"user_id" is empty when setting MyForm(data=data) (Django) - django

Question

I have the following model
#models.py
class MyModel(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete = models.CASCADE,null=True)
link = models.URLField(max_length=2048)
date_added = models.DateTimeField(default = timezone.now)
used = models.BooleanField(default = True)
and my form
class MyModelForm(forms.ModelForm):
class Meta:
model = Wishlist
exclude = [
"user","date_added"
]
when I in my view try to "manually" create an instance (in the for-loop) and save it, the "user_id" in my database is NULL
#views.py
def AddLink(request):
user = request.user
instance = MyModel(user=user)
if request.method == "POST":
form = MyModelForm(request.POST,instance = instance)
if form.is_valid():
link = form.instance.wishlist
used = form.instance.discount_pct
#some util function to do some stuff
res = my_util_func(link,api_key)
for used, link in zip(res[0],res[1]):
data = {"link":link,"used":used}
form = MyModelForm(data=data)
form.save()
context = {
"results":res}
return render(request, "discounttracker/myhtml.html",context=context)
I have tried changing data to data = {"link":link,"used":used,"user":user} and data = {"link":link,"used":used,"user_id":user} but it is still empty.
How can I add the user here?

Answer 1

There is a secret option in ModelForm.save() called commit that allows you to not save the form right now, but instead return a model and insert some data into it. This should work perfectly here
form = MyModelForm(data=data))
instance = form.save(commit=False)
instance.user = request.user
instance.save()
This sample inserts the currently logged in user into the user field on your model.
