I need to retrieve an optional number saved in DB , to a custom template tag i made . which to retrieve , a variable ( a photo ID ) included in this Gallery . within the gallery loop .

```
{% get_latest_photo   {{photo.id}}  %} 

```

How to accomplish that ?!

P.s : I know that can be done with inclusion tag , but in the present time how to make it fix this one !

Edit the template html file :

```
{% for album in albumslist %}

    {% get_latest_photo   photo.id  %} 
    {% for photo in recent_photos %}
<img src='{% thumbnail photo.image 200x80 crop,upscale %}' alt='{{ photo.title }}' />
    {% endfor %}
    {{ album.title }}
{% endfor %}

```

templatetag 

```
from django.template import Library, Node
from akari.main.models import *
from django.db.models import get_model

register = Library()

class LatestPhotoNode(Node):
    def __init__(self, num):
        self.num = num
    def render(self, context):
        photo = Photo.objects.filter(akar=self.num)[:1]
        context['recent_photos'] = photo
        return ''

def get_latest_photo(parser, token):
    bits = token.contents.split()
    return LatestPhotoNode(bits[1])

get_latest_photo = register.tag(get_latest_photo)

```

P.s Its working very well when i replace album.id (in {% get\_latest\_photo photo.id %} ) with a number which acts as an album id and retrieve the photo from .
