#2386: AttributeError when mapping a subclass with database.session_mapper
------------------------+---------------------------------------------------
Reporter: chrisz | Owner:
Type: defect | Status: new
Priority: high | Milestone: 1.1.x bugfix
Component: SQLAlchemy | Version: 1.1
Severity: major | Keywords: sqlalchemy session mapper
------------------------+---------------------------------------------------
When using the new database.session_mapper mapping an old-style class or a
class that has already an `__init__` method, you will get an Attribute
error. This is because database.create_session_mapper directly checks
`__init__` and `__init__._session_mapper` which are not available in this
cases; getattr() should be used here (see also bug report
[http://groups.google.de/group/turbogears/browse_thread/thread/1f551664886208f2
here]).
Also, similar to SQLAlchemy, database.create_session_mapper should have a
keyword option `set_kwargs_on_init=True` for suppressing this feature.
