djangochoices字段处理返回枚举值

1.代码model设计

class RoleInfo(models.Model):
choices=[('0','普通角色'),('1',"管理员")]
status_enum= [('0','禁用'),('1',"启用")]
role_name = models.CharField(max_length=50)
role_type = models.CharField(choices=choices,max_length=10)
status = models.CharField(choices=status_enum,max_length=10)
create_time = models.DateTimeField(auto_now_add=True)
update_time = models.DateTimeField(auto_now=True)
class Meta:
db_table = "tbl_role_info"
ordering = ["-create_time"]

2.serializer 设计：

class RoleSerializer(serializers.ModelSerializer):
role_type_value = serializers.SerializerMethodField()
status_value = serializers.SerializerMethodField()
def get_role_type_value(self,obj):
return obj.get_role_type_display()
def get_status_value(self,obj):
return obj.get_status_display()
class Meta:
model = models.RoleInfo
fields= ['id','role_name','role_type','role_type_value',
'status','status_value','create_time','update_time']
