Scoping not working under Rails 5

[cenotaph]

Hi,

The docs for scoping say to use referenced_in and references_many but these options appear to have been deprecated in favour of more ActiveRecord-style belongs_to and has_many (I think--??).

Under Mongoid 6.0.2 and mongoid-slug 5.3.1 (master branch), the scope option doesn't work (at least when set up with belongs_to and has_many -- using referenced_in and references_many, as specified in the docs, throws an exception, so what am I doing wrong?

Saving a record with a duplicate slugged attribute (but a different scope) throws the dreaded 'E11000 duplicate key error index' error. I've tried explicitly defining the _id association as well, as suggested by the docs.

If scoping is still possible, could the README.md please be updated to indicate how to do this?

Thanks!

Do you think you can write a spec for this?

[cenotaph]

No, don't really know how to do that. Could the documentation just be corrected? Is there something beyond changing reference_in to belongs_to and references_many to has_many?

[dblock]

Maybe. Make a pull request and we can talk about it. I didn't dig any deeper into the issue, but I can try.

Update

I had the same problem, updating to mongoid 6.0.3 solved!

That is working

A channel has several episodes:

Channel

class Channel
  include Mongoid::Document
  include Mongoid::Slug

  field :title, type: String

  slug :title

  validates :title, presence: true

  has_many :episodes
end

Episode

class Episode
  include Mongoid::Document
  include Mongoid::Timestamps
  include Mongoid::Slug
  
  field :title, type: String
  field :description, type: String
  field :url, type: String
  field :published_at, type: DateTime

  slug :title, scope: :channel

  validates :title, presence: true
  validates :url, presence: true
  validates :published_at, presence: true

  belongs_to :channel
  
end
