Custom model field to store dict object in database

**Disclaimer** This is proof of concept snippet, It can not be considered as best practice. Seems like it's better to store (key => value) in sepetare model with 'key' and 'value' fields. **Example** You can assign any dict to model field that can be dumped/serialized with Django json encoder/decoder. Data is saved as TextField in database, empty dict is saved as empty text. Tested with Django 1.2beta. import DictionaryField class UserData(models.Model): user = models.ForeignKey(User) meta = DictionaryField(blank=True) There are similar snippets: [JSONField 1](http://www.djangosnippets.org/snippets/377/) or [JSONField 2](http://www.djangosnippets.org/snippets/1478/).

View decorator providing confirmation dialog

Decorator for views that need confirmation page. For example, delete object view. Decorated view renders confirmation page defined by template 'template_name'. If request.POST contains confirmation key, defined by 'key' parameter, then original view is executed. Context for confirmation page is created by function 'context_creator', which accepts same arguments as decorated view.

Widget for CommaSeparatedIntegerField with pre-defined choices

Widget for editing CommaSeparatedIntegerField with a set of checkboxes. Each checkbox corresponds to single integer value. So, choices should be pre-defined for widget. **Example** Assume, we need a registration form for some event with time frame for 3 days, starting at Monday. User can select any of 3 days, so we need to show 3 checkboxes. Here's the basic example for such form: class EventRegistrationForm(forms.Form): days = forms.CharField(widget=NumbersSelectionWidget( ['Mon', 'Tue', 'Wed'], range(1, 4)))
