Instance Method Details

#_default_attributes ⇒ Object

ActiveRecord overrides _default_attributes (attributes.rb:253) with a version that reads the @default_attributes class ivar and opens a connection to build the AttributeSet. Same per-Ractor fix as above: cache in IES so workers never read/write the shared class ivar.
