django class-based views with inline model-form or formset

Question

I have the following models:

class Bill(models.Model):
    date = models.DateTimeField(_(\"Date of bill\"),null=True,blank=True)

class Item(models.Model):
          


        

Answer 1

I made some modification to original solution to let formset.is_valid() to work:

    if self.request.POST:
        context['fs'] = MyInlineFS(self.request.POST, instance=self.object)
    else:
        context['fs'] = MyInlineFS(instance=self.object)
