Getting Started example not working

[Johnny Tee]

Hi LoopBackers,

I am attempted the getting started tutorial, but I seem to keep getting an error when trying to POST with the API Explorer GUI. 

I have tried creating more models, but still no luck, any ideas?

Here is what I get in my shell :

Browse your REST API at http://localhost:3000/explorer

Unhandled error for request POST /api/CoffeeShops: ValidationError: The `CoffeeShop` instance is not valid. Details: `id` can't be set (value: 0).

It looks like this model will insert an "id" for you; what happens if you try to POST without an id property?

[Mark Johnson]

Loopback3 won't let you specify the ID for a new instance unless you set forceId to false in that model's configuration.

[Raymond Feng]

Do you have a fresh checkout from https://github.com/strongloop/loopback-getting-started? If so, the forceId is already set to false by https://github.com/strongloop/loopback-getting-started/commit/cf067254b4d64fb25b9fdd0a1707a85038fad00f. I confirm it works for me.

Thanks,

Raymond
