UniqueViolation: Error in Gallery edits (Rails 5.2.1) about actiontext HOT 7 CLOSED

The following method ended up being the issue:

# active_storage/attached/many.rb

module ActiveStorage
  class Attached::Many < Attached

    def attach(*attachables)
      attachables.flatten.collect do |attachable|
        if record.new_record?
          attachments.build(record: record, blob: create_blob_from(attachable))
        else
          attachments.create!(record: record, blob: create_blob_from(attachable))
        end
      end
    end

  end
end

It seems to work if you just add an attachments.exists? query before attachments.create! to prevent a violates unique index error when it tries to create the same attachment twice.

It looks like this entire part of ActiveStorage was totally rewritten for Rails 6, so now I understand why there's no Rails 5.2 support :-)

Excited for ActionText's official launch in Rails 6! It's truly an awesome tool.

Yes it does @javan

The only Rails 5.2.1 specific change (relevant to this) is to simply remove the image transforms from _blob.html.erb: <%= image_tag blob.representation({}) %>

Does <%= image_tag blob %> work?

Cool, you can probably use the older representation API for Rails 5.2.1 support. See dec130a.

Thanks @javan! Our main issue isn't old representation API, though, it's the violates unique constraint issue. Any thoughts on that? Thanks!

That seems like a general ActiveStorage issue… @georgeclaghorn?

Thanks @wxmn, I was looking at the exact same situation, issue, and solution. Nice to have a second confirmation.
