Get extra attibutes from the model for the digraph export

[froderik]

We use this gem to generate a dot file that we pick up with ruby_graphviz to show in a browser. Now we wanted to make nodes clickable and found out that the fastest path was to get more information into the dot file. In our case the URL and target attributes but the proposed solution can be used for any attribute.

Interesting! Could you add a test case please? Also, I'm sure you have seen this already, but if your method hits any non-hydrated attributes, this will be an n+1 select situation. We might want to add a warning in the readme. Thanks for the submission!

Yes! I had a look at specs but it turned out I needed to install MySQL to run them. Then I found tests.sh and tried the appraisal thing with only sqlite and then I get The git source https://github.com/matthuhiggins/foreigner.git is not yet checked out and run bundle install which I obviously already did. Any idea about how to move forward?

Hi @froderik, I recently encountered this very same problem so I thought I'd share a work-around if this is still an issue for you or anyone else viewing this. What worked for me was:

brew install mysql
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents 
brew services mysql start
bundle install
bundle exec rake spec

I am still not able to get the test matrix to run by executing the shell script ./tests.sh and as weird as it sounds, the steps above don't work when executed inside a tmux pane. Anyhow, I hope this helps!

[froderik]

Aha - may be that I ran inside tmux actually. Good catch.

I will probably not get the time to work anymore on this now anyway so the monkey patch I added to our project will stay for a while. (As a consultant I am switching customer as of monday!)

Please re-open when all tests pass.
