模型类：
# 书籍信息模型
class BookInfo(models.Model):
btitle = models.CharField(max_length=20, verbose_name='名称') # 图书名称
bpub_date = models.DateField(verbose_name='发布日期') # 发布日期
bread = models.IntegerField(default=0, verbose_name='阅读量') # 阅读量
bcomment = models.IntegerField(default=0, verbose_name='评论量') # 评论量
isDelete = models.BooleanField(default=False, verbose_name='逻辑删除') # 逻辑删除
logo = models.ImageField(upload_to='booktest', verbose_name='图片', null=True)
def __str__(self):
return self.btitle
# 元类信息 : 修改表名
class Meta:
db_table = 'tb_books'
verbose_name = '图书'
verbose_name_plural = verbose_name
模型类序列化器：
class BookInfoModelSerializer(serializers.ModelSerializer):
class Meta:
model = BookInfo
fields = '__all__'
APIView视图：
from django.http import JsonResponse
from rest_framework.views import APIView
from rest_framework.response import Response
from .models import BookInfo, HeroInfo
from .serializers import BookInfoSerializer
# GET /books/
class BookListAPIView(APIView):
def get(self, request):
# 数据库查询
queryset = BookInfo.objects.all()
# todo:手动序列化操作，需要继承django中的view
# books_list = []
# for book in queryset:
# books_list.append({
# 'id': book.id,
# 'btitle': book.btitle,
# 'bpub_date': book.bpub_date,
# 'bread': book.bread,
# 'bcomment': book.bcomment,
# 'logo': book.logo
# })
# return JsonResponse(books_list)
# todo:使用序列化器
# 1.构建序列化器对象，进行序列化操作
serializer = BookInfoSerializer(queryset, many=True)
# 2.获取序列化数据
data = serializer.data
# 3. 返回
return Response(data=data)
