models.py 模型层

from django.db import models
class Userinfo(models.Model):    
    gender_choices = (
    (1,'male'),
    (2,'female'),
    (3,'others')
    )
    # 将变量存在choice
    gender = models.IntegerField(choices=gender_choices)

​

tests.py 用来测试的文件

固定句式 数据对象.get_字段名_display() 当没有对应关系的时候 该句式获取到的还是数字

from django.test import TestCase  # 从test里面导入TestCase
# 从manage.py里面复制三个东西 配置默认环境变量
import os
import sys

if __name__ == "__main__":
    os.environ.setdefault("DJANGO_SETTINGS_MODULE", "day62.settings")
    # 配置
	import django
    django.setup()
    	
    
    from app01 import models
        user_obj = models.Userinfo.objects.filter(pk=4).first()
        print(user_obj.username)
        print(user_obj.gender)
    # 针对choices字段 如果你想要获取数字所对应的中文 你不能直接点字段
    
        print(user_obj.get_gender_display())

    record_choices = (('checked', "已签到"),
                  ('vacate', "请假"),
                  ('late', "迟到"),
                  ('noshow', "缺勤"),
                  ('leave_early', "早退"),
                  )
    record = models.CharField("上课纪录", choices=record_choices, default="checked", 

    score_choices = ((100, 'A+'),
                 (90, 'A'),
                 (85, 'B+'),
                 (80, 'B'),
                 (70, 'B-'),
