一、构建表单，在这里我们先构建五个表单，分别是 author book publish user token 后面将会一一用到，如下：

models.py

from django.db import models

# Create your models here.

class User(models.Model):
    username = models.CharField(max_length=32)
    password = models.CharField(max_length=32)
    type_choice = ((1,"普通用户"),(2,"VIP"),(4,"SVIP"))
    user_type = models.IntegerField(choices=type_choice, default=1)

    def __str__(self):
        return self.username


class Token(models.Model):
    user = models.OneToOneField("User")
    token = models.CharField(max_length=128)

    def __str__(self):
        return self.token


class Author(models.Model):
    name = models.CharField(max_length=16)
    age = models.CharField(max_length=16)

    def __str__(self):
        return self.name


class Publish(models.Model):
    title = models.CharField(max_length=32)
    email = models.EmailField()

    def __str__(self):
        return self.title


class Book(models.Model):
    title = models.CharField(max_length=64)
    price = models.IntegerField()
    authors = models.ForeignKey(to="Author")
    publish = models.ForeignKey(to="Publish")

    def __str__(self):
        return self.title

二、对admin组件进行注册，利用admin来录入数据

admin.py

from django.contrib import admin
from app01.models import *
# Register your models here.

admin.site.register(Book)
admin.site.register(Author)
admin.site.register(Publish)
admin.site.register(User)

三、rest-framework的用法：

1、首先得写好序列化组件:在app01的根目录下面创建一个serializer.py 用来存放每一个组的序列化组件，组件如下：

from rest_framework import serializers
from app01.models import *


class PublishModelSerializers(serializers.ModelSerializer):
    class Meta:
        model = Publish
        fields = "__all__"


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


class AuthorModelSerializers(serializers.ModelSerializer):
    class Meta:
        model = Author
        fields = "__all__"

2、写好序列化组件之后就可以操作视图Views.py 了，操作如下：

from rest_framework import viewsets
from app01.models import *
from app01.serializer import *
# Create your views here.


class AuthorModelView(viewsets.ModelViewSet):
    queryset = Author.objects.all()
    serializer_class = AuthorModelSerializers


class BookModelView(viewsets.ModelViewSet):
    queryset = Book.objects.all()
    serializer_class = BookModelSerializers


class PublishModelView(viewsets.ModelViewSet):
    queryset = Publish.objects.all()
    serializer_class = PublishModelSerializers

3、写完了视图后就可以开始写最主要的url部分了！

from django.conf.urls import url,include
from django.contrib import admin
from rest_framework import routers
from app01 import views

router = routers.DefaultRouter()
router.register("author",views.AuthorModelView)



urlpatterns = [
    url(r'^admin/', admin.site.urls),

    url(r'', include(router.urls))

]

4、好了，这里就只需要在 Postman 里面输入url了，大功告成！
