Re: [Modeling-users] Bug report with dynamic

[Sebastien B. <sbi...@us...>]

    Hi Erny,

  Thanks for reporting, the pb. here is that build() does
not accept a PyModel yet. This should be fixed!! Could you please fill a bug
report? Thanks.

  Now in the meantime you can have it work this way:

>>> from Modeling.PyModel import Model, Entity, AString
>>> from Modeling import dynamic
>>> m=Model("TheModel")  # a PyModel.Model
>>> m.version='0.1'  # This is mandatory!!
>>> e=Entity("Person",properties=[AString("name")])
>>> m.entities.append(e)
>>> m.build() # Builds a Model.Model and stores it in 'component'
>>> model=m.component # get the corresponding Model.Model
>>> dynamic.build(model)
>>> import TheModel
>>> TheModel
<module 'TheModel' (built-in)>
>>> from TheModel import Person
>>> Person
<module 'TheModel.Person' (built-in)>
>>> from TheModel.Person import Person
>>> Person
<class 'TheModel.Person.Person'>


...given that you apply the included patch ;) which fixes the incorrect way the
modules and classes where represented (as string)

(I'll integrate this into the CVS main trunk)

-- Sébastien.
