标签：py models 创建 polls django api urls import drf

1.安装项目依赖

pip install django
pip install djangorestframework

　　

2.创建django项目

django-admin startproject mysite

　

3.创建app

python manage.py startapp polls

　　

4.创建model

from django.db import models


class Book(models.Model):
    name = models.CharField(max_length=200)
    author = models.CharField(max_length=20)
    pub_date = models.DateTimeField('date published')

　　

5.创建序列化类

from rest_framework import serializers

from polls.models import Book


class BookModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = Book
        fields = "__all__"

　　

　　

6.创建视图

 

from rest_framework.viewsets import ModelViewSet

from polls.models import Book
from polls.serializers import BookModelSerializer


class BookViewSet(ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookModelSerializer

　　

7.添加路由

polls/urls.py

from rest_framework.routers import DefaultRouter

from polls import views

router = DefaultRouter()
router.register("book", views.BookViewSet, basename="book")

urlpatterns = [

              ] + router.urls

mysite/mysqite/urls.py

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

urlpatterns = [
    path('admin/', admin.site.urls),
    path("polls/", include("polls.urls"))
]

8. 数据迁移

python manage.py makemigrate
python manage.py migrate

9.启动项目

python manage.py runserver
