Hi Antonio, To be honest, I didnt read all of your message because it was too long and wasn't very clearly worded. Sorry! I'd like to help but I usually only have the time to answer "bite sized" succinct emails from the maillist that don't require a lot of conceptual and physical setup. I imagine that other folks have the same issue. You might try to restate your problem in a shorter email. Cheers, - C Antonio Jesús Carrasco García wrote:
Hello again.
What´s the problem with my question? Is it very difficult? Nobody knows how to do it? Isn´t there any way to do it? Don´t you understand my english?
I need an answer. Or only a feedback to say: "Ok, Antonio. I have read your e-mail, but I don´t know the way to do it. Try another way to do it!."
Please, I need something. I´m becoming crazy.
Thanks. Antonio Carrasco www.grupoiud.com

Don´t forget. I´m spanish and my english may not be enough good. Have fun with this e-mail.
I´ve been a lot of time looking for documentation, studing it and trying to develop usefull things with ZODB. Here is my problem.
Well. I´m working in a Product in wich I use a ZODB to store data. I don´t use Data.fs, I´m trying to use the ZODB with my own file and collection. I have a product with this properties or attributes: id: the id of the instance. title: the title ZODBFile: The ZODB where the user want to store the data. I use this name to construct a FileStorage wich is like '<ZOPEDIR>/lib/python/Products/MyZProduct/var/' + ZODBFile + '.fs colection: The colection inside the ZODBFile.
When someone wants to add a MyZProduct instance, I show a form to fill this attributes. Well, the __init__ is like this: def __init__(self,id,title,ZODBFile,Colection): self.id=id self.title=title self.ZODBFile=ZODBFile self.Collection=Colection #Now try to connect to the database self.colection=FileStorage('<ZOPEDIR>/.......#and the name of the ZODBFile
This last line make the Zope to raise an Error Message in commit in Connection object. I don´t remember now (I´m not at work), but something like: "Attempt to store data from a remote database connection"
??????????. What´s the problem?. May my ZProduct inherit some other Class or ZClass to be able to store the data?.
Later I do a self.connection=db.open(). Another problem with this line. I can´t save in my class attributes this objects. The colection, neither the connection, and I need both to make the ZODB navigation, and the ZODB open and close methods.
If you need more information, I´ll post another more comprensive e-mail.
Thanks. Antonio Carrasco www.grupoiud.com PD: For spanish people I have written a How-To / Tutorial named crearUnProducto. www.zope.org/Members/rociana/misHowTo/crearUnProducto
