Django模型-用小写字母设置默认charfield [英] Django model - set default charfield in lowercase

问题描述

如何以小写字母设置默认字符字段？
这是我的模型：

How to set default charfield in lowercase? This is my model:

class User(models.Model):
    username = models.CharField(max_length=100, unique=True)
    password = models.CharField(max_length=64)
    name = models.CharField(max_length=200)
    phone = models.CharField(max_length=20)
    email = models.CharField(max_length=200)

    def __init__(self, *args, **kwargs):
        self.username = self.username.lower()

我尝试了 __ init __ 但它没有不行每次保存新记录时，我都希望使用小写形式的用户名。谢谢。

I tried the __init__ but it doesn't work. I want to make the username in lowercase every time new record saved. Thanks.

推荐答案

只需在save方法中进行即可。即，覆盖 Model 类的 save 方法。

Just do it in the save method. ie, override the save method of Model class.

def save(self, *args, **kwargs):
    self.username = self.username.lower()
    return super(User, self).save(*args, **kwargs)
