* slight cleanup for #498Mike Bayer2007-04-171-1/+4

* - column label and bind param "truncation" also generateMike Bayer2007-03-281-0/+1
| | | | | | | | | | | deterministic names now, based on their ordering within the full statement being compiled. this means the same statement will produce the same string across application restarts and allowing DB query plan caching to work better. - cleanup to sql.ClauseParameters since it was just falling apart, API made more explicit - many unit test tweaks to adjust for bind params not being "pre" truncated, changes to ClauseParameters
* - fixes [ticket:185], join object determines primary key and removesMike Bayer2007-03-271-1/+1
| | | | | | | | columns that are FK's to other columns in the primary key collection. - removed workaround code from query.py get() - removed obsolete inheritance test from mapper - added new get() test to inheritance.py for this particular issue - ColumnCollection has nicer string method

* - for hackers, refactored the "visitor" system of ClauseElement andMike Bayer2007-03-111-30/+31
| | | | | | | | | | | | | | | SchemaItem so that the traversal of items is controlled by the ClauseVisitor itself, using the method visitor.traverse(item). accept_visitor() methods can still be called directly but will not do any traversal of child items. ClauseElement/SchemaItem now have a configurable get_children() method to return the collection of child elements for each parent object. This allows the full traversal of items to be clear and unambiguous (as well as loggable), with an easy method of limiting a traversal (just pass flags which are picked up by appropriate get_children() methods). [ticket:501] - accept_schema_visitor() methods removed, replaced with get_children(schema_visitor=True) - various docstring/changelog cleanup/reformatting

| | | | | | | | skips already-quoted literals) - got mysql to have "format" as default paramstyle even if mysql module not available, allows unit tests to pass in non-mysql system for [ticket:457]. all the dialects should be changed to pass in their usual paramstyle.
* merged the polymorphic relationship refactoring branch in. i want to go ↵Mike Bayer2007-01-281-9/+5
| | | | | | | | | | | | | further on that branch and introduce the foreign_keys argument, and further centralize the "intelligence" about the joins and selectables into PropertyLoader so that lazyloader/sync can be simplified, but the current branch goes pretty far. - relations keep track of "polymorphic_primaryjoin", "polymorphic_secondaryjoin" which it derives from the plain primaryjoin/secondaryjoin. - lazy/eagerloaders work from those polymorphic join objects. - the join exported by PropertyLoader to Query/SelectResults is the polymorphic join, so that join_to/etc work properly. - Query builds itself against the base Mapper again, not the "polymorphic" mapper. uses the "polymorphic" version only as appropriate. this helps join_by/join_to/etc to work with polymorphic mappers. - Query will also adapt incoming WHERE criterion to the polymorphic mapper, i.e. the "people" table becomes the "person_join" automatically. - quoting has been modified since labels made out of non-case-sensitive columns could themselves require quoting..so case_sensitive defaults to True if not otherwise specified (used to be based on the identifier itself). - the test harness gets an ORMTest base class and a bunch of the ORM unit tests are using it now, decreases a lot of redundancy.

* - a fair amount of cleanup to the schema package, removal of ambiguousMike Bayer2006-10-141-239/+178
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

"foreign_key" will return the first element in the "foreign_keys" list/set or None if the list is empty. - added a user test to the relationships test, testing various new things this change allows

| | | | | | | | | | | | itself automatically based on if a parent schemaitem has a non-None setting for the flag, or if not, then whether the identifier name is all lower case or not. when set to True, quoting is applied to identifiers with mixed or uppercase identifiers. quoting is also applied automatically in all cases to identifiers that are known to be reserved words or contain other non-standard characters. various database dialects can override all of this behavior, but currently they are all using the default behavior. tested with postgres, mysql, sqlite. needs more testing with firebird, oracle, ms-sql. part of the ongoing work with [ticket:155]
