javascript ruby-on-rails forms post polymer

Javascript 缺少用于创建的模板。内部服务器错误-聚合表单保存到数据库,javascript,ruby-on-rails,forms,post,polymer,Javascript,Ruby On Rails,Forms,Post,Polymer,我正在创建一个用于数据收集的表单，我正在尝试使用Polymer实现该表单我已经尝试通过将一个按钮绑定到某个JQuery来实现提交，以提交表单，并使用Rails自己的提交表单帮助器，但没有效果。错误消息非常模糊，没有让我深入了解问题据我所知，它试图呈现create.html.erb的原因是，如果操作失败，它将尝试呈现名称与该操作匹配的视图。我还包括了在create操作中保存到DB失败时重定向到/new操作，但是这似乎不起作用我还多次检查了参数的结构，它们的格式似乎正确有人能看出哪里出了问

控制器：

class MonumentsController < ApplicationController

  def new
    @monument = Monument.new 
  end

  def create
    @monument = Monument.new(monument_params)

    if @monument.save
      flash[:success] = "Monument created successfully!"
    else
      flash[:error] = "Failed to create monument entry!"
      render "monuments/new"
    end
  end

  private

    def monument_params
      params.require(:monument).permit(:site_name, :visit_date, 
        :parish, :designation_no, :her_no, :site_type, :description,
        :condition, :current_management, :condition_trend, :trend_notes,
        :vulnerability
        )
    end
end

类纪念碑控制器

问题在于：

if(monument.save)
   flash[:success] = "Monument created successfully!"
   //nothing
else
   flash[:error] = "Failed to create monument entry!"
   render "monuments/new"
end

正好在

//nothing

部分

当控制器中的某个动作退出而不调用redirect或render rails时，假定您希望以与动作名称相同的名称呈现视图，例如，如果您有动作名称

hello

，并且该动作退出而不调用render或redirect，则将呈现视图

hello.erb.html

，在您的例子中，操作名称是

create

，因此它查找view

create.erb.html

我假设如果纪念碑被成功保存，您希望重定向到另一个页面，如果是这样，那么在

nothing

部分调用

redirect\u to

，在那里您希望重定向

如果你想做另一件事（可能你想呈现json响应等），然后调用render with anything，如果你想退出而不呈现任何内容，那么你可以编写

render nothing:true

，或者使用

head

方法生成没有内容的HTTP头。
