hi folks,
I am trying to create a custom form field, that is based on
MultipleChoicefield. it populates itself from database and displays a
nice multi-checkbox table for multiple photos selection for adding
them to article... I've run into problems when trying to process
'initial' inside __init__:
class PhotoChoiceField(MultipleChoiceField):
"""
Photo selection field, that populates itself
with photos from selected gallery on init
"""
widget = PhotoSelectWidget
def __init__(self, photosize, required=True, widget=None,
label=None,
initial=None, help_text=None, *args, **kwargs):
self.photosize = photosize
super(PhotoChoiceField, self).__init__(choices=(),
required=required,
widget=widget, label=label, initial=initial,
help_text=help_text,
*args, **kwargs)
...
self.gallery=Gallery.objects.get(pk=initial)
...
Form class has 'initial' attribute set:
class AttachForm(forms.Form):
sel_photos = PhotoChoiceField(label = _('Select photos from the
gallery'),
photosize = _('admin_thumbnail')
form = AttachForm(initial={sel_photos':request.GET.get('album')})
But it seems that i cannot get 'initial' set at Form level processed
at Field level. It is always None.
I need to pass some aadditional arguments to fields when creating form
instance, can somebody give me a hint on how to do that?
Fedor
