Stuck With Django Form Validation

I'm trying to get validation running on a django form used to retrieve a list of objects in a ListView View. Despite having read django docs and many other questions here, I can't

Solution 1:

The default a FormView will only process the form on POST; the GET is for initially displaying the empty form. So you need to use method="post" in your template form element.

Your action attribute is also suspect; it needs to point to the URL of the form view. If that actually is the URL, note it's not usual to use extensions like ".html" in Django URLs, and I would recommend not doing so.
