[15:22:57] <erikrose> pje: please don't run away; I have a models question. :-)
[15:24:11] <pje> ok
[15:24:38] <erikrose> I'm hoping to make my O-R mapping framework pay attention to the isChangeable attributes of model features.
[15:24:58] <erikrose> (Right now, I just have the developer list a bunch of field names in a readOnlyFields tuple within the DM.)
[15:25:35] <erikrose> I'm trying to figure out how to traverse to the isChangeable attribute, given a DM instance and a feature name.
[15:25:50] <erikrose> Can I get there from here?
[15:26:27] <pje> No
[15:26:34] <erikrose> Crap.
[15:26:47] <pje> Unless the DM knows the class of all items it will return, of course
[15:27:01] <erikrose> Okay, what if I had `ob` (in peak.model parlance) too?
[15:27:03] <pje> because you need to go from element class->feature->isChangeable
[15:27:22] <pje> oh sure, that stuff is in the object's class's mdl_features
[15:27:35] <pje> you just want to get the feature object and look at its isChangeable
[15:27:47] <erikrose> Is mdl_features a dict? I forget...
[15:28:00] <pje> Fire up the interpreter and see.
[15:28:05] <pje> i.e., I forget too.  :)
[15:28:08] <erikrose> heh
[15:28:11] * erikrose fires.
[15:30:15] <erikrose> Okay, it looks like mdl_features just gives me a tuple of feature *names*.
[15:30:17] <erikrose> How do I get at the features themselves without having them resolve into their values?
[15:30:45] <erikrose> Oh, wait.
[15:31:15] <erikrose> It gives me the features after all.
[15:31:39] <erikrose> I still don't know how to get from feature-name to feature, though.
[15:32:10] <erikrose> I guess I could get both mdl_featureNames and mdl_features and make my own map. Can you think of a better way?
[15:48:05] <pje> getattr(ob.class, featureName)
[16:06:33] <erikrose> Mmm, delicious. Thanks.
[16:06:44] <erikrose> Thanks a whole lot.
[16:08:30] <erikrose> ob.__class__, you meant, aye?
[16:51:58] <pje> yeah
