如何显示Django中所有用户的日程安排？

Question

I'm using Django to make a website for gym trainers. what I want is a template for the daily schedules of all trainers like this

But, my page is

The problem is the 'td' of per trainer's tr repeats as many as the number of schedules the trainer has. I know the {% for sc in schedules %} is the problem. But, because schedules are the query set, I should use the for and while using for, I should check the right time to insert the schedule to the right tr, td position. How can I make the successful table to show the daily schedules of all users(trainers)?? Anybody will be very helpful to me.

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)

my 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,
}
return render(request, 'management/staff_daily_schedule.html', context)

The problem

Answer 1

If you put the logic in your view instead of the template, it's easy to set up the table exactly like you want it.

[Edited to use an OrderedDict to preserve the order of trainers.]

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(), 
        'trainer_dict': trainer_dict
    }
    return render(request, 'management/staff_daily_schedule.html', context)
