Great!
Another issue, with "contains" this time:
----
from sqlalchemy.types import UserDefinedType
class Geometry(UserDefinedType):
class comparator_factory(UserDefinedType.Comparator):
def contains(self, other):
return self.op('~')(other)
from sqlalchemy import Table, Column, MetaData
lakes = Table('lake', MetaData(),
Column('geom', Geometry)
)
print str(lakes.c.geom.contains('POINT(1 2)'))
----
produces this error:
Traceback (most recent call last):
File "comparator_factory.py", line 18, in <module>
print str(lakes.c.geom.contains('POINT(1 2)'))
File "/home/elemoine/src/sqlalchemy/lib/sqlalchemy/sql/operators.py",
line 375, in contains
return self.operate(contains_op, other, **kwargs)
File "/home/elemoine/src/sqlalchemy/lib/sqlalchemy/sql/expression.py",
line 2204, in operate
return op(self.comparator, *other, **kwargs)
File "/home/elemoine/src/sqlalchemy/lib/sqlalchemy/sql/operators.py",
line 571, in contains_op
return a.contains(b, escape=escape)
TypeError: contains() got an unexpected keyword argument 'escape'
I should be able to override "contains", no?
