Hi.
I am quite new to Zope and currently try to create a BookClass ZClass Product. I came across several issues where you probably can give me some useful tips:
1. What is the difference between inheriting rom Object Manager and/or Folder.
Folder inherits from all kinds of other things, including ObjectManager. Basicly, if you want your object to be a container then subclass ObjectManager. If you want to look and walk and quack exactly like a Folder, use Folder.
2. My product will include Cover Images of the books. (a small and a large one). Whats the best way to implement this? I thought about creating emtpy images (smallcover and largecover), but I dont know how to ask the Objects if they contain something.
They have a getSize() method that returns the length of the Image (Files have this too).
Or should I just add the Images in my BookClass Instance programmatically?
Sure.
3. Wasn't their any web-client product for Zope so that I could retrieve content from the web directory and import it in Objects (like a Image) without having to upload it manually?
Yes, any automatable HTTP client will do. You might want to look into ZClient, or xmlrpclib, or httplib.
And the last one: Is their any special reason why FTP access doesnt work in the /Control_Panel/Products folder?
Yes, because we haven't implemented it.
All methods are empty their. I work with Emacs and ange-ftp is quite a good method to access content of Zope Objects.
Yes it is, I'd like to see this too. I don't think it would be too complex for someone to do, certainly FTP support is fairly trivial. For this you would need to mine the source.
Besides, if I change the content of a Object through the web interface, Zope seems to convert < > and " chars into < > "
I don't understand. Editing a DTML Method through the web should not munge it in this way.
I understand why, but is this really necessary. It seems as if nearly all textmode browsers (as lynx and emacs/w3) dont care about converting the entities back tto their corresponding characters.
