form_for渲染获取而不是发布，使用rails [英] form_for renders get rather than post, using rails

问题描述

我有一个很长的表单，可以自动填充来自我们数据库的信息（基于用户提供的部分信息）。当用户验证信息并重新提交表单时，信息应该保存为用户。表单 - qualifying_events - 是视图/共享文件夹中的一部分。自动填充它的数据由qualifying_events_controller作为create方法的一部分呈现。该部分被呈现用于在由用户控制器呈现的视图/用户页面中进行验证。由用户输入的初始部分信息 - 在同一页面上的相似部分 - 正确保存。以下是表单的顶部：

 < form class =form-inline> 
 <％= form_for（@qualifying_event）do | f | ％GT; 
 <％= render'shared / error_messages'，object：f.object％> 
< div> 
< div class =form-group col-sm-12 text-centerstyle =margin-bottom：5px;>< h5> 
< div> 
< li style =list-style-type：none; float：left; display：none; visibility：hidden;> 
<％= current_user％> 
< / li> 
< / div> 
< div> 
< li style =list-style-type：none; float：left;> 
<％= f.label：class_date％>< br /> 
 <％= f.text_area：class_date，autofocus：true％> 
< / li> 
< / div> 
  

以下是错误讯息：

 没有路线匹配[GET]/ qualifying_events
  

我已经尝试了：

1.明确地向config / routes文件添加一个路由，尽管它已经显示了我是否运行了rake路由：

  post'qualifying_events_path'=> 'qualifying_events＃create'
  

2.将form_for语言改为显式调用'post'：

 <％= form_for（@qualifying_event，url：qualifying_events_path，method：=> post） | F | ％GT; 
  

我仍然收到相同的错误讯息。由于我有其他形式使用相同的代码保存到数据库，因此当从数据库填充表单并想重新保存信息时，我必须假设进行了一些更改。我使用的是设计宝石，所以我看着注册＃编辑代码，希望我可以按照以下格式：

 < ％= form_for（resource，as：resource_name，url：registration_path（resource_name），html：{method :: put}）do | f | ％GT; 
  

不幸的是，这种方法也没有奏效。

$ b $ p

对于'完整性'，以下是qualifying_events_controller代码：

  def创建
 @user = current_user 
 @qualifying_event = current_user.qualifying_events.build（qualifying_event_params）
 
如果@ qualifying_event.validated.nil？ 
＃将来自current_user的部分课程信息与表中的记录进行匹配
 
＃获取部分记录的信息
 active_date = @ qualifying_event.class_date 
 active_course = @ qualifying_event.course_id 
 active_sponsor = @ qualifying_event.sponsor_name 
 
＃在class_date，course_id和sponsor_name上匹配
 @qualifying_event = QualifyingEvent.new 
 @ qualifying_event.assign_attributes（QualifyingEvent。
其中（（class_date =：class_date AND course_id = course_id）
 OR（class_date =：class_date AND sponsor_name =：sponsor_name）
 OR（course_id =：course_id AND sponsor_name =：sponsor_name），
 {class_date：active_date，course_id：active_course，
 sponsor_name：active_sponsor}）。first.attributes）
 
＃渲染完成确认表单/表单
 flash [：success ] =为验证而保存的合格事件！ 
 respond_to do | format | 
 format.html {render'users / user_dashboard'} 
结束
 
其他
＃如果记录完成
 @ qualifying_event.save 
 flash [：success] =创建的资格赛事！ 
 redirect_to user_dashboard_path 
 end 
  

可能在'else'声明。我还没有添加代码来验证所有需要的信息是否存在等。

我可以保存并从数据库中检索信息，提交编辑的信息电话'get'而不是'post'。我错过了什么？

解决方案

删除< form class =form-inline> （以及结束标记，如果有的话）在 form_for 之前。 HTML表单不能嵌套，因此只处理具有 GET 方法的外部表单。

I have a long form that auto-fills with information from our database (based upon partial information supplied by a user). When the user verifies the information and re-submits the form, the information should be saved as the users. The form - qualifying_events - is a partial that's in the views / shared folder. The data that autofills it is rendered by the qualifying_events_controller as part of the create method. The partial is presented for verification in a views / users page that's rendered by the user controller. The initial, partial information input by a user - in a similar partial on the same page - is correctly saving. Here's the top of the form:

<form class="form-inline">
  <%= form_for(@qualifying_event) do |f| %>
  <%= render 'shared/error_messages', object: f.object %>
<div >   
  <div class="form-group col-sm-12 text-center" style="margin-bottom: 5px;"><h5>
    <div>
      <li style="list-style-type: none; float: left; display: none; visibility: hidden;">
      <%= current_user %>
      </li>
    </div>
    <div>
      <li style="list-style-type: none; float: left;">
      <%= f.label :class_date %><br/>
      <%= f.text_area :class_date, autofocus: true %>
      </li>
    </div> 

Here is the error message:

No route matches [GET] "/qualifying_events" 

Here's what I've tried:
1. Explicitly adding a route to the config / routes file although it already showed if I ran rake routes:

post 'qualifying_events_path'     =>  'qualifying_events#create'

2. Changing the form_for language to explicitly call 'post':

<%= form_for(@qualifying_event, url: qualifying_events_path, method: => post) do |f| %>

I still get the same error message. Since I have other forms that are saving to the database with the same code, I have to assume something changes when a form is populated from a database and one wants to re-save the information. I'm using the devise gem so I looked at the registration#edit code, hoping I could follow the format:

  <%= form_for(resource, as: resource_name, url: registration_path(resource_name), html: { method: :put }) do |f| %>

Unfortunately, that approach didn't work either.

For 'completeness', here's the qualifying_events_controller code:

def create 
  @user = current_user
  @qualifying_event = current_user.qualifying_events.build(qualifying_event_params) 

  if @qualifying_event.validated.nil?
  # Match partial course information from current_user with records in table

  # Get partial record's information
  active_date = @qualifying_event.class_date
  active_course = @qualifying_event.course_id
  active_sponsor = @qualifying_event.sponsor_name

  # Match on class_date, course_id, and sponsor_name
  @qualifying_event = QualifyingEvent.new
  @qualifying_event.assign_attributes(QualifyingEvent.
      where("(class_date = :class_date AND course_id = :course_id) 
      OR (class_date = :class_date AND sponsor_name = :sponsor_name) 
      OR (course_id = :course_id AND sponsor_name = :sponsor_name)",
      {class_date: active_date, course_id: active_course, 
          sponsor_name: active_sponsor}).first.attributes)

  # render to confirmation form / form for completion
  flash[:success] = "Qualifying Event saved for verification!"
  respond_to do |format|
    format.html  {render 'users/user_dashboard' }
  end

else
  # if the record is complete          
  @qualifying_event.save
  flash[:success] = "Qualifying Event created!"
  redirect_to user_dashboard_path
end 

There may be an error in the 'else' statement. I haven't yet added the code to verify that all the required information is present, etc.

I can save to and retrieve information from the database, however a re-submit of edited information calls 'get' rather than 'post.' What am I missing? Thank you in advance.

解决方案

Remove <form class="form-inline"> (and the closing tag if any) before form_for. HTML forms can't be nested, thus only the outer form are processed which is have GET method.
