I'm working on a django app for a site that requires an image gallery. Since the site is fairly simple I chose not to use a database. In the gallery part, I have a loop in the view that reads all the image files from the image folder, and sends them to the template, where they are rendered inside a loop:
import os
from django.shortcuts import render_to_response
def show_pics(request):
"""sends a list of files to the view"""
folder = '/static/images'
files = [os.path.join(folder, f) for f in os.listdir(folder) if '.jpg' in f]
return render_to_response('gallery.html', { 'files' : files })
and the template:
<div id="gallery">
{% for file in files %}
<img src="{{ file }}" class="gallery-image" />
{% endfor %}
</div>
This works great in development mode (I set up url to serve static files under '/static/'), but when I upload to my webserver, the images aren't rendered. When I look at the rendered html, this is what I get:
<div id="gallery"> </div>
I made sure the static url works on the webserver by trying to access some random picture through the static url - http://mysite.com/static/images/some_image.jpg, and the css is definitely working (don't worry, I'll use a separate server for static files later). I should probably say that the production server is running python2.5 whereas I'm running 2.6 (both have django 1.1). Any thoughts?
It's safe to assume files is empty in template. You can confirm this by putting {{ files }} in the template and see what it prints. Most likely, nothing.
However, there are few possible problems with this:
folder = '/static/images'
files = [os.path.join(folder, f) for f in os.listdir(folder) if '.jpg' in f]
First, the path os.listdir takes is not the path from your document root, but from file system root. So if you do ls /static/images on the server, what does it show?
And as a minor thing, I'd prefer using f.endswith('.jpg')
