Django] Saving multiple images by formset doesn't work - django

Question

I'm trying to save multiple Images and his parent's data together on the same template.
I have one parent's model(to save normal data) and child's model(to save images). In this case, saving parent's data is working very well. but images are not work.
There isn't any error message.
//model
class QuotationPanchok(models.Model):
whose = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE)
title = models.CharField(max_length=50, help_text='', default='')
many = models.IntegerField(default='1', help_text='')
design = models.CharField(max_length=3, choices=(('yes', 'yes'), ('no', 'no'),))
sian = models.CharField(max_length=3, choices=(('yes','yes'), ('no', 'no'),))
havefile = models.CharField(max_length=3, choices=(('yes','yes'), ('no', 'no'),))
deadline = models.DateField(blank=True)
addressto = models.CharField(max_length=50, default='', help_text='')
fulltext = models.TextField(max_length=150, blank=True)
status = models.CharField(max_length=7, choices=(('not','not'), ('finish', 'finish'),), default='not')
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(auto_now=True)
def __str__(self):
return self.title
class ImagesForQuotation(models.Model):
whose = models.ForeignKey(QuotationPanchok, on_delete=models.CASCADE)
image = models.ImageField(upload_to='images/', blank=True, null=True)
def __str__(self):
return self.whose.title + " Image"
// views
def quotation_create(request):
ImageFormset = modelformset_factory(ImagesForQuotation, fields=('image',), extra=4)
if request.method == 'POST':
form = QuotationCreateForm(request.POST)
formset = ImageFormset(request.POST or None, request.FILES or None)
if form.is_valid() and formset.is_valid():
post = form.save(commit=False)
post.whose = request.user
post.save()
for f in formset:
try:
photo = ImagesForQuotation(whose=post, image=f.cleaned_date['image'])
photo.save()
except Exception as e:
break
return redirect('index')
else:
form = QuotationCreateForm()
formset = ImageFormset(queryset=ImagesForQuotation.objects.none())
context = {
'form': form,
'formset': formset,
}
return render(request, 'quotationapp/quotation_create.html', context)
//forms
class QuotationCreateForm(forms.ModelForm):

def __init__(self, *args, **kwargs):
super(QuotationCreateForm, self).__init__(*args, **kwargs)
for field_name, field in self.fields.items():
field.widget.attrs['class'] = 'form-control'
//template(quotation_create.html)
{% block content %}
<form action="" method="post" enctype="multipart/form-data">
{% csrf_token %}
{{ form.as_p }}
{{ formset.as_table }}
<input type="submit" class="btn btn-primary" value="">
</form>
{% endblock %}
How can I solve this problem?
