rails-erd: Error: in routesplines, cannot find NORMAL edge

Howdy!

I’m trying to generate a graph in Rails 4. I can generate erd.dot, but I cannot generate a PDF. This is the output I get from rake erd

Loading application environment...
Loading code in search of Active Record models...
Generating Entity-Relationship Diagram for 24 models...

Graphviz produced errors. Verify it has support for filetype=pdf, or use filetype=dot.

The CoreText performance warning is repeated many times, but I’m not concerned about it (or maybe I should be?).

This is what I get when I run it verbosely dot -Tpdf -oERD.pdf -v erd.dot:

I had a look at the generated DOT. My graphviz version (2.36.0 (20140111.2315)) seg faults when there are multiple edges (=associations) between the same two nodes (=models). This may occur for example when a model tracks the modifying user with creator, updater and deleter associations.

Because rails-erd does not include any labels on the edges, I did not see the point in having multiple edges and removed them with the following patch:

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

This made the seg faults disappear, diagrams are generated fine again.

The patch fixed it for me too but now I get this error whenever I run my specs:

I’ve fixed it by scoping it to the development environment but it’s pretty clunky:

if Rails.env.development?
  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
end

If anyone has a better solution I’d love to hear it 😃

Should be fixed by #296 and in the v.1.6.0 release

rails-erd 1.5.2 dot 2.38.0

Still needed to apply this patch to make it work for User with invoice_address and correspondence_address as two links to the same model Address
