Rails渲染request.referer错误缺少模板

Question

1. 导轨4.2.1
   2. 引导程序3
   3. 简单的形式

我有一个三页的用户编辑（（配置文件，帐户，设置）系统）。

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

我将发布edit_profile.html.erb一些专有信息将被删除。

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>

</ul>
    <%= render 'shared/error_messages' %>

                        </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 class="col-md-4">

            </div>
            <div class="col-md-4">
            </div>
        </div>
    </div>

</div>

edit.html.erb完全相同，只是它具有来自其他所有三个文件的代码。 没有什么不同。

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

以上每个页面上都有4个或更多选项卡。 每个选项卡包含一部分用户表单。 在我的导航中（而不是各个页面上的选项卡），我具有link_to这样的内容。

<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>

然后我在user.controller.rb也有更新

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

结束

如果用户在三个页面之一上犯了错误，则应将其转回到带有验证错误的引用表单页面。

地址栏URL。 在配置文件编辑页面上http://localhost:3000/users/2/edit?form=profile在缺少的模板页面上http://localhost:3000/users/2

完全错误。 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-如果每种编辑模式（profile_controller，account_controller，settings_controller）具有单独的控制器，则无需执行此操作。 将条件逻辑放在控制器动作中并不会带来太多好处，而是可以将逻辑放在路由中，并且控制器动作保持简单。

所以我通过创建三个单独的控制器来做到这一点

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

在routes.rb中，我添加了。

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

然后只需将编辑和更新方法从用户控制器复制到这些新控制器。 在每个视图目录中创建了edit.html.erb ，所有工作都按应有的方式进行。
