我在查询集上使用get_or_create
时出错:
TypeError at ...
save()
得到了一个意外的关键字参数“使用”
这是我的看法:
class MailingListSubscriptionForm(forms.ModelForm):
"""Form for subscribing to a mailing list"""
# Notes : This form will not check the uniquess of
# the 'email' field, by defining it explictly and setting
# it the Meta.exclude list, for allowing registration
# to a mailing list even if the contact already exists.
# Then the contact is always added to the subscribers field
# of the mailing list because it will be cleaned with no
# double.
email = forms.EmailField(label=_('Email'), max_length=75)
def save(self, mailing_list):
data = self.cleaned_data
contact, created = Subscriber.objects.get_or_create(
email__exact=data['email'], defaults={'email': data['email']}
)
mailing_list.subscribers.add(contact)
mailing_list.unsubscribers.remove(contact)
class Meta:
model = Subscriber
fields = ('email',)
这是完整的追溯:
