這樣做。

resources :profile, :only => [:edit, :update] 
resources :account, :only => [:edit, :update] 
resources :settings, :only => [:edit, :update] 

然後剛剛將編輯和更新方法從用戶控制器複製到這些新的控制器。在每個視圖目錄中創建了edit.html.erb，並且所有工作都按照應有的方式進行。
