Rails，返回current_user爲賣方的所有Items的API端點？

我需要設置一個API終點，它將返回current_user爲賣家的所有項目。我盡我所能去建立REST風格的路線所以對我有這樣的：Rails，返回current_user爲賣方的所有Items的API端點？

的routes.rb

Rails.application.routes.draw do 
    resources :users 
    resources :items 
    get "users/:id/items" => "users#items" 
...

users_controller.rb

這將返回所有項目，其中seller_id列等於PARAMS [：ID]。最後，我希望爲items表添加buyer_id列，並且能夠過濾出來 - 所以我需要區分買方和賣方。很明顯，我在這裏沒有這樣做。

class UsersController < ApplicationController 

    def seller_items 
     User.find(params[:id]).items 
    end 
end

item.rb的

class Item < ActiveRecord::Base 
    belongs_to :seller, :class_name => 'User', :foreign_key => 'seller_id' 
    enum status: {available: 0, pending: 1, sold: 2, expired: 3, banned: 4 } 
end

user.rb

class User < ActiveRecord::Base 
    has_many :items, :class_name => 'Item', :foreign_key => 'seller_id' 
end

schema.rb

ActiveRecord::Schema.define(version: 20160715043217) do 

    # These are extensions that must be enabled in order to support this database 
    enable_extension "plpgsql" 

    create_table "categories", force: :cascade do |t| 
    t.string "title" 
    t.datetime "created_at", null: false 
    t.datetime "updated_at", null: false 
    end 

    create_table "items", force: :cascade do |t| 
    t.string "title" 
    t.text  "description" 
    t.integer "price",   limit: 8 
    t.integer "status" 
    t.datetime "published_date" 
    t.datetime "created_at",    null: false 
    t.datetime "updated_at",    null: false 
    t.integer "seller_id" 
    end 

    add_index "items", ["seller_id"], name: "index_items_on_seller_id", using: :btree 

    create_table "users", force: :cascade do |t| 
    t.string "name" 
    t.decimal "latitude", precision: 9, scale: 6 
    t.decimal "longtitude", precision: 9, scale: 6 
    t.datetime "created_at",       null: false 
    t.datetime "updated_at",       null: false 
    end 

    add_foreign_key "items", "users", column: "seller_id" 
end

你想_buyer_，並且向我們展示_seller_不工作。我現在很困惑:)問題是什麼？ –

那麼，有沒有真正的問題？ –

我覺得他很疑惑如何根據他所做的銷售物品添加購買物品 –

我將不得不針對每個

單獨的控制器個

的routes.rb

get "users/:id/sold_items" => "sold_items#index" 
get "users/:id/bought_items" => "bought_items#index"

控制器

class SoldItemsController 
    def index 
    User.find(params[:id]).sold_items 
    end 
end 

class BoughtItemsController 
    def index 
    User.find(params[:id]).bought_items 
    end 
end

車型

class User < ActiveRecord::Base 
    has_many :sold_items, :class_name => 'Item', :foreign_key => 'seller_id' 
    has_many :bought_items, :class_name => 'Item', :foreign_key => 'buyer_id' 
end 

class Item < ActiveRecord::Base 
    belongs_to :seller, :class_name => 'User', :foreign_key => 'seller_id' 
    belongs_to :buyer, :class_name => 'User', :foreign_key => 'buyer_id' 
    enum status: {available: 0, pending: 1, sold: 2, expired: 3, banned: 4 } 
end
