django-filterview is a class based view on top of generic ListView with filtering of the queryset by mapping URL params into filter() arguments.

Just download source code and extract filterview directory to your PYTHON_PATH. No changes in settings.py required.

In your urls.py insert this line:

from filterview import FilterView

Then just define url pattern with named params and FilterView.as_view() as url processing view. The only required FilterView.as_view() arguments are model and mapping. First one plays the same role as model argument of ListView. mapping is dictionary for mapping url params values to filter() arguments. For example:

{
	'name': lambda key, value: [('first_name', value)],
	
	'age': lambda key, value: [(
		'birthdate__range', (
			datetime.today() - timedelta( days=366*int(value.split('-')[1]) ),
			datetime.today() - timedelta( days=365*int(value.split('-')[0]) ),
		)
	)],
}

django-filterview accepts all ListView arguments and additionally mapping argument.

Required arguments are:

• model - filtering queryset model object
• mapping - dictionary with keys named like url params and function object returning list of tuples.

mapping dictionary function object takes url param name and its value as arguments. Each tuple of returned list has two items - first one is filter() argument name and the last is its value. So each url param can be mapped into two or more filter() argument.

Note: if some url param is not presented in mapping dictionary it's taken from url and used in filter() with no changes.

Using above example mapping dictionary and url pattern

r'^(/(?P<name>[\w\d\s%]+))?(/(?P<gender>(M|F)))?(/(?P<age>[\d]+\-[\d]+))?/?$'

Result filter() arguments for url /Jhon/M/30-37 are:

filter(first_name=<value for name url param>, gender=<value for gender url param>, birtdate__range=(

	datetime.today() - timedelta( days=366*int(value.split('-')[1]) ),
	datetime.today() - timedelta( days=365*int(value.split('-')[0]) ),
	
))
