One of the most important parts of a development process is an application deployment. There are many tools developed to make this process easy and painless: from the simple inploy to a complex all-in-one chef-based solutions. My tool of choice is Capistrano, simple and incredibly flexible piece of software. Today I’m going to talk about some advanced Capistrano usage scenarios.

Not so far ago I have found a weird bug in the Open Source Ruby gem called composite_primary_keys, occurred when you specify :primary_key option for has_one or has_many association. There are two ways to get it fixed: submit an issue and wait till someone will work out this problem or fix it by yourself and then pull request to get the patch merged into the core. This is a great library and I use it in almost all my project, so I decided to help the author and fix this bug by myself. Here I will show you how to do that.

I use RSpec in all my projects. It’s really hard to overemphasize how helpful it is and how much easier becomes your life if you have good specs coverage. But its outstanding flexibility enables many ways to make your specs awful: horribly slow, over-bloated, even non-readable sometimes. I do not want to teach you BDD and RSpec here, but instead I will give you some ideas how to improve your specs quality and increase efficiency of your BDD workflow.
