hmm, this is getting funny ...
def _construct_forms(self):
# instantiate all the forms and put them in self.forms
self.forms = []
for i in xrange(self._total_form_count):
self.forms.append(self._construct_form(i))
print self.forms
def _construct_form(self, i, **kwargs):
"""
Instantiates and returns the i-th form instance in a formset.
"""
defaults = {'auto_id': self.auto_id, 'prefix':
self.add_prefix(i)}
if self.data or self.files:
defaults['data'] = self.data
defaults['files'] = self.files
if self.initial:
try:
defaults['initial'] = self.initial[i]
except IndexError:
pass
# Allow extra forms to be empty.
if i >= self._initial_form_count:
defaults['empty_permitted'] = True
defaults.update(kwargs)
form = self.form(**defaults)
self.add_fields(form, i)
print form
return form
as you can see, I´ve inserted print in _construct_form and
_construct_forms. the print-statement at the end of _construct_form
displays the form, but the print-statement in _construct_forms
displays: [None, None, None, None, None].
