Rails创建动作不起作用 [英] Rails Create Action Not Working

问题描述

我的简单表单不执行POST。我一直在查看，却无法发现问题所在（我确定是在我的路线上）。这是我所拥有的：

My simple form is not doing a POST. I've been looking at this and haven't been able to see what is wrong (I'm sure it's in my routes). Here's what I have:

视图：

views/buyers/new.html.erb

    <%= form_for(@buyer) do |f| %>
            <%= f.text_field :phone %><br />
            <%= f.text_field :make %><br />
            <%= f.text_field :model %><br />
            <%= f.submit %>
          <% end %>

控制器：

BuyersController
  def new
    @title = "Welcome to Car Finder"
    @buyer = Buyer.new
  end 

  def create
    @buyer = Buyer.new(params[:buyer])
    if @buyer.save!
      redirect_to success
    else
      redirect_to :back
    end
   end

路线：

resources :buyers 

耙道：

                    buyers GET    /buyers(.:format)                buyers#index
                           POST   /buyers(.:format)                buyers#create
                 new_buyer GET    /buyers/new(.:format)            buyers#new
                edit_buyer GET    /buyers/:id/edit(.:format)       buyers#edit
                     buyer GET    /buyers/:id(.:format)            buyers#show
                           PUT    /buyers/:id(.:format)            buyers#update
                           DELETE /buyers/:id(.:format)            buyers#destroy

当我提交表单时，它将保留在同一页面上，永远不要执行create动作。下面是来自日志的

When I submit the form, it stays on the same page, never going to the create action. Below is from the log

Started GET "/?..[params]..."
Processing by BuyersController#new as HTML

推荐答案

重新启动服务器可能是明智的。您的问题可能出在持久性级别或 buyer.rb 文件中的验证中。将此添加到_form.html.erb：

It is probably wise to restart your server. You're issue may lie in validations you have at your persistence level or in your buyer.rb file. Add this to the _form.html.erb:

<% if @buyer.errors.any? %>
 <div id="error_explanation">
  <h2><%= pluralize(@buyer.errors.count, "error") %> prohibited this from being saved:   </h2>

  <ul>
  <% @buyer.errors.full_messages.each do |msg| %>
    <li><%= msg %></li>
  <% end %>
  </ul>
 </div>
<% end %>

尝试再次完成请求。查看是否抛出任何错误。解决这些问题。

Try to complete the request again. See if any errors are being thrown. Fix those.
