How can i submit two forms in django - django

Question

I have a template where i should have 2 forms and update them, I succeded to get the 2 foms in the same template, but when i make changes nothing happens !
forms.py
class OrderManageForm(forms.ModelForm):
class Meta:
model = Order
fields = ['customer', 'product', 'quantity', 'status']
class CustomerForm(forms.ModelForm):
address = forms.CharField(widget=forms.Textarea(attrs={'rows': 5}))
class Meta:
model = Customer
fields = ['full_name', 'address', 'phone', 'city', 'email'
models.py
class Customer(models.Model):
full_name = models.CharField(max_length=150)
address = models.CharField(max_length=1500, null=True)
phone = models.CharField(max_length=20)
city = models.CharField(max_length=100)
email = models.EmailField(null=True)
def __str__(self):
return self.full_name
class Order (models.Model):
product = models.ForeignKey(Product, on_delete=models.CASCADE)
customer = models.ForeignKey(Customer, on_delete=models.CASCADE,)
quantity = models.IntegerField(default=1)
status = models.TextField(choices=ORDER_STATUS, default='Pending')
def __str__(self):
return 'Order n°: ' + str(self.id)
views.py
def update_order(request, order_id):
order = get_object_or_404(Order, id=order_id)
cust = get_object_or_404(Customer, order__id=order_id)
if request.method == 'POST':
customer = CustomerForm(request.POST)
form = OrderManageForm(request.POST)
print(request.POST)
if form.is_valid() and customer.is_valid():
order = form.save(commit=False)
customer = customer.save()
order.customer = customer
order.save()
return redirect('orders')
else:
form = OrderManageForm(instance=order)
customer = CustomerForm(instance=cust)
return render(request, 'dashboard/order_details.html', {'form': form, 'customer': customer})
I put the 2 forms in only one form tag inside my HTML template

You need to feed the instances to the forms such that the forms can update the corresponding records:
def update_order(request, order_id):
order = get_object_or_404(Order, id=order_id)
cust = order.customer
if request.method == 'POST':
customer = CustomerForm(request.POST, instance=cust)
form = OrderManageForm(request.POST, instance=order)
if form.is_valid() and customer.is_valid():
form.save()
customer.save()
return redirect('orders')
# …
You should only redirect in case the two forms are valid, otherwise you can not see the errors that appear on the form. Furthermore you shoudld remove the customer from the fields of the OrderManageForm:
class OrderManageForm(forms.ModelForm):
class Meta:
model = Order
fields = ['product', 'quantity', 'status'] ← no customer
