Generate input fields based on a input and store it properly

Question

I have a field called subjects that asks users how many subjects do they have and based on the number they input I want to generate the input fields of same number. And How and where do I store those inputs.

MODELS.PY

#this field will determine how many input fields to generate
subjects = models.IntegerField()

VIEWS.PY

def generate_forms(request):
    no_of_fields = request.GET.get('subjects')
    if no_of_fields:
        #generate other inupts
        #save it in the database

Besides generating the input, how do I save those data in the database. Thanks in advance

if you are using postgresql i suggest create a json column based on your subject input save each value as key value.. example if your number of subjects is 3 and you save something like this--> {'subject':1,'subject2':4,'subject3':3} or create a array column which saved as list.. like [1,2,3].. — Shiva

If you use postgres you can use django postgres specefic models fields(Like ArrayField).django specefic fields documention

For another databases you can create model for your subjects and for each subject you can insert new data in Subject model.

class Subject(models.Model):
    desc = models.CharField(max_length=50)
    other_filed = models.ForeignKey(OtherModel)

def generate_forms(request):
    other_field = 1
    subjects = request.GET.get('subjects')
    if subjects and subjects != '':
        for subject in subjects:
            Subject.objects.create(desc=subject, other_field=other_field)
