Django templatetags to simplify creating, updating, and removing query parameters from querystring

Project description

django-query-parameters

Adds two template tags that simplify the manipulation of GET parameters on a querystring. Allows easy addition, manipulation, and deletion of parameters onto an existing querystring.

The module is comprised of two template tags: set_query_parameters and del_query_parameters.

set_query_parameters

Takes a 1+ list of key=value pairs and generates an updated querystring that includes those pairs. If a key does not already exist in the querystring, it will be added. If a key exists, it will be updated with the new value. For example:

# current page is http://localhost/?page=1&limit=20
{% load query_parameters %}
<a href="?{% set_query_parameters page=2 order=desc %}">...</a>
# => <a href="?page=2&limit=20&order=desc">...</a>

del_query_parameters

Takes a 1+ list of keys and generates an updated querystring that removes those keys. If a key does not exist in the query string, it will be ignored. For example:

# current page is http://localhost/?page=1&limit=20
{% load query_parameters %}
<a href="?{% del_query_parameters page order %}">...</a>
# => <a href="?limit=20">...</a>
