A different take on validation using the dry-validation gem

Posted on March 10, 2019May 18, 2022

If you are using Rails and you find yourself fighting validations more often than you would like to, then you should consider watching my talk I gave at the London Ruby User Group this February about on dry-validation.

I will present the API surface which uses a schema based declarative approach and I will compare it with the classic ActiveModel::Validations approach in Rails for a simple but not trivial example.

You can find the talk here
