for the last couple of hours, I´ve read all entries about custom
manipulators but I´m still not able to get my stuff working.
I probably just don´t see what´s wrong anymore:
this is part of my MODEL:
class UserProfile(models.Model):
music = models.ManyToManyField(Music, blank=True, null=True,
related_name="music")
....
this is part of my CUSTOM MANIPULATOR:
class UserprofileManipulator(forms.Manipulator):
def __init__(self):
MUSIC_CHOICES = [(str(c.id), str(c)) for c in
Music.objects.all()]
self.fields = (
forms.CheckboxSelectMultipleField(field_name="music",
choices=MUSIC_CHOICES),
...
)
def save(self, data):
temp = UserProfile(
...
)
temp.set_gadgets(data['gadgets'])
temp.save()
#temp.gadgets = Gadgets.objects.filter(id__in=data.getlist('gadgets'))
in the VIEW:
manipulator = UserprofileManipulator()
user_profile_manipulator = UserProfile.ChangeManipulator
(request.user.id)
user_profile = user_profile_manipulator.original_object
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data)
manipulator.save(new_data)
else:
errors = {}
new_data = user_profile_manipulator.flatten_data()
...
PROBLEMS:
1. the m2m-relationship doesn´t get saved.
2. in the template i have to write {{ form.gadgets_id }} to output
the checkboxes ... instead of {{ form.gadgets }}
thanks,
patrick
