sorl thumbnail about yawd-elfinder

Hello, can you please describe me the problem and the steps to reproduce it? I'm willing to investigate this asap since we have also used sorl-thumbnail in the past and might also need it in the future.

sorl thumbnail trying to find image in wrong path

    image = ElfinderField(optionset='image')

{% load thumbnail %}

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

No such file or directory: u'/path_to_my_project/media/llffim_ZGljdG9waG9uZS1idWcucG5n'

since item.image is an ElfinderField, you should do:

{% thumbnail item.image.url "100x100" as im %} instead of {% thumbnail item.image "100x100" as im %}

Please tell me if this fixes it for you, for more info see this section of the yawd-elfinder documentation:

Attempted access to '/media/images/my_image.png' denied.

sorry you are right, I see that sorl-thumbnail needs the absolute path instead of the url. I'll work on this as soon as possible, this fix must make it to the upcoming yawd-elfinder release this week.

Great, I'll wait.

This turns out to by a problem originating from sorl-thumbnail path detection algorithm. Since in some cases (like when using the default yawd-elfinder optionsets) the image url is relative, sorl thinks the argument is a file path instead of a url. To solve this create a custom filter like this (tested with sorl-thumbnail 11.12):

@register.filter('fullurl')
def fullurl(value):
return 'http://localhost:8000%s' % value

and then in the template code

{% thumbnail item.image.url|fullurl "100x100" as im %}

Of course you could optimize the filter for dynamically retrieving the current domain (if you use the django sites framework for example), the above is mostly for demonstration purposes. I don't think we should change something in yawd-elfinder, especially since we support multiple drivers that could return either relative or absolute urls. Hopefully this workaround is sufficient for you, for more info please see also
