Using a Django template_tag on pages that extend from the view that loads the tag

问题

I've added a template tag to my app which I load in a view located in inc/base.html. This view contains my basic HTML layout. All my other views begin {% extends "inc/base.html" %}.

In one of my views I want to refer to my template tag, which is loaded in inc/base.html using this code: {% load spb_utils %}. If I try to use on of the template tags inside base.html it works fine, but if I try it any other view, it errors unless I manually add {% load spb_utils %} to the extended view as well.

Is this behaviour intentional? Eg, if I extend a template, does Django deliberately not load any of the template tags the 'parent' template loads? Is there a smart way to globally load my tags?

thanks.

回答1:

that is the correct behaviour. extending a template does not load its template tags.

for always loading tags, see this answer, though you should carefully consider whether you really want this:
