在​​app​​下创建​​fixtures​​目录，在里面创建​​mydata.json​​文件或者​​mydata.YAML​​格式文件（文件名没有强制规定），里面填写你要添加的数据，大致如下

[
  {
    "model": "card.WeekType",
    "pk": "1",
    "fields": {
      "week_day": "monday",
      "zh_hans": "周一"
    }
  },
  {
    "model": "card.WeekType",
    "pk": "2",
    "fields": {
      "week_day": "tuesday",
      "zh_hans": "周二"
    }
  }
]


调用： ​​python3 manage.py loaddata mydata​​

他会搜寻每个app下的​​fixtures​​目录中是否存在​​mydata​​的文件，存在即会加载里面的数据。

查看序列化器的信息

from apps.card.serializers.card_serializer import DiscountRuleSerializer
>>> a = DiscountRuleSerializer()
>>> print(repr(a))

    discount_factor = FloatField(label='优惠折扣系数', max_value=1.0, min_value=0.0, required=True)
