Ruby on rails Rails-可以在RJS文件中使用ruby代码吗？

可以在RJS文件中使用ruby代码吗

例如，destroy.js.rjs文件

这是从具有

  def destroy
    @viewer = Viewer.find(params[:id])
    @viewer_registry = Registry.find(@viewer.registry_id)
    @viewer.destroy
    flash[:notice] = "Viewer deleted"
    @template = params[:template]
    params[:template] = nil
    respond_to do |format|
      format.html { redirect_to registry_path(@viewer_registry) }
      format.js
    end
  end

因此，在AJAX调用中，RJS文件用于响应，它根据调用销毁操作的模板给出不同的响应

此时，AJAX调用被发出，记录被销毁，然后什么都不会发生，不管哪个模板调用销毁操作。 所以我想知道它是否仅仅因为我不能在RJS文件中使用ruby代码而不起作用。有什么想法吗？还是我完全做错了

谢谢

对，我重新定义了destroy函数，使其看起来像这样：

  def destroy
    #is this bad because its not linked to current_user?
    #how would you even set it to be relational to current_user? 
    @viewer = Viewer.find(params[:id])
    @viewer_registry = Registry.find(@viewer.registry_id)
    @viewer.destroy
    flash[:notice] = "Viewer deleted"
    respond_to do |format|
      format.html { redirect_to registry_path(@viewer_registry) }
      format.js {
        if params[:template] == "viewer"
          render :action => "viewer_destroy.js.rjs"
        else
          render :action => "destroy.js.rjs"
        end
      }
    end
  end

所以我有2个RJS文件，根据传入的模板名使用不同的文件。 耶

  def destroy
    #is this bad because its not linked to current_user?
    #how would you even set it to be relational to current_user? 
    @viewer = Viewer.find(params[:id])
    @viewer_registry = Registry.find(@viewer.registry_id)
    @viewer.destroy
    flash[:notice] = "Viewer deleted"
    respond_to do |format|
      format.html { redirect_to registry_path(@viewer_registry) }
      format.js {
        if params[:template] == "viewer"
          render :action => "viewer_destroy.js.rjs"
        else
          render :action => "destroy.js.rjs"
        end
      }
    end
  end
