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'

photo_create.html

{% extends 'base.html' %}

{% block main_content %}
    
Add Photo
    

        {% csrf_token %}
        {{ form.as_p }}
        Submit
    
{% endblock %}


photo_edit.html

{% extends 'base.html' %}

{% block main_content %}
    
Edit Photo
    

        {% csrf_token %}
        {{ form.as_p }}
        Update
    
{% endblock %}


photo_details.html

{% extends 'base.html' %}

{% block main_content %}
    
Photo Details
    
Image: 
    
Place: {{ object.place.location }}
{% endblock %}

travelogue_view.html

{% extends 'base.html' %}

{% block main_content %}
    {% if places %}
        
Total places: {{ places|length }}
        

            {% for place in places %}
            

                

                    
                    {% for photo in place.photos.all %}
                        
                    {% endfor %}
                
                
Location: {{ place.location }}
                
Category: {{ place.category }}
                

                    Details
                
                
                Add Photo
            
            {% endfor %}
        
    {% else %}
        
No places yet
    {% endif %}
{% endblock %}
