我使用Django Forms的唯一理由是输入的电子邮件字段.

是否有任何功能来检查是否有东西email或我必须使用它EmailField来检查和验证它​​？

Answer 1

您可以使用以下内容

from django.core.validators import validate_email
from django import forms

...
if request.method == "POST":
    try:
        validate_email(request.POST.get("email", ""))
    except forms.ValidationError:
        ...

假设你<input type="text" name="email" />的表格中有一个

Answer 2

您可以使用django.core.validators中的validate_email()方法:

>>> from django.core import validators
>>> validators.validate_email('test@example.com')
>>> validators.validate_email('test@examplecom')
Traceback (most recent call last):
   File "<console>", line 1, in <module>
   File "/Users/jasper/Sites/iaid/env/lib/python2.7/site-    packages/django/core/validators.py", line 155, in __call__
    super(EmailValidator, self).__call__(u'@'.join(parts))
  File "/Users/jasper/Sites/iaid/env/lib/python2.7/site-packages/django/core/validators.py", line 44, in __call__
    raise ValidationError(self.message, code=self.code)
ValidationError: [u'Enter a valid e-mail address.']
