With Ruby 3.0 validator produces "ArgumentError: wrong number of arguments (given 3, expected 1..2)"

[vtamara]

The regression tests of an open source rails engine called sip, that uses paperclip, work good with Ruby 2.7 as can be seen at:
https://travis-ci.org/github/pasosdeJesus/sip/jobs/760216853

However with Ruby 3.0 the following errors appear (as can be seen at https://travis-ci.org/github/pasosdeJesus/sip/jobs/760216854#L976):

1) Error:

Sip::AnexoTest#test_no_valido_1:

ArgumentError: wrong number of arguments (given 3, expected 1..2)

    /home/travis/build/pasosdeJesus/sip/vendor/bundle/ruby/3.0.0/gems/activemodel-6.1.3/lib/active_model/errors.rb:404:in `add'

    /home/travis/build/pasosdeJesus/sip/vendor/bundle/ruby/3.0.0/gems/paperclip-6.1.0/lib/paperclip/validators/attachment_presence_validator.rb:8:in `validate_each'
...

and

2) Error:

Sip::AnexoTest#test_no_valido_2:

ArgumentError: wrong number of arguments (given 3, expected 1..2)

    /home/travis/build/pasosdeJesus/sip/vendor/bundle/ruby/3.0.0/gems/activemodel-6.1.3/lib/active_model/errors.rb:404:in `add'

    /home/travis/build/pasosdeJesus/sip/vendor/bundle/ruby/3.0.0/gems/paperclip-6.1.0/lib/paperclip/validators/attachment_presence_validator.rb:8:in `validate_each'
...

Both are related to expressions anexo.valid? where anexo is amodel with a paperclip attachment. Both use the validator AttachmetntPresenceValidator that includes the statement producing the error:

def validate_each(record, attribute, value)
    if record.send("#{attribute}_file_name").blank?
      record.errors.add(attribute, :blank, *options)
    end
end

I'm hitting this same issue with Ruby 3.1.0. Any ETA on the fix?

[vtamara]

I switch to kt-paperclip

[joshuapinter]

I concur. I switched to kt-paperclip and it's the way to go for Ruby 3+ support as well as ongoing maintenance. We had to update our WebMock and specs a bit as there were some changes in how files are requested from AWS in kt-paperclip but otherwise, seamless transition.

The thing is that I also need 'paperclip-optimizer' which seems that install original paperclip
I installed kt-paperclip-optimizer, but it also install in the background original paperclip gem, which causes that error:

ArgumentError:
       wrong number of arguments (given 3, expected 1..2

That's a part of my Gemfile.lock where is installed paperclip

    paperclip (6.1.0)
      activemodel (>= 4.2.0)
      activesupport (>= 4.2.0)
      mime-types
      mimemagic (~> 0.3.0)
      terrapin (~> 0.6.0)
    paperclip-optimizer (2.0.0)
      image_optim (~> 0.19)
      paperclip (>= 3.4)

Someone knows how to avoid that dependency and just keep installed kt-paperclip¿?

[joshuapinter]

@maxvlc Can you not just fork the project and update the dependency in the .gemspec file?

@joshuapinter Yep, that's the point, fork the gem and keep it on our project.
