Installation

smashing install e0ffa81df3e25171f993b1bc40c91b18

or

• Copy cta_bus_widget.coffee, cta_bus_widget.html, cta_bus_widget.scss into widgets/cta_bus_widget/
• Copy cta_bus_widget.rb int jobs/

Usage

In cta_bus_widget.rb replace the following:

• YOUR_CTA_BUS_API_KEY with the API key you get at https://www.transitchicago.com/developers/bustracker/
• YOUR_STOP_NUMBERS with a comma-separated list of a maximim of 10 stop numbers that can be found by going to https://www.transitchicago.com/schedules/ and looking up your route(s). Note that stop numbers are different for opposite directions.

Add the widget to your dashboard layout like this:

<li data-row="1" data-col="1" data-sizex="3" data-sizey="1">
    <div data-id="cta_bus_widget" data-view="CTABusWidget"></div>
</li>

A width of either 2 or 3 usually looks good. If a height of 2 or more is used, the max variable in cta_bus_widget.rb can be changed to increase the number of results to fill the space.
