Django how to save a custom formset - django

Question

I've written the following custom formset, but for the life of me I don't know how to save the form. I've searched the Django docs and done extensive searches, but no one solution works. Lots of rabbit holes, but no meat ;-) Can someone point me in the right direction?
// views.py partial //
#login_required
def add_stats(request, group_slug, team_id, game_id, template_name = 'games/stats_add_form.html'):
if request.POST:
formset = AddStatsFormSet(group_slug=group_slug, team_id=team_id, game_id=game_id, data=request.POST)
if formset.is_valid():
formset.save()
return HttpResponseRedirect(reverse('games_game_list'))
else:
formset = TeamStatFormSet(group_slug=group_slug, team_id=team_id, game_id=game_id)
return render_to_response(template_name, {'formset': formset,})
// modles.py partial //
class PlayerStat(models.Model):
game = models.ForeignKey(Game, verbose_name=_(u'sport event'),)
player = models.ForeignKey(Player, verbose_name=_(u'player'),)
stat = models.ForeignKey(Stat, verbose_name=_(u'statistic'),)
total = models.CharField(_(u'total'), max_length=25, blank=True, null=True)
class Meta:
verbose_name = _('player stat')
verbose_name_plural = _('player stats')
db_table = 'dfusion_playerstats'
def __unicode__(self):
return u'%s' % self.player
// forms.py
class TeamStatForm(forms.Form):
total = forms.IntegerField()
class BaseTeamStatsFormSet(BaseFormSet):
def __init__(self, *args, **kwargs):
self.group_slug = kwargs['group_slug']
self.team_id = kwargs['team_id']
self.game_id = kwargs['game_id']
self.extra = len(Stat.objects.filter(group__slug=self.group_slug))
del kwargs['group_slug']
del kwargs['game_id']
del kwargs['team_id']
super(BaseTeamStatsFormSet, self).__init__(*args, **kwargs)
def add_fields(self, form, index):
super(BaseTeamStatsFormSet, self).add_fields(form, index)
form.fields["stat"] = forms.ModelChoiceField(queryset = Stat.objects.filter(group__slug=self.group_slug))
form.fields["game"] = forms.ModelChoiceField(queryset = Game.objects.all())
form.fields["team"] = forms.ModelChoiceField(queryset = Team.objects.all())
form.fields["game"].initial = self.game_id
form.fields["team"].initial = self.team_id
TeamStatFormSet = formset_factory(TeamStatForm, BaseTeamStatsFormSet)

Answer 1

In your custom forms, you'll need to add a save() method that stuffs the form data into your models as needed. All of the data entered in the form will be available in a hash called cleaned_data[].
For example:
def save(self):
teamStat = TeamStat(game_id=self.cleaned_data['game_id'],team_id=self.cleaned_data['team_id'])
teamStat.save()
return teamStat

Answer 2

Only model forms and formsets come with a save() method. Regular forms aren't attached to models, so you have to store the data yourself. How to save a formset? from the Django mailing list has an example of saving data from a regular formset.
Edit: You can always add a save() method to a regular form or formset as gbc suggests. They just don't have one built-in.
I don't see a TeamStat model in your code snippets, but if you had one, your forms.py should look something like this:
class TeamStatForm(forms.ModelForm):
total = forms.IntegerField()
class Meta:
model = TeamStat
class BaseTeamStatsFormSet(BaseModelFormSet):
def __init__(self, *args, **kwargs):
self.group_slug = kwargs['group_slug']
self.team_id = kwargs['team_id']
self.game_id = kwargs['game_id']
self.extra = len(Stat.objects.filter(group__slug=self.group_slug))
del kwargs['group_slug']
del kwargs['game_id']
del kwargs['team_id']
super(BaseTeamStatsFormSet, self).__init__(*args, **kwargs)
def add_fields(self, form, index):
super(BaseTeamStatsFormSet, self).add_fields(form, index)
form.fields["stat"] = forms.ModelChoiceField(queryset = Stat.objects.filter(group__slug=self.group_slug))
form.fields["game"] = forms.ModelChoiceField(queryset = Game.objects.all())
form.fields["team"] = forms.ModelChoiceField(queryset = Team.objects.all())
form.fields["game"].initial = self.game_id
form.fields["team"].initial = self.team_id
TeamStatFormSet = modelformset_factory(TeamStatForm, BaseTeamStatsFormSet)
