Hi,

I wonder how would I access context and set the key/value pair from within custom template tag?

Later on I want to access context object in djang-debug-toolbar panel with

from django.template import RequestContext; rc = RequestContext(request)

rc contains all the context that had been passed on to TemplateResponse within the view, o I want to add few more there from the template tag and just cant figure out how.

Thanks a lot for any ideas!

First thing that comes to mind:

https://docs.djangoproject.com/en/2.2/howto/custom-template-tags/#setting-a-variable-in-the-context

If you'll be using these same variables in a majority of your templates, then I'd recommend looking at a custom template context processor:

https://docs.djangoproject.com/en/2.2/howto/custom-template-tags/#setting-a-variable-in-the-context

That way you can define constants in you application code and have them automatically pulled in as template variables in all your templates without having to repeat a template tag in every template.
