Django newbie here.
I wrote simplified login form which takes email and password. It works great if both email and password are supplied, but if either is missing i get KeyError exception. According to django documentation this should never happen:
By default, each Field class assumes the value is required, so if you pass an empty value -- either None or the empty string ("") -- then clean() will raise a ValidationError exception
I tried to write my own validators for fields (clean_email and clean_password), but it doesn't work (ie I get KeyError exception). What am I doing wrong?
class LoginForm(forms.Form):
email = forms.EmailField(label=_(u'Your email'))
password = forms.CharField(widget=forms.PasswordInput, label=_(u'Password'))
def clean_email(self):
data = self.cleaned_data['email']
if not data:
raise forms.ValidationError(_("Please enter email"))
return data
def clean_password(self):
data = self.cleaned_data['password']
if not data:
raise forms.ValidationError(_("Please enter your password"))
return data
def clean(self):
try:
username = User.objects.get(email__iexact=self.cleaned_data['email']).username
except User.DoesNotExist:
raise forms.ValidationError(_("No such email registered"))
password = self.cleaned_data['password']
self.user = auth.authenticate(username=username, password=password)
if self.user is None or not self.user.is_active:
raise forms.ValidationError(_("Email or password is incorrect"))
return self.cleaned_data
