Help with railroad

Rails
1

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
GitHub - preston/railroady: Ruby on Rails 3/4/5 model and controller UML class diagram generator. (`brew/port/apt-get install graphviz` before use!).

Ya, actually I do need a class diagram for controllers and models.
How can I use that railroady?

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

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:

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.
