Question

所以我遇到一个问题，我有这个应该返回json的索引操作，但在浏览器中我总是得到一个null响应。

控制器

class Admin::Groups::UsersController < Admin::GroupsController
  def index
    @user_groups = Group.includes(:group_type, :users).where("group_types.group_type_name = ?", 'Users').order("groups.group_name ASC")

    render json: @user_groups.to_json(:include => [:group_type, :users], :methods => :enabled)
  end

  def show
    @user_group = Group.includes(:group_type, :users).where("group_types.group_type_name = ?", 'Users').find_by_id(params[:id])

    render json: @user_group.to_json(:include => [:group_type, :users], :methods => :enabled)
  end
end

路线档案

namespace :admin do
  namespace :groups do
    resources :users, only: [:index, :show] do
      get 'enabled', :on => :collection
      get 'disabled', :on => :collection
    end
  end
end

佣金路线的输出

admin_groups_users GET    /admin/groups/users(.:format)                   admin/groups/users#index

真正让我失望的是，当我在rails控制台中运行索引操作中的相同代码时，它正在输出我期望的内容。 show动作也很好。仅仅为了测试，我添加了一个我刚刚调用index2的新路由，并将index操作中的代码复制+粘贴到index2中，并在浏览器中获得了正确的输出。 / p>

所以它必须与我的路线有关，但我不确定它是什么？

Answer 1

您需要沿着路线列表进一步移动此路线。

admin_group GET    /admin/groups/:id(.:format)                     admin/groups#show

按顺序搜索路线列表。 /admin/groups/users匹配此路线，:id等于users。

Answer 2

render的格式为

render :json => @user_groups

在其中为您调用to_json并且它无法传递参数，或者您可以执行此操作：

format.json { render @user_groups.to_json(:include => [:group_type, :users], :methods => :enabled) }

如果总是想要返回json，无论format是什么，那么只需摆脱json:的事情：

render @user_groups.to_json(:include => [:group_type, :users], :methods => :enabled)

Answer 3

请更改您的路线并检查

namespace :admin do
        namespace :groups do
          resources :users, :only => [:index,:show],:collection => {:enabled => :get,:disabled => :get}
        end
      end

Rails索引操作始终返回null
