Reading AR validations at runtime

Rails
1

Does anyone, by chance, know how to obtain a list of all the defined
activerecord validations at runtime?

In other words, I’d like to query a model for all the fields that are
unique, or required.

I found this: read_inheritable_attribute(:validate), but it seems to be
deprecated in later versions of rails. Thanks so much for any insight.
