Models

Models extend Backbone.Model if no other information is given

Stops

• Extends: Collection
• Just a collection of stops

Line

• Arguments: line id, colours (foreground, background)
• Contains a collection of stops
• Fetches stops from the server using paths like /lines/:line_id/stops

Vehicle

• Arguments: journey id, vehicle type
• Takes trip information in the following format: {destX: 123, destY: 123, time: 123}
• Trips have a custom setter-method which sets the this.time and this.destination attributes, otherwise it wouldn't be possible to have separate change events for time and destination
• Receives updates from the websocket server and triggers events for the view.

Views

Line

• Contains a canvas for Raphael and info like end stations and line name
• Iterates through the Line collection to find typical travel times and calculates relative pixel distances
• NEEDS:
  • In the line model:
    • id, name, totalTime, stops
  • In the stop model:
    • time
• Currently renders it self when, and only when, the stops collection in the line model fires the reset event.

Stop

• Draws itself as a dot and a text.
• Params: needs a shape and a reference to its paper/canvas

Vehicle

• Reacts to events in the Vehicle model:
  • change:time: if vehicle is moving, change animation to reflect new time. Otherwise, do nothing?
  • trainLeftStation: starts the vehicle moving towards the current destination.

Rake tasks
