Rails Best Practices | Use query attribute

Do you always check if ActiveRecord's attributes exist or not by nil?, blank? or present? ? Don't do that again, rails provides a cleaner way by query attribute Bad Smell <% if @user.login.blank? %> <%= link_to 'login', new_session_path %> <% end %> <% if @user.login.present? %> <%= @user.login %> <% end %> It's not bad, but rails provides a cleaner way, we should use query attributes to make code
