rails-erd: cannot find erd.pdf file

I had the same problems reported above: bundle exec erd would print diagram saved to 'erd.pdf', but no such file was created to disk. I found a fix that works for me:

1. Run bundle exec erd --filetype=dot
2. Edit erd.dot and delete the line concentrate = "true";
3. Run dot -v -Tpdf erd.dot -o erd.pdf
4. Profit!

If I didn’t comment out concentrate = "true";, GraphViz would Segmentation fault: 11 on both Debian with GraphViz installed via apt and Mac OSX with GraphViz installed via brew.

Alternatively, I can generate erd.pdf if I create config/initializers/erd.rb with the patch recommended here from #70 :

require 'rails_erd/domain/relationship'

module RailsERD
  class Domain
    class Relationship
      class << self
        private

        def association_identity(association)
          Set[association_owner(association), association_target(association)]
        end
      end
    end
  end
end

Version info:

$ dot -V dot - graphviz version 2.38.0 (20140413.2041) $ erd --version RailsERD 1.5.2

bundle exec erd --filetype=dot worked. It generated the erd.dot file. But I am not able to convert this file to pdf using dot -Tpdf erd.dot -o erd.pdf. It shows Segmentation fault (core dumped) message.

Having this problem also.

Running into it as well on El Capitan

$ dot -v

Actually this erd --inheritance --direct --attributes=foreign_keys,content is working…

I’m getting this as well on 1.5.0 with GraphViz 2.38.0 I think this is due to the large number of models as it works when I limit it to just a handful of models in my app. Ex:

bundle exec rake erd only="Model1,Model2,Model3"
