Calendars in rails are a solved problem, right? But oddly I couldn’t find one out of the 80 “calendar + ruby” listed on github with a weekly view. So I decided to build my own and I’m happy to announce my first plugin: WeeklyBuilder. The builder creates a horizontal scrolling calendar, mapping events for each day of the week. The layout is fluid CSS and the hours can be switched from business hours to 24 hours.
