【问题描述】:
我只是想知道 Rails 如何使用 JSON 中的 activemodel-serializer 渲染模型对象。 我安装了 activemodel-serializer,但输出有所不同。
理想是这样的:
"products": [
{
"id": 1,
"title": "Digital Portable System",
},
{
"id": 2,
"title": "Plasma TV",
}
]
我的代码很简单;
class Api::V1::ProductsController < ApplicationController
before_action :authenticate_with_token!, only: [:create, :update, :destroy]
respond_to :json
def index
respond_with Product.all
end
def show
respond_with Product.find(params[:id])
end
def create
product = current_user.products.build(product_params)
if product.save
render json: product, status: 201, location: [:api, product]
else
render json: { errors: product.errors }, status: 422
end
end
def update
product = current_user.products.find(params[:id])
if product.update(product_params)
render json: product, status: 200, location: [:api, product]
else
render json: { errors: product.errors }, status: 422
end
end
def destroy
product = current_user.products.find(params[:id])
product.destroy
head 204
end
private
def product_params
params.require(:product).permit(:title, :price, :published)
end
end
