Rewrite project from Zend Framework to Rails

About five months ago, I tied up with the zend framework and moved onto rails. Then he began to rewrite his project www.okinfo.ru . Now it is already finished and sloccount showed that the number of lines in the project decreased from 15,000 to 4,000. My familiar php developers asked for a success story and eventually this article was born. In it, I will describe how it was, as well as talk a little about my transition to ruby.

Prehistory

Having worked as the main developer of www.starlook.ru for about two years, I reached a point where you understand that it is time to move on. The architecture of the application is well-established, scaling is inherent, the code as a whole is fine and in general the whole development process was clear and debugged. In fact, we continued to increase the functionality and maintain already written. At this time for interest, I began to look closely at django and rails. Despite the fact that the python as a language I liked, but that django was not impressed. And with the rails and cut the situation was completely different. It can be called love at first sight. And literally after a month of study, a letter came to My Circle offering a vacancy for a ruby ​​developer, although it was an accident, since sending for some reason thought that I know ruby. In general, I decided that this was fate, and after passing a bunch of interviews, they still took me to chop for a new place.

What for?

After getting acquainted with the rails, it was very difficult to continue writing a project on ZF, too much had to be done by hand and practically for each task (tags, trees, deploy, migrations, etc.) to write our own solutions. Given that there is not much free time on the project, it was decided to rewrite it, killing two birds with one stone. Firstly, to simplify your development and support, and secondly, to tighten the knowledge of the relevant technologies.
