I'm confused with how django adds elements to a list. consider the
following:
def add(request):
if request.method == "POST":
form = NewTaskForm(request.POST)
if form.is_valid():
task = form.cleaned_data["task"]
request.session['tasks'].append(task)
# request.session['tasks'] += [task]
return HttpResponseRedirect(reverse("tasks:index"))
else:
return render(request, "tasks/add.html",{
"form": form
})
return render(request, "tasks/add.html",{
"form": NewTaskForm()
})
if we add a print statement after request.session['tasks'].append(task) we
get a list:
['check email']
we also get the same list if we comment the append line and use the correct
way with +=
However, on the redirect to task/index the first way shows an empty list
and the second way shows the list that's expected. Why? Whats going on?
