- Update gridfs.rst to make it clearer that you should save the Document hosting the GridFSProxy after calling .delete() or .replace() on the GridFSProxy
- updated GridFSProxy.__str__ so that it would always print both the filename and the grid_id. This should improve debugging
Since there is a .save() method on EmbeddedDocument, you could be tempted to attach a pre_save event to an EmbeddedDocument (#1720). This update is an attempt to make this clearer.
