I have a simple problem and documentation is not helping me resolve it.

I have created a Grails v3.3.3 demo project - and created a simple domain class called JsonApiBook, with 'name' attribute like this

```
package ttrestapi

import grails.rest.*

@Resource (uri='/jsonApiBook', formats=['json','xml'])
class JsonApiBook {

    static constraints = {
    }

    String name
}

```

and marked up the URI as the documentation says the JSON API rendering only works with domain classes (and not a controller class).

In my bootstrap I have saved a instance of book to the tables - and can view that generally.

In my views directory I have a created jsonApiBook folder and created two gson files.

A '\_jsonApIBook' template like this

```
import ttrestapi.JsonApiBook

model {
    JsonApiBook book
}
json jsonapi.render(book)

```

which invokes the jsonapi helper object to render the instance.

I have in the same directory created an index.json like this:

```
import ttrestapi.Book

model {
    List<Book> bookList
}

// We can use template namespace
// method with a Collection.
json tmpl.book(bookList) 

```

When I run the app and use postman or browser to render then I get a result but its Json api compliant (I think it's ignored the template).

So localhost:8080/jsonApiBook just returns (looks default layout):

```
[
    {
        "id": 1,
        "name": "json api book3"
    }
]

```

and localhost:8080/jsonApiBook/1 just returns 'null' which can't be right.

How should I be setting up the json views for rendering JSON API compliant output? As this doesn't appear to work correctly.
