如何從深度嵌套資源

Question

我深深嵌套的資源下面的相關數據：

resources :venues, shallow: true do 
     #Halls 
     get "hall/:id/exhibition" => "halls#exhibition", as: :exhibition 
     get "hall/:id/visit" => "halls#visit", as: :hall_visit 
     get "structure", :to => "venues#venue_structure" 
     resources :asset_types, :booths_tags, :tags, :uploaded_files, :events, :chats 
     resources :halls do 
      resources :webcasts 
      resources :booths do 
       resources :chats 
      end 
     end 
    end 

我想用檢索屬於特定用戶的所有events行activerecord

下面我試過，但這個似乎沒有被產生，我想其結果是事件數據：

def all_events 
    @events = User.joins(:venues => [:events]).where("venues.user_id" => current_user.id).select("events.*, users.*") 
    render json: @events 
    end 

上述生成：

{ 
users: [ 
{ 
id: 1, 
email: "eeee", 
title: "Mr", 
first_name: "aaaa", 
last_name: "cccc", 
position: "Web Developer", 
work_phone: "123456", 
company: "aaasszz", 
sign_in_count: 60, 
last_sign_in_ip: "127.0.0.1", 
confirmed_at: "2013-10-29T12:26:00.583+11:00", 
created_at: "2013-10-29T12:23:25.453+11:00", 
roles: [ 
3 
] 
}, 
{ 
id: 1, 
email: "email", 
title: "Mr", 
first_name: "aaa", 
last_name: "bbb", 
position: "Web Developer", 
work_phone: "123456", 
company: "sss", 
sign_in_count: 60, 
last_sign_in_ip: "127.0.0.1", 
confirmed_at: "2013-10-29T12:26:00.583+11:00", 
created_at: "2013-10-29T12:23:25.453+11:00", 
roles: [ 
3 
] 
} 
] 
} 

我想在JSON而非事件數據...

我還使用主動型串行。

這個問題的最佳方法是什麼？

事件模型：

class Event < ActiveRecord::Base 
    resourcify 
    belongs_to :venue 

    validates :name, :start, :finish, presence: true 

    has_one :event_image, ->{where(:image_type => UploadedFile::IMAGE_TYPE_EVENT_IMAGE)}, as: :imageable, class_name: 'UploadedFile', dependent: :destroy 
    has_one :logo1, ->{where(:image_type => UploadedFile::IMAGE_TYPE_EVENT_LOGO1)}, as: :imageable, class_name: 'UploadedFile', dependent: :destroy 
    has_one :logo2, ->{where(:image_type => UploadedFile::IMAGE_TYPE_EVENT_LOGO2)}, as: :imageable, class_name: 'UploadedFile', dependent: :destroy 
    accepts_nested_attributes_for :event_image, :logo1, :logo2, :reject_if => proc { |attributes| attributes['assets'].blank? } 

end 

Answer 1

的路由是不是從數據庫中的記錄檢索重要。唯一重要的是模型。您可以使用the includes method from ActiveRecord包含相關對象。因爲最後需要事件，所以只需從Event模型啓動查詢即可。這是我能想到的最簡單的辦法：

Event.includes(:venue).where(:venues => {:user_id => current_user.id}) 

，如果你不需要場地數據，只需使用joins：

Event.joins(:venue).where(:venues => {:user_id => current_user.id})
