Some more information. The view method to save the item is as follows:
def update_project(request, slug):
'''Method for editing already existing projects.'''
project = get_object_or_404(Project, slug=slug)
if request.method == 'POST': # If form was submitted run it
through.
form = ProjectForm(request.POST)
if form.is_valid():
form_instance = form.save(commit=False)
form_instance.id = project.id
form_instance.created_on = project.created_on
form_instance.save()
return HttpResponseRedirect(reverse('view-project', args=
[slug]))
else:
form = ProjectForm(instance=project)
return render_with_context(request, 'project/projectedit.xhtml', {
'form': form,
'action': reverse('update-project',
args=[slug]),
'button': 'Update Project',
'title': 'Editing Project'
})
