快速问题在这里。尝试搜索无济于事。主动模型串行器 - 自定义JSON响应
我正在努力为当前项目获得RESTful API。我发现Rails是这个目标的绝对宠儿,所以请检查另一个标记为rails的超棒!
但是我已经遇到了障碍,同时设计了/用户我目前的API响应这是一个本应返回用户对象的JSON数组的方法:
我的用户模型:
class User < ActiveRecord::Base
devise :database_authenticatable, :registerable, :recoverable, :rememberable, :trackable, :validatable
has_many :favorites
has_many :reservations
has_many :venues, through: :favorites
has_many :venues, through: :reservations
belongs_to :gender
belongs_to :city
belongs_to :role
has_one :avatar
has_many :payments
has_one :payment_history
has_many :promotion_claims
has_many :social_identifiers
end
我的路线:
Rails.application.routes.draw do
namespace :api, defaults: { format: :json } do
namespace :v1 do
devise_for :users
..........................
resources :roles
resources :genders
resources :cities
#Users method
get 'users', to: "users#index"
end
end
我的控制器:
class API::V1::UsersController < API::V1::ApplicationController
before_action :set_address, only: [:show, :edit, :update, :destroy]
# GET /users
# GET /users.json
def index
@users = User.all
render json: @users
end
end
个
我的串行:
class UserSerializer < ActiveModel::Serializer
attributes :id, :first_name, :last_name, :cellphone, :email, :birthday, :username
has_one :gender
has_one :city
has_one :role
end
class GenderSerializer < ActiveModel::Serializer
attributes :name
end
class CitySerializer < ActiveModel::Serializer
attributes :name
end
class RoleSerializer < ActiveModel::Serializer
attributes :name
end
以此为据达到一个相当令人满意的结果如我所得到的JSON响应:
// GET http://localhost:3000/api/v1/users
[
{
"id": 1,
"first_name": "Richmond",
"last_name": "Huels",
"cellphone": "29 8244 9100",
"email": "[email protected]",
"birthday": "2011-02-23T19:24:00.151Z",
"username": "alba.ortiz",
"gender": {
"name": "Male"
},
"city": {
"name": "San Pedro Garza García"
},
"role": {
"name": "admin"
}
},
不过,我想我的JSON响应要更多的东西像:
// 20160225162402
// GET http://localhost:3000/api/v1/users
[
{
"id": 1,
"first_name": "Richmond",
"last_name": "Huels",
"cellphone": "29 8244 9100",
"email": "[email protected]",
"birthday": "2011-02-23T19:24:00.151Z",
"username": "alba.ortiz",
"gender": "Male",
"city": "San Pedro Garza García",
"role": "rp"
},
我试着覆盖UserSerializer中的属性方法,并使它,所以我可以做任何我w蚂蚁与json哈希返回之前,但它没有工作:
#attributes override to get the right format for the response
def attributes
data = super
data[:city] = data[:city][:name]
data[:gender] = data[:gender][:name]
data[:role] = data[:city][:name]
data
end
有没有什么办法来实现我需要我的API?
谢谢红宝石主义者,你统治并保持惊人!
