Thank you very much for the answer, but I'm still having issues.
I've declared the funcion on the class that will be monitored for changing,
let's say, MyModelA. And then, in the view that controls the changes for
objects of the model I want to change, in this case MyModelB, I've used the
post_save.connect, just as you told me to.
But whe I try to do any sanity checks (i.e print('test')) in the
post_save_function, I end up with nothing. I don't get any error messages,
but the function is just not being called when I issue a save for MyModelA.
I've tried relocating the connect code in the views.py archive, but nothing
seems to make it work. How can I proceed?
