A quick hint, on how to have an 'id' attribute in Mongoid document JSON:
When you serialize Mongoid objects to JSON, you won't get ID attribute, similar to ActiveRecord. Instead you'll have "_id" attribute containing "$oid" value:
{
"_id": {"$oid":"52d3fdfd53656e5180020000"},
"changed_at":"2014-02-15",
"created_at":"2014-01-13T15:53:49.444+01:00",
"updated_at":"2014-01-13T15:53:49.444+01:00"
}
If you would prefer something like this:
{
"id": "52d3fdfd53656e5180020000",
"_id": {"$oid":"52d3fdfd53656e5180020000"},
"changed_at":"2014-02-15",
"created_at":"2014-01-13T15:53:49.444+01:00",
"updated_at":"2014-01-13T15:53:49.444+01:00"
}
Just put this into your initializers (for example in config/initializers/mongoid.rb):
module Mongoid
module Document
def as_json(options={})
attrs = super(options)
attrs["id"] = attrs["_id"].to_s
attrs
end
end
end
