Workaround Firefox bug 553888

Firefox transparently follows redirects when AJAX calls return 3xx code. And it drops additional headers, X-Requested-With among them. Server treats redirected HTTP requested as non-AJAX. JS libraries has nothing to do here. At 16.03.11 bug https://bugzilla.mozilla.org/show_bug.cgi?id=553888 has status "NEW" being reported at 21.03.10. Workaround is following: - in process_response(): if request.is_ajax() and response has status_code 3xx then put response["Location"] to session, otherwise unset session stored value (if it is there). - in process_request(): if not request.is_ajax() and request.path equals to stored session value then monkeypatch request.is_ajax() return True (before any views come into play). This results in smooth transparent redirects in Firefox, all treated as AJAX calls.

Finding related objects for instances in a queryset

When deleting objects in Django's admin interface, it lists other objects which would be deleted and asks for confirmation. This snippet does the same programmatically. The snippet works in Django 1.3 (more specifically, revision 14507 or later). It uses Django internals which are not a part of the public API, so this might not work with future versions. Usage: `polls/models.py`: from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) def __unicode__(self): return self.question class Choice(models.Model): poll = models.ForeignKey(Poll) choice = models.CharField(max_length=200) def __unicode__(self): return '%s %s' % (self.poll, self.choice) `$ ./manage.py shell` >>> from polls.models import Poll, Choice >>> from datetime import datetime >>> from pprint import pprint >>> poll1 = Poll.objects.create(question='Me?') >>> Choice.objects.create(poll=poll1, choice='Yes') >>> Choice.objects.create(poll=poll1, choice='No') >>> poll2 = Poll.objects.create(question='Really?') >>> Choice.objects.create(poll=poll2, choice='Yes') >>> Choice.objects.create(poll=poll2, choice='No') >>> pprint(get_related(Poll.objects.all())) {<class 'polls.models.Poll'>: [<Poll: Me?>, <Poll: Really?>], <class 'polls.models.Choice'>: [<Choice: Me? Yes>, <Choice: Me? No>, <Choice: Really? Yes>, <Choice: Really? No>]}

currency filter without using locale

This snippet is a combination of the existing currency snippets I found and some modifications to use your own settings without the need to have the locale installed on the system. You can define in settings.py: DECIMAL_SEPARATOR = ',' THOUSAND_SEPARATOR = '.' CURRENCY_SYMBOL = u'€' With the above settings, using `{{ 1234.30|currency }}` on a template would result in `€1.234,30`

Group sequence into rows and columns for a TABLE

Two template tag filters that can be used to create a table from a sequence. <table> {% for row in object_list|groupby_columns:3 %} <tr> {% for obj in row %} <td>{{ obj }}</td> {% endfor %} </tr> {% endfor %} </table> The example above would create a table where items read from top to bottom, left to right, in 3 columns. "Empty" cells are added to the sequence by the filter so that your rows balance.
