其他父控制器 rails 3.1 中的自定义验证错误表单控制器

本文介绍了其他父控制器 rails 3.1 中的自定义验证错误表单控制器的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我的 rails 应用中有一个 House 模型，它有很多交易.我在房子的展示页面上显示这些交易.当我提交表单时，如果使用 redirect_to，一切正常；但是，如果 Deal 模型存在验证错误，那么我的系统就无法正常工作.如果 Deal 模型存在验证错误.

I have a House model in my rails app that has_many deals. I am displaying these deals on the house's show page. When I submit the form everything works fine if is with redirect_to; however, if there are validation errors on the Deal model, then my system not working fine. If there are validation errors on the Deal model.

在我的routes.rb我有

resources :houses do resources :deals end

在 deals_controller.rb 中，我创建了下一个方法:

In deals_controller.rb I have the next method create:

def create @house = House.find_by_slug(params[:house_id]) @deal = @house.deals.build(params[:deal]) @deal.user = current_user respond_to do |format| if @deal.save format.html { redirect_to @house, :notice => 'Your offer has been created successfully' } format.json { render json: @house, status: :created, location: @house } else format.html { redirect_to @house, :alert => 'Oops, something went wrong. Please try again' } format.json { render json: @house.errors, status: :unprocessable_entity } end end end

redirect_to 工作正常，但是当验证表单模型失败时我无法自定义我的错误消息.

With redirect_to working fine, but I can not custom my error message when fail the validation form model.

@deal.save 失败时我检查了这个方法:

I have check this method when @deal.save fail:

render :template => 'houses/show'

这个方法我在哪里见过在模型验证失败时在 Rails 中呈现评论控制器?

我只想渲染房子的但不适合我，因为表单有一个动作:

I would simply like to render the house's But not working for me, because the form have a action to:

/houses/name-of-house/deals

而不是重定向到/houses/name-of-house/

如何在我的动作表演中从房屋控制器获得表单交易(子)的错误验证?

推荐答案

我有同样的问题.我认为这是 在哪里渲染的副本模型验证失败时 Rails 中的评论控制器? - 我在那里添加我自己的响应.

I have the same problem. I think this is a duplicate of Where to render comments controller in Rails on model validations failure? - I am adding my own response there instead.
