## Hstore type and predicates for Ent.

This package defines the [`Postgres hstore`](https://www.postgresql.org/docs/9/hstore.html) type

to be used with [`ent`](https://github.com/ent/ent) and a few predicates.

### Using the type:

```go

func (User) Fields() []ent.Field {

	return []ent.Field{

		field.Other("attributes", enthstore.Hstore{}).

			SchemaType(enthstore.Hstore{}.SchemaType()).

			Default(func() enthstore.Hstore {

				return enthstore.Hstore{}

			}),

	}

}

```

### Using the predicates:

```go

users, err := client.User.Query().Where(func(selector *sql.Selector) {

    selector.Where(enthstore.HasKey(user.FieldAttributes, "a"))

}).All(context.Background)

```

#### List of predicates:

- HasKey

- HasAllKeys

- ValueIsNull

- ValueEQ

- ValueNEQ

- ValueGT

- ValueGTE

- ValueLT

- ValueLTE

- ValueContains

- ValueHasPrefix

- ValueHasSuffix

### Using with [GQLGen](https://github.com/99designs/gqlgen):

Define a [custom scalar](https://gqlgen.com/reference/scalars/):

```graphql

scalar Hstore

```

And declare the type mapping on `gqlgen.yml`:

```yaml

models:

  Hstore:

    model: github.com/crossworth/enthstore.Hstore

```
