Thank you for your report @abigoroth!
Do you have Graphviz and ruby-graphviz installed correctly? You might be able to test by using another gem that depends on Graphviz such as rails-erd.
If Graphvis and ruby-graphviz are installed correctly then it might be something odd about your rfq model. Is that project open source? I'd be happy to test aasm-diagram on that specific model if it is.
@Katee I have ruby graphiz, since I can generate diagram for Matsuda's stateful_enum gem . I also made a quick gem which act as middleware for AASM gem to generate diagram via stateful_enum. Here is DrawMe gem
@Katee I'm getting the exact same error. I can run rails-erd normally.
Since its a private repository I'm working on, I'm not allowed to share the model code here, but I can send it to you in pvt if you are willing to test it.
@fabianoarruda if you could share an example that would be very helpful. My email is hi@kate.io.
Same here.
I have 2 AASM models in my private repo. I made diagram for first one easily and got same error with second, a bit more complex one.
Actually got this fixed on my fork
Feel free to use it with gem 'aasm-diagram', github: 'Mayurifag/aasm-diagram', require: false, group: :development in your Gemfile, untill this issue getting fixed on its main repo.
@abigoroth it seems I didn't pass the "code review".
Here's the email thread I had about @Mayurifag's fork.
I really am happy to merge in a quick fix (especially if it includes tests!). I still need to figure out open source contributions at my new job.
Made a small fix/PR #5 to solve this. Sorry for no tests, but wasn't exactly straight-forward to try and write specs for this (a lot of aasm models would have to be stubbed/created)
