RailRoad: Generate model and controller diagrams for Rails applications

By Peter Cooper / April 11, 2007


RailRoad is a Ruby application that generates model or controller diagrams for Ruby on Rails applications. It analyzes properties, inheritance, model associations, and so forth, and produces a graph description in the DOT language which can then be handled with third-party tools. The official site features several compelling examples, including model and controller maps of the Typo blogging system (as seen above).

    Wow, this tool is awesome.

    I've always been jealous at teammates who were using tools to print out their model schemas =P.

  2. Max says:

    Wow, I really like this tool, especially for visualizing how complex some applications are and what mess I have created in older projects ;)

  3. Daniel Fischer says:

    This is certainly quite interesting, I wonder how I can find use for it.
