What are the best practices for validation in Ruby?

When validating in Ruby, it's important to use built-in validation methods, keep your models clean, and provide clear error messages.

Can you give me an example of a validation method?

Sure! You can use validates :name, presence: true to ensure that the name attribute is always present.

How can I customize error messages?

You can customize error messages by using the :message option, like this: validates :email, presence: { message: 'Email is required' }.

What about using custom validation methods?

You can define custom validation methods in your model. For example, validate :check_age where check_age is a method that contains your validation logic.
