Question

I use an image gallery app on my website. At present I drop image files in a directory, and write img html tags for each image manually. Is it possible to make django create a list of files in the directory automatically, and send the json output to the gallery app, so that I can make javascript to generate <img> elements for each image files. Or, whenever gallery app is requested, can I directly make django to auto-generate <img> elements for each of the files in a directory.

here’s a bit of code for you:

views.py

import os 

def gallery(request):
    path="C:\\somedirectory"  # insert the path to your directory   
    img_list =os.listdir(path)   
    return render_to_response('gallery.html', {'images': img_list})

gallery.html

{% for image in images %}
<img src='/static/{{image}}' />
{% endfor %}
