## Multiple models { #multiple-models }

Here's a general idea of how the models could look like with their password fields and the places where they are used:

	elapsed := time.Since(begin)
	sql, rows := fc()
	fields := []slog.Attr{
		slog.String("duration", fmt.Sprintf("%.3fms", float64(elapsed.Nanoseconds())/1e6)),
		slog.String("sql", sql),
	}

	if rows != -1 {
		fields = append(fields, slog.Int64("rows", rows))
	}

	switch {
	case err != nil && (!l.IgnoreRecordNotFoundError || !errors.Is(err, ErrRecordNotFound)):
		fields = append(fields, slog.String("error", err.Error()))

For example, in one of the ways the OAuth2 specification can be used (called "password flow") it is required to send a `username` and `password` as form fields.

The <abbr title="specification">spec</abbr> requires the fields to be exactly named `username` and `password`, and to be sent as form fields, not JSON.

        BaseConfiguration testConfig = new BaseConfiguration(false);
        byte[] customMachineId = new byte[32];
        Arrays.fill(customMachineId, (byte) 0xFF);

        // Use reflection to set private field
        java.lang.reflect.Field machineIdField = BaseConfiguration.class.getDeclaredField("machineId");
        machineIdField.setAccessible(true);
        machineIdField.set(testConfig, customMachineId);

        byte[] header = buildHeader(NtStatus.NT_STATUS_BUFFER_OVERFLOW);

        // SrvPipePeekResponse expects at least 16 bytes (4 ints) output
        byte[] out = new byte[16];
        // leave all fields zero for simplicity

        byte[] body = buildIoctlResponseBody(Smb2IoctlRequest.FSCTL_PIPE_PEEK, new byte[16], 0, null, out.length, out, 0);
        byte[] packet = new byte[header.length + body.length];

  If the `DeclarativeValidation` feature gate is enabled, mismatches with existing validation are reported via metrics.
