Revise paste Creating app photo

Tell me how I can modify my project my_holiday, so I can add additional logic with button Add Photo to the Place for example?

models.py

from django.db import models

class Place(models.Model):
    name = models.CharField(max_length=200)
    location = models.CharField(max_length=200)
    description = models.TextField()

def __str__(self):
        return self.name

class Photo(models.Model):
    image = models.ImageField(upload_to='place_photos/')
    places = models.ManyToManyField(Place, related_name='photos')

def __str__(self):
        return f"Photo {self.id}"

views.py

class PhotoCreateView(CreateView):
    model = Photo
    form_class = PhotoForm
    template_name = 'photo_create.html'

def form_valid(self, form):
        place_id = self.request.GET.get('place_id')
        place = get_object_or_404(Place, pk=place_id)
        form.instance.place = place
        return super().form_valid(form)

class PhotoEditView(UpdateView):
    model = Photo
    form_class = PhotoForm
    template_name = 'photo_edit.html'

class PhotoDetailsView(DetailView):
    model = Photo
    template_name = 'photo_details.html'

                    {% endfor %}
