I have a number of classes that subclass SQLObject as well as a mixin
class and now would like to jsonify them:
class myclass1( SQLObject, Mixin ):
.........
.........
class myclass2( SQLObject, Mixin ):
..........
..........
Since I have other classes that only subclass SQLObject I need to keep
the jsonify_sqlobject rule too but simply using @jsonify.when(
'isinstance( obj, Mixin )' ) raises an AmbiguousMethod exception
because my objects match both isinstance( obj, SQLObject ) and
isinstance( obj, Mixin ). After looking into RuleDispatch this is to
be expected because neither of the two conditions is more specific
than the other so an AmbiguousMethod exception is raised. So far I
understand the story.
When is not clear is how to work around it. How would I force
RuleDispatch to use my rule? I thought @jsonify.before( 'isinstance(
obj, Mixin )' ) would do the trick because the 'before' method would
come before the primary rule but it doesn't work, only the original
jsonify_sqlobject rule is run.
Any ideas?
