    copied!<p>My models.py:</p> <pre><code>class Company(models.Model): company_name = models.CharField(max_length=255) class TimePeriod(models.Model): period = models.CharField(max_length=4) class Unit(models.Model): unit_name = models.CharField(max_length=50) unit_type = models.CharField(max_length=50) class DataElement(models.Model): data_element_name = models.CharField(max_length=50) class Source(models.Model): source_name = models.CharField(max_length=50) class CompanyData(models.Model): company = models.ForeignKey(Company) time_period = models.ForeignKey(TimePeriod) data_element = models.ForeignKey(DataElement) unit = models.ForeignKey(Unit) source = models.ForeignKey(Source) value = models.DecimalField(max_digits=15, decimal_places=2) </code></pre> <p>I'd like to have form similar to:</p> <p>--company--, --time period--</p> <ul> <li>data element1: --value--, --unit--, --source--</li> <li>data element2: --value--, --unit--, --source--</li> <li>...</li> <li>data elementN: --value--, --unit--, --source--</li> </ul> <p>My forms.py now:</p> <pre><code>class CompanyTimeForm(ModelForm): class Meta: model = CompanyData fields = ('company', 'time_period') class CompanyDataForm(ModelForm): # data_element = forms.IntegerField(widget=forms.HiddenInput()) # def __init__(self, extra): # ... init data_element ... class Meta: model = CompanyData fields = ('value', 'unit', 'source') </code></pre> <p>and usage:</p> <pre><code>top_form = CompanyChainTimeForm(request.POST or None) CompanyDataFormSet = formset_factory(CompanyDataForm, extra=X) formset = CompanyDataFormSet() </code></pre> <p>Is it possible to initialize empty formset, then fetch DataElement.objects.all() and make something similar to formset.add(CompanyDataForm(...DataElement.pk...))</p> <p>Or what would be the best option for my case?</p>
