Re: Need urgent help with filter system (django-filter) in Django

This isn't working. When we are supplying a filter, the html is displaying all the products irrespective of the requested.

Hi,

I've been trying to introduce a filter system in my Django-ecommerce website and I've been struggling despite reading the documents, etc. I am using 'django-filter' and below are filters.py, models.py, views.py and the template. To check out the project, follow the github link: https://github.com/First-project-01/Django-ecommerce.

Will be grateful if anyone can sort this out. Thanks in advance.

Regards,

Aritra
