Show collections in formset depending of user

[amikphoto]

Could you help me? Sorry to disturb you but maybe you can say what to
do in two words.
I have:

class CafeFormset(FormCollection):
    default_renderer = FormRenderer(field_css_classes='mb-3')
    cafe = CafeForm()
    cafe_images = CafeImageCollection()

Everything work fine and I have form collections with siblings in
CafeImageCollection class.

I decided to show cafe_images in forms depending of user.
What is the most correct way not to show cafe_images collection in CafeFormset.

If I understand your use-case correctly, you want to show cafe_images in your form only, if request.user is someone specific.

Yes, you're right

Just wanted to ask the best way to decide this problem. Where should I add the verification?

Try this way

form.py

class CafeFormset(FormCollection):
    default_renderer = FormRenderer(field_css_classes='mb-3')
    cafe = CafeForm()
    cafe_images = CafeImageCollection()

    def __init__(self, *args, **kwargs):
        super().__init__(*args, **kwargs)
        user = kwargs.get('user', None)
        if user
           cafe_image_queryset = CafeImages.objects.filter(user=user)
            self.declared_holders['cafe_images'].declared_holders['cafe_image'].fields['image'].queryset = cafe_image_queryset

views.py

class CafeView(...):
    ...

    def get_collection_kwargs(self):
        collection_kwargs = super().get_collection_kwargs()
        collection_kwargs['user'] = self.request.user
        return collection_kwargs

Let me know if you are facing any issue

Please share your entire views, models and forms then I can identify your issue

In one of my next versions, I will add methods get_min_siblings(request), get_max_siblings(request) and get_extra_siblings(request) just as the Django admin does.

I decided to add
if not self.request.user.is_authenticated:
context['form_collection'].initial.pop('cafe_images')
in get_context_data.
It works and I have no images on page depending of user. But I have add collection button on my page. I don't understand how to add context into formset renderer to control buttons for example.
