django-枚举类型扩展方法

原文地址:https://docs.djangoproject.com/en/dev/ref/models/instances/#django.db.models.Model.get_FOO_display

关于django中枚举类型转换显示问题,每次设置枚举类型,

EXPERIENCE_CHOICES = (
  (1, '应届毕业生'),
  (2, '3年及以下'),
  ...
)
education = models.SmallIntegerField(choices=EDUCATION_CHOICES, default='不要求', verbose_name="学历要求")

数据库实际存储值为,1,2,3, 4, 5,序列化返回数据类型:

[
  {
    "id": 2,
    "name": "Python开发工程师",
    "salary": 3,
    "experience": 2,
    "education": 2,
    "type": 1,
    "create_time": "2018-12-11T10:48:03.076841+08:00",
      }
    }
  },
...
]

 如果想要在序列化返回时显示对应的字符串信息,只需要在序列化器中声明字段时指定source来源

class LatestJobSerializer(serializers.ModelSerializer):
    salary = serializers.CharField(source='get_salary_display')
    experience = serializers.CharField(source='get_experience_display')
    education = serializers.CharField(source='get_education_display')
    type = serializers.CharField(source='get_type_display')

    class Meta:
        model = Job
        fields = ['id', 'name', 'salary', 'experience', 'education', 'type', 'create_time', 'enterprise', 'locations', 'url']
