Question

我正在编写一个包含以下模型的日历应用程序：

class CalendarHour(models.Model):
    '''
    Each day there are many events, e.g. at 10 am, the framer orders
    material, etc.
    '''
    day_id = models.ForeignKey(CalendarDay)
    time = models.TimeField()
    work = models.TextField()

    def __unicode__(self):
        return 'work that took place at {work_time}'.format(work_time = self.time)

class CalendarDay(models.Model):
    '''
    Each project has so many daily logs.  But, each daily log belongs to     only one project (OneToMany relationship)
    '''
    company_id = models.ForeignKey(CompanyCalendar)
    day_date = models.DateField(auto_now_add = True) # Recording the date each log is entered in
    deadline = models.DateField() # The date for the daily log

现在，我想基于这些模型创建一个表单，其中包含有关当天的信息，但有24行条目实例，每行代表一个小时。所以，在forms.py中：＃forms.py 来自django.forms import ModelForm

class HourForm(ModelForm):
    class Meta:
         model = CalendarHour
        fields = ['entry_id', 'day_date', 'deadline']

class DayForm(ModelForm):
    class Meta:
        model = CalendarDay
        fields = ['company_id', 'day_date', 'deadline']

# In views.py:
...
class CalendarSubmit(View):
    template_name = 'calendar/submit.html'
    today_calendar = CalendarDay
    each_hour_calendar = CalendarHour

    def get(self, request):
        return render(request, self.template_name, {'form1': self.toady_calendar, 'form2':self.each_hour_calendar })

    def post(self, request):
        today = self.today_calendar(request.POST)
        each_hour = self.each_hour_calendar(request.POST)

        if today.is_valid():          
            today_calendar.save()

        if each_hour.is_valid():
            each_hour_calendar.save()

现在，我可以在模板中显示两种不同的表单，form_day和form_hour。我甚至可以重复使用form2字段24次，但是当它被发布时，第一个小时最终会在数据库中结束，其他小时将被忽略。我知道在管理员中，有一个添加多个实例的添加按钮，但我不知道如何在我的情况下实现这一点：如何在一个表单上显示两个相关模型，其中需要多次填充引用模型。 / p>

感谢任何帮助。
