Use saved form instead of cleaned form django - django

Question

I am not able to display the invoice number in the receipt.html.
invoice number is auto generated in models.py
models.py
from random import randint
class Buyer(models.Model):
name_of_buyer = models.CharField(max_length=200,null=True)
address_of_buyer = models.CharField(max_length=200,null=True)
interested_in = models.ForeignKey(Box,on_delete=models.CASCADE,null=True)
Pickup_dt = models.DateField(null=True)
Pickup_time = models.CharField(max_length=80,null=True)
Invoice_number = models.CharField(max_length=12,blank=True,unique=True)
def save(self, *args, **kwargs):
if self.interested_in == 'Mangos':
x=randint(99,99999)
self.Invoice_number = str('MAN') + str(x)
elif self.service == 'Banana':
x=randint(99,99999)
self.Invoice_number = str('BAN') + str(x)
elif self.service == 'Apple':
x=randint(99,99999)
self.Invoice_number = str('APP') + str(x)
super(imfc_one,self).save()
def __str__(self):
return str(self.Invoice_number)
forms.py
class Sale(forms.ModelForm):
def clean_interested_in(self):
buyer_interested_in_box = self.cleaned_data['interested_in']
if buyer_interested_in_box.mango < 10:
raise forms.ValidationError('Not enough fruits.Please select another box')
class Meta:
model = Buyer
fields = '__all__'
view.py
def ind(request):
form = Sale()
if request.method == 'POST':
form = Sale(request.POST)
if form.is_valid():
form.save(commit=True)
return render(request,'app_one/receipt.html',{'upform':form.cleaned_data})
else:
print("form is not vaalid")
return render(request,'app_one/index1.html',{'form':form})
receipt.html
receipt : {{ upform.Invoice_number }}
How can I have the invoice number in the receipt.html
Thank you.

You don't have to pass form.cleaned_data in view. Just pass your saved object
def ind(request):
form = Sale()
if request.method == 'POST':
form = Sale(request.POST)
if form.is_valid():
buyer = form.save(commit=True)
return render(request,'app_one/receipt.html',{'buyer': buyer})
else:
print("form is not vaalid")
return render(request,'app_one/index1.html',{'form':form})
In receipt.html, just call
receipt : {{ buyer.Invoice_number }}
