Question

在我的应用程序中，创建团队来解决挑战。一旦团队成立，成员就可以加入该团队。

创建挑战时一切正常 - ＆gt;团队，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，其中第1行被提出：

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

提取的来源（第1行）：

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>

    @team_member.team_id = @team.id

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

  <div class="field">
    <%= f.label :team_id %><br />
    <%= 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！

您拥有的路线将为您challenges_team_team_members_path。为了team_team_members_path，请将以下内容添加到config/routes.rb：

resources :teams do 
  resources :team_members
end

更新：

请注意，此添加内容应与您已定义的内容相加。因此，您的routes.rb会：

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

resources :teams do 
  resources :team_members
end

ROR：嵌套资源：NoMethodError
