Hi,

i would like to generate all temp image sin a postsave command. How can i generate the images for a specific instance?

In case you are using ImageSpecField in your model, this could be a workaround:

from imagekit.cachefiles import ImageCacheFile

def generate_temp_images(obj):
  for attr in dir(obj):
    try:
        val = getattr(obj, attr)
        if isinstance(val, ImageCacheFile):
            val.generate(force=True)
    except:
        pass

As a note, the value of fields with ImageSpecField type are determined by ImageSpecFileDescriptor descriptor returning ImageCacheFile objects. So, we can use the value of these fields to generate our temp files.
