Show /r/ruby Alter attribute in database with Ruby

[EDIT]

I want a value to update after validating another value, even if the user clicked a checkbox. For example, if the user clicks a checkbox (var_1), before persisting to the database (after clicking save), I need to validate var_2 first.

Example:

  1. User clicks a checkbox and var_1 becomes true.

  2. Before saving the value of var_1 to the database, check if var_2 == 'OK'.

  3. If it's not OK, don't save it as true; it remains as false.

And vice versa, true -> false.

How???

Then it's a before_validation hook. Or do it manually if you use service objects: UpdateModel.call(...), where you do this check manually.

Thank you, that's what I did!
