ruby – rails post params没有找到id

概述发布表单时收到以下错误：找不到没有ID的团队 我有以下帖子参数 {"utf8"=>"✓", "_method"=>"put", "authenticity_token"=>"knq4dG1U/5NJxMD6KYxfOpKd3CuOBHRlp6xCwdpwCnQ=", "match"=>{"name"=>"latest match", "date(1i)"=>"2013", "date(2 发布表单时收到以下错误：找不到没有ID的团队

我有以下帖子参数

{"utf8"=>"✓","_method"=>"put","authenticity_token"=>"knq4dG1U/5NJxMD6KYxfOpKd3CuOBHRlp6xCwdpwCnQ=","match"=>{"name"=>"latest match","date(1i)"=>"2013","date(2i)"=>"5","date(3i)"=>"19","teams_attributes"=>{"1368967240149"=>{"name"=>"Navi","ID"=>"1"}}},"commit"=>"Update Match","match_ID"=>"2"}

模型：

team has_many :matchipsteam has_many :matches :through => matchipsmatch has_many :matchipsmatch has_many :teams :through => matchips

团队控制器：

def create    @team = Team.find(params[:team_ID])  <-----fails here!    redirect_to @match  end

形成：

<%= nested_form_for @match,:url => {:action => "add_team_to_match_post"} do |f| %>  <% if @match.errors.any? %>    <div ID="error_explanation">      <h2><%= pluralize(@match.errors.count,"error") %> prohibited this match from being saved:</h2>      <ul>      <% @match.errors.full_messages.each do |msg| %>        <li><%= msg %></li>      <% end %>      </ul>    </div>  <% end %>  <div >    <%= f.label :name %><br />    <%= f.text_fIEld :name %>  </div>  <div >    <%= f.label :date %><br />    <%= f.date_select :date %>  </div>  <%= f.fIElds_for :teams,:HTML => { :class => 'form-vertical' } do |builder| %>  <%= builder.label "Team name:" %>    <%= builder.autocomplete_fIEld :name,autocomplete_team_name_teams_path,:update_elements => {:ID => "##{form_tag_ID(builder.object_name,:ID)}" },:class => "input-small",:placeholder => "Search" %>  <%= builder.hIDden_fIEld :ID %>  <% end %>  <%= f.link_to_add raw('<i ></i>'),:teams,:class => 'btn btn-small btn-primary' %>  </div>  <div >    <%= f.submit %>  </div><% end %>

所以我基本上在比赛和球队之间有多对多的关系.使用nested_form进行匹配,但问题是它在创建或更新之前正在寻找关联,我想要它.我以前使用多对一关联完成此 *** 作,其中子模型将在创建或更新父项时创建,在这种情况下我已经拥有所有我正在做的团队通过post / put请求传递ID和名称所以我可以将它与那场比赛联系起来.

如果有更好的方法来关联已创建的实体,请告诉我.

解决方法 你可能需要这样的东西：

def add_team_to_match_post    @match = Match.find(params[:match_ID])    params[:teams_attributes].each_value do |team_attributes|      team = Team.find(team_attributes[:ID])      @match.teams << team      team.matches << @match    end    redirect_to @matchend

基本上,这是遍历teams_attributes哈希中的每个团队并将其添加到匹配对象(因为这是多对多)
