I am a newbie to both zope and python so i would > need explicit instructions if there is a solution. Are you really sure, you want this? Unless you use HTTPS (or another secured transport), your passwords are send with each request almost in plain form (if you use Basic Authentication, Zope's default). It is not too difficult to snif network traffic. In the above mentioned setup, your Zope passwords are not very secure. If Zope and Unix passwords are identical, your Unix passwords are neither... I definitely would not want to have this. If I would, I would look for the PAM module (there is a Python wrapper, but it requires root privileges). Alternatively, I would use a PTY (pseudo terminal) and automate 'passwd'. Dieter

I think, you have (at least) two options: 1. install a working ZDiscussion product 2. if this is impossible: empty the current definition of "manage_beforeDelete" in "Products/ZDBase/ZDiscussions.py" line 195 (replace its content by "pass"). Enter your folder, delete the ZDiscussion objects, and then get rid of ZDiscussion altogether. Dieter

Uploading images - no image!
by Etienne Labuschagne 04 May '01

04 May '01

Hi there The Python Method (not external Python Method!) below must upload an image after being given the id, title and filename (on the client computer). This should work the same way as the management interface based image uploading. Somehow, this function causes the image to be created, but is seems to contain no image data (you cannot view the image). What am I doing wrong? (self is passed as the only parameter. id, title and file are set in the calling form) id = self.REQUEST['id'] title = self.REQUEST['title'] file = self.REQUEST['file'] self.manage_addProduct['OFSP'].manage_addImage(id,file,title) return "Your image is uploaded."

writing dtml on zope.org
by ethan mindlace fremen 04 May '01

04 May '01

Folks, I'm trying to get a feel for how important it is for you to be able to write DTML on zope.org. I feel like zope.org originally served as a place for you to try out zope and a place to learn about it. It gradually aquired a collaboration side with the fishbowl. Now I feel that zope.org's primary purposes are collaboration and education. The tryout feature has been largely surpassed by the free and for fee zope hosting that is availiable. How do you feel about it? -- ethan mindlace fremen zopatista community liason

database design question
by Arkaitz 04 May '01

04 May '01

Hi all, I am starting to design a web app, which will have a database consisting of 5000 to 10000 restaurants, which could potentially grow, but not much more. I'm a newbye to Zope,and initially my idea was to keep all the data in a MySQL DB, and access it from Zope. I need to do some very flexible queries and searches on the DB, and I've found that Z SQL Methods get quite awkward easily. I am thinking now about a pure-Zope (ZOBD) solution. I have thought about using a ZClass for each restaurant and keeping them organized in directories with the next hierarchy: County/City/Restaurant Is this a reasonable idea at all to do? I can write Python, and would like to avoid DTML for non-presentation tasks as much as possible. Also, I would need to be able to do queries of the style "give me restaurants that sell chinese food anywhere in this region/city". I appreciate any recommendation or resource that can help me make a good decision. TIA, Arkaitz.

\'s in ZSQL methods with Postgresql
by Mayers, Philip J 04 May '01

04 May '01

This: update tb1 set cl1=<dtml-sqlvar val1 type=nb>,who=<dtml-sqlvar "REQUEST.AUTHENTICATED_USER">,time=now() Called with: sqlmethod(val1='\') Fails with: Error Type: ProgrammingError Error Value: ERROR: parser: parse error at or near "loginname" update tb1 set cl1='\',who='loginname',time=now() Clearly the \ needs to be escaped. Is this Postgres specific? If so, why isn't the DA (ZPsycopg) quoting it?
