In MongoDB integration tests ( test/models/mongoid\_models.rb[https://github.com/karmi/tire/blob/master/test/models/mongoid\_models.rb](https://github.com/karmi/tire/blob/master/test/models/mongoid_models.rb))are shown some  
referenced 1-n [http://mongoid.org/en/mongoid/docs/relations.html#has\_many](http://mongoid.org/en/mongoid/docs/relations.html#has_many)mongoid relations.

Is that applicable to embedded 1-n[http://mongoid.org/en/mongoid/docs/relations.html#embeds\_many](http://mongoid.org/en/mongoid/docs/relations.html#embeds_many)relations too out of the box, or some more tricks are needed ?

Is that possible to extend test/models/mongoid\_models.rb[https://github.com/karmi/tire/blob/master/test/models/mongoid\_models.rb](https://github.com/karmi/tire/blob/master/test/models/mongoid_models.rb)with embeds\_many  
/ embedded\_in example models ?

I tried doing the following:

class User

include Mongoid::Document

include Tire::Model::Search

include Tire::Model::Callbacks

tire do

```
mapping do

  indexes :nickname

  indexes :watchlists do

    indexes :description

    indexes :html_url

    indexes :tags

  end

end

```

end

def to\_indexed\_json

```
{

  :nickname => nickname,

  :watchlists => watchlists.map { |c| { :_type => 'mongoid_watchlist',

                                        :_id => c.id,

                                        :description => c.description,

                                        :html_url => c.html_url,

                                        :tags => c.tags } }

}.to_json

```

end

field :nickname

embeds\_many :watchlists

end

class Watchlist

include Mongoid::Document

field :description

field :html\_url

field :tags

embedded\_in :user

end

but then, running tire:import, it seems never ending :

RAILS\_ENV=production rake environment tire:import CLASS=User FORCE=true
