Issue
I have form with one input for email and two submit buttons to subscribe and unsubscribe from newsletter:
<form action="" method="post">
{{ form_newsletter }}
<input type="submit" name="newsletter_sub" value="Subscribe" />
<input type="submit" name="newsletter_unsub" value="Unsubscribe" />
</form>
I have also class form:
class NewsletterForm(forms.ModelForm):
class Meta:
model = Newsletter
fields = ('email',)
I must write my own clean_email method and I need to know by which button was form submited. But the value of submit buttons aren't in self.cleaned_data
dictionary.
Could I get values of buttons otherwise?
Solution
You can use self.data
in the clean_email
method to access the POST data before validation. It should contain a key called newsletter_sub
or newsletter_unsub
depending on which button was pressed.
# in the context of a django.forms form
def clean(self):
if 'newsletter_sub' in self.data:
# do subscribe
elif 'newsletter_unsub' in self.data:
# do unsubscribe
