When following the More Data section of the tour, the schema definition from [tutorial/1.txt at b9f10c9520097894a16431b8aa6df5d8dcf3d238 · dgraph-io/tutorial · GitHub](https://github.com/dgraph-io/tutorial/blob/b9f10c9520097894a16431b8aa6df5d8dcf3d238/content/moredata/1.txt) raises an error:

```auto
Could not alter schema: Schema does not contain a matching predicate for field actor.film in type Person

```

Suggest adding the following (or similar) to the schema:

```auto
actor.film: [uid] @reverse .

```

For reference, the schema at [Dgraph Ratel Dashboard](https://play.dgraph.io/?dev) has

```auto
<actor.film>: [uid] @count .

```
