使用DRF实现五个api接口

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
