使用DRF实现五个api接口
2.1 新建app
django-admin startapp app01
2.2 配置环境
# 注册app01和rest_framework,由于drf提供了web调试界面，所以静态文件功能不能注释掉，不然web界面没有样式
INSTALLED_APPS = [
# 'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
# 'django.contrib.messages',
'django.contrib.staticfiles',
'app',
'app01',
'rest_framework',
]
2.3 视图
from app.models import *
from .serializer import studentSerializer
from rest_framework.viewsets import ModelViewSet
class studentModelViewset(ModelViewSet):
queryset = studentsInfo.objects.all()
serializer_class = studentSerializer
2.4 序列化器
app01/serializer.py:
from rest_framework import serializers
from app.models import *
class studentSerializer(serializers.ModelSerializer):
class Meta:
model = studentsInfo
fields = "__all__"
2.5 配置路由
app01/urls.py:
from rest_framework.routers import DefaultRouter
from . import views
router = DefaultRouter()
# 以后有几个视图集就注册几个
router.register("stu", views.studentModelViewset, basename="stu")
urlpatterns = [
] + router.urls
drfdemo1/urls.py:
from django.urls import path, include
urlpatterns = [
# path('admin/', admin.site.urls),
path('api/',include('app.urls')),
path('api/', include('app01.urls')),
]
2.6启动项目
python manage.py runserver 8000
