-For every field (also known as an attribute) you define in your table, Active Record provides a finder method. If you have a field called `first_name` on your `Client` model for example, you get `find_by_first_name` and `find_all_by_first_name` for free from Active Record. If you have a `locked` field on the `Client` model, you also get `find_by_locked` and `find_all_by_locked` methods.
