by

1👍

I implemented using inlineformset_factory
forms.py

...
from django.forms import inlineformset_factory

...
ImagesFormSet = inlineformset_factory(
    Post,
    PostImages,
    fields=("image",),
    extra=4,
    max_num=4,
    widgets={
        "image": forms.FileInput(attrs={"class": "form-control col-md-4 col-sm-4 d-inline"}),
    },
    labels={
        "image": "",
    },
)

and in my views.py send ImagesFormSet with get_context_data as

from .forms import UpdateBlogForm, ImagesFormSet

...
class BlogUpdateView(generic.UpdateView):
    model = Post
    form_class = UpdateBlogForm
    success_url = "."
    template_name = "blog/dashboard_components/blog_dashboard_eidtpost.html"

    def get_context_data(self, **kwargs):
        context = super(BlogUpdateView, self).get_context_data(**kwargs)
        context["images_form"] = ImagesFormSet(instance=get_object_or_404(Post, id=2))
        return context

and finally accessed ImagesFormSet as images_form in my template.
