• test002文件下重要文件：

1.urls.py

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('drf_demo/',include('apps.drf_demo.urls'))
]

2.settings.py

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'apps.drf_demo',
    'rest_framework',
]

DATABASES = {
 'default': {
	# 数据库引擎（是mysql还是oracle等）
	'ENGINE': 'django.db.backends.mysql',
	# 数据库的名字
	'NAME': 'DjangoDB',
	# 连接mysql数据库的用户名
	'USER': 'root',
	# 连接mysql数据库的密码
	'PASSWORD': '123456',
	# mysql数据库的主机地址
	'HOST': '127.0.0.1',
	# mysql数据库的端口号
	'PORT': '3306',
  }
}

• apps.drf_demo文件下重要文件：

1.models.py

from django.db import models

# Create your models here.
class Person(models.Model):
    name = models.CharField(max_length=100,null=False)
    address = models.CharField(max_length=100,null=False)

2.serializers.py

from rest_framework import serializers
from .models import Person

class PersonSerializer(serializers.ModelSerializer):
    class Meta:
        model = Person
        fields= "__all__"
        # exclude = ['','',]

3.urls.py

from rest_framework.routers import DefaultRouter
from .views import PersonViewset

router = DefaultRouter()
router.register('person',PersonViewset,basename='person')


app_name = 'drf_demo'
urlpatterns = []+router.urls

4.views.py

from rest_framework import viewsets
from .models import Person
from .serializers import PersonSerializer

# 这个视图函数已经包含了增删改查操作
class PersonViewset(viewsets.ModelViewSet):
    queryset = Person.objects.all()
    serializer_class = PersonSerializer
