You didn't return anything at all from your do_thing view, hence the error.
However you shouldn't really call one view from the other. If you do that,
the browser will show the URL of the main view, which will be confusing.
Instead, after running the task, *redirect* back to the main view:
from django.shortcuts import redirect
...
return redirect('mes.views.main_table')
