Constant Summary collapse

KEYWORD_AREL_TABLE =

Rails main (8.2) made Arel::Table.new keyword-only.

Arel::Table.instance_method(:initialize).parameters.none? do |type, _name|
  %i[req opt].include?(type)
end
SQLSTATE_CYCLE =

The triggers raise with these custom SQLSTATEs, so translation does not depend on message wording.

SQLSTATE_CROSS_SCOPE =
