如何将 Model.viewset 中的查找字段更改为 Django Rest Framework 中的其他唯一参数？

Question

我在 django rest 框架中使用 Modelviewset。我想将查找字段更改为电子邮件（唯一）而不是 id。我曾尝试lookup_field = 'email'在我的 Schema 视图集中添加， 但它不起作用。这就是我得到的 { "detail": "Not found." } 如何解决这个问题。

我的 Views.py：

class SchemaViewSet(mixins.CreateModelMixin, mixins.ListModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet):

    queryset = models.Schema.objects.all()
    serializer_class = serializers.SchemaSerializer
    lookup_field = 'email'

我的模型.py：

class Schema(models.Model):
    """Database model for Schema """

    name= models.TextField()
    version = models.TextField()
    email = models.EmailField(unique = True )


    def __str__(self):
        return self.email

我的序列化程序.py：

class SchemaSerializer(serializers.ModelSerializer):
    """Serializes Schema"""

    class Meta:
        model = models.Schema
        fields = (  'id', 'name', 'version', 'email')

更新您的代码如下：

class SchemaSerializer(serializers.ModelSerializer):
"""Serializes Schema"""

class Meta:
    model = models.Schema
    fields = ("id", "email")
    lookup_field = "email"


class SchemaViewSet(viewsets.ModelViewSet):
    queryset = models.Schema.objects.all()
    serializer_class = serializers.SchemaSerializer
    lookup_field = "email"
    lookup_value_regex = "[^/]+"
