Mongoid Dynamic Finder
Install this gem to use ActiveRecord type Dynamic Finders for your rails app on MongoDB.
gem install 'mongoid_dynamic_finder' in your gemfile. Don't forget to run Bundle install
You can now use the dynamic finders used in ActiveRecord.
For Artist model, here are a few examples :
Artist.create(:name => "Your Name") Artist.find_by_name("Your Name")
This would fetch the row within your collection for Artist named 'Your Name'. If not present, this would return 'nil'
Pass in two attributes in your finder.
Artist.find_by_name_and_title('Some Artist' , 'Mr.')
Use the 'first' and 'last' keywords
Artist.find_first_by_name('Van Gogh') Artist.find_last_by_name('Picasso') Artist.find_first_by_name_and_title("Muhammad Ali", "Boxer") Artist.find_last_by_name_and_title("Rocky Balboa", "Boxer")
Raise exceptions by using Bang ('!')
This would raise an exception while the rest would give out 'nil'.
