template timings section is empty in debug toolbar panel

[kushagra219]

This is my settings.py part for the django-debug-toolbar and django-debug-toolbar-template-timings, but all the sections are displaying something in toolbar except template-timings which was really required as one of my templates is taking too much time to load and I can't figure out why! how can I rectify this issue?

I have the same issue here. For information my configuration is: Python 3.7.9 Django 3.1.1 Debug Toolbar 3.1.1 Note that all other panels work fine, and this panel is the only third party I have

From the documentation, debug-toolbar-template-timings doesn't work with Django 2.0 and above.

Since django-debug-toolbar 2.0, the process_response method is deprecated. That's why the stats for template timings panel it not collected.

I can fix it by creating a new file called debug_toolbar_template_timings.py The content is as below:

from template_timings_panel.panels.TemplateTimings import TemplateTimings

class TemplateTimingsFixed(TemplateTimings):
    def process_request(self, request):
        response = super().process_request(request)
        self.process_response(request, response)
        return response

Finally, change you django settings, from 'template_timings_panel.panels.TemplateTimings.TemplateTimings', to 'debug_toolbar_template_timings.TemplateTimingsFixed',

It will work as expected.
