cannot find erd.pdf file

[manish310794]

I installed graphviz and the gem as per the instructions. I then cd into my project.
proj$ bundle exec erd

It says

diagram saved to 'erd.pdf'

But I cannot find any such file inside my project directory.

[kerrizor]

Hmmm... assuming it ran successfully, it should be saving the file into the same spot where you ran the erd command. Can you share the output of running the command, to be sure?

[manish310794]

Here is the output of running the command

vagrant@canvasvmfrommybox:/vagrant/canvas$ bundle exec erd

Hmmm... I don't know! Do you have graphviz installed properly? Also, try running bundle exec erd --filetype=dot and see if you can at least get an erd.dot file generated. Finally, and this may seem basic, but I've done it -- do you have write access to the directory you're working in?

Thanks for reporting this.. if we can solve this, we can add a bit more polish and "customer friendly" warnings if we detect something going wrong. ❤️

[manish310794]

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.

[phikes]

The same thing is happening for me (exactly). I am using GraphViz version 2.38.0. I also get the segfault.

[kerrizor]

@manish310794 @phikes well dang. I'm on GraphViz 2.38.0 as well. Can either of you confirm that you're using the latest version of the gem (1.4.7)? The only other thing I can think of is that sinze you're getting a seg fault when you're invoking dot -- which is graphviz -- perhaps trying removing it and reinstalling it. Hopefully that's easy for you; I use HomeBrew for this, which makes it pretty simple.

[phikes]

I am on brew as well and reinstalled already :/. I am on version 1.1.0 though. I will check with the latest version.

[phikes]

I checked with version 1.4.7, no luck either :/. Let me know if I can do anything else.

[kerrizor]

Would any of the solutions in #160 or #12 work?

[phikes]

I tried the second one and it did not work unfortunately.

[hjoseph96]

Having this problem also.

Running into it as well on El Capitan

I'm also seeing this problem (El Capitan here, too). I ran dot -Tpdf erd.dot -o erd.pdf -v (with the verbose flag) and got this output, in case it's helpful:

I'm not sure this actually provides any more useful information beyond the fact that it segfaulted -- I don't really know how to interpret any of these messages. Also wanted to note that I had no problems generating diagrams with RailRoady, which also uses graphviz in a similar way.

[mattvanhorn]

I'm also getting this same segfault on version 1.5.0 with GraphViz 2.38.0

[mcfadden]

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"

[kerrizor]

@mcfadden that's an interesting possibility, a timeout or error of some kind from the size.. out of curiosity, how many models in your app?

[mcfadden]

I'm not so sure about a Timeout, only because I get the error instantly when running dot -Tpdf erd.dot -o erd.pdf, but some other error resulting from that is quite likely.

The app I ran this against has ~125 models.

[kerrizor]

Hmmm yeah, its probably not size then; I've run this against apps with multiple 💯 s of models.

[adaam2]

Is there any update on this?

[kerrizor]

Similar reports in #200 and #201

Are you running into this, @adaam2 ?

[adaam2]

Got around this issue by generating the .dot file first and that seemed to remedy it

[satyagrahi]

Not getting pdf. Just installed it today so have latest versions. Can get dot file generated, but not pdf (even after creating the dot). Not able to find it anywhere on the system (looked everywhere just in case). On MacOS Sierra (10.12.5) and .rvm/gems/ruby-1.9.3-p545/gems/rails-erd-1.5.2

Converting the dot file generates a segmentation fault:

[1]    5456 segmentation fault  dot -Tpdf erd.dot -o erd.pdf -v

[kerrizor]

Oh. Derp. Do you have "Arial BoldMT" installed? We might not be handling a fallback case correctly here..

[satyagrahi]

I have "Arial Rounded MT Bold" installed. Can't find "Arial BoldMT" on the web.

[andrewpatterson3001]

I am also unable to generate a PDF from the dot and I do not have Arial BoldMT installed.

[mjparrott]

Also having this issue where there is no erd.pdf in sight. Tried installing Arial BoldMT from a couple sources but still didn't work.

[brianbolnick]

Having the same problem here, lots of models in my case too. Would love an update to this!

[kerrizor]

I think the missing font is a red herring; something about our dot output is triggering a segfault.

Anyone able to share a DOT that is causing this?

[eronisko]

Hi, sharing my DOT file.
https://drive.google.com/open?id=1rymB5dBTYJqMk5RLZf8UQQpqVAi9i-Oa

Note that it's made out of 150 models. Here's the code: slovensko-digital/harvester.ecosystem#23

[pedros007]

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

[mustela]

Having the same problem here, Ive tried all the different approaches mentioned here, but with same results.

[mustela]

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

[rlugge]

I'm getting the same error. I can generate the dotfile, but if I try to generate a PDF it just silently fails, telling me the PDF was generated.

erd --inheritance --direct --attributes=foreign_keys,content works.

Also, if I run rails c and then:

(ActiveRecord::Base.connection.tables - %w[schema_migrations]).each do |table|
  table.classify.constantize rescue nil
end

RailsERD::Diagram::Graphviz.create

That also works

@kerrizor

Had same issue. Verified that bundle exec erd --filetype=dot produced the dot file output correctly, which led to a seg fault when parsing with the dot command (no matter the type of output). Found that neato would produce output with the same dot file. Upon further investigation, found that the dot file provided had duplicated edges, likeso:

  m_Address -> m_Company [arrowhead = "normal", arrowtail = "none", weight = "5"];
  m_Address -> m_Company [arrowhead = "normal", arrowtail = "none", weight = "5"];

Modifying the dot file to remove the duplicate edges allowed the dot command to run successfully and produce the output.

[kerrizor]

It appears that Graphviz segfaults when trying to draw multiple edges between the same 2 nodes. #70

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