I’d like to start with a disclaimer. I have been developing websites using Django for 3 years now and it’s no secret that I like Django. I wrote an open-source app for it and I have started sending patches to Django. I have however written this article to be as unbiased as possible and there’s plenty of compliments (and criticism) to both frameworks. Six months ago I joined a project at my University using Ruby on Rails and have been working with it since then. The first thing I did was to look for for reviews and comparisons between the two frameworks and I remember being frustrated. Most of them were a little shallow and compared them on a higher level while I was looking for answers to questions like ‘how are database migrations handled by both?’ , ‘what are the differences on the template syntax?’

10 Most Common Rails Programming Mistakes. Ruby on Rails (“Rails”) is a popular open source framework, based on the Ruby programming language that strives to simplify and streamline the web application development process. Rails is built on the principle of convention over configuration. Simply put, this means that, by default, Rails assumes that its expert developers will follow “standard” best practice conventions (for things like naming, code structure, and so on) and, if you do, things will work for you “auto-magically” without your needing to specify these details. While this paradigm has its advantages, it is also not without its pitfalls. Most notably, the “magic” that happens behind the scenes in the framework can sometimes lead to headfakes, confusion, and “what the heck is going on?” Types of problems. It can also have undesirable ramifications with regard to security and performance.
Accordingly, while Rails is easy to use, it is also not hard to misuse. Common Mistake #1: Putting too much logic in the controller.
Rails app deployment. OCRA: One-Click Ruby Application Builder. I recently mentioned the fact that RubyScript2Exe 0.5.3 doesn't play well with recent versions of RubyGems. At the end of that post I mentioned that there are alternatives emerging for creating executables from your Ruby code, including Lars Christensen's OCRA, the One-Click Ruby Application Builder. I've had a chance to take OCRA for a short test drive and it looks promising. Like Erik Veenstra's RubyScript2Exe, OCRA lets you "compile" your ruby code into an EXE file that you can distribute to others, without requiring that the users have Ruby installed on their PCs. To quote the OCRA page: The executable is a self-extracting, self-running executable that contains the Ruby interpreter, your source code and any additionally needed ruby libraries or DLL.
OCRA can be installed via RubyGems: open a console window and type: gem install ocra It's also available from the RubyForge page. The syntax to compile a script is... ocra.rb [option] your/script.rb ocra.rb myscript.rbw Thanks for stopping by!
