Django signals not working properly

Question

I\'m trying to setup a signal so that when a valid form is saved, a function is ran to carry out a related task.

My app structure is as follows;

- ev         


        

Answer 1

I found one case that signal is not working.

Here are cases that signal(pre_save, post_save) won't happen.

Model.objects.filter(pk=pk).update(key=value)

Bulk model functions won't happen signals.
