Question

I have an ostensibly simple problem. Here is my models.py:

from django.db import models

class Email(models.Model):
    def __unicode__(self):
       return self.email
    email = models.EmailField()

EmailField, according to the docs, should check if the entered email address is valid. So then why does my shell allow me to save malformed emails? In the shell:

>>> from emailapp.models import Email
>>> e = Email(email="sdf")
>>> e
<Email: sdf>
>>> e.save()
>>> Email.objects.all()
[<Email: [email protected]>, <Email: [email protected]>, <Email: sdf>]

The admin interface doesn t allow me to save these malformed emails, but the shell does.Why is this?

Answer 1

文件明确显示,,必须称呼核证。

一些外地有效人员只能以表格形式(django admin使用表格)。在这种情形下,<代码>Email Field刚刚被翻译成Char Field(输入数据库),因此,你没有从空壳中发现任何错误。

我认为,之所以这样做,是因为制定模型并非非常常见。如果你仍然希望从任何地方确认正确的电子邮件,我建议你超越<代码>save(方法:

from django.core.validators import email_re
from django.core.exceptions import ValidationError

def save(self, *args, **kwargs):
    if not email_re.match(self.email):
        raise  ValidationError(u %s is not a correct email  % self.email)
    super(Email, self).save(*args, **kwargs)

除重写“储蓄(储蓄)”方法外,进行模型验证的另一个方式是使用Django s pre_save sign 。你们可以制造一种先天信号。 h可以称作“全部”方法,该方法将进行模型验证。
