Added practically everything I wanted to have in except for updating columns. Needed to name the schema namespace as Orm::SchemaNs to avoid collision with the Orm::Schema class. - unit tests with great coverage - new schema constants - a new prefix_indexes and engine DB conncetion configurations Others: - IsModel tag - enhanced columnize in the BaseGrammar - used a new columnize logic in all grammars - new constants - new container utils class for joining containers - new DB::driver() getter for QSqlDriver - avoid possible crash in tests with pretend, added empty log checks - clang tidy, excluded to word from short variable names
