Is there a valid way of doing it? Right, subclassing IsDescription is not supported. Sorry, but I think that the only way is to do the repetition explicitly. Or, maybe you can use a NumPy dtype instead, that allows you to create table schemas more succinctly. -- Francesc Alted -- This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure ___ Pytables-users mailing list Pytables-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/pytables-users
[Pytables-users] Inheritance in
Hello, I have several different kinds of data tables, absolutely independent, defined as in the tutorial (http://pytables.github.com/usersguide/tutorials.html): from tables import * class SaltedPie(IsDescription): dough=Int64Col() baking=Float64Col() anchovy=Float32Col() class SweetPie(IsDesctiption): dough=Int64Col() baking=Float64Col() apple=UInt32Col() One, naively, saw the repetition and would want to do something like: class Pie(IsDescription): # All kind of pies dough=Int64Col() baking=Float64Col() class SaltedPie(Pie): anchovy=Float32Col() class SweetPie(Pie): apple=UInt32Col() but, when I try to set 'dough', I get: KeyError: 'no such column: dough' Of course, my approach is not correct. Is there a valid way of doing it? Thanks.
