## Nested Models { #nested-models }

Each attribute of a Pydantic model has a type.

But that type can itself be another Pydantic model.

So, you can declare deeply nested JSON "objects" with specific attribute names, types and validations.

All that, arbitrarily nested.

### Define a submodel { #define-a-submodel }

For example, we can define an `Image` model:

import org.apache.maven.api.annotations.Nonnull;

/**
 * Event sent by maven during various phases of the build process.
 * Such events can be listened to using {@link Listener}s objects
 * registered in the {@link Session}.
 *
 * @since 4.0.0
 */
@Experimental
public interface Event {

    /**
     * Gets the type of the event.
     *

    /** The object name is invalid */
    int NT_STATUS_OBJECT_NAME_INVALID = 0xC0000033;
    /** The object was not found */
    int NT_STATUS_OBJECT_NAME_NOT_FOUND = 0xC0000034;
    /** The object name already exists */
    int NT_STATUS_OBJECT_NAME_COLLISION = 0xC0000035;
    /** The port is disconnected */
    int NT_STATUS_PORT_DISCONNECTED = 0xC0000037;
    /** The object path is invalid */

    }

    /**
     * Wraps an object instance into a pooled object.
     * @param obj The object to wrap
     * @return A PooledObject wrapping the given object
     */
    @Override
    public PooledObject<T> wrap(final T obj) {
        return new DefaultPooledObject<>(obj);
    }

    /**
     * Destroys a pooled object and notifies the destroy listener if set.

		t.Errorf("Open err:%v", err)
	}

	type Object1 struct{}
	type Object2 struct {
		Field1 string
	}
	type Object3 struct {
		Field2 string
	}
	db.Migrator().DropTable("objects")

	err = db.Table("objects").AutoMigrate(&Object1{})
	if err != nil {
		t.Errorf("AutoMigrate err:%v", err)
	}

	err = db.Table("objects").AutoMigrate(&Object2{})
	if err != nil {

    }

    @Override
    public boolean equals(final Object obj) {
        if (this == obj) {
            return true;
        }
        if (obj == null || getClass() != obj.getClass()) {
            return false;
        }
        final DefaultQueryBuilder other = (DefaultQueryBuilder) obj;
        return Objects.equals(queryBuilder, other.queryBuilder);
    }

    @Override

        this.ptype = 0;
        this.flags = DCERPC_FIRST_FRAG | DCERPC_LAST_FRAG;
    }

    /**
     * Returns the DFS root entries retrieved from the enumeration.
     *
     * @return an array of FileEntry objects representing the DFS roots
     */
    public FileEntry[] getEntries() {
        final netdfs.DfsEnumArray200 a200 = (netdfs.DfsEnumArray200) this.info.e;
        final SmbShareInfo[] entries = new SmbShareInfo[a200.count];
