[Rails] Setting model association `source_type` to polymorphic object

I am trying to setup a way for my `User` and `Project` model to both be followed through the same `Relationship` model. I also want to be able to get all items the user has followed with this association: `has_many :following, through: :active_relationships, source: :followable, source_type:

[Rails] I have a question about `ActiveRecord.locking_column`.

Suppose the User model defines a column like this and does not have lock_version ``` class DeviseCreateUsers < ActiveRecord::Migration[5.1] def change create_table :users do |t| t.string :name # do not have a lock_version and other optimistic locks end end end ```
