Answer 1

 from django.utils.functional import curry class DetailsInline(admin.TabularInline): model = Details formset = DetailsFormset extra = 3 def get_formset(self, request, obj=None, **kwargs): initial = [] if request.method == "GET": initial.append({ 'label': 'first name', }) formset = super(DetailsInline, self).get_formset(request, obj, **kwargs) formset.__init__ = curry(formset.__init__, initial=initial) return formset 

From here: Pre-populate the embedded FormSet?

If you need to specify default values ​​for creating new forms, you can override the empty_form property of the empty_form object:

 class MyDefaultFormSet(django.forms.models.BaseInlineFormSet): @property: def empty_form(self): form = super(MyDefaultFormSet, self).empty_form # you can access self.instance to get the model parent object form.fields['label'].initial = 'first name' # ... return form class DetailsInline(admin.TabularInline): formset = MyDefaultFormSet 

Now, every time you add a new form, it contains the source data that you provided. I tested this on django 1.5.
