Ember how to use multiple adapters?

I have an ember app that hooks into a rails-api. I am using devise for authentication and have an application.js adapter set up for the authorization. Now I want to connect to my rails DB model and display some data. I need to add the ActiveModelAdapter to connect. How do I add in a second ActiveModelAdapter so I can use it? I'm just getting started with Ember so I wasn't sure.

    import DS from 'ember-data';
    import DataAdapterMixin from 'ember-simple-auth/mixins/data-adapter-mixin';
    import ActiveModelAdapter from 'active-model-adapter';

    export default DS.JSONAPIAdapter.extend(DataAdapterMixin, {
      authorizer: 'authorizer:devise'
    });
