How to call django forms inlineformset into django templates - django

Question

i am new to django and learning some from stackoverflow. Now i am creating a website for post with images and title. I found ways to connect my two models (images and post) at https://stackoverflow.com/a/62158885/13403211. it is working fine when i add post from admin. But i want to know how can i add those inlineformset fields into my template for user to fill in.Does anyone knows??
Here is the code i found. I copy the same code in my app to try.
models.py
class Item(models.Model):
user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="items")
name = models.CharField(max_length=100)
class ItemImage(models.Model):
item = models.ForeignKey(Item, on_delete=models.CASCADE)
img = models.ImageField(default="store/default_noitem.jpg", upload_to=get_image_dir)
forms.py
from django import forms
from django.forms.models import inlineformset_factory
from .models import Item, ItemImage
class ItemImageForm(forms.ModelForm):
class Meta:
model = ItemImage
exclude = ()
class ItemForm(forms.ModelForm):
class Meta:
model = Item
fields = ["name",]
ItemImageFormSet = inlineformset_factory(
Item, ItemImage, form=ItemImageForm,
fields=['img'], extra=3, can_delete=True # <- place where you can enter the nr of img
)
views.py
class ItemCreateView(LoginRequiredMixin, SuccessMessageMixin, CreateView):
template_name = "items/add_item_form.html"
success_message = 'Item successfully added!'
form_class = ItemForm
def get_context_data(self, **kwargs):
data = super(ItemCreateView, self).get_context_data(**kwargs)
data['form_images'] = ItemImageFormSet()
if self.request.POST:
data['form_images'] = ItemImageFormSet(self.request.POST, self.request.FILES)
else:
data['form_images'] = ItemImageFormSet()
return data
def form_valid(self, form):
context = self.get_context_data()
form_img = context['form_images']
with transaction.atomic():
form.instance.user = self.request.user
self.object = form.save()
if form_img.is_valid():
form_img.instance = self.object
form_img.save()
return super(ItemCreateView, self).form_valid(form)
I have search on google and i did not find any related to this. Or am i doing wrong? Can someone help me?
