主路由配置URL
导包
from django.contrib import admin
from django.urls import path,include
配置路由
urlpatterns = [
path('admin/', admin.site.urls),
path('app/',include('app.urls',namespace='app')),#app为子应用名字
]
子路由配置
from django.contrib import admin
from django.urls import path
from . import views
app_name = 'myapp'
urlpatterns = [
path('index/',views.Index.as_view(),name='index'),
path('register/',views.Register.as_view(),name='register'),
path('login/',views.Login.as_view(),name='login'),
path('details/',views.Details.as_view(),name='details'),
path('edit/',views.Edit.as_view(),name='edit'),
path('addgoods/',views.Addgood.as_view(),name='addgoods'),
]
admin.py设置
from django.contrib import admin
from . import models
# Register your models here.
admin.site.register(models.User)#user为表名
admin.site.register(models.Goods)#goods为表名
序列化配置
第一种
在app子应用路径下新建 myserializers.py
内容为：
from rest_framework import serializers
from . import models
class UserSerializers(serializers.ModelSerializer):
class Meta:
models = models.User
fields = '__all__'
#user,goods为表名
class GoodsSerializers(serializers.ModelSerializer):
class Meta:
model = models.Goods
fields = '__all__'
第二种
在views.py文件开头加上：
#商品表实例化
class Goodsser(serializers.Serializer):#实例化建表字段
id = serializers.IntegerField()
title = serializers.CharField(max_length=30)
price = serializers.DecimalField(max_digits=5,decimal_places=2)
img = serializers.ImageField()
# uid=Userser()
#用户实例化
class Userser(serializers.Serializer):
id = serializers.IntegerField(read_only=True)
name = serializers.CharField(max_length=30)
pwd = serializers.IntegerField()
goods_set=Goodsser(many=True)
#正向查找如果反向查找的话在上面用户实例化中添加Goods_set = Goodsser(many=Ture)且两个实例化位置要交换
