Create view with more models - django

Question

hi everyone I have a doubt with the use of forms and models.
I have to create a code that creates records in multiple tables and I don't know how to do it.
my goal is to create a page where I can enter all the data and when I save it creates the various tables filled in with the data provided by the user.
I'm a beginner I still have to learn the mechanism well =)
forms.py
from django import forms
from .models import Schede, DatiGruppi, Gruppi
class CreaSchedaForm(forms.ModelForm):
nome_scheda = forms.CharField(
required = True,
label ='Nome scheda',
widget = forms.TextInput(
attrs = {
'class': 'form-control',
'placeholder' : 'nome scheda',
'autocomplete' : 'off'
}
)
)
data_inizio = forms.DateField(
label='Data inizio',
widget = forms.DateInput(
attrs= {
'type': 'date',
'class': 'form-control',
'placeholder' : 'data inizio'
}
)
)
data_fine = forms.DateField(
label='Data fine',
widget = forms.DateInput(
attrs= {
'type': 'date',
'class': 'form-control',
'placeholder' : 'data fine'
}
)
)
class Meta:
model = Schede
fields = ['nome_scheda','data_inizio','data_fine']
class CreaDtGruppoForm(forms.ModelForm):
giorni_settimana = forms.ChoiceField(
choices = DatiGruppi.giorni_settimana_scelta
)
dati_gruppo = forms.ModelChoiceField(
queryset = Gruppi.objects.all(),
empty_label = "-",
required = True
)
class Meta:
model = DatiGruppi
fields = ['giorni_settimana', 'dati_gruppo']
views.py
#login_required
def creaScheda(request):
if request.method == "POST":
form = CreaSchedaForm(request.POST)
if form.is_valid():
scheda = form.save(commit = False)
scheda.utente = request.user
scheda.save()
else:
form = CreaSchedaForm()
context = {"form": form}
return render(request, "crea_scheda.html", context)
