Feature

  • Handle func-based fields and allow expressions in upserts [Wes Kendall, 64458c5]

    pgbulk.upsert allows users to provide a pgbulk.UpdateField object to the update_fields argument, allowing a users to specify an expression that happens if an update occurs.

    This allows, for example, a user to do models.F('my_field') + 1 and increment integer fields in a pgbulk.upsert.

Api-Break

  • Initial release of django-pgbulk. [Wes Kendall, 7070a26]

    The initial release of django-pgbulk includes three functions for bulk operations in postgres:

    1. pgbulk.update - For updating a list of models in bulk. Although Django provides a bulk_update in 2.2, it performs individual updates for every row and does not perform a native bulk update.

    2. pgbulk.upsert - For doing a bulk update or insert. This function uses postgres UPDATE ON CONFLICT syntax to perform an atomic upsert operation. There are several options to this function that allow the user to avoid touching rows if they result in a duplicate update, along with returning which rows were updated, created, or untouched.

    3. pgbulk.sync - For syncing a list of models with a table. Does a bulk upsert and also deletes any rows in the source queryset that were not part of the input data.
