u mean mapper's select_table=..? it's allways used because of
polymorphism.
today i tried those ABC things, found 2 issues:
- r3449 introduces some memory leak
- r3646 introduces some forever-recursion, goes like:
File "other/expression.py", line 355, in <module>
p2 = session.query( Person).filter_by( name= 'pesho').first()
File "/home/az/src/hor-trunk/sqlalchemy/orm/query.py", line 595, in
first
ret = list(self[0:1])
File "/home/az/src/hor-trunk/sqlalchemy/orm/query.py", line 620, in
__iter__
context = self._compile_context()
File "/home/az/src/hor-trunk/sqlalchemy/orm/query.py", line 873, in
_compile_context
value.setup(context)
File "/home/az/src/hor-trunk/sqlalchemy/orm/interfaces.py", line
483, in setup
self._get_context_strategy(querycontext).setup_query(querycontext,
**kwargs)
File "/home/az/src/hor-trunk/sqlalchemy/orm/strategies.py", line
553, in setup_query
value.setup(context, parentclauses=clauses,
parentmapper=self.select_mapper)
File "/home/az/src/hor-trunk/sqlalchemy/orm/interfaces.py", line
483, in setup
self._get_context_strategy(querycontext).setup_query(querycontext,
**kwargs)
File "/home/az/src/hor-trunk/sqlalchemy/orm/strategies.py", line
553, in setup_query
value.setup(context, parentclauses=clauses,
parentmapper=self.select_mapper)
... last two repeated ...
more details tomorrow
ciao
