How To Dynamically Select Storage Option For Models.filefield?

Solution 1:

For what you're trying to do you may be better off making a custom storage backend and just overriding the various bits of S3BotoStorage. In particular if you make bucket_name a property you should be able to get the behavior you want.

EDIT:

To expand a bit on that, the source for S3BotoStorage.__init__ has the bucket as an optional argument. Additionally bucket when it's used in the class is a @param, making it easy to override. The following code is untested, but should be enough to give you a starting point

classMyS3BotoStorage(S3BotoStorage):@propertydefbucket(self):
        ifself._filename.endswith('.jpg'):
            returnself._get_or_create_bucket('SomeBucketName')
        else:returnself._get_or_create_bucket('SomeSaneDefaultBucket')

    def_save(self, name, content):
        # This part might need some work to normalize the name and all...self._filename = name
        returnsuper(MyS3BotoStorage, self)._save(name, content)
