Instance Attribute Details

#base_table_name ⇒ Object (readonly)

where_clauses is compiled against this join's join_table_name (the joined-to table). base_where_clauses, on the other hand, is compiled against base_table_name (the joined-from table). The latter is used for the case where the source table polymorphically belongs_to the joined-to table and the type column (foreign_type) lives on the source table.
