Instance Method Summary collapse
-
#dump(object) ⇒ Object

- #load(string) ⇒ Object
-
#where_object_changes_condition ⇒ Object
Returns a SQL LIKE condition to be used to match the given field and value in the serialized ‘object_changes`.
-
#where_object_condition(arel_field, field, value) ⇒ Object
Returns a SQL LIKE condition to be used to match the given field and value in the serialized object.
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`.

# File 'lib/paper_trail/serializers/yaml.rb', line 32 def where_object_changes_condition(*) raise <<-STR.squish.freeze 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.
