Hello All, Im trying to read from the data.fs file plone product information like home attributes. Im doing this via ZEO using app.Control_Panel.Products.getObjectItems() This returns to me a set of (object ids, objects). Using the object I change the home attribute. When I restart the script the home attribute is the same as it was before. So the change did not take place in the database. Is there any way to check back in the retrieved object from data.fs? Thanks, Adit PS: I want to be able to modify the home attrib so I can change location of products even after theyre installed. AFAIK this is the only way to do it.

I don't know anything about plone, but... if you want to change a property of an item you can google for info on "manage_changeProperties", however I would be very careful about changing things in the Products folder!!! Do you want to change the product or an instance of a product/class? In which case you need to be accessing the instance object not the Product object. It makes no difference as to whether you are using zeo or not.
PS: I want to be able to modify the home attrib so I can change location of products even after theyre installed. AFAIK this is the only way to do it.
As I said I know nothing about plone, but changing the location of products after they are installed sounds like a good way to cause yourself some serious pain. ;-) Jonathan
Well, the home attribute cannot be changed using the manage_changeProperty since it is not exactly a property of the object. I tried that bt did not work.. Any way of putting an object back in ZODB? As to causing the pain the script would be useful if users can take a copies of the main dbs and use copies of their own products.

All you are writing does not make much sense. Please give a detailed description of your problem. I can't think of a problem that might require such an approach. -aj
Well, the home attribute cannot be changed using the manage_changeProperty since it is not exactly a property of the object. I tried that bt did not work.. Isn't this possible to set this attribute with extenal method for example?
Any way of putting an object back in ZODB? What do you mean by 'back in zodb'? back from where?
As to causing the pain the script would be useful if users can take a copies of the main dbs and use copies of their own products. I have no idea what you're talking about. You say that you want to copy data.fs between few zope intantces with different set of products?
Which class(?) has 'home' attribute? What do you mean by changing location of products and what are products for you? -- Maciej Wisniowski

This is really a plone question (regarding 'home attribute'), so you will probably get more help on the plone lists.
As to causing the pain the script would be useful if users can take a copies of the main dbs and use copies of their own products.
I clearly don't understand your objective then. By way of an example: i have an application which, when a user registers: creates a folder, creates an instance of a ZCatalog in that folder, populates the ZCatalog with some indexes and metadata, creates mysql db entries for the user and then emails a password to the user. The user gets their own folder, ZCatalog and mysql entries, but they are instances, not 'products'.
The problem that I encountered is that once the Plone Products are installed in data.fs and I move the same data.fs to another machine there is a constant message upgrade product in the plone site setup window. It occurs since the plone setup is unable to find the 'version.txt' file in the products directory. The home attribute can be changed to fix this. The problem seems to be of migration of data.fs and products to another machine. I was hoping to get any info on accessing objects in ZODB Thanks, Adit

This is definitely a plone issue and you should ask on plone lists. Jonathan

I see too possibilities: 1. You forgot the "import transaction; transaction.commit()" to make your changes persistent 2. The objects in "Control_Panel.Products" can be modified during startup for file systems based objects. -- Dieter
