Jquery Full Calendar with Ruby on Rails

Contrary to popular belief, working on a client project gives us a generous margin of creativity and explore innovative solutions. Take the example of a recent project I was working on. The client required a collaboration-based calendar module for their application similar to Google Calendar. Initially we started developing it from scratch , but then, we found an awesome Jquery plugin.

"FullCalendar" provides a full-sized, drag & drop calendar. It uses AJAX to fetch events on-the-fly for each month. It also supports an intuitive interface to manage events that spans over multiple days or weeks. It is visually customizable and exposes hooks for user-triggered events (like clicking or dragging an event).

I decided to give it a try and utilize its hooks for user triggered events within our Rails application. This small effort resulted in a barebone Rails app that might provide a good base for your project which require calendar, scheduling or appointment features. I called it fullcalendar_rails and it is now available on github with a working demo at http://fullcalendar.vinsol.com.

Feel free to give your valuable feedback. I hope you will find this useful.

Update: On popular demand, I have added recurring events functionality with daily, weekly and monthly frequencies. It also allows for exceptions to recurring events including delete and edit features.

Ruby on Rails Caching And JavaScript Techniques

Cross posted from darthsid

While implementing caching in a recent rails project I came across some typical caching issues. In a lot of pages the content is same for all users but certain components in them have user specific actions. As an example, I have a page listing all public messages that users have posted(similar to the public timeline in twitter) but actions on those messages are user specific(eg: only owner or admin can delete a message). Also, most of these actions use ajax and the rails authenticity token in them also gets cached resulting in subsequent failures if the session changes. Another issue was that the timestamps in most pages is fuzzy and they become irrelevant if a page gets cached for too long. I could have created separate caches for each user but if the user base really grows managing the caches would become a nightmare and that would still not solve the authenticity token and the timestamp problem. The simplest solution was to use JavaScript, more specifically jQuery.
