Create a `hasmany` which has a `hasmany` with loopback

Question

Hi is it possible to create a chained hasmany relationship like this:

Customer has Sensors and Sensors has Meterings

Customer -> Sensors -> Metering

So that i can access Meterings over the Customer Model.

For Example: http://localhost:3000/api/Customers/1/Sensors/2/Meterings

Is this possible in anyway with loopback?

You can chain model relations with include filter. http://docs.strongloop.com/display/public/LB/Include+filter — A.Z., Jun 11 '15 at 18:41

You can create hasAndBelongsToMany and hasManyThrough relations to achieve this. It's likely that your API call would end up looking something like:

/Customers/1?filter={"include":["meterings"],"where":{"sensorId":2}}
