Well, the example I used is a little simple for what I really need.

I have 4 models

Model A, Model B, Model C, and Model D

Everytime I update Model C, I have to update Model B
Everytime I update Model D, I have to update Model B

Everytime I update Model B, I have to update Model A, but this update
depends on "which" model has updated Model B. if Model C has updated
Model B I have to make some changes in Model A. But if Model D has
updated Model B I have to make differnts changes in Model A.

I think the simplest way to do this is to have an after_save callback on ModelC and ModelD.

Just call the method that will update ModelB and ModelA on the callbacks.

 

My problem is that I don't know how can I recognize which model has
updated Model B to "switch" between actions to update Model A
