Django rest methodfield如果条件工作问题？

Question

我想在序列化器中传递全部和部分付费的用户，但未显示 ，

payment_status = serializers.SerializerMethodField()

def get_payment_status(self, obj):
    if int(obj.total_due) > 0:
        paid_status ={'payment_status':'Partially paid'}
    else:
        paid_status={'payment_status':'Completely paid'}
    return paid_status

Answer 1

尝试返回字符串，而不是字典

payment_status = serializers.SerializerMethodField()

def get_payment_status(self, obj):
    if int(obj.total_due) > 0:
        return 'Partially paid'
    return 'Completely paid'
