Dynamic Finders in Rails
Ruby on Rails makes it easy to find a specific record in a table based off some fields. With Active Record you can search a model easily by the following:
User.find_by(first_name: 'Sunny', last_name: 'Mistry')
A cool feature that Rails provides is dynamically generating finder methods for every field on a table.
User.find_by_first_name('Sunny')
An even crazier thing is you can do this for multiple fields!
User.find_by_first_name_and_last_name('Sunny', 'Mistry')
This can go on for as many attributes as you like. I’m not really sure why anyone would do this but it is interesting.
