Is it possible to find a file in filer with his number?

[Asakusa Tokugawa]

Hi,

I used the filer for more than a week and it works fine. But now, I have two problems.

1) 

Is it possible to find a file in filer with his number (e.g. 162, when the admin path is "/en/admin/filer/image/162/").

My problem is that I want to find the location (optimally the url for this file) by using the number.

The reason for this is that I want to provide images for download and they should not be opened directly in the browser but rather the save-dialog should 

appear. Does anyone have a code snippet for this problem or another idea?

2)

The other problem with the filer is in combination with the "easy thumbnails".

When I try 

thumb = get_thumbnailer('/media/filer_public/2013/06/11/399301_10151170147233531_2039543998_n_1.jpg')

I get the following error:

SuspiciousOperation at /en/admin/filer/image/162/getImage
Attempted access to '/media/filer_public/2013/06/11/399301_10151170147233531_2039543998_n_1.jpg' denied.

Info: The getImage method is in the views.py

When I use it with the hostname, I receive (e.g.: http://localhost:8000/media/filer...) that error:

InvalidImageFormatError at /en/admin/filer/image/162/getImage
The source file does not appear to be an image

Is the URL entered in the browser, the image is displayed.

But when I use the direct path (e.g. /var/www/mydjangoproject/....) it works perfect.

However, when I get the URL with "thumb.url", I get the path (which I had entered) instead the

URL (like http://localhost...) .

Does anyone has a hint for me?

Thx,

Asakusa

Hi Asakusa

You can get a specific File by id by getting it from the Database:

from filer.models import File

f = File.objects.get(id=42)

print f.url

I think get_thumbnailer assumes you are using a absolute path in your filesystem if the string starts with '/'. If you are using the default storage backend in filer, it might work if you provide the path relative to the root of the used storage backend ('filer_public/2013/06/11/399301_10151170147233531_2039543998_n_1.jpg').

django-filer file models behave like a regular file field when used with easy-thumbnails. So this should also work and will use the correct storage backends:

thumb = get_thumbnailer(File.objects.get(id=42))

Hi Stefan,

thank you very much for your quick feedback. I was able to solve both problems with "File.objects.get(id=42)".

Great forum, thx!
