g'day.
i stepped on strange behavour (0.4 latest):
class AB is an assoc proxy, .myb pointing to B;
the clause
AB.myb == B.dbid
fails with NotImplementedError:
File "sqlalchemy/sql/expression.py", line 1191, in __eq__
return self.operate(operators.eq, other)
File "sqlalchemy/sql/expression.py", line 1315, in operate
return o[0](self, op, other[0], *o[1:], **kwargs)
File "sqlalchemy/sql/expression.py", line 1277, in __compare
obj = self._check_literal(obj)
File "sqlalchemy/sql/expression.py", line 1421, in _check_literal
return other.expression_element()
File "sqlalchemy/orm/attributes.py", line 53, in expression_element
return self.comparator.expression_element()
File "sqlalchemy/orm/interfaces.py", line 432, in expression_element
return self.clause_element()
File "sqlalchemy/sql/expression.py", line 1170, in clause_element
raise NotImplementedError()
NotImplementedError
these work (not the .property):
AB.myb.property == B.dbid
AB.myb == 3
AB.myb.property.direction is MANYTOONE
seems i'm missing something??
any idea or prepare a test case?
