NoMethodError (undefined method `undiscarded?' ...

[Porter Bayne]

Describe the bug
When using the readme's proposed code for handling associations, I get this error when calling .kept on a record:

undefined method `undiscarded?'`

Happens on both Discard 1.0 or 1.1.

(I am 99% sure this is some oversight on my part, but can't find it.)

To Reproduce

• I have an Encounter model and an Appointment model.
• Both have include Discard::Model as the first line in the model class code
• Encounter belongs_to Appointment

class Encounter < ApplicationRecord
  include Discard::Model
  scope :kept, -> { undiscarded.joins(:appointment).merge(Appointment.kept) }

  def kept?
    undiscarded? && appointment.kept?
  end

  belongs_to :appointment, optional: true
  ...
end

Then in the Rails (5.2.3) console:
Encounter.first.kept?

Produces

NoMethodError (undefined method `undiscarded?' for #<Encounter:0x00007fc44fa9cb88>)
Did you mean?  undiscard
               discarded?
               undiscard!

Hey! Any chance you could provide the full stack trace for this error (at least enough of it that I can see the call to .kept that's causing this? It would give me a much better idea of the sequence of events that cause this.

[Jared Norman]

Oh, just realized what it was. The undiscarded? method is on master but hasn't been released yet, so the rest of your code should work, but that predicate method doesn't exist. I'll have to cut a v1.2 here soon.

Thanks a ton for taking time to respond and explain!

[Jared Norman]

v1.2 is out now!
