<<QuerySet [{'id': 217186, 'day': '1'}, {'id': 217187, 'day': '1'}, {'id': 217188, 'day': '1'}, {'id': 217189, 'day': '1'}, {'id': 217190, 'day': '1'}, {'id': 217191, 'day': '1'}, {'id': 217192, 'day': '1'}, {'id': 217193, 'day': '1'}, {'id': 217194, 'day': '1'}, {'id': 217195, 'day': '2'}, {'id': 217196, 'day': '2'}, {'id': 217197, 'day': '2'}, {'id': 217198, 'day': '2'}, {'id': 217199, 'day': '2'}, {'id': 217200, 'day': '2'}, {'id': 217201, 'day': '2'}, {'id': 217202, 'day': '2'}, {'id': 217203, 'day': '2'}, {'id': 217204, 'day': '3'}, {'id': 217205, 'day': '3'}, '...(remaining elements truncated)...']>
