如何显示Django中所有用户的每日日程安排？

Question

我正在使用Django为健身房教练做一个网站。 我想是所有培训师这样

但每天的日程安排一个模板，我的网页是

的问题是每个教练的TR重复多达数量“TD”训练师的时间表。我知道{% for sc in schedules %}是问题所在。但是，因为时间表是查询集合，所以我应该使用for和while来使用for，我应该检查将时间表插入到右侧tr，td位置的正确时间。我如何让成功的表格显示所有用户（培训师）的每日时间表？任何人都会对我非常有帮助。

Schedule.model

class Schedule(models.Model): 
    Trainer = models.ForeignKey(settings.AUTH_USER_MODEL,blank=True,null=True, related_name='schedule', on_delete=models.SET_NULL) 
    title = models.CharField(max_length=12,blank=True,) 

    start = models.DateTimeField(null=True, blank=True) 

我views.py

def staff_daily_schedule_search(request): 

all_schedules = Schedule.objects.all() 
Fitness_list = User.objects.filter(groups__name='Fitness') # Fitness Trainers 

search_date1 = request.GET.get('search_date','') 
search_date= datetime.datetime.strptime(search_date1, '%Y-%m-%d') #%T = %H:%M:%S '%Y-%m-%d' 

schedules= Schedule.objects.none() 
for f in Fitness_list: 
    sc = f.schedule.filter(start__year=search_date.year).filter(start__month = search_date.month).filter(start__day = search_date.day) 
    print(sc) 
    schedules |= sc 

context = { 
    'search_date' : search_date1 if search_date1 else datetime.date.today(), 
    'Fitness_list':Fitness_list, 
    'schedules' : schedules,

如果你把逻辑视图，而不是的模板，很容易就像你想要的那样设置桌子。

[编辑，以使用OrderedDict维护培训人员的顺序。]

views.py

def staff_daily_schedule_search(request): 

    Fitness_list = User.objects.filter(groups__name='Fitness') # Fitness Trainers 

    search_date1 = request.GET.get('search_date','') 
    search_date= datetime.datetime.strptime(search_date1, '%Y-%m-%d') #%T = %H:%M:%S '%Y-%m-%d' 

    trainer_dict = OrderedDict() 
    # Initialize each row of the table with the trainer's name and a blank schedule 
    for f in Fitness_list: 
     trainer_dict[str(f.id)] = {'name': f.get_full_name(), 'hour_21': '', 
      'hour_22': '', 'hour_23': '', 'hour_0': '', 'hour_1': ''} 

    schedules = Schedule.objects.filter(start__year=search_date.year).filter(start__month = 
     search_date.month).filter(start__day = search_date.day) 
    # Insert each schedule item into the appropriate table row and cell 
    for sc in schedules: 
     trainer_dict[str(sc.Trainer.id)]['hour_' + str(sc.start.hour)] = sc.title 

    context = { 
     'search_date' : search_date1 if search_date1 else datetime.date.today(),
