Instance Method Details

#dump(object) ⇒ Object

‘recordable_object` `object` will be a plain `Hash`. However, due to recent [memory optimizations](git.io/fjeYv), when coming from `recordable_object_changes`, it will be a `HashWithIndifferentAccess`.

Parameters:

  • object (Hash | HashWithIndifferentAccess) —

    • Coming from

    where_object_changes no longer supports reading YAML from a text
    column. The old implementation was inaccurate, returning more records
    than you wanted. This feature was deprecated in 8.1.0 and removed in
    9.0.0. The json and jsonb datatypes are still supported. See
    discussion at https://github.com/paper-trail-gem/paper_trail/pull/997

#where_object_condition(arel_field, field, value) ⇒ Object
