Re: NOT NULL constraint failed when trying to create form with initial values
That did the trick. There were some minor errors after it, but now there
isn't. By the way, I tried this solution before I tried the "initial"
solution but it didn't work at that time. Many thanks.

There is a convention in Django (models and ORM), "object.foreign_key"
gives you the object, while "object.foreign_key_id" gives you the id of
that object (and is what it is stored in the database). You should name
your field only "contest" for avoiding confusions.

Alright, for tomorrow then:
I don't usually use "initial" but if you are excluding (or not including)
the field in the form, "initial" would not be useful. A workaround would be:
if form.is_valid():
photo = form.save(commit=False)
photo.contest = random_item
photo.owner = 'SUMMERSON'
photo.save()

I tried with both 'contest': random_item and 'contest_id':
random_item.contest_id. (I don't know why you wrote contest instead of
contest_id. Field name is contest_id)
That's because what you are passing is empty and the field is required.

Re: NOT NULL constraint failed when trying to create form with initial values
Oh, that's a life saver information. Thanks. I edited my code.
Unfortunately, only thing that has changed is the name of the error which
looks like this right now: NOT NULL constraint failed:
photo_photo.contest_id
I'm going to take a break and try to solve the problem tomorrow. I
appreciate your help.

Are you sure that you have Contest objects?
There is a convention in Django (models and ORM), "object.foreign_key"
gives you the object, while "object.foreign_key_id" gives you the id of
that object (and is what it is stored in the database). You should name
your field only "contest" for avoiding confusions.

Re: NOT NULL constraint failed when trying to create form with initial values
Yes, photo_id is PK. So I shouldn't even give its value to the form in
initial values I guess?
Contest_id isn't PK, I want to select a random contest id from contest
objects. (I decided to do this just now, my former code does not include
this :) )
By the way, contest_id is foreign key in Photo. It is a PK in Contest. What
am I doing wrong now? It gives the exact same error.
items = Contest.objects.all()
random_item = random.choice(items)
if request.method =='POST':
data = {'contest_id': random_item.contest_id,
'ownername': 'SUMMERSON',
}
form=PhotoForm(request.POST, initial=data)
if form.is_valid():
Photo = form.save()
else:
form = PhotoForm()

Re: NOT NULL constraint failed when trying to create form with initial values
You shouldn't give the PK of new objects, leave that to Django. If photo_id
is the PK of Photo, don't set it, Django will on save.
If the same goes for Contest, then do a "contest = Contest()" - create a
new contest - and assign it to the photo "photo.contest = contest", then
"photo.save"

NOT NULL constraint failed when trying to create form with initial values
Hi. I'm trying to create a form to construct an object for my Photo class.
All of the objects fields except the photo itself will be invisible to the
user. So, the only thing can be seen in the form is the button to select
and upload the photo.
There is no problem with creating the form page. The problem is, giving the
initial values for the rest of the fields.
This is the relevant code in my view file:
if request.method =='POST':
data = {'photo_id': get_latest_photo_id_plusone(),
'contest_id': get_latest_contest_id_plusone(),
'ownername': 'SUMMERSON',
}
form=PhotoForm(request.POST, initial=data)
if form.is_valid():
Photo = form.save()
else:
form = PhotoForm()
And the relevant functions:
def get_latest_photo_id_plusone():
max_rating =
Photo.objects.all().aggregate(Max('photo_id'))['photo_id__max']
return max_rating+1
def get_latest_contest_id_plusone():
max_rating
=Photo.objects.all().aggregate(Max('contest_id'))['contest_id__max']
return max_rating+1
The error arises when I click on the send button after I select the image.
It says:
IntegrityError at /photo/create/
NOT NULL constraint failed: photo_photo.contest_id_id
But I've given the contest_id value. Haven't I? Where is the problem and
how can I fix it?
