VIEWS

def ProjektView(request, pk ):
profil = Profil.objects.get(user=request.user)
projekt = profil.projekt_set.all()
srodek = Srodek.objects.filter(id=pk)

if request.method == "POST":
    form = OptionsForm(request.POST or None, request.FILES or None)
    if form.is_valid():
        form.save()


template_name = 'viewProjekt.html'
context = {
    'projekt':projekt,
    'srodek':srodek,


}
return render(request, template_name, context)

If i tried srodek = Srodek.objects.all() this works but dont fine, becouse each Projekt has the same Srodek Demonstrative Photo

Answer 1

You need to change the variable name of id, id is a built in function in python that returns the identity of an object. I think this is the cause of your error.

You second error is its expecting a hexadecimal string and you are not providing one in the correct format. You need to convert the string given from the from to a hexadecimal format.

Answer 2

I dont think so that problem, is in uuid.uuid4. I tried uuid.uuid4().hex. If i use uuid.uuid4 all was good. http://127.0.0.1:8000/projekty/view_projekt/bd7ce422-1951-4225-8099-37e15e9ac2cf/. This work correct, but when i try update i have this problem with uuid

Answer 3

Here is a complete error

Here is a complete error

Answer 4

I fix this "srodek = Srodek.objects.filter(projekt_id=pk)", but i got next problem... When i use option update, i got next error "['“3” is not a valid UUID.']"
