Given a model with a Time field defined:
class MyModel
include Mongoid::Document
field :a, type: Time
end
When using any_of with multiple arguments, which Mongoid attempts to combine, and when using $exists as a symbol operator on the time field with a boolean value, Mongoid attempts to evolve the boolean value to a time which fails:
pp MyModel.any_of({:a.exists => true}, a: nil)

Did you mean? __evolve_object_id__
Note that `or` works when used instead of `any_of`:
(byebug) MyModel.or({:a.exists => true},{a:nil})
#<Mongoid::Criteria
selector: {"$or"=>[{"a"=>{"$exists"=>true}}, {"a"=>nil}]}
options: {}
class: MyModel
embedded: false>
Note that the various symbol operators have special value conversion logic defined in Criteria::Queryable::Selectable. For example, for $exists:
key :exists, :override, "$exists" do |value|
Mongoid::Boolean.evolve(value)
end
When Mongoid is combining conditions with operators, it needs to follow the various rules defined in that file for the various operators that are supported (others are $type and the geo ones).
