python 3.x - Django 1.9: How to make a dynamic form? -

i have model called course:

class course(models.model):    number_of_semesters = models.positiveintegerfield()    field = models.charfield(max_length=30)    qualification = models.foreignkey(qualification, on_delete=models.cascade) 

i trying form in can input many courses user wants webpage. how this?

i know old one, recommend use django rest framework. although kind of tricky @ first, can use viewsets , serializers multiple objects , save them in database @ once. (btw, though used api's can substitute normal django views viewsets , use them standard).

i know not asked, have been developing in django while , haven't been able use formsets in clean way save n objects without knowing n @ first.

if decide go proposal, recommend read following:

• viewsets

• serializers (they same djangoforms)

• nested serializers (for rendering/creating/linking foreignkey instance)

  # serializer rest_framework import serializers  class qualificationserializer(serializers.modelserializer):     class meta:         model = qualification         fields = (             # insert fields here, form         )  class courseserializer(serializers.modelserializer):     qualification = qualificationserializer() # nested serializer     class meta:         model = course         fields = (             'number_of_semesters', 'field', 'qualification',         )
