4# Querying

Records can be queried through the following methods:

Car.all # retrieves all saved records

Car.find car.id # find through its id
Car.find car # find through the record

Car.find_by_model 'F450' # find dynamically with a property
Car.find_by_model_and_price 'F450', 5000.00 # find dynamically with multiple properties

Car.where year: 2007, make: 'Chevrolet', model: 'F450' # find with a multiple parameters hash

Car.count # returns the amount of records in the database

Car.first # retrieves the first record in the database
Car.last # retrieves the last record in the database

Lazy querying is the default behavior now Yey!!

query = Jedi.where(age: 37).where(midi_chlorians: '4k')

query.first # #<Jedi:0x007f9df6cea478>
