Django template tag to insert or replace URL parameter

Question

Is anyone aware of a Django template tag that takes the current path and query string and inserts or replaces a query string value?

e.g. given a request to /some/custom/path?q=how+now+brown+cow&page=3&filter=person

The call {% urlparam 'page' 4 %} would generate /some/custom/path?q=how+now+brown+cow&page=4&filter=person.

This wouldn't be too difficult to write from scratch, but as this seems like a very common task, I would expect a tag like this to be built-in. However, after reading through the docs and googling, I can't seem to find anyone's who's publicized such a tag.

Since I haven't used these tools by my own, I'll just refer you:

• django-url-tools has url_params template tag that seems to do what you want
• django-more-template-tags-and-filters has some helper tags for manipulating urls and parameters

FYI, I've personally used jsurl library for this kind of url manipulations in javascript.

Hope that helps.
