Error with queryset.values

[brykov93]

Hi. I needed to display data after applying queryset.values. As a result, instead of data, ??? in all columns. Model:

class StudyUploadLog(models.Model): study_instance_uid = models.CharField(max_length=150, verbose_name='Study Instance UID') patient = models.CharField(max_length=150, verbose_name='Patient') instance_uid = models.CharField(max_length=150, verbose_name='Instance UID') upload_date = models.DateTimeField(verbose_name='Upload time') completed = models.BooleanField(verbose_name='Completed', default=False)

View:

class UploadingStudies(AjaxDatatableView): model = StudyUploadLog title = 'Лог получения исследований' #initial_order = [["upload_date", "desc"], ] length_menu = [[50, 100, -1], [50, 100, 'Все']] search_values_separator = '+' disable_queryset_optimization_only = True column_defs = [ {'name': 'id', 'visible': False, 'searchable': False, }, {'name': 'patient', 'title': 'Пациент', 'searchable': False, 'visible': True}, {'name': 'study_instance_uid', 'title': 'Идентификатор исследования', 'searchable': False, 'visible': True}, # {'name': 'progress', 'title': 'Прогресс', 'searchable': False, 'visible': True}, {'name': 'images_count', 'title': 'Количество файлов', 'searchable': False, 'visible': True}, {'name': 'start_date', 'title': 'Время начала приема', 'searchable': False, 'visible': True}, {'name': 'end_date', 'title': 'Время окончания приема', 'searchable': False, 'visible': True}, {'name': 'completed', 'title': 'Прием окончен', 'searchable': False, 'visible': True, 'boolean': True,}, ] def get_initial_queryset(self, request=None): queryset = super().get_initial_queryset(request=request) queryset = (queryset.values('patient', 'study_instance_uid', 'completed') .annotate(images_count=Count('instance_uid'), id=Max('id'), start_date=Min('upload_date'), end_date=Max('upload_date'))) return queryset
