'ImageFieldFile' object has no attribute 'startswith'

[Daehee]

Hi, I'm using Django revision 8309. After I recently update to this
revision, it seems to break my code... Just wondering if anyone else
is having the same errors. I tried to roll back to a previous revision
but now the error seems stuck. Any help would be appreciated.

My code is:

{% load thumbnail %}
<div class="avatar"><img src="/media_files/{% thumbnail object.photo
180x180 crop %}" alt="{{ object.name }}'s photo" /></div>

The resulting error is:

TemplateSyntaxError at /people/daehee-park/
Caught an exception while rendering: 'ImageFieldFile' object has no
attribute 'startswith'

Hi,

See the page above:

You need to change the thumbnail package. Where you get a call to
self.filename, you should change to self.filename.name...

Best regards,

This would have been introduced in revision 8244, with the FileField
changes. Values for FileField are no longer raw strings, so they don't
have the startswith() method anymore. I was told last night that some
of the thumbnail apps rely on startswith(), and are thus breaking.

The solution here is to update the thumbnail app to use the value's
"name" attribute as the string it wants.

Thank you for the prompt responses. I am using sorl-thumbnail on
Google Code, and with your tips I found the solution to the problem
based on the FileField refactoring here: http://code.google.com/p/sorl-thumbnail/issues/detail?id=34
