I have a database manager singleton that I create with the following:

```
App.Mongo = Ember.Object.extend({...})

App.register("mongo:main", App.Mongo);
App.inject("route", "mongo", "mongo:main");
App.inject("controller", "mongo", "mongo:main");

```

Now inside that I want to use another singleton:

```
App.Factory = Ember.Object.extend({...})

App.register("factory:main", App.Factory);
App.inject("route", "factory", "factory:main");
App.inject("controller", "factory", "factory:main");
App.inject("object:mongo", "factory", "factory:main");

```

Is there a supported way to accomplish this yet?

I’d like to know the answer to this as well. I’ve got a factory I’d like to inject my socket and store singletons into. I thought it would be something as simple as:

```auto

Ember.Application.initializer({
    name: "factory",
    after: "socket",

    initialize: function (container, application) {
        container.register('factory:main', Ember.Factory);
         application.inject('factory:main', 'store', 'store:main');
         application.inject('factory:main', 'socket', 'socket:main');
    }
});

```

Where `Ember.Factory = Ember.Object.extend({})`;

However, calling `Ember.Factory.create()` does not result in an object with `store` and `socket` properties.

My factory happens to be something that’s meant to be extended, much like `DS.Model`. My App has `App.FooFactory = Ember.Factory.extend();`. Instances of App.FooFactory also fail to have session and store properties.

I’ve tried several variations on what I register, what I inject upon, and when / how I create the FooFactory instance, but all fail to have `store` or `socket` injected.
