[ZODB-Dev] Broken objects problem.

[Matias Pansa]

Thanks for your response , i check the imports and seems to be ok but
still not working.

at this time i have every part of the app in the same folder and it's
working this way :


/appfolder/server.py --> Sever that listen for incoming connections ,
connects to zeo and store the data as "Posicion" class object.
/appfolder/Usuarios.py --> contains the definitions of some classes
including "Posicion" class , imported in every script that use it.
/appfolder/condb.py --> get a connection to zeo and retrieve the results
/appfolder/webapp.py --> the main flask app where the problem starts
trying to get the database objects via "condb.py".
/appfolder/vista.py --> it's a script that i use outside
flask/gunicorn app to check the data stored in zeo database , it uses
"condb.py" to get the                           objects from zeo
database , when i run this script i get the correct result , objects
of "Posicion" class are not broken  .

The problem only occurs inside flask/gunicorn app :


User ---> browser --->gunicorn/flask ---> get objects from zeo  # Here
the user just see broken objects of Posicion class , for example if i
try to do

                     Posicionobject.hour i get attribute error.

When i do :

(outside flask/gunicorn)

vista.py(to check stored data) --------> zeo --> database.fs  #
Everything works perfectly and i have no broken objects at all.



I'm not expert so obviously i'm losing something.

thanks , Matias.
