Hi,
I am just wondering if it is possible to allow a declarative object to
have some of its properties comparable as if they were ClauseElements.
I know I'm not explaining myself terrifically well here, but consider
the following property:
@property
def is_visible(self):
return (self.enabled and not self.is_deleted)
This can clearly be mapped quite easily to SQL expression
`Klass.enabled == True & Klass.is_deleted == False`
Is this something that is possible? I know that it is possible to use
a custom PropComparator to make these queryable, but for things that
be so directly represented by an expression, is there a way to make
that available?
