Rails: Rake gives Zeitwerk error when mentioning one model class in another

rubyonrails-talk

Thanks for your condolences. But programming is a good way to take my mind off all the horrible responsibilities etc… :slight_smile:

Ok, yes same issue with seed.rb containing only

foo = Comment `

And Comment.rb only containing

class Comment < ApplicationRecord 
#commented out code.... 
end

As for what’s loading AttachmentHelpers and JsonHelpers they were being loaded by my user model but I think I’ve managed to get the relevant code commented out now.

Ohh, and I’ve cut down application_record.rb to just

class ApplicationRecord < ActiveRecord::Base

end

And the User model down to just

class User < ApplicationRecord
end

And once I’ve done that the result of running db:seed is still the same error with the full result below (I deleted my above reply because I forgot to turn off spring when running it as I did here).

Finally got it!

So I have a rake task defined as follows:

require 'rexml/document'
include REXML

namespace :db do
  desc "Delete all unconfirmed users after 1 day"
  task :import_journal_abbrevs => :environment do
 ...
end

The important thing here is that I’m loading REXML (maybe I’m doing it wrong but I thought this was what I needed to do since I didn’t really want to load the gem all the time for this one rake task). If I comment that out, even though this task isn’t directly being run, no error.

What appears to be going on is that REXML has an internal class Comment. (I figured this out by just going into my gems directory and doing a grep for Comment in all .rb files).

Ahh, and now I see what I should have done! I needed to write this code as

require 'rexml/document'

namespace :db do
  desc "Delete all unconfirmed users after 1 day"
  task :import_journal_abbrevs => :environment do
    include REXML
...
end

Thanks SOO much! Man these loading bugs are hard to track down.

Wow. I have been following along this whole time, completely baffled why this was having such an effect. What an excellent find. If you require ‘rexml/document’. can you get away with referencing any of the methods it contains long-hand inside your rake task? Also, it’s important to remember that Rake tasks are pretty much like wide-open IRB consoles, they have none of the namespacing that a class would have. What I mean by this is instead of including REXML and then calling method whatever from it, you could use a complete namespaced call to that method:

REXML::Document.new(...).whatever

That way you wouldn’t have to expand those methods in the local context, and they might stay isolated from the rest of your code.

Best wishes, and sorry for your loss.

Awesome!!!

So, I believe this issue is not exactly related to autoloading. This script reproduces:

module M
  class Comment
  end
end

include M

class Comment < String # superclass mismatch for class Comment
end

I suspect this is either a bug in Ruby, or perhaps some quirk of the special top-level main object. The top-level include is not even the usual Module#include, it is a different method.

I’ll followup if I connect all the dots.
