RE: [Zope] Searching for and displaying properties

RE: [Zope] Searching for and displaying properties

This add a property to an object but it has nothing to do with adding *metadata* to a ZCatalog instance. Please read the ZCatalog chapter of the Zope Book 2.7 edition. It carefully explains what *metadata* in the ZCatalog context means. The short version: a Zcatalog search returns *proxy*

RE: [Zope] Searching for and displaying properties

That's the official ZCatalog API. Otherwise find your objects through a catalog search and reindex them individually. I already did the reindexing just before the search and it didn't work. In any case, I may have found a workaround by using getObject(). According to

RE: [Zope] Searching for and displaying properties

manage_addProperty does not trigger recataloguing of the object even if its a subclass of CatalogAwareness. You should ? either call obj.reindex_object() or at least obj.index_object(), if your class has the CatalogAwareness-Mixin or you use the catalog API:

You must call manage_renameObject on the object *container*, passing the old name and the new name. Something like this: object = result[1] container = object.aq_parent container.manage_renameObject(object.id, object.id.lower()) Thanks Gabriel. I did exactly as you suggested, but ran

It is a known limitation of Zope, which has a set number of worker threads available to service user requests. If a worker thread blocks (e.g., waiting for MySQL), it is not able to do any work for other pending requests. You can tweak the number of threads in your zope.conf file, via the

Seems that all your Zope threads are busy (they're waiting for database response). There is no more threads to serve next requests so they're waiting (you may say that zope hangs in this situation, but in fact all it's threads are waiting for DB). You may install DeadlockDebugger product and
