ROR：嵌套資源：NoMethodError

Question

在我的應用程序中，創建團隊是爲了解決挑戰。團隊創建後，成員可以加入該團隊。創建挑戰時

一切正常 - >球隊，但是當談到加入團隊成員那就是當我收到此錯誤：

錯誤

NoMethodError在Team_members＃新

顯示/home/vincent/solvabl/app/views/team_members/_form.html.erb其中線＃1提出：

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

提取的源（左右線＃1）：

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>

你有的路線會給你challenges_team_team_members_path。爲了得到team_team_members_path以下內容添加到您的config/routes.rb：

resources :teams do 
    resources :team_members 
end 

更新：

請注意，這除了應該是除了你已經定義了什麼。所以，你的routes.rb將有：

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

resources :teams do 
    resources :team_members 
end
