ROR：嵌套资源：NoMethodError

Question

在我的应用程序中，创建团队是为了解决挑战。创建团队后，成员可以加入该团队。

在创建挑战 -> 团队时一切正常，但在添加团队成员时，我收到此错误：

错误

Team_members 中的 NoMethodError#new

显示 /home/vincent/solvabl/app/views/team_members/_form.html.erb 提出第 1 行的位置：

undefined method `team_team_members_path' for #<#<Class:0x9bdadcc>:0xa179df0>

提取的源代码（第 1 行附近）：

1: <%= form_for([@challenge,@team,@team_member]) do |f| %>
2:   <% if @team_member.errors.any? %>
3:     <div id="error_explanation">
4:       <h2><%= pluralize(@team_member.errors.count, "error") %> prohibited this team_member from being saved:</h2>

模板包含的痕迹：app/views/team_members/new.html.erb

<%= form_for([@team,@team_member]) do |f| %>

    <div id="error_explanation">
      <h2><%= pluralize(@team_member.errors.count, "error") %> prohibited this team_member from being saved:</h2>

      <ul>
      <% @team_member.errors.full_messages.each do |msg| %>
        <li><%= msg %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

  <div class="field">

    <%= f.number_field :team_id %>
  </div>
  <div class="field">
    <%= f.label :user_id %><br />
    <%= f.number_field :user_id %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

非常感谢任何帮助！

Answer 1

你拥有的路线会给你challenges_team_team_members_path。为了获得team_team_members_path，请将以下内容添加到您的config/routes.rb：

resources :teams do 
  resources :team_members
end

更新：

请注意，此添加应该是对您已经定义的内容的补充。因此，您的 routes.rb 将具有：

resources :challenges do
  resources :teams do
    resources :team_members
  end
end

resources :teams do 
  resources :team_members
end
