Django 外鍵模糊查詢方法

Django里面外鍵查詢不用點查詢，而是使用雙下划線”__”，如下：

如：查詢外鍵dormitory_id的id包含“D2”的學生

Student.objects.filter(dormitory_id__id__contains = “D2”)

如：查詢外鍵dormitory_id的id包含“D2”的學生（忽略大小寫）

Student.objects.filter(dormitory_id__id__icontains = “D2”)

如：查詢外鍵dormitory_id的id開頭包含“D2”的學生

Student.objects.filter(dormitory_id__id__startswith = “D2”)

如：查詢外鍵dormitory_id的id結尾包含“D2”的學生

Student.objects.filter(dormitory_id__id__endswith = “D2”)
