When I try to access a specific mapped attribute the error below is thrown but only if I use a custom __eq__().
def __eq__(self, other): ''' ''' return self.aromatic_ring_id == other.aromatic_ring_id When I print the type of both, the 'other' class is 'symbol': <class 'credoscript.models.aromaticring.AromaticRing'> <class 'sqlalchemy.util.langhelpers.symbol'> Any ideas what went wrong? --------------------------------------------------------------------------- AttributeError Traceback (most recent call last) /home/adrian/<ipython console> in <module>() /usr/local/lib/python2.7/dist-packages/SQLAlchemy-0.7.2-py2.7-linux-x86_64.egg/sqlalchemy/orm/attributes.pyc in __get__(self, instance, owner) 166 return dict_[self.key] 167 else: --> 168 return self.impl.get(instance_state(instance),dict_) 169 170 def create_proxied_attribute(descriptor): /usr/local/lib/python2.7/dist-packages/SQLAlchemy-0.7.2-py2.7-linux-x86_64.egg/sqlalchemy/orm/attributes.pyc in get(self, state, dict_, passive) 422 value = ATTR_EMPTY 423 --> 424 if value in (PASSIVE_NO_RESULT, NEVER_SET): 425 return value 426 elif value is ATTR_WAS_SET: /home/adrian/Software/credoscript/models/aromaticring.py in __eq__(self, other) 48 ''' 49 print type(self), type(other) ---> 50 return self.aromatic_ring_id == other.aromatic_ring_id 51 52 def __ne__(self, other): AttributeError: 'symbol' object has no attribute 'aromatic_ring_id' -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
