How to get thumbnail in python code in version 3.2.5 of sorl thumbnail?

The documentation of sorl thumbnail still refers to the get_thumbnail function, but this doesn't exist in v.3.2.5. (cannot import name get_thumbnail)

For the life of me, I can't find any reference to what this function was changed to, or how to generate a thumbnail in the python code of this version of sorl. Any advice?

Well, a few weeks ago I discovered I actually solved this problem before and I even wrote a short blog post about it without remembering, - smacks head. If it's only the URL you're after, you can do this:

from solr.thumbnail.main import DjangoThumbnail

img = imageObject # a normal image url returned from an ImageField
size = (100,100) # any tuple 
img_resize_url = unicode(DjangoThumbnail(img, size))

It's a bit hackish, but it's better than Chris's solution in the sense that you can call any thumbnail size, without needing to adapt the extra_thumbnails field. That being said, I do find his solution cleaner in the sense that there are no internal imports from sorl required, but both ways should work.

In my particular case, I've used an ThumbnailField with extra_thumbnails defined:

class SomeModel(models.Model):
    # other kwargs omitted for clarity
    image = ThumbnailField(extra_thumbnails={
                           'inline_preview': {'size': (600,400)},
                           'small_thumb': {'size': (75,75), 'options':['crop', 'sharpen']})

The image field will have a dict of the images defined by the extra_thumbnails option as an attribute named, surprisingly, extra_thumbails:

somemodel_instance.image.extra_thumbnails['inline_preview']
