I’ve created a Transaction supermodel using the DoneJS generator. If I’ve already retrieved a list of Transaction instances. **How can I look up a Transaction instance from the store by id?**

I see in [the code for can/model](https://github.com/canjs/can-connect/blob/master/src/can/model/model.js#L219) that there is a store attribute that’s based off the `constructor-store` behavior. Is this not available for SuperMap?

Also, is can-connect hosted anywhere that I could use it in a jsbin?

Docs page has a jsbin [http://connect.canjs.com/doc/index.html](http://connect.canjs.com/doc/index.html)

Instances are on [http://connect.canjs.com/doc/can.connect|constructor-store.instanceStore.html](http://connect.canjs.com/doc/can.connect%7Cconstructor-store.instanceStore.html)

Thanks. I found my problem. I was trying to pass the id directly instead of providing an object with the id:

```auto
Transaction.get(id)

```

instead of

```auto
Transaction.get({_id:id})

```

I wonder if we should support both, I would think `get` is oftened used to retrieve an item by id.

@matthewp I think that’s doable if `idProp` is set.

I have idProp set and it wasn’t working. I’ll look into to to see if it’s a bug.

it’s not designed to work that way. I was only trying to say that it could work that way if `idProp` was set

I see. Thanks for the clarification.
