    <p>I have a Django web application that accesses and manipulates several server filesystems (e.g. /fs01, /fs02, etc.) on behalf of the user. I'd like to present thumbnails of images on those filesystems to the user, and thought sorl-thumbnail would be the way to do it. </p> <p>It seems though that the images must be under MEDIA_ROOT for sorl-thumbnail to create thumbnails. My <code>MEDIA_ROOT</code> is <code>/Users/me/Dev/MyProject/myproj/media</code>, so this works:</p> <pre><code>path = "/Users/me/Dev/MyProject/myproj/media/pipe-img/magritte-pipe-large.jpg" try: im = get_thumbnail(path, '100x100', crop='center', quality=99) except Exception, e: exc_type, exc_obj, exc_tb = sys.exc_info() print "Failed getting thumbnail: (%s) %s" % (exc_type, e) print "im.url = %s" % im.url </code></pre> <p>It creates the thumbnail and prints the im.url, as I'd expect. But when I change <code>path</code> to:</p> <pre><code>path = "/fs02/dir/ep340102/foo/2048x1024/magritte-pipe-large.jpg" </code></pre> <p>It fails with:</p> <pre><code>Failed getting thumbnail: (&lt;class 'django.core.exceptions.SuspiciousOperation'&gt;) Attempted access to '/fs02/dir/ep340102/foo/2048x1024/magritte-pipe-large.jpg' denied. </code></pre> <p>Is there a way to solve this? Can I use sorl-thumbnail to create thumbnails as I'd like to under these other filesystems (e.g. /fs01, /fs02, /fs03, etc.)? Is there a better approach?</p> <p><strong>Update.</strong> Here's the full stack trace:</p> <pre><code>Environment: Request Method: GET Request URL: http://localhost:8000/pipe/file_selection/ Django Version: 1.4.1 Python Version: 2.7.2 Installed Applications: ('django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.sites', 'django.contrib.admin', 'django.contrib.admindocs', 'django.contrib.humanize', 'django.contrib.messages', 'pipeproj.pipe', 'south', 'guardian', 'sorl.thumbnail') Installed Middleware: ('django.middleware.common.CommonMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware') Traceback: File "/Library/Python/2.7/site-packages/django/core/handlers/base.py" in get_response 111. response = callback(request, *callback_args, **callback_kwargs) File "/Library/Python/2.7/site-packages/django/contrib/auth/decorators.py" in _wrapped_view 20. return view_func(request, *args, **kwargs) File "/Users/dylan/Dev/Pipe/pipeproj/../pipeproj/pipe/views/data.py" in file_selection 184. im = get_thumbnail(path, '100x100', crop='center', quality=99) File "/Library/Python/2.7/site-packages/sorl_thumbnail-11.12-py2.7.egg/sorl/thumbnail/shortcuts.py" in get_thumbnail 8. return default.backend.get_thumbnail(file_, geometry_string, **options) File "/Library/Python/2.7/site-packages/sorl_thumbnail-11.12-py2.7.egg/sorl/thumbnail/base.py" in get_thumbnail 56. source_image = default.engine.get_image(source) File "/Library/Python/2.7/site-packages/sorl_thumbnail-11.12-py2.7.egg/sorl/thumbnail/engines/pil_engine.py" in get_image 12. buf = StringIO(source.read()) File "/Library/Python/2.7/site-packages/sorl_thumbnail-11.12-py2.7.egg/sorl/thumbnail/images.py" in read 121. return self.storage.open(self.name).read() File "/Library/Python/2.7/site-packages/django/core/files/storage.py" in open 33. return self._open(name, mode) File "/Library/Python/2.7/site-packages/django/core/files/storage.py" in _open 156. return File(open(self.path(name), mode)) File "/Library/Python/2.7/site-packages/django/core/files/storage.py" in path 246. raise SuspiciousOperation("Attempted access to '%s' denied." % name) Exception Type: SuspiciousOperation at /pipe/file_selection/ Exception Value: Attempted access to '/fs02/dir/ep340102/foo/2048x1024/bettina.jpg' denied. </code></pre>

    1. COI think you should use a path relative to `settings.MEDIA_ROOT` instead of an absolute path. But the full stacktrace would be useful to make a precise answer.

    2. COI'm including the actual path just for illustration purposes. I could just as well have set `path` to `os.path.join(settings.MEDIA_ROOT, "pipe-img/magritte-pipe-large.jpg")`. Good idea -- I'll add the full stacktrace now.

    3. COTry just `"pipe-img/magritte-pipe-large.jpg"` instead of `os.path.join(settings.MEDIA_ROOT, "pipe-img/magritte-pipe-large.jpg")`. I think it will make the absolute path automatically.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
