Has_many ... through Association

Hi,

Let's say I have 4 models: City, Line, Direction, Message
City ha many lines
lines has many directions
and direction has many message

Tell me if what's next is correct
Line as many messages through line
City has many messages throufh line

Is this possible especially for the city model? Is this the correct way
to access messages from city?
