-:ballot_box_with_check: `validators` **This is an really useful feature!** You can define a function that evaluates whether if the value of a field  fulfills some requirements. If at any moment an invalid value was to be assigned, it would not pass the validation and that modification would never happen. Not in the local object, neither in the database.
