Help with railroad

[Rodrigo Ruiz]

Can anyone help me install railroad gem?

What I need is a simple class diagram of my rails website. Not necessarily with railroad (if you know any other software, for mac, that works).

The website is http://railroad.rubyforge.org/

I couldn't find any explanation on how to install it.

Thank you,

Rodrigo

Have you tried running the command "gem install railroad"?
What result does that give you?

I am happy using rails erd:

If needed, not only the model diagrams, use http://github.com/preston/railroady.

I did manage to install it with 'install railroad gem', problem is that when I run any command like 'railroad -a -i -M | dot -Tpng > doc/models.png' it doesn't work, I get this:

do you install the graphviz? is needed for generate the diagrams, linux or mac your OS?

[Leoncio Caminha]

other mode for generate models in rails is http://rails-erd.rubyforge.org/, very simple and require too graphviz, much easer

Ya, but I need both, models and controllers diagram, and yes I did install graphviz (manually though, not through command line)

and I did manage to generate the controllers and models with their methods, but not instance variable or inheritance connections.
