How to display the filled formset of all data from the table at once?

Question

Django

There is a table with 10 entries, how to display the completed formset of all this data with the possibility of editing it? More precisely, I do not need to display all the data, but on a certain basis, but not the essence.

I think the documentation https://docs.djangoproject.com/en/1.8/ref/forms/models/
about filtering data in forsets will help you understand the formsets, examples - stackoverflow.com/questions/9711313/django-how-to- ... , stackoverflow.com/questions/2581049/filter-queryse...
well, if you are completely depressed, then an example:
form:

class DatesOperationForm(forms.ModelForm):
    class Meta:
        model = OperationDate

DateFormSet = inlineformset_factory(Operation, OperationDate, extra=1, can_delete=False, form=DatesOperationForm)

view:

class OperationDetail(UpdateView):
    form_class = OperationForm
    

    def get_context_data(self, **kwargs):
        context = super(OperationDetail, self).get_context_data(**kwargs)
        context['form_dates'] = DateFormSet(instance=self.object)
        return context

models:

class Operation(models.Model):
    name = models.CharField(u"Название", max_length=255)
    sum = models.DecimalField(u"Сумма", max_digits=10, decimal_places=2)
    category = models.ForeignKey(CategoryOperation, verbose_name=u"Категория", null=True, blank=True,
                                 related_name='operations')
   ...
class OperationDate(models.Model):
    operation = models.ForeignKey(Operation, verbose_name=u"Опреация")
    ....

In fact, you pass instance Operation to the formset, everything else will be done by Dzhang itself. Well, if necessary, conjure with queryset.
