Why new record type is pluralized as per default?

I think the reason for it is that it’s a pretty standard convention to pluralize API endpoints for a resource like that, and therefore pluralizing is a sensible default. For example it would be very common to have a ‘user’ model and have the API endpoints be /users and /users/:id.

To customize it, put the following in your adapter:

  // don't pluralize, just return type as-is
  pathForType: function(type) {
    return type;
  },

You can customize it per-model if you use a per-model adapter, or application-wide with the application adapter.
