Aw crap. And I thought I had tried that.
setting ajax=True does indeed work... I'm guessing that it's because it
creates a separate request whereas load without ajax uses the current value
of request.controller to decide which models to execute.
Anyway, problem solved. Thanks pbreit!
Also, why, if I may ask, do you advise against conditional models or
'premature optimization' as you put it? I guess there's the argument "if it
ain't broke, don't fix it".
The thing is I do some database queries within the conditional models file
(I omitted this in my example) which I don't think should run on every page
load, especially since this particular database is accessed by several
applications. Perhaps its still premature (the db traffic is low for now...
but that db is brand new and apps haven't been modified to use it as
opposed to LDAP).
