Main routing configuration URL
Guide package
from django.contrib import admin
from django.urls import path,include
Configuring Routing
= the urlpatterns [
path ( 'ADMIN /', admin.site.urls),
path ( 'App /', the include ( 'app.urls', namespace = 'App')), for the sub-application App # Name
]
Sub routing configuration
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('details/',views.Details.as_view(),name='details'),
path('edit/',views.Edit.as_view(),name='edit'),
path('addgoods/',views.Addgood.as_view(),name='addgoods'),
]
Set admin.py
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
Serialization configuration
The first
New app myserializers.py at the sub-application path
Says:
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__'
The second
At the beginning of views.py file with:
# Product Table instantiated
class Goodsser (serializers.Serializer): # instantiated Field built
ID = serializers.IntegerField ()
title = serializers.CharField (MAX_LENGTH = 30)
. Price = serializers.DecimalField (max_digits =. 5, decimal_places = 2)
= serializers.ImageField IMG ()
# Userser UID = () # instantiated user class Userser (serializers.Serializer): ID = serializers.IntegerField (READ_ONLY = True) name = serializers.CharField (MAX_LENGTH = 30) pwd = serializers .IntegerField () goods_set = Goodsser (MANY = True) # forward lookup reverse lookup if it is added Goods_set = Goodsser (many = Ture) and two instances of the above positions to be exchanged user instantiation
