From 8340006dd7ed34cf32bbb7f856397d1c7f13d295 Mon Sep 17 00:00:00 2001 From: Mike Bayer Date: Sat, 14 Oct 2006 21:58:04 +0000 Subject: - a fair amount of cleanup to the schema package, removal of ambiguous methods, methods that are no longer needed. slightly more constrained useage, greater emphasis on explicitness. - table_iterator signature fixup, includes fix for [ticket:288] - the "primary_key" attribute of Table and other selectables becomes a setlike ColumnCollection object; is no longer ordered or numerically indexed. a comparison clause between two pks that are derived from the same underlying tables (i.e. such as two Alias objects) can be generated via table1.primary_key==table2.primary_key - append_item() methods removed from Table and Column; preferably construct Table/Column/related objects inline, but if needed use append_column(), append_foreign_key(), append_constraint(), etc. - table.create() no longer returns the Table object, instead has no return value. the usual case is that tables are created via metadata, which is preferable since it will handle table dependencies. - added UniqueConstraint (goes at Table level), CheckConstraint (goes at Table or Column level) fixes [ticket:217] - index=False/unique=True on Column now creates a UniqueConstraint, index=True/unique=False creates a plain Index, index=True/unique=True on Column creates a unique Index. 'index' and 'unique' keyword arguments to column are now boolean only; for explcit names and groupings of indexes or unique constraints, use the UniqueConstraint/Index constructs explicitly. - relationship of Metadata/Table/SchemaGenerator/Dropper has been improved so that the schemavisitor receives the metadata object for greater control over groupings of creates/drops. - added "use_alter" argument to ForeignKey, ForeignKeyConstraint, but it doesnt do anything yet. will utilize new generator/dropper behavior to implement. --- lib/sqlalchemy/engine/base.py | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/sqlalchemy/engine') diff --git a/lib/sqlalchemy/engine/base.py b/lib/sqlalchemy/engine/base.py index 6d0cf2eb3..4ba5e1115 100644 --- a/lib/sqlalchemy/engine/base.py +++ b/lib/sqlalchemy/engine/base.py @@ -421,7 +421,7 @@ class ComposedSQLEngine(sql.Engine, Connectable): else: conn = connection try: - element.accept_schema_visitor(visitorcallable(self, conn.proxy, connection=conn, **kwargs)) + element.accept_schema_visitor(visitorcallable(self, conn.proxy, connection=conn, **kwargs), traverse=False) finally: if connection is None: conn.close() -- cgit v1.2.1
