CUSTOM VALIDATOR

# app/validators/url_format_validator.rb

# app/models/person.rb

# app/models/company.rb

> p = Person.create(name: 'Nome', email: 'email@example.org', personal_site: 'xunda')

(0.2ms) begin transaction => (...) (0.1ms) rollback transaction => (...)

> p.errors => #<ActiveModel::Errors:0x007fa06ff84618 @base=#<Person id: nil, name: "Nome", email: "email@example.org", personal_site: "xunda", created_at: nil, updated_at: nil>, @messages={:personal_site=>["Formato de site inválido"]}>>

# app/models/xunda.rb

if rails.too_old

end
