Oops - sorry - missed a small, but very important bit - You need to
roll out the list as arguments. Ordinarily, the usage of add() would
be:
data.rims.add(1,3,7,9)
but since you already have a list, you use:
data.rims.add(*req.POST.getlist('rims'))
Sorry for leading you astray.

This is effectively the same solution, but rolled out in code.

I'm not sure I understand what you're trying to do here. The save()
method on an instance doesn't affect the m2m relations. However, there
are other mechanisms, such as saving a web form, that will modify m2m
forms.
How are you updating the Previsione instances? Using a web form?
Programmatically? Some other way?

In short, you can't. However, this doesn't stop you from adding a
different method to your model that has the side effect of calling
save.
