Mongoid / Moped Date Type Insertion Failure

The problem deals with mongoid / moped DATE type insertion. My code is below

s=Moped::Session::new(["127.0.0.1"])
s.use "test"
s["a"].insert mydate: Date.strptime("10/02/2014","%m/%d/%Y")

raises an error

# => undefined method `__bson_dump__' for Thu, 02 Oct 2014:Date

Why does Date type fails to insert into mongoDB via moped? I am pretty sure that mongoDB does support Date type.

Thank you for the help.

MongoDB supports BSON type UTC datetime, in Moped this is mapped to Ruby Time, not Date. However, there is a very easy solution for your code, as Mongoid provides the Date#mongoize convenience function. Hope that this is what you want and that it helps.

date_mongoize.rb

require 'moped'
require 'mongoid'

s=Moped::Session::new(["127.0.0.1"])
s.use "test"
s["a"].find.remove_all
s["a"].insert mydate: Date.strptime("10/02/2014","%m/%d/%Y").mongoize
p s["a"].find.to_a

$ ruby date_mongoize.rb

[{"_id"=>"5272a943fa23bace4f7650e3", "mydate"=>2014-10-02 00:00:00 UTC}]
