I have form for adding data in database and I want to restrict foreign key choices in my dropdown menu. It have to be restricted on my finishDate field. If finishDate is date before today (eg. today is 21-08-2016 and finishDate is 30-06-2013), then I don't want to show foreign key value of that finishDate. What is the easiest way to do this? I am relative new at this, so I need help.
models.py
class Account(models.Model):
startDate = models.DateField(verbose_name="Start")
finishDate = models.DateField(verbose_name="Finish")
def __str__(self):
return 'A{}'.format(self.id)
class Net(models.Model):
date = models.DateTimeField(default=datetime.now())
MB = models.IntegerField(validators=[MinValueValidator(1)],default=randint(100,2000))
idAccount = models.ForeignKey(Account, on_delete=models.CASCADE, verbose_name="Account")
def __str__(self):
return 'Record {}'.format(self.datum)
forms.py
class NetForm(ModelForm):
class Meta:
model = Net
fields = ['idAccount']
views.py
@login_required(login_url="/accounts/login/")
def net(request):
if request.method == 'POST':
form = NetForm(request.POST)
if form.is_valid():
internet = form.save()
return HttpResponseRedirect('/')
else:
form = NetForm()
return render(request, 'project/Net.html', {'form': form})
Thanks a lot!
