Creating new Objects instead of updating - Django - django

Question

I am trying to use Update in Django, but it is not being updated, rather a new object of the model is being created in the database.
For example, if I try to change product label "Laptop" to "Smartphone", Django creates a new product called "Smartphone" instead of updating "Laptop".
This is my code
Model:
class Products(models.Model):
label = models.CharField(max_length=50)
description = models.CharField(max_length=250)
first_price = models.FloatField(null=True)
price = models.FloatField()
quantity = models.IntegerField(default=0)
image = models.ImageField(null=True, blank=True)
def __str__(self):
return self.label
#property
def imageURL(self):
try:
url = self.image.url
except:
url = ''
return url
Form:
class ProductForm(ModelForm):
class Meta:
model = Products
fields = ['label', 'description', 'first_price', 'price', 'quantity', 'image']
View:
#login_required(login_url='login')
def editProduct(request, id):
product = Products.objects.get(id=id)
form = ProductForm(instance=product)
if request.method == 'POST':
form = ProductForm(request.POST, request.FILES)
if form.is_valid():
form.save()
messages.success(request, 'Product was edited.')
return redirect('index')
context = {
'form': form
}
return render(request, 'store/edit-product.html', context)
Template:
<h3>Edit Product</h3>
<form method="POST" enctype="multipart/form-data">
{% csrf_token %}
{{ form.label.label }}
{{ form.label }}
{{ form.description.label }}
{{ form.description }}
{{ form.first_price.label }}
{{ form.first_price }}
{{ form.price.label }}
{{ form.price }}
{{ form.quantity.label }}
{{ form.quantity }}
{{ form.image.label }}
{{ form.image }}
<input type="submit" name="Add product">
{{form.errors}}
</form>
Thank you in advance.

To update an object, it needs to be passed to the form, so:
product = Products.objects.get(id=id)
form = ProductForm(instance=product)
if request.method == 'POST':
form = ProductForm(request.POST, request.FILES, instance=product)
# ^^^ Add this
Otherwise without instance, the form will work as if you are trying to create a new object
