This is strange behaviour and I wanted to see if this is right. When a pass a `model` (and just the `model`) to a the `{{#link-to}}` helper, I get the following error: `Assertion Failed: You cannot pass 'undefined' as id to the store's find method`

However, when I use `model.id`, the error doesn’t occur. Based on the [documentation](https://guides.emberjs.com/v2.15.0/templates/links/), I thought the `{{#link-to}}` helper was meant to use the `id` property by default?

That is how I understand it. I presume the find() call is in a model hook? It won’t even fire the model hook if you pass an object. What does your router look like? And I’d also suggest triple-checking the spelling of the object variable name you are passing in the link-to.
