def table_primary_keys(table_name, include_parent_keys = IsRails71OrLater, schema_name: "")Returns the primary key columns of the given table. By default it will only return the columns that are not part of the primary key of the parent table (if any). These are the columns that are considered the primary key by ActiveRecord. The parent primary key columns are filtered out by default to allow interleaved tables to be considered as tables with a single-column primary key by ActiveRecord. The actual primary key of the table will include both the parent primary key columns and the 'own' primary key columns of a table.
