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?

Question about cache management
by Oliver Bleutgen 04 May '01

04 May '01

Hi zopistas, I'm currently trying to tune a site for production use. Now I'm thinking about how to best implement caching. My problem is that esp. the first two levels of the site are dynamically created from pulling together summary information from zclasses further down, and these "summary" pages all come from one index_html via acqusition. i.e. root folder index_html content folder content_folder_1 some zclasses content2_folder_2 some zclasses ..etc... So using bobobase_modification_time for the http-header isn't optimal I guess. Has anybody found a nice strategy to cleverly handle this kind of situation? Another question: Does anybody know how the RAM Cache Manager decides to purge an object? Is that just done by setting the "cleanup intervall" Btw: While doing testing I compared the RAM Cache Manager to apache's mod_proxy and to no cache at all. I got (on a PII 350 +64Meg) no cache: approx. 8 hits/sec Ram Cache: approx.: 50 hits/sec Apache+proxy approx: 500 hits/sec I know the reasons, but I found it nonetheless interesting. cheers, oliver

Zope as Portal Server
by dave＠kovach.com 04 May '01

04 May '01

Hi - Was researching something for work and was curious if anyone had any thoughts as to how ZOPE could be used as a PORTAL SERVER? Portals being all the craze(!) in the enterprise-land - seems as if ZOPE or even cooler a "vertical" version of ZOPE geared towards specifically the needs of deploying and maintaining an Enterprise portal... Any thoughts on the topic? or on the topic of ZOPE in the enterprise? or on the topic of Vertical versions of the ZOPE application?

Zope book error or version difference?
by Dennis Nichols 04 May '01

04 May '01

Zope Book .pdf fetched today says on page 258 >ObjectManager Constructor > >manage_addDocument(id, title) > >Add a DTML Document to the current ObjectManager But when I call manage_addDocument from DTML using in Zope 2.2.2, it actually adds a DTML Method (!) However, manage_addDTMLDocument(id, title) does add a DTML Document. Could be a change between 2.2.2 and 2.3.x or it could be an error in the book, in which case I thought I should point it out. Or maybe I should've skipped the beer with dinner. -- Dennis Nichols nichols(a)tradingconnections.com

Sorting mod.time with dtml-in?
by Kai Hofmann 04 May '01

04 May '01

I thought that I could simply sort by modification time withe the following: <dtml-in expr="subdir.objectValues()" sort="bobo_modification_time"> but as it seems I am to stupid to understand Zope/Python, because this does not work :( Any hints?
