Question

Rails 4.2.1
1. Bootstrap 3
2. Simple_form

我有三页用户编辑，（个人资料，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>

edit.html.erb完全相同，只是它包含来自所有其他三个文件的代码。它没有什么不同。

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

上述每个页面上都有4个或更多标签。每个选项卡包含一部分用户表单。在我的导航中（不是单个页面上的标签），我有这样的link_to。

<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

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

端

如果用户在三个页面中的一个页面上出错，则应该回显到引用表单页面，并在其上显示验证错误。

地址栏网址。在个人资料编辑页面http://localhost:3000/users/2/edit?form=profile 缺少模板页面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 - 如果您为每种编辑模式（profile_controller，account_controller，settings_controller）都有单独的控制器，则不必执行此操作。将条件逻辑放在控制器动作中并没有太多帮助 - 而是将逻辑放在路径中，控制器动作保持简单。

所以我通过创建三个独立的控制器

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，所有这些都按照应有的方式工作。

Rails渲染request.referer错误缺少模板
