*Hi Andy, somehow my earlier post got deleted--must have hit the wrong button or something. So I'm reposting it below...*
Thanks for posting on the forum about this... I added the S3 bucket info to the documentation, but didn't think to test deleting files from it. After trying it out a little bit ago, I got the same result as you did. What is happening is that the db resource is deleted, but Django hits an error while trying to delete the actual file on S3 (that's why the redirect didn't work). You'll see that the files you were trying to delete still exist in your bucket. I was able to fix it up, drawing mainly from this question <http://stackoverflow.com/questions/5372934/how-do-i-get-django-admin-to-delete-files-when-i-remove-an-object-from-the-datab> (see the second answer, and its comments). It will be easy for you to do in this one case, but will require some more info in the documentation, and ultimately a modification in the arches code to accommodate S3 storage. For now, *carefully* head into your virtual environment, and open up this file: ENV/lib/python2.7/site-packages/arches/app/models/models.py. Be sure to back it up before you do! Around line 433 is a function called auto_delete_file_on_delete(). In that function, you'll see a line that says "if os.path.isfile(instance.val.path):" That line is causing a server error, because instance.val doesn't have a path property when you use S3 storage (it has a url property). To make the fix, replace the contents of the function with this (note that the same first line is used): if instance.val: try: if os.path.isfile(instance.val.path): os.remove(instance.val.path) except: storage, name = instance.val.storage, instance.val.name storage.delete(name) Now it'll still try the old method, but when it comes across an error (a.k.a. "exception") it'll skip to the new code that is necessary for dealing with S3. This is really a hack, not a fix, but if you are careful about the indentation I think you'll be able to manage just fine. Also, if you are using a text editor like notepad++, be sure that you are using 4 spaces (not tab) to make the indentation (4 spaces per indent). Good luck and thanks again for posting!
