webstack-django-sorting 0.4.1

Easy sorting of tables with Django

webstack-django-sorting allows for easy sorting, and sorting links generation without modifying your views. It is the perfect companion of linaro-django-pagination”,

There are really 5 steps to setting it up with your projects.

1. List this application in the INSTALLED_APPS portion of your settings file. Your settings file might look something like:

   INSTALLED_APPS = (
       # ...
       'webstack_django_sorting',
   )

2. Install the sorting middleware. Your settings file might look something like:

   MIDDLEWARE_CLASSES = (
       # ...
       'webstack_django_sorting.middleware.SortingMiddleware',
   )

3. If it’s not already added in your setup, add the ‘request’ context processor:

   TEMPLATE_CONTEXT_PROCESSORS = (
       'django.contrib.auth.context_processors.auth',
       'django.core.context_processors.debug',
       'django.core.context_processors.i18n',
       'django.core.context_processors.media',
       'django.core.context_processors.static',
       'django.core.context_processors.tz',
       'django.core.context_processors.request',
       'django.contrib.messages.context_processors.messages',
   )

   This example comes from Django 1.6, take care to check against your Django version which context processors are supported (see global_settings.py file of your Django installation).

4. Add this line at the top of your template to load the sorting tags:

   {% load sorting_tags %}

5. Decide on a variable that you would like to sort, and use the autosort tag on that variable before iterating over it:

   {% autosort object_list %}

6. Now, you want to display different headers with links to sort your objects_list:

   <tr>
       <th>{% anchor first_name _("Name") %}</th>
       <th>{% anchor creation_date _("Creation") %}</th>
   </tr>

   The first argument is a field or an attribute of the objects list, and the second one (optional) is a title that would be displayed. The previous snippet will be rendered like this in French:

   <tr>
       <th><a href="/path/to/your/view/?sort=first_name" title="Nom">Nom</a></th>
       <th><a href="/path/to/your/view/?sort=creation_date" title="Création">Création</a></th>
   </tr>

   If your application doesn’t support internationalization, you can use a simple {% anchor first_name Name %}.

That’s it!
