sorl-thumbnail not working

Question

I have been trying for several hours now to get sorl-thumbnail working, but it just won't work.

The hard part is that it's not showing errors so I have no idea whats wrong. I followed the instructions to install it.

My full code can be found here: https://github.com/samos123/Samos-IT/tree/master/samosit

template: https://github.com/samos123/Samos-IT/blob/master/samosit/templates/projects/project_detail.html

{% load thumbnail %}
{% thumbnail object.image "100x100" crop="center" as im %}
    <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">
{% endthumbnail %}

view: https://github.com/samos123/Samos-IT/blob/master/samosit/projects/views.py

def detail(request, project_id, slug):
project = get_object_or_404(Project, pk=project_id)
imageurl = "/media/"+project.image.url
return render_to_response('projects/project_detail.html', {'object' : project, 'imageurl' : imageurl}, context_instance=RequestContext(request))

Thanks to sorl I can now finally see what the problem is. This seems to be the error: See the full error here: http://pastebin.com/0Yddt10N

Answer 1

I don't know about your view code but the first template code looks correct. Try setting THUMBNAIL_DEBUG = True and DEBUG = True in your settings for normal traceback.

Ekaterina

Ah now I'm getting the error. I will update my main post. Before I couldn't see the error. – Devine

I have never seen this before but it looks like a database error, make sure the datetime/date fields are correct. Flush/Drop database if you have to. – Ekaterina

I saw this in your settings: CACHE_BACKEND = 'db://cachetable'. I don't know who told you its a good idea for sorl-thumbnail, but its really not. Anyway this problem might be the caching timeout, seems that there is a bug? in django dbcache so that it cannot handle that large timeout, try setting THUMBNAIL_CACHE_TIMEOUT = 3600 * 24 * 365 (on e year should be enough :)) – Ekaterina

Actually the default was sys.maxint which is kind of brave and datetime can't handle more than 9999 years. This is fixed in the latest commit on github: github.com/sorl/sorl-thumbnail. Thanks! – Ekaterina

This did the trick: <code>THUMBNAIL_CACHE_TIMEOUT = 3600 * 24 * 365</code> but this is a hack? and its fixed in the latest commit if i understand correctly? Anyway thanks. Sorl: What do you suggest instead of: CACHE_BACKEND = 'db://cachetable' ? I created a Cache table in the database according to docs.djangoproject.com/en/dev/topics/cache/#database-caching, which was suggested by the documentation here: thumbnail.sorl.net/requirements.html#cached-db – Devine

sorl-thumbnail's cached-db uses a database for persistent key value storage but a cache will put a layer on top of that. This top layer cache should be fast, so memcached for example is a good choice. You can also use redis as a key value store which is persistent and fast. – Ekaterina

Answer 2

try:

<img src="{{ im }}" width="{{ im.width }}" height="{{ im.height }}">

Paronymous

I tried it but still didn't work, really have no idea what the problem is. I really followed the documentation step for step. Thanks for trying to help though! – Devine

Check you install output for PIL installation issues. On many systems, when installed under virtualenv, PIL won't find libjpeg or libz, and thus, won't support PNG or JPEG files. – Euphrates

Answer 3

Make sure you're using the latest 10.12 version and not the 3.2.5 one, cause your syntax belongs to the new 10.12 version.

See here the two available downloads: https://github.com/sorl/sorl-thumbnail

Clientage

I used pip install sorl-thumbnail to install the latest version. I installed it according to the 10.12 syntax. Guess this is not the problem But thanks will check it out! – Devine

I'm using 10.12, I double checked it today. :( – Devine

Answer 4

It happens when you don't do the migrate command after adding sorl-thumbnail to installed_apps.

Just try python manage.py migrate.
