Hi,
I have 3 model :
User
$id
$name
Car
$id
$name
Transaction
$id
$user (belong to user)
$car (has many car)
I want to get list of user who buy the car with name X
I did sql query like
select user., transaction. from transaction, user, car where car.name = ‘X’ and transaction.car_id = car.id and user.id = transaction.user_id ;
But how to convert that query into ActiveRecord ?
