Hello all, I'd love you to give me your opinion and some help about what follows. I just downloaded Zope to my machine (MacOs X!!) and I'm an old style mac user. Now, I promised I'd have tried to realize a small solution for monday morning. I want a Zcatalogue to index some objects on the base of a property. This property is the name of the file BUT the extension, for example: code2.html property: code2 code88.html property: code88 and so on. That's because I want Zope to search for files whose code CONTAINS a given string. As far as I can tell, the standard machinery that comes with Zcatalogue searches on the files names ONLY with exact corrispondence, since the type of the file name property is ... well I don't remember. The point is I thought to give each file with a property of the right type so Zope could search adhering to my wishes. Am I right? Now these files are really a lot. Some users upload them to an ftp folder and I should have a script that adds the property to each file when it lands in my folder (AND fill it properly). How do I do this? I looked at the Folder API but I didn't find a way to detect a file arrival. Should I use a Zclass instead? And how? In the meantime I keep editing those files manually but I admit this makes me feel quite dummy. thanks so much for ANY hint Bye Catonano
