使用带有 Rails 的 jQuery 时出现“模板丢失”错误

Question

我正在尝试使用编辑帐户页面中的“添加用户头像”链接将头像添加到用户个人资料。

这是 avatars_controller.rb:

def new
  @avatar = Avatar.new

  respond_to do |format|
    format.html # new.html.erb
    format.xml  { render :xml => @avatar }
    format.js
  end
end

def create
  @avatar = @user.avatars.create(params[:avatar])
  respond_to do |format|
    if @avatar.save
      format.html { redirect_to(edit_account_path, :notice => 'Avatar was successfully created.') }
      format.xml  { render :xml => @avatar, :status => :created, :location => @avatar }
      format.js
    else
      format.html { render :action => "new" }
      format.xml  { render :xml => @avatar.errors, :status => :unprocessable_entity }
      format.js
    end
  end
 end

这是我的链接：

<%= link_to "add a new avatar", new_avatar_path%>

路线：

resources :avatars
resources :users do
  resources :avatars
end

views/avatars/create.js.erb：

alert('whoaaa!!!')

我正在使用 rails 3.0.9 并获得：

模板丢失

我快要疯了。请帮忙。

Answer 1

您正在调用 edit 操作并希望呈现 create 模板。这就是重点。

鉴于您的输出，我猜edit 操作正在渲染不存在的new.js.erb 模板。

变化：

<%= link_to "add a new avatar", new_avatar_path%>

与：

<%= link_to "add a new avatar", new_avatar_path, :remote => true %>

实际发出 ajax 请求。
