Django Rest Framwork迭代模型序列化器中的字段 [英] django rest framwork iterate throug fields in model serializer

问题描述

我想遍历ModelSerializer中的字段，并希望使这些字段成为必填字段。这不起作用。我怎样才能做到这一点。

i want to iterate through the fields in ModelSerializer and want to make those field required . this not working . how can i do that. Somebody please help me.

class CustomerSerializer(serializers.ModelSerializer):

    class Meta:
        model = Customer

        fields = ("email", "phone_no", "full_name", "landline_no")

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)

        for field in self.fields:
            self.fields[field].required = True
            self.fields[field].allow_blank = False

推荐答案

您可以在MetaSerializer的Meta类中添加额外的args，例如：

You can add the extra args in Meta class for a ModelSerializer, like this:

class Meta:
    model = Customer

    fields = ("email", "phone_no", "full_name", "landline_no")
    extra_kwargs = {'email': {'required': True, 'allow_blank': False}}

如果所有字段都需要此字段，则应重新考虑字段中的字段客户模型。您可以添加 blank = False 和/或 null = False 。在创建ModelSerializer时，Rest框架会将这些信息考虑在内

If you need this for all the fields, then you should reconsider your fields inside the Customer model. You can add blank=False and/or null=False. Rest framework takes that information into consideration when creating a ModelSerializer
