String length validation for encrypted filed? #186

Closed shrkw closed 4 years ago

shrkw commented 4 years ago

Hi,

I want to validate length for encrypted filed. But standard way counts as byte length. So it does not work for string length.

validates :name, length: { maximum: 20 }

Do you have any idea for that?

Sorry, this is due to multi byte encoding. I can validate by name.force_encoding('utf-8').length.

Sorry to bother you.

Hello,

What is the purpose of validating the length of the field?

I think it is common use case though, I don't want to accept too long name input to users. I added client side length validation, and I wanted to add it on rails side too.
