Module: ChronoModel::Patches::Batches

Defined in:
lib/chrono_model/patches/batches.rb

Overview

Overrides the default batch methods for historical models

In the default implementation, cursor defaults to primary_key, which is 'id'. However, historical models need to use 'hid' instead of 'id'.

This patch addresses an issue where with_hid_pkey is called after the cursor is already set, potentially leading to incorrect behavior.

Notes:

  • find_each and find_in_batches internally utilize in_batches. However, in the upcoming Rails 8.0, this implementation will be insufficient due to a new conditional branch using enum_for.
  • This approach prevents specifying 'id' as a cursor for historical models. If 'id' is needed, it must be handled separately.
