Model authors

The system plugin author automatically adds for each collection the attributes:

• created_by {user} - set on model's creation
• updated_by {user} - set on model's modification

It is not enabled by default.

The following plugin options must be specified:

• currentuser {function}: retrieves the current request's user. Cannot return null if the user is anonymous.
• collection {string}: user's collection name.

plugins:
  - plugin: author
    opts:
      currentuser:
        $ref: get_user.js
      collection: users
