title: Django how to enter multiple records on one form
body: <p>I am writing a calendar app with the following models:</p>
  
  <pre><code>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
  </code></pre>
  
  <p>Now, I want to create a form based on these models that has the information about the day, but 24 rows of entry instances, each representing one hour. So, in forms.py:
      #forms.py
      from django.forms import ModelForm</p>
  
  <pre><code>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()
  </code></pre>
  
  <p>Now, I can show two different forms in the template, form_day and form_hour.  I can even repeat the form2 fields 24 times, but when it is posted, the first hour ends up in the database and the others are ignored.  I know in the admin, there is an add buttom that adds multiple instances, but I do not know how to achieve this in my case: how to display two relating models on one form where the referring model needs to be populated multiple times.</p>
  
  <p>Any help is appreciated.</p>
