show_members アクションにリンクしようとすると、奇妙なエラーが発生します 

Routing Error
No route matches "/groups/1/show_members"

#routes.rb
get 'groups/:id/members' => 'groups#show_members'

#groups_controller.rb
def show_members

rake routes を実行すると、次のようになります。

#rake routes
            groups GET    /groups(.:format)           {:controller=>"groups", :action=>"index"}
            groups POST   /groups(.:format)           {:controller=>"groups", :action=>"create"}
         new_group GET    /groups/new(.:format)       {:controller=>"groups", :action=>"new"}
        edit_group GET    /groups/:id/edit(.:format)  {:controller=>"groups", :action=>"edit"}
             group GET    /groups/:id(.:format)       {:controller=>"groups", :action=>"show"}
             group PUT    /groups/:id(.:format)       {:controller=>"groups", :action=>"update"}
             group DELETE /groups/:id(.:format)       {:controller=>"groups", :action=>"destroy"}
        group_join GET    /groups/join(.:format)       {:controller=>"groups", :action=>"join"}
 group_remove_user PUT    /groups/remove_user(.:format){:controller=>"groups", :action=>"remove_user"}
                   GET    /groups/:id/members(.:format){:controller=>"groups", :action=>"show_members"}

更新: しかし、show_members アクションで実行したいのは、そのグループ内のすべてのユーザーを表示することだけです。ユーザーの機能とパスを同じままにしたい。show_members アクションは、show と同じように group にルーティングされます。私のグループ コントローラーでは、デフォルトのグループ表示アクションを 3 つのページに分割しました。私はそれに到達します。

#groups_controller.rb
def show_members
  @group = Group.find(params[:id])
  @members = @group.users
  @group_admin = User.find(@group.group_admin)
  respond_to do |format|
    format.html # show.html.erb
    format.xml  { render :xml => @group }
  end
end

一致するルートがないという場合、Rails は正しいです。(" "なしで) のようなルートを作成してい/groups/1/show_membersます。routes.rb/groups/1/membersshow_

routes.rb次のように変更する必要があります。

get 'groups/:id/show_members` => 'groups#show_members'

もちろん問題は、すべてが正しく行われていないことです。

resources :groups do |group|
  group.resources :members
end

link_to @member.name, [@group, @member]

魔法。

今ガイドを読むことは非常に良い考えでしょう。
