What's the best practise to store images / files in blob storage
This post has NOT been accepted by the mailing list yet.
I'm trying to create simple model with a file and an image attribute stored in the blob storage but found it almost impossible with current Grok release (1.4) and available extensions.
mebrok.form is broken, dolmen.blob (widgets) are using different forms framework which I didn't make work easily and I also failed with plone.namedfile due to dependency conflicts and a few others packages which I found are outdated at all.
I was so surprised that I can't make it work even without blob storage easily - it seems a lot have been changed so even using zope.app.file isn't the way.
So my question is if I missed something and there is an working example or if the best way is for example to update megrok.form or if there is even anybody having working code for file/image field stored in the zodb or bettter in blobs.
