Question

当我在<代码>上填写时,js.erb www.un.org/Depts/DGACM/index_french.htm

$( div#rewards_list ).html("<%=
  escape_javascript(render :partial    =>  shared/rewards ,
                           :collection => @rewards,
                           :as => reward,
                           :locals => { :user => @user }
                   )
%>");

但该记录表明:

ActionView::Template::Error (undefined local variable or method `reward  for
  #<#<Class:0xbb395d8>:0xbb3774c>):

在我更新的行动方法中:

def update
  @user   = User.find(params[:user_id])
  @reward = @user.rewards.find(params[:id])

  respond_to do |format|
    if @reward.update_attributes(params[:reward])
      @rewards = @user.rewards

      format.html { redirect_to @user }
      format.js
    else
      flash[:error] = "There is an error while updating the reward, please try again!"

      format.html { redirect_to @user }
    end
  end
end

Answer 1

<代码>:作为的选项,应当作为符号,而不是一个变量(特别是不存在的变量),或许意味着:

$( div#rewards_list ).html("<%= escape_javascript(render :partial =>  shared/rewards , :collection => @rewards, :as => :reward, :locals => {:user => @user}) %>");

我刚刚修改了<代码>:as => Award to :as => :reward。见。 Layouts and Rendering in Railways Guide for details.
