安装：
pip install djangorestframework
pip install markdown # Markdown support for the browsable API.
pip install django-filter # Filtering support
配置：
settings.py: INSTALLED_APPS = [ ... 'rest_framework',]
urls.py: url(r'^api-auth/', include('rest_framework.urls')) #django2 中 re_path(r'^api-auth/', include('rest_framework.urls'))
简单实验：
models.py
from django.db import models
# Create your models here.
class BaseModel(models.Model):
created_time = models.DateTimeField(auto_now_add=True,verbose_name='创建时间')
updated_time = models.DateTimeField(auto_now=True,verbose_name="修改时间")
class Meta:
abstract = True
class Brand(BaseModel):
name = models.CharField(max_length=20,verbose_name='品牌')
class Goods(BaseModel):
name = models.CharField(max_length=20,verbose_name='商品名字',null=True)
price = models.DecimalField(max_digits=7,decimal_places=2,default=0.00,verbose_name='价格')
brand = models.ForeignKey(Brand,on_delete=models.CASCADE)
class Meta:
db_table = 'goods_goods_details'
def __str__(self):
return self.name
serializers.py中：
from rest_framework import serializers

#外键也可以序列化
#brand = BrandSerializer()

def create(self, validated_data):
return Goods.objects.create(**validated_data)
urls.py中
from django.urls import re_path
from goods.views import GoodsView
urlpatterns = [
re_path(r'^/goods$',GoodsView.as_view(),name='goods'),
]
views.py中
from django.http import HttpResponse, JsonResponse
