Hi I would like to distribute a ZClass Product from my Developing Server (Laptop ;) ) to my real public ZopeServer. I tryed the Distribution-Tab ... but I coudn't install it on my public Server. The tar.gz file contained a lib/python/Products/prodName directory and in that directory I found __init__.py, product.dat and version.txt . I copied the prodName directory (including the three files) to my lib/python/Products directory and restarted the server ... nothing happend ... So I transfered it via Import/Export - it worked and I started to run the website including some of my new objects. But now I developed further on my laptop and I would like to transfer the newer version of my product to the public server ... hmm ... well I tryed to play again the import export game ... this didn't worked, corse the MetaName was already inuse (well my Product which I like to update is using it - of corse) ... so I first deleted the Product on the public Server and imported the newer version - but now the new attributes are not available on the instances of the classes ... after a reboot of the server it worked properly * Now my questions. What have I done wrong in the proper way of distribution Zclass products? Is my "Export - delete - Import - reboot - Version" a valid way of doing it? Or do I wake up with a broken Database, crashed Webside, damaged installation? I'm sorry that I'm such a newbie ... but I really apriciate the help of this MailingList ...
