Methods defined in serializer are not used

Expected behavior vs actual behavior

Possibly related to #1658.

I expect the methods defined in the serializer to be used for the attributes.

What is happening is the attribute is invoked on the object, resulting in an error if the method does not exist.

Steps to reproduce

(e.g., detailed walkthrough, runnable script, example application)

• clone https://github.com/NullVoxPopuli/aeonvera
• clone https://github.com/NullVoxPopuli/aeonvera-ui
• add swing.vhost to your hosts file
• boot up both apps.
• visit swing.vhost:4200 (the ember-app)
• create an account
• open the network log
• login
• notice the call to current user fails, and gives this error message:

Additonal helpful information

(e.g., Gemfile.lock, configurations, PR containing a failing test, git bisect results)

https://github.com/NullVoxPopuli/aeonvera/blob/master/Gemfile.lock

I tried working on a failing test with the AMS code, but something funky is happening, I'll continue to investigate.

which is weird, because no code changes have occurred after that commit -- just documentation changes.
