Rails 5. Draft version and publish version of model

Question

Which is the best way to have a draft version of a model? I have a Course model with his description and lesson models.

class Course < ApplicationRecord
 has_many :lessons
 has_one :description
...
end

class Description < ApplicationRecord
 belongs_to :course
...
end

class Lesson < ApplicationRecord
 belongs_to :course
...
end

The description and lesson model have a state machine with a "published" status, that when they have it, their information will be published. I need the draft version to modify their information without change the published information. How can I do this?

PD: I have tried to use the draftsman gem, but doesn't work with Rails 5.

You could try draftpunk or use their approach to implement your custom solution.

Idea is to create store a draft version in the same database table. Just with an id referer. In your application you have to take care:

Display to end users -> make a scope where you just return non-drafts (so the foreign id is nil)
When call edit -> return the draft version of model, if nil -> create one. Let the user ony edit draft versions.
Setup a publish action and a button in your frontend: Call a 'publish' function where you take care of handling the data publish process

I am interested how you end up
