### 2. Create a sample OPA Policy

In another terminal, create a policy that allows root user all access and for all other users denies `PutObject`:

```sh
cat > example.rego <<EOF
package httpapi.authz

import input

default allow = false

				return
			}
		case "Separator":
			z.Separator, err = dc.ReadString()
			if err != nil {
				err = msgp.WrapError(err, "Separator")
				return
			}
		case "Create":
			z.Create, err = dc.ReadBool()
			if err != nil {
				err = msgp.WrapError(err, "Create")
				return
			}
		case "IncludeDirectories":
			z.IncludeDirectories, err = dc.ReadBool()
			if err != nil {
				err = msgp.WrapError(err, "IncludeDirectories")

        OneSizeTestContainerGenerator<ListMultimap<K, V>, Entry<K, V>> multimapGenerator) {
      super(multimapGenerator);
    }

    @Override
    public List<V> create(Object... elements) {
      return (List<V>) super.create(elements);
    }
  }

  private static final class MultimapAsMapGetGenerator<K, V>
      extends MultimapTestSuiteBuilder.MultimapAsMapGetGenerator<K, V, ListMultimap<K, V>>

        Callable<V> callable, long delay, TimeUnit unit) {
      return NeverScheduledFuture.create();
    }

    @Override
    public ListenableScheduledFuture<?> schedule(Runnable command, long delay, TimeUnit unit) {
      return NeverScheduledFuture.create();

## Создание приложения с единственной моделью { #create-the-app-with-a-single-model }

Сначала мы создадим самую простую первую версию приложения с одной моделью **SQLModel**.

Позже мы улучшим его, повысив безопасность и универсальность, добавив **несколько моделей**. 🤓

### Создание моделей { #create-models }

Импортируйте `SQLModel` и создайте модель базы данных:
