1. 安装:

pip install djangorestframework

2. 添加`'rest_framework'`到您的`INSTALLED_APPS`设置。

settings.py


INSTALLED_APPS = [
    ...
    'rest_framework',
]

3. 定义模型

models.py



from django.db import models


class BookModel(models.Model):
    name = models.CharField(max_length=64)
    # 最长6位  小数点后保留两位
    price = models.DecimalField(max_digits=6, decimal_places=2)
    author = models.CharField(max_length=32)
    publish = models.CharField(max_length=32)
    # 修改时间
    update_time = models.DateTimeField(auto_now=True)
    # 第一次时间
    first_create_time = models.DateTimeField(auto_now_add=True)

    class Meta:
        verbose_name = "图书表"

    def __str__(self):
        return self.name

    def __repr__(self):
        return self.__str__()

4. 定义 serializers

serializers.py



from rest_framework.serializers import ModelSerializer
from .models import BookModel


class BookModelSerializer(ModelSerializer):
    class Meta:
        model = BookModel
        fields = '__all__'

5. 视图

views.py



from rest_framework.viewsets import ModelViewSet
from .models import BookModel
from .serializers import BookModelSerializer


class BookModelViewSet(ModelViewSet):
    queryset = BookModel.objects.all()
    serializer_class = BookModelSerializer
