django_bulk_save.py - defer saving of django models to bulk SQL commits

When called, this module dynamically alters the behaviour of model.save() on a list of models so that the SQL is returned and aggregated for a bulk commit later on. This is much faster than performing bulk writing operations using the standard model.save(). To use, simply save the code as django_bulk_save.py and replace this idiom: for m in model_list: # modify m ... m.save() # ouch with this one: from django_bulk_save import DeferredBucket deferred = DeferredBucket() for m in model_list: # modify m ... deferred.append(m) deferred.bulk_save() Notes: * - After performing a bulk_save(), the id's of the models do not get automatically updated, so code that depends on models having a pk (e.g. m2m assignments) will need to reload the objects via a queryset. * - post-save signal is not sent. see above. * - This code has not been thoroughly tested, and is not guaranteed (or recommended) for production use. * - It may stop working in newer django versions, or whenever django's model.save() related code gets updated in the future.
