potential mongoid bug

console.rb

--------------------------------------------------------------------------------------------
                        With one object saved, another in memory
--------------------------------------------------------------------------------------------
#setup
subject.copywriter_languages.create Factory.attributes_for(:copywriter_language, status: "deleted")
subject.copywriter_languages.build  Factory.attributes_for(:copywriter_language, status: "pending")

#Round 1
#checking default scope
subject.copywriter_languages.criteria
=> #<Mongoid::Criteria
  selector: {:status=>{"$ne"=>"deleted"}},
  options:  {},
  class:    CopywriterLanguage,
  embedded: true>

subject.copywriter_languages.count
=> 1

subject.copywriter_languages.first.status
=> "deleted"

# another weirdness: count wasn't supposed to be eq 1?
subject.copywriter_languages.map &:status
=> ["deleted", "pending"]

#this seems logic but why do I have an unsaved object here?
subject.copywriter_languages.unscoped.count
=> 2

#Round 2
#This finally works but retrieves the unsaved object
subject.copywriter_languages.where(:status.ne => :deleted)
=> #<Mongoid::Criteria
  selector: {:status=>{"$ne"=>"deleted"}},
  options:  {},
  class:    CopywriterLanguage,
  embedded: true>

#seems it finds the unsaved object
subject.copywriter_languages.where(:status.ne => :deleted).count
=> 1
subject.copywriter_languages.where(:status.ne => :deleted).first.status
=> "pending"

--------------------------------------------------------------------------------------------
                                When two objects in db
--------------------------------------------------------------------------------------------

#setup
subject.copywriter_languages.create Factory.attributes_for(:copywriter_language, status: "deleted")
subject.copywriter_languages.create  Factory.attributes_for(:copywriter_language, status: "pending")

#Round 1
#checking default scope
subject.copywriter_languages.criteria
=> #<Mongoid::Criteria
  selector: {:status=>{"$ne"=>"deleted"}},
  options:  {},
  class:    CopywriterLanguage,
  embedded: true>

#wring behavior
subject.copywriter_languages.count
=> 2

#proof
subject.copywriter_languages.map &:status
=> ["deleted", "pending"]

#Round 2
# works as expected. So same criteria as above but different result
subject.copywriter_languages.where(:status.ne => :deleted).criteria
=> #<Mongoid::Criteria
  selector: {:status=>{"$ne"=>"deleted"}},
  options:  {},
  class:    CopywriterLanguage,
  embedded: true>

subject.copywriter_languages.where(:status.ne => :deleted).count
=> 1

subject.copywriter_languages.where(:status.ne => :deleted).first.status
=> "pending"

models.rb

class LanguageSkill
  include Mongoid::Document
  
  default_scope where(:status.ne => "deleted")
  field :status, :type => String, :default => "pending"
end

class CopywriterLanguage < LanguageSkill 
  embedded_in   :profile,  :inverse_of => :copywriter_languages,   :validate => false   
end

@rubish: this was an issue, and the fix will be reeased in 2.4.9: https://github.com/mongoid/mongoid/issues/1917

Thanks for the information.
