Unit testing in Rails - state of database when test fail

After some code refactoring some tests failed. Ok, that means something in code is wrong and that is great thing to know. Usually it is enough easy to check the test case where the problem occured and fix code in model. However my yesterday problem was a bit complicated because the action that should change create and change objects from dependant models obviously didn't do that in in the way it should. It would be easiest method to find where problem is to check the state of database just before test failed.

Creating PDF documents with tables in Ruby, Rails

I started to use "Ruby FPDF":http://zeropluszero.com/software/fpdf/ to create PDF documents from our new Rails application "MojGost.com":http://www.mojgost.com. Ruby FPFD like it's "PHP counterpart":http://www.fpdf.org/ does not have methods for creating tables. However, there are many examples and scripts available and that allowed me to quickly write small Ruby module which adds few methods for easy table creation.

Overriding class methods in Ruby

Class methods in Ruby are methods that work without being tied to any particular object (Java and PHP5 have static methods for similiar purpose). Class methods are distinguished from instance methods by placing the class name and a period in front of the method name. One thing that may not be obvious if you want to inherit class method is how to call equally named class method from parent class.
