# Extra Models { #extra-models }

Continuing with the previous example, it will be common to have more than one related model.

This is especially the case for user models, because:

* The **input model** needs to be able to have a password.
* The **output model** should not have a password.
* The **database model** would probably need to have a hashed password.

This document provides a general guidelines for using and working on the elasticsearch build logic.

## Build logic organisation

The Elasticsearch project contains 3 build-related projects that are included into the Elasticsearch build as a [composite build](https://docs.gradle.org/current/userguide/composite_builds.html).

### `build-conventions`

    //                                                                           Attribute
    //                                                                           =========
    /** The time manager for handling time-related operations. */
    @Resource
    private TimeManager timeManager;

    /** The async manager for handling asynchronous operations. */
    @Resource
    private AsyncManager asyncManager;

        assertEquals(SmbConstants.ATTR_READONLY | SmbConstants.ATTR_DIRECTORY, info.getAttributes());
    }

    @Test
    @DisplayName("Test time-related methods always return 0")
    void testTimeRelatedMethods() {
        // Default instance
        assertEquals(0L, shareInfo.createTime());
        assertEquals(0L, shareInfo.lastModified());

}

// Simple tests of bucket lifecycle: PUT, GET, DELETE.
// Tests are related and the order is important.
func testBucketLifecycleHandlers(obj ObjectLayer, instanceType, bucketName string, apiRouter http.Handler,
	creds auth.Credentials, t *testing.T,
) {

The generated code still has some **duplicated information**.

We already know that this method is related to the **items** because that word is in the `ItemsService` (taken from the tag), but we still have the tag name prefixed in the method name too. 😕

	// Test for Anonymous/unsigned http request.
	// Bucket policy related functions doesn't support anonymous requests, setting policies shouldn't make a difference.
	bucketPolicyStr := fmt.Sprintf(bucketPolicyTemplate, bucketName, bucketName)
	// create unsigned HTTP request for PutBucketPolicyHandler.

func loadAPIRequestsHTTPMetrics(ctx context.Context, m MetricValues, _ *metricsCache) error {
	// Collect node level S3 HTTP metrics.
	httpStats := globalHTTPStats.toServerHTTPStats(false)

	// Currently we only collect S3 API related stats, so we set the "type"
	// label to "s3".

	m.Set(apiRejectedAuthTotal, float64(httpStats.TotalS3RejectedAuth), "type", "s3")
	m.Set(apiRejectedTimestampTotal, float64(httpStats.TotalS3RejectedTime), "type", "s3")

	}
	objInfo.Checksum = fi.Checksum
	objInfo.decryptPartsChecksums(nil)
	objInfo.Inlined = fi.InlineData()
	// Success.
	return objInfo
}

// TransitionInfoEquals returns true if transition related information are equal, false otherwise.
func (fi FileInfo) TransitionInfoEquals(ofi FileInfo) bool {
	switch {
	case fi.TransitionStatus != ofi.TransitionStatus,
		fi.TransitionTier != ofi.TransitionTier,
