Stuff I always forget about CBVs

• self.request is the way to get the request object
• self.args and self.kwargs are the URL parameters from urls.py (they are also passed to almost every method, but they're not always, and some methods take an args and kwargs that aren't the ones from the URL, so... just use self. everywhere!)
• dispatch is called before get or post so is a useful place to setup stuff you need everywhere
• the view object itself is available in the template as view, so templates can access view methods and properties
• Detail and List views don't just get the template variables object and object_list, they also get <model-name> and <model-name>_list
• Permission decorators etc are better handled by django-braces

register = template.Library()

@register.simple_tag(takes_context=True)
def query_transform(context, **kwargs):
    '''
    Returns the URL-encoded querystring for the current page,
    updating the params with the key/value pairs passed to the tag.

from django.utils.http import urlencode

    '''Custom reverse to handle query strings.
    Usage:
        reverse('app.views.my_view', kwargs={'pk': 123}, query_kwargs={'search': 'Bob'})
    '''
    base_url = reverse(view, urlconf=urlconf, args=args, kwargs=kwargs, current_app=current_app)
    if query_kwargs:
        return '{}?{}'.format(base_url, urlencode(query_kwargs))
