For the examples below with DataStore let's add a new model to the [sample schema](/lib/datastore/getting-started#sample-schema):

```graphql
enum PostStatus {
  ACTIVE
  INACTIVE
}

type Post @model @auth(rules: [{allow: public}]) {
  id: ID!
  title: String!
  rating: Int!
  status: PostStatus!
  # new field with @hasMany
  comments: [Comment] @hasMany
}

# new model
type Comment @model {
  id: ID!
  content: String
  post: Post @belongsTo
}
```
