Say you have a polymorphic setup like the following where all classes involved in the relationship use a custom id field of type String
class Picture include Mongoid::Document field :_id, type: String, pre_processed: true, overwrite: true, default: ->{ BSON::ObjectId.new.to_s } belongs_to :imageable, polymorphic: true end class Employee include Mongoid::Document field :_id, type: String, pre_processed: true, overwrite: true, default: ->{ BSON::ObjectId.new.to_s } has_many :pictures, as: :imageable end
If we create an employee and picture, then link them together so we have:
Employee.first => #<Employee _id: 539f42096c75633c62010000 > Picture.first => #<Picture _id: 539f428b6c75633c62020000, imageable_type: "Employee", imageable_id: "539f42096c75633c62010000"> Picture.first.imageable_id == Employee.first.id => true Picture.first.imageable_id.class => String
Then try to access the employee's pictures via the association, nothing is found - even though there is a picture associated with the employee
Employee.first.pictures
=> [] # this should've returned the first picture
Underneath the covers, the selector tries to find an imageable_id of type BSON::ObjectId, not String.
