paper_trail doesn't seem to work with acts-as-taggable-on

[aaronjensen]

paper_trail tries to set the fake attributes that acts-as-taggable-on uses resulting in:

ActiveModel::MissingAttributeError: can't write unknown attribute `tag_list'

Can you please provide more detailed information on how to reproduce this? Just attempted to and was unable to do so.

[aaronjensen]

Sure, sorry. This would need a test_models table.

class TestModel < ActiveRecord::Base
  acts_as_taggable
  has_paper_trail
end

describe TestModel do
  it "is broken" do
    PaperTrail.enabled = true
    model = TestModel.new tag_list: 'foo, bar'
    model.save!

    model.update_attributes(tag_list: 'bar, baz')
  end
end

I'm not sure if these specific versions are necessary or not, but I'm on rails 4 and ruby 2, so this is an excerpt from my Gemfile:

ruby '2.0.0'

gem 'rails', '4.0.0.rc1'
# Rails 4 support, pending release of 2.4.1
gem 'acts-as-taggable-on', github: 'mbleigh/acts-as-taggable-on'
# Rails 4 support
gem 'paper_trail', github: 'airblade/paper_trail', ref: 'rails4'

I'm also seeing this

I believe this fix only made it into the master branch, is it possible to get it into the rails4 branch as well? Thanks!

@speedmanly - Just merged it into the rails4 branch, you should be good to go.

@fullbridge-batkins Thanks so much!!

Seems paper_trail doesn't track tag list changes under Rails 5. I think it may have something to do with API changes, as per this issue.

Anybody else experiencing this?

Hi Dhruv, I was just discussing this with someone on S.O. (https://stackoverflow.com/questions/45156752/rails-how-to-enable-papertrail-auditing-for-tags)

Two suggestions: 1. use Version Metatadata (github.com/airblade/paper_trail#4c-storing-metadata) 2. use Association Tracking (github.com/airblade/paper_trail#4b-associations)

I haven't heard back from them if they tried either.
