drf后台数据校验以及认证组件

校验

# objson.py
class BookJson(serializers.ModelSerializer):
    class Meta:
        model = models.Book
        fields = '__all__'
    


    # 单个字段校验
    name = serializers.CharField(min_length=3, max_length=5, error_messages={'min_length': '太短'})
    # 局部钩子校验
    def validate_name(self, value):
        from rest_framework.exceptions import ValidationError
        if 'sb' in value:
            raise ValidationError('不能出现哔词汇')
        return value

# views.py
class Books(APIView):
    # 新增
    def post(self, request):
        book = request.data
        book_json = objson.BookJson(data=book)  # 必须明确data
        if book_json.is_valid():  # 校验
            book_json.save()  # 保存
            return Response({
                'status': 0,
                'msg': 'ok',
                'results': book_json.data
            })
        return Response({
            'status': 1,
            'msg': book_json.errors,
        })

了解

# 全局钩子校验
def validate(self, attrs):
    from rest_framework.exceptions import ValidationError
    pwd = attrs.get('pwd')
    re_pwd = attrs.get('re_pwd')
    if pwd == re_pwd:
        return attrs
    else:
        raise ValidationError('密码校验失败')

认证、频率

# views.py

class Auth:
    def authenticate(self, request):
        # 完成具体认证功能
        pass

class Book(APIView):
    authentication_classes = [Auth, ]
