Can not show thumbnails when deploy on linux #13

Open eromoe opened 9 years ago

eromoe commented 9 years ago

Problem in files_widget/views.py

    return HttpResponse(json.dumps({
        'success': True,
        'imagePath': path_to_file,
        'thumbnailPath': render_to_string('files_widget/includes/thumbnail.html', locals()),
    }))

render_to_string('files_widget/includes/thumbnail.html', locals())

return u'' on ubuntu 14.04 but working on windows 7 x64.

I am using pycharm remote debuging, though it can not debug into sorl.thumbnail(pydev debugger: warning: trying to add breakpoint to file that does not exist: /root/d:/python27/lib/site-packages/sorl_thumbnail-12.2-py2.7.egg/sorl/thumbnail/templatetags/thumbnail.py (will have no effect)). So I don't know what cause this problem, please check it.

OK, I find the path mapping seems can make me debug into thumbnail.

Missing lib.... I spent three hours and get this... I should have checked app.log at first. How idiot am I....

But I still can not solve this problem, http://stackoverflow.com/questions/8915296/python-image-library-fails-with-message-decoder-jpeg-not-available-pil not work...
