Hello everyone,
I have been working for hours trying to understand the following problem: I have a user send an Ajax request to dynamically send a form and record that the number of forms to read on submission has increased. Toward this end I use request.session['editing_foo'] = { 'prefix_of_form_elements' : pkey }
so that I can associate them with the database for saving and loading (-1 is for new forms that haven't been saved yet).
However, when I use the following code (see bottom) I get the following bizarre output:
1st Click:
{} foousername
next_key 1
1
{u'1-foo': -1}
2nd Click:
{} foousername
next_key 1
1
{u'1-foo': -1}
3rd Request:
{} foousername
next_key 1
1
{u'1-foo': -1}
What the heck is going on?
id_fetcher = re.compile(r'\d')
@login_required
def ajax_add_foo(request):
def id_from_prefix(key):
return int( id_fetcher.search(key).group(0) )
if 'editing_foos' not in request.session:
print "reinitializing"
request.session['editing_foos'] = {}
print request.session['editing_foos'], request.user
keys = request.session['editing_foos'].keys()
if len(keys) == 0:
next_key = 1
else:
print [ id_from_prefix(key) for key in keys ]
next_key = max([ id_from_prefix(key) for key in keys ]) + 1
print "next_key", next_key
fooform = FooForm(prefix=next_key)
print next_key
request.session['editing_foos'].update( {create_prefix(FooForm, next_key) : -1 } ) # This quote is new and has no pkey
print request.session['editing_foos']
return render_to_response( 'bar/foo_fragment.html',
{'fooform' : fooform, },
context_instance=RequestContext(request))
Thank you all very much!
