Rails 5.1 migration incompatibility

[travisp]

In the Rails 5.1 rc1, the migrations created by PaperTrail 7.0.0 do not work and cause this error:

Directly inheriting from ActiveRecord::Migration is not supported. Please specify the Rails release the migration was written for

The migration has to be updated from

class CreateVersions < ActiveRecord::Migration

to something like:

 class CreateVersions < ActiveRecord::Migration[4.2]

It appears that this is still the case in the master branch of PaperTrail

Thanks Travis, that makes sense. How can we change our "migration template" (paper_trail/templates/create_versions.rb) to output the user's rails version?

[jaredbeck]

It looks like devise uses erb to accomplish this.

https://github.com/plataformatec/devise/blob/master/lib/generators/active_record/templates/migration.rb

I don't know if that's an option for us, but it's one thing we could look into.

Closed by #950. Will release in 7.0.1. Thanks Travis.

i was actually running 7.0.2. At least this is what my gemfile lock says:

  paper_trail (7.0.2)
    activerecord (>= 4.0, < 5.2)
    request_store (~> 1.1)
