Simetro

The ultimate metro trip planner

It's your job to calculate the total number of stops between two Metro stations.

Step 1 - Connect the CSS file

Add a link tag to the head of layout.erb

Step 2 - Define a trip route

When visiting http://localhost:4567/trip in the browser, Sinatra responds with a 404.

Create a get route to respond to get requests to /trip

Create an instance variable @num_stops, and set it equal to the number of stops between the start and end stations.

1. get the index of the start station from `metro` at `params[:line]`
2. get the index of the end station from `metro` at `params[:line]` 3. Subtract them and set them equal to `@num_stops`

Note: Sinatra will not render numbers.

(If you're testing this out before creating the view)

get '/' do
  1 # must be "1"
end

Step 3 - Create a trip view

Create a new file in views/trip.erb. To show the trip results.

Bonus !

Allow the user to select any two stops, without selecting a line. Calculate the total number of stops between the two stations, and tell the user which station to switch lines at.
