Rails的form_for呈现部分form_for列表值而不提交给数据库，但现在2提交 [英] Rails form_for renders partial form_for to list values without submitting to DB, but now 2 submits

问题描述

我有一个简单的显示器 - form_for一个应用程序，它呈现另一个带有form_for的部分来显示教育资格。部分是多态的。所以，现在我有2个提交，主要提交根本没有回应和部分作品....为什么？请注意，代码适用于一条记录，但需要按部分表单提交。请帮助。

 <％= bootstrap_form_for @application do | f | ％GT; 
< div class =panel panel-default> 
< div class =panel-heading>教育：< / div> 
< div class =panel-body> 
 <％=呈现部分：degrees / form，：locals => {：degreeable => @application，：f => f}％> <峰; br> 
 <％= f.link_to（fa_icon'plus'）。to_s +Add Another Qualification，render（：partial =>'degrees / form'，：locals => {：degreeable => @job，：f => f}），class：btn btn-primary％> 
< / div> 
< / div> 
<％end％> 
  

部分form_for是:(注意：我甚至拿出submit并在主表单上使用link_to，如图所示以上但仍无效。

 <％= form_for [degreeable，Degree.new]，：url => {： action =>index} do | f |％> 
< div class =form-group}> 
<％= f.select：level，options_for_select（Application：包括：Select Degree，class：'span-2'％> 
<％= f.text_field：description，：class =>'span5' > 
< / div> 
 f.submitAdd Another Degree，class：'btn btn-primary'
<％end％> 
  

所需的行为必须是：

1. 部分显示，显示带有学士/硕士/博士学位的投递箱和
   另一个文本字段以接受资质名称。


2. 按钮/链接 - '添加更多资格'给列出资格条件而不提交给DB。


3. 只有主表单按钮应该最终将申请表格提交给DB。

我向经验丰富的开发人员提出的问题：

帮助列在主表单上。如果是的话，如何帮助。所有的AJAX代码，我找到了SO和谷歌提交数据库，而不是简单地列出。

<2>替代重新部分再次用主窗体中的按钮可以提交部分帮助简单列出值？

解决方案

好的，我终于解决了这个问题，这对未来的访问者会有帮助。通过进行2次更改，两个想法都被记入了Stackoverflow开发人员的2个不同的问题： -
$ b

1. Form_for在不同部分中输入和提交按钮 - @Anand


2. Rails将form_for对象传递给partial - @ D.Patrick
3. 
   

Thx给你们俩。所以，最后我现在使用render调用的主窗体看起来如下：

 <％= bootstrap_form_for @application do | f | ％GT; 
 *许多其他应用程序字段，但在这里无关。* 
< div class =panel panel-default> 
< div class =panel-heading>教育：< / div> 
< div class =panel-body> 
 <％@form = f％> 
 <％=呈现部分：degrees / form，：locals => {：degreeable => @application，：f => @form}％> <峰; br> 
 <％= f.link_to（fa_icon'plus'）。to_s +Add Another Qualification，render（：partial =>'degrees / form'，：locals => {：degreeable => @application，：f => f}），class：btn btn-primary％> 
< / div> 
< / div> 
<％= f.submit class：btn btn-primary btn-outline btn-sm％> 
<％end％> 
  

和呈现的部分形式：

 <％= f.fields_for [degreeable，Degree.new]，：url => {：action => index} do | ff | ％GT; 
< div class =form-group}> 
 <％= ff.select：level，options_for_select（JApplication :: EDUCATION，params [：level]），include_blank：Select Degree，class：'span-2'％> 
 <％= ff.text_field：description，：class => 'span5'％> 
< / div> 
 <％ff.submitAdd Another Degree，class：'btn btn-primary'％> 
<％end％> 
  

但是我仍然坚持使用JS / JQuery的点击按钮来列出部分fields.Have发布了这个问题现在在StackOverflow上 。

I have a simple display - form_for an application that renders another partial with form_for for displaying education qualifications. The partial is polymorphic. So, now I have 2 submits, the main submit simply doesn't respond and partial works....why?? Please note that code works well for one record but with pressing partial form submit. Please help.

<%= bootstrap_form_for @application do |f| %>
    <div class="panel panel-default">
      <div class="panel-heading"> Education: </div>
      <div class="panel-body">
        <%= render partial: "degrees/form", :locals => { :degreeable => @application, :f => f }  %> <br>
        <%= f.link_to (fa_icon 'plus').to_s + " Add Another Qualification ", render(:partial => 'degrees/form', :locals => { :degreeable => @job, :f => f }), class: "btn btn-primary" %>
      </div>
    </div>
  <% end %>

Partial form_for is: (Note: I even took out submit and used a link_to on main form as shown above but still no effect.

<%= form_for [degreeable, Degree.new], :url => { :action => "index" } do |f| %>
  <div class = "form-group" }>
    <%= f.select :level, options_for_select(Application::EDUCATION, params[:level]), include_blank: "Select Degree", class: 'span-2' %>
    <%= f.text_field :description, :class => 'span5' %>
  </div>
 f.submit "Add Another Degree", class: 'btn btn-primary'
<% end %>

The desired behaviour must be:

1. partial displayed to show drop box with Bachelor/Master/Ph.D and another text field to accept name of qualification.
2. a button/link - 'Add more qualifications' to list qualifications without submitting to DB.
3. Only main form button should finally submit form for application into DB.

My questions to experienced developers:

1.Can AJAX in partial help list down on main form. if yes, how pls help. All AJAX code I find on SO and google submit in DB and not to simply list down.

2.Instead of reloading partial again with a button from main form can submit of partial help in simply listing down values?

解决方案

Ok so I finally did resolve it and this will be helpful for future visitors. By making 2 changes both ideas are credited to Stackoverflow developers for 2 different questions:-

1. Form_for inputs and submit button in different partials - @Anand
2. Rails passing form_for object to partial - @D.Patrick

Thx to both of you. So, finally my main form with render call now looks:

   <%= bootstrap_form_for @application do |f| %>
      *Many other application fields but irrelevant here.*
      <div class="panel panel-default">
        <div class="panel-heading"> Education: </div>
        <div class="panel-body">
          <% @form = f %>
          <%= render partial: "degrees/form", :locals => { :degreeable => @application, :f => @form }  %> <br>
          <%= f.link_to (fa_icon 'plus').to_s + " Add Another Qualification ", render(:partial => 'degrees/form', :locals => { :degreeable => @application, :f => f }), class: "btn btn-primary" %>
        </div>
      </div>
    <%= f.submit class: "btn btn-primary btn-outline btn-sm" %>
  <% end %>

and rendered partial form:

    <%= f.fields_for [degreeable, Degree.new], :url => { :action => "index" } do |ff| %>
  <div class = "form-group" }>
    <%= ff.select :level, options_for_select(JApplication::EDUCATION, params[:level]), include_blank: "Select Degree", class: 'span-2' %>
    <%= ff.text_field :description, :class => 'span5' %>
  </div>
   <% ff.submit "Add Another Degree", class: 'btn btn-primary' %>
<% end %>

But am still stuck with JS/JQuery of click on button to list partial fields.Have posted the question now on StackOverflow.
