Input Validators
Attach input validation rules to columns!
Overview
The validators provide a way to attach input validation logic to columns. The columns themselves already provide basic validation (making sure strings are strings, integers are integers, etc…) but these classes allow for more detailed rules.
It’s important to understand that validators only apply to client input, which means that input validation is only enforced by appropriate endpoints. If you inject a model into a function of your own and execute a save operation with it, validators will NOT be checked.
