Please, I need your help because I'm trying to solve a problem
I'm making a questionnaire and I want to count the number of the selected
choices in a certain question
The model I'm using is:
class Reuse(models.Model):
REUSE_OPTIONS = (
('1', 'first choice'),
('2', 'second choice'),
('3', 'third choice'),
('4', 'fourth choice'),
('5', 'none of the above'),
)
user = models.ForeignKey(settings.AUTH_USER_MODEL, null=True,
blank=True)
reuse = MultiSelectField(max_length=250, choices= REUSE_OPTIONS,
max_choices=4, null=True)
m = models.DecimalField(max_digits=5, decimal_places=3, default=0)
numchoices = models.IntegerField()
def numchoices(self): (I
tried this but it didn't work)
self.choices_count = self.choice_set.count()
self.save()
I wrote this view:
def reuse (request):
if request.method == "POST":
form = ReuseForm(request.POST)
if form.is_valid():
reuse = form.save(commit=False)
# if reuse.get_choices.count() == 1 : reuse.m=0.075
(this doesn't work either)
# elif reuse.get_choices.count() == 2 : reuse.m=0.15
# elif reuse.get_choices.count() == 3 : reuse.m=0.225
# elif reuse.get_choices.count() == 4 : reuse.m=0.3
reuse.save()
return redirect('../22')
else:
form = ReuseForm()
return render(request, '../reuse.html', {'form':form})
And the form I'm using is:
class ReuseForm(forms.ModelForm):
class Meta:
model = Reuse
fields = ('reuse',)
Please, have you got any suggestions;
Thank you in advance
