python 3.x - How to use PermissionRequiredMixin in FBV?

Question

I am thinking about how I can use PermissionRequiredMixin in FBV.(I have used the same in CBV and it is working as expected). Please find the FBV(here need to implement permission). I don't want to use @login_required()

@login_required() This will check only if the user is authenticated or not.

def delete_viewgen(request,PermissionRequiredMixin,id):
    oneuser=ShiftChange.objects.get(id=id)
    permission_required = ('abc.add_shiftchange',)
    oneuser.delete()# delete
    return redirect('/gensall')

I am getting ERROR : missing 1 required positional argument: 'PermissionRequiredMixin'

CBV Case where it is working fine.

class ShiftChangeUpdateView(PermissionRequiredMixin,UpdateView):
    permission_required = ('abc.change_shiftchange',)
    login_url = '/login/'
    model=ShiftChange
    fields='__all__'

In CBV it is working fine and if user is not having change permission it is giving 403 Forbidden how to implement same in FBV and also how to customize 403 Forbidden message.

Thanks!

On function based views you would use decorators, in your particular case permission_required decorator

@permission_required('abc.change_shiftchange', raise_exception=True)
delete_viewgen(request,id)
