Question

我正在尝试通过forms.py对电子邮件进行验证，但它给了我一个错误＃34;太多的值无法解压缩＆＃34;虽然我是django和python编程的新手。

这是我的代码：

  <div class="intro-custom">

Answer 1

尝试这样的事情

    extension = provider[::-1].split('.')[0]
    # if not domain == 'USC':
    #   raise forms.ValidationError("Please make sure you use your USC email.")
    if not extension == "ude":
        raise forms.ValidationError("Please use a valid .EDU email address")
    return email

Answer 2

异常ValueError: too many values to unpack是由于根据大小将列表解压缩到不匹配的目标变量而引起的。例如，

>>> a, b, c = 'xxx.yyy.edu'.split('.')      # ['xxx', 'yyy', 'edu']

# too few target variables
>>> a, b = 'xxx.yyy.edu'.split('.')         
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: too many values to unpack

# too many target variables
>>> a, b, c, d = 'xxx.yyy.edu'.split('.')   
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: need more than 3 values to unpack

在你的情况下，试试这个，

email = 'usrname@xxx.yyy.edu'
email_base, provider = email.split("@")
if 'edu' in provider.split('.'):
    return email
else:
    raise forms.ValidationError("Please use a valid .EDU email address")

值错误：解压缩，电子邮件验证的值太多
