Answer 1

Firstly in your form you set model = ProfileModel but your model is Profile correct that:
class ProfileForm(forms.ModelForm):
class Meta:
model = Profile
fields = ['profile_pic']
Next in your view in case of a POST request your view is completely wrong. You try to make an instance of Profile and call it form and save it. This is likely failing. Also I assume you write 'SESSION_KEY' in request.session in an attempt to check if the user is logged in, instead use request.user.is_authenticated or in fact disallow anonymous users from accessing your views by using the login_required decorator. Change it like so:
from django.contrib.auth.decorators import login_required
#login_required
def uploadPic(request):
if request.method == 'POST':
form = ProfileForm(request.POST, request.FILES)
if form.is_valid():
form.instance.user = request.user
form.save()
return redirect('home')
else:
form = ProfileForm()
return render(request, 'upload.html', {'form': form})
Note: The indentation of my answer is 4 spaces which is different from your indentation. It is best to indent by 4 spaces for readability. Check about indentation in PEP 8 which is the Style Guide for Python Code.
