Question

我有一个form_for，如下所示：

  <div class="modal-body">
    <%= form_for @folder, url: add_client_folders_path, html: { id: "add_client" }   do |f| %>
      <%= f.fields_for :client_profiles do |client_builder| %>
          <%= client_builder.select :id, @clients.collect {|client| [ client.name, client.id ] }, { include_blank: true }, {class: "form-control"} %>
      <% end %>
    <% end %>
  </div>
  <div class="modal-footer">
    <%= submit_tag "Add Client", class: "btn btn-primary", form: "add_client" %>
  </div>

提交表单时，params哈希看起来像这样：

参数：{＆＃34; utf8＆＃34; =＆gt;＆＃34;✓＆＃34;，＆＃34; authenticity_token＆＃34; =＆gt;＆＃34; 7qxjMI1H / + uMP4qZWwG4lHxdrBBM1z＆＃34;，＆＃34;夹＆＃34; =＆GT; {＆＃34; client_attributes＆＃34; =＆GT; {＆＃34; 0＆＃34; =＆GT; {＆＃34; ID＆＃34; =＆GT;＆＃34 ; 25＆＃34;}}}，＆＃34;提交＆＃34; =＆gt;＆＃34;添加客户＆＃34;，＆＃34; id＆＃34; =＆gt;＆＃34; add_client＆＃34;}

它给出了以下错误：

Couldn't find Folder with 'id'=add_client

为什么Rails在哈希中提交html id属性会导致此错误？

即使我删除了ID，它仍然会给我这个错误。路线看起来像这样：

  resources :folders do
    post :add_client, on: :collection
  end

当我明确声明post方法时，它提交正常：

method: :post

但为什么我必须在这里指定方法帖？

对于未来的读者，我比创建单独的资源路径更好。您可以继续重用更新的restful资源，因为更新现有记录时将自动保存新关联：

 <%= form_for @folder do |f| %>
   <%= f.fields_for :client_profiles, f.object.client_profiles.build do |client_builder| %>
     <%= client_builder.select :id, @clients.collect {|client| [ client.full_name, client.id ] }, { include_blank: true }, {class: "form-control"} %>
      <%= f.submit "Add Client", class: "btn btn-primary" %

rails设置form_for id属性原因：找不到'id'= add_client的文件夹
