django中model的choices字段

model.py:

class User(models.Model):

    id = models.UUIDField(primary_key=True, auto_created=True, default=uuid.uuid4, editable=False)

    user = models.CharField(max_length=20)

    password = models.CharField(max_length=50)

    name = models.CharField(max_length=10)

    headImage = models.CharField(max_length=30)

    GENDER_CHOICES = (

        (u'M', u'Male'),

        (u'F', u'Female'),

    )

    gender = models.CharField(max_length=2, choices=GENDER_CHOICES, default='M')

保存后查看：

response3 = User.objects.get(id='443f872fab1c485da76f78a79ab316f5')
print(response3.gender)
print(response3.get_gender_display())

打印结果：
