      It seems that declaring dependents in one document type also adds these dependents to any sibling class. Attempting to delete or destroy an instance of the sibling therefore fails.

      Example:

      class ReportCard
  include Mongoid::Document
end

class User
  include Mongoid::Document
end

class Student < User
  has_many :report_cards, class_name: 'ReportCard', dependent: :destroy
end

class CollegeUser < User
end

def main
  c = CollegeUser.create
  puts c.dependents
  c.destroy
end

      The output of the above is as follows:

      #<Mongoid::Association::Referenced::HasMany:0x00007fdd5ad031a0>
NoMethodError: undefined method `report_cards' for #<CollegeUser2:0x00007fdd50872cd0>
from /Users/luke/.rbenv/versions/2.3.7/lib/ruby/gems/2.3.0/gems/mongoid-7.0.1/lib/mongoid/association/depending.rb:86:in `_dependent_destroy!'
