ogrenci_dersi = models.ForeignKey('Ogrenci', null=True, on_delete=models.SET_NULL)
gonulu = models.ForeignKey('Gonullu', null=True, on_delete=models.SET_NULL)
devamsizlik = models.BooleanField(verbose_name="Devamsızlık Bilgisi",blank=True, default=False)
sinif = models.ForeignKey('SinifListe', null=True, on_delete=models.SET_NULL)

class Meta:
    ordering = ['-devamsizlik']
    verbose_name = 'Devamsızlık'
    verbose_name_plural = 'Devamsızlıklar'

def __str__(self):
    return self.gonulu.ad + '   ' + self.gonulu.soyad

here is my view: in view ı had been add required foreign keys for my table and then try to save coming post data from table form.

def ogrencidevamsizlik(request, id):
details = "hesabim/ogrenci-devamsizlik.html"
siniflar = SinifListe.objects.filter(gonullu__gonullu__email=request.user.email)
ogrenci = SinifDetay.objects.filter(sinif__gonullu__gonullu__email=request.user.email)
gonulu = GonulluDersleri.objects.get(gonullu__email__iexact=request.user.email, id=id)
gonulluler = Gonullu.objects.get(email__iexact=request.user.email)
ders = GonulluDersleri.objects.filter(gonullu__email=request.user.email, id=id)
devamsizliklar = SinifDetay.objects.filter(sinif__gonullu__gonullu__email=request.user.email, sinif__gonullu__id=id)
if request.method == 'POST':
    form = DevamsizlikDetayForm(request.POST, request.FILES)
    if form.is_valid():
        form.save()
        messages.success(request, 'Devamsızlıklar başarılı bir şekilde eklendi.')
        return redirect('gonullu-siniflar')
    else:
        messages.error(request, 'Devamsızlık bilgilerinizdeki zorunlu alanları eksiksiz doldurmalısınız.')
else:
    form = DevamsizlikDetayForm()
context = {'devamsizliklar': devamsizliklar,
           'gonulu': gonulu,
           'ders': ders,
           'form': form,
           'ogrenci': ogrenci,
           'siniflar': siniflar,
           'gonulluler': gonulluler}
return render(request, details, context)

and here is my table: in table ı try to add devamsizlik area for each student , gonulu , ogrenci and sinif ıd are already coming with views info but devamsizlik will submited by the gonullu so ı made a for loop for all student but when ı submit only first one can be submit thats the promlem
