TLDR
HTML5 provides instant validation trough input: type and required tags. Ruby on Rails uses Active Record Validations to ensure the information in the database is consistent and adds an extra security layer to our deployed applications. In this quick guide, we will validate a table with name, email, and password: fields used when a user’s login feature is required. We use the presence validator whenever we need the input to exist. We also use the length validator to a 255 maximum to avoid database overflowing.via the TL;DR App
