其他模型的Rails表单 [英] Rails Form for another model

问题描述

我在页面/联系人中有一个表单，想将数据发送到另一个称为ContactForm的模型而不是Pages模型，所以我想这超出了基本约定.看起来像这样:

I have a form in pages/contact and want to send the data to another model called ContactForm instead of Pages model, so i guess this is outside the basic convention.. it looks like this:

<%= form_for @contact_form, url: pages_contact_path, :method => :post do |f| %>
...
...
<% end %>

class PagesController < ApplicationController

    def contact
        @contact_form = ContactForm.new(contact_form_params)    
    end
end

我创建了这条路线

  post 'pages/contact' => 'pages#contact'

看起来一切正常，但是没有数据记录.在本地服务器上，我可以看到正在处理POST，但未执行任何SQL事务.为什么?

and it all seems to work fine, but no data is recorded. In the local server i can see is processing the POST but is not doing any SQL Transaction.. why??

推荐答案

在本地服务器上，我可以看到正在处理POST，但没有执行 任何SQL事务..为什么?

In the local server i can see is processing the POST but is not doing any SQL Transaction.. why?

只要不请求任何事务，就不执行SQL. contact_form操作的作用是为变量分配参数，但是不要求对此变量进行验证并将其保存到数据库中.因此，它只是传递给视图...

No SQL is done as long as no transaction is requested. What your contact_form action does is assigning parameters to a variable, but this variable is not requested to be validated and saved to your database. So it is simply passed over to the view...

您所感兴趣的是:

@contact_form = ContactForm.new(contact_form_params)
if @contact_form.save
  # render success
else
  # render errors
end
