[Modeling-users] Bug report with dynamic

[Ernesto Revilla]

Dear Sébastien,

going through dynamic, I'm really impressed. (I can learn a lot of stuff

from Modeling.PyModel import Model, Entity, AString
from Modeling import dynamic
m=Model("TheModel")
e=Entity("Person",properties=[AString("name")]
m.entities.append(e)
dynamic.build(m)

Traceback (most recent call last):
File "<interactive input>", line 1, in ?
File "C:\prg\python23\Lib\site-packages\Modeling\dynamic.py", line
153, in build
module_name=model.packageName()
TypeError: 'str' object is not callable

May be this is not a bug? The: m=Model("TheModel") should create an
empty model.

With regards,
Erny

In PyModel, line 971: v=apply(v.method, l), the function is evaluated
and substituted by it's value, so:
<function identity at 0x00FD2C70>('name',) will turn into
'TheModel' and this will be stored in object, so packageName is not a
function anymore.

Dear Sébastien,
going through dynamic, I'm really impressed. (I can learn a lot of
stuff from you). Although I still did no tests, here what seems a bug

from Modeling.PyModel import Model, Entity, AString
from Modeling import dynamic
m=Model("TheModel")
e=Entity("Person",properties=[AString("name")]
m.entities.append(e)
dynamic.build(m)

File "<interactive input>", line 1, in ?
File "C:\prg\python23\Lib\site-packages\Modeling\dynamic.py", line
153, in build
module_name=model.packageName()
TypeError: 'str' object is not callable
May be this is not a bug? The: m=Model("TheModel") should create an
empty model.

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.

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)>

Post by Ernesto Revilla

from TheModel import Person
Person

<module 'TheModel.Person' (built-in)>

Post by Ernesto Revilla

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.
