Solution:
def clean(self):
if any(self.errors):
# Don't bother validating the formset unless each form is
valid on its own
return
for i in range(0, self.total_form_count()):
form = self.forms[i]
cleaned_data = form.clean()
display = cleaned_data.get('display', None)
if cleaned_data['DELETE'] == False:
if display.max_windows() >= display.windows:
raise forms.ValidationError("The display have all
windows occupied.")
Put the line if cleaned_data['DELETE'] == False: to check if the inline
have the attribute DELETE and if is false, to ignore deleted rows in
formset that have true in this attribute. =)
