Django how to save formset with a foreign key?

Question

I have two models employee and child(Enfant) related by a foreignkey, like models.py

  class Enfant(models.Model) : id_emp = models.ForeignKey(Employee, on_delete=models.CASCADE) id_Enfant=models.IntegerField(blank=True,primary_key=True) 

views.py

 form = EmployeeForm(request.POST or None) form_EnfantForm_formset =formset_factory(EnfantForm, formset=EnfantFormSet) if request.method == 'POST' if form.is_valid() : #pdb.set_trace() new_employee=form.save() EnfantForm_formset0 = form_EnfantForm_formset.save(commit=False) EnfantForm_formset0.employee= new_employee EnfantForm_formset0.save() 

I need to save employee record and enfant records

Answer 1

Saving a formset returns a list of instances. You have to iterate over this list and assign the field:

instances = form_EnfantForm_formset.save(commit=False)
for instance in instances:
    instance.employee = new_employee
    instance.save()
