И про отдельную таблицу тоже?
Вообще про все:
This is a contrived example, but it gets the point across. With signals, we have to spread the logic across three different files. Worse, the standard for putting signals in a signals module is not always followed, especially in older code bases. Simply finding where the signals are defined and connected can be a challenge. The example without signals is not only less code, but far easier to read, understand, and test. You can see all the side-effects of Pizza model creation, simply by reading the code of the Pizza model.
