Need to add ActiveSupport as dependency

[theRealNG]

#ruby version 2.4.3
active_record version ( 5.1.4 )
paper_trail version (8.1.2)

I'm working on an application not based on rails but I am using active record. I noticed that when I open irb and require 'paper_trail', I am getting the following error

NoMethodError: undefined method `squish' for #<String:0x00007f8710b395e0>

We are using squish method that is defined in active_support:
https://github.com/rails/rails/blob/cfb1e4dfd8813d3d5c75a15a750b3c53eebdea65/activesupport/lib/active_support/core_ext/string/filters.rb#L21

Therefore we should add active_support to dependency so that we don't run into this error.

Steps to reproduce the error:
Clone this repo:
https://github.com/theRealNG/paper_trail_active_support_dependency

1. Open irb terminal
2. Type require "paper_trail" and you will get that squish is not defined.

Hi Ng. Sorry, I don't understand your setup. The paper_trail gem depends on activerecord which in turn depends on activesupport. Therefore, AS already is a (transitive) dependency of PT. What am I missing?

I'm checking out your repo now ..

I'm checking out your repo now ..

We need to add some requires, don't we?

I'm running into undefined method when I'm trying to require the paper_trail gem itself.

I think to use the squish method which is defined in the active_support you need to explicitly add it as dependency. ( Not 100% sure about it )

Ng, Please try

gem 'paper_trail', 
  git: 'git@github.com:airblade/paper_trail.git', 
  branch: 'require_ar_and_as'

and let me know if that works for you. Thanks.

@jaredbeck Yes that solves the issue.

Fixed by #1043 expected release 9.0.0

Thanks Ng.
