You need to put the code for the class of object with the problems back in a state it was when things were last working. Changing meta_type, or worse still, trying to change the class of a persistent object will lead to much pain and suffering...

[Zope] Meta Type change
Hi How do I change the meta_type for an object in the ZMI from within Zope? An instance of a product I have built (inheriting from the the Folder Product) has become inaccessible after adding a lot of data. Essentially this is a product to archive text strings in a specific format and has worked fine for months. The problem has lead to corruption of the Data.fs file (and fsrecovery.py did not find anything to recover). I had a few backups from which I was able to recover the rest of the site and of the archive in a previous state, but had to go back 3 days. The backup from the day before the corruption does have the object in the ZMI tree, but now Zope thinks this is a normal Folder and when I try to access it, gives me attribute errors. When I attempt an XML download, although there are errors, I can see all the archived texts in the text that is appearing in my browser, however they are embedded in chaotic-looking text garbage, so I can't find a way to extract them by script. (And there are about 5000 missing texts, so copy and paste would take days!) I was wondering if I could just alter the meta_type for the object from within Zope, maybe through a python script and see if that makes the object accessible again. I can't find anything on how to change the meta_type for an existing object though. Any help very appreciated.

RE: [Zope] meta type?
Hallo Jason, you are on the right way. Try this in a folder: - - You'll get the names of all the metatypes in the current folder.

IMO, this should be done in each individual Zope server. IE, Zope shouldn't let you have two meta_types called 'News Item'. In combination with this, Products should list their meta types. -- Do not meddle in the affairs of sysadmins, for they are easy to annoy, and have the root password. ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
[Zope] Meta Type Registry
Is there a Product Builders meta-type registry somewhere? I can see things getting messed up in the near future as the number of products proliferates and meta-types start to clash. I've already seen weird interactions with products PSQL Input Wizard and ZNolk when both are installed I only got PSQL Input Wizard despite picking ZNolk from the drop down... At least if developers can register their meta-types then common meta-types won't clash for different products (I can see stuff like 'news item' and 'link' clashing all the time). Perhaps limit registration to developers who have published their product, I know this probably places an additional burden on the already heavily under seige developers, but I think some controls are going to be needed. -- Totally Holistic Enterprises Internet| P:+61 7 3870 0066 | Andrew Milton The Internet (Aust) Pty Ltd | F:+61 7 3870 4477 | ACN: 082 081 472 ABN: 83 082 081 472 | M:+61 416 022 411 | Carpe Daemon PO Box 837 Indooroopilly QLD 4068|[EMAIL PROTECTED]| ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
