Jquery Full Calendar with RubyOnRails
Mar 29th
Cross Posted from http://vinsol.com/blog
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.
Update: Added recurring events functionality to the demo app.
Feel free to give your valuable feedback. I hope you will find this useful.

Printing large image diagrams generated by RailRoad
Mar 23rd
I use RailRoad for generating Ruby on Rails diagrams, but always wish I could print those diagrams. Generally diagrams are too big to print on a single A4 size paper and I didn’t find any tool to print larger images in parts so that I can join them. If I print the image generated by RailRoad on single page, it of no use as it is hardly readable.
Fortunately, two days ago I found something which resolved this issue. It is a linux command and print a particular image on four pages. Here is that command:
lp -o scaling=200 models.png
Tip: Open DB shell/console from rails root dir
Jan 29th
Just a quick tip you might be using this already.
If you guys want to open your app’s DB shell. Then you can use rails utility ‘dbconsole’ by issuing “script/dbconsole” from rails root directory.
It will ask for DB password, and open your db shell.
If you use sake, you may like following sake task:
desc 'Launches the database shell using the values defined in config/database.yml'
task 'db:shell', :needs => [ 'environment' ] do
config = ActiveRecord::Base.configurations[(RAILS_ENV or "development")]
command = ""
case config["adapter"]
when "mysql" then
(command << "mysql ")
(command << "--host=#{(config["host"] or "localhost")} ")
(command << "--port=#{(config["port"] or 3306)} ")
(command << "--user=#{(config["username"] or "root")} ")
(command << "--password=#{(config["password"] or "")} ")
(command << config["database"])
when "postgresql" then
puts("You should consider switching to MySQL or get off your butt and submit a patch")
else
(command << "echo Unsupported database adapter: #{config["adapter"]}")
end
system(command)
end
