How to get extra data in clean_data?

[李余通]

My mind is here:

class Register(forms.Form):
    passwd = forms.CharField(max_length=20,label='密码',widget=forms.PasswordInput)
    repasswd = forms.CharField(max_length=20,label='重复密码',widget=forms.PasswordInput)

def clean_passwd(self):
    passwd = self.cleaned_data['passwd']
    repasswd = self.cleaned_data['repasswd'] #here is error

    if passwd != repasswd:
        raise forms.ValidationError('两次密码不一致')
    return passwd

So,problems is i want to check passwd and repasswd same,How to solve?

As described in the docs on form and field validation, if you want to
validate one field using another field, you do so in the clean()
method:

https://docs.djangoproject.com/en/1.8/ref/forms/validation/

and in detail

https://docs.djangoproject.com/en/1.8/ref/forms/validation/#cleaning-and-validating-fields-that-depend-on-each-other

Cheers

You can see how Django itself validates the password:

Thanks very much!
So now hava two way to solve problems;
one is clean（）

def clean(self):
    cleaned_data = super(Register,self).clean()
    passwd = cleaned_data.get('passwd')
    repasswd = cleaned_data.get('repasswd')
    if(passwd != repasswd):
        self.add_error('repasswd',u'两次密码不一致')
another is clean_passwd():
def clean_passwd(self):
    passwd = self.cleaned_data.get('passwd')
    repasswd = self.cleaned_data.get('repasswd')

    if passwd != repasswd:
        raise forms.ValidationError('两次密码不一致')
    return passwd

change my code 
repasswd = self.cleaned_data['repasswd'] 
to
repasswd = self.cleaned_data.get('repasswd')

use claea()

def clean(self):
    cleaned_data = super(Register,self).clean()
    passwd = cleaned_data.get('passwd')
    repasswd = cleaned_data.get('repasswd')
    if(passwd != repasswd):
        self.add_error('repasswd',u'两次密码不一致')

Perhaps reading some simple documentation about HTML might be more
assistance than asking several thousand people to do it for you?
