Line Wrap and the Zope Community?
by Ron 22 Nov '01

22 Nov '01

Does Zope hard code carriage returns? I'm new to Zope. I'm following a zillion links to Zope community pages, doc's, HOWTO's, etc. and finding on many pages I either have to scroll horizontally or increase the horizontal size of my browser (Galeon, though I've loaded a few pages in Netscape 4.7 with the same results) to view all the text. Is this a limitation of Zope, an error imposed by the page designers, a design flaw in my browser OR WHAT? I mean... it's almost 2002 and something this simple and basic is still an issue? Please, someone tell me about a browser setting I've failed to notice since... (whew, caught myself in time and deleted the rest of this rant...) Thank you for any help or enlightenment to this irritation. -Ron

import / export between versions
by sanket j deshmukh 22 Nov '01

22 Nov '01

Hello friends, please help me. I have Zope 2.3.3 on my localhost and zope 2.4.0 is installed on my companys server. Now if i try to export files from my localhost(zope2.3.3) onto server (zope2.4.0) it doesn't work. i guess because of difference in version. Is there any solution to this problem besides upgrading to zope 2.4.0 ?? Thanks.

There are a number of references to the "searchable-object interface specification." Such as in Appendix B of the Zope Book. Does this specification exist anywhere?

RE: [Zope] [ZClass constructor question]: How can I copy objects into my container class?
by Simon Brogden 22 Nov '01

22 Nov '01

Hi Jim, Nice one! I went with the script approach and called from within the: <dtml-with productname.createInObjectManager(REQUEST['id'], ...)> All worked fine. Thank you. I looked at the other approaches you mentioned: <dtml-with newitemname> ... </dtml-with> & <dtml-call "newitemname.init()"> Much headscratching. What do I replace 'newitemname' with to get it to work? I tried "REQUEST['id'].init()" and several variants but get "Attribute errors" about "init". The only way I can get stuf fto work is when the init() call is made inside the "<dtml-with productname.createInObjectManager(REQUEST['id'], ...)>" block. I guess I need help figuring out how to look-up the name of the item that's contained in the var 'id' and use it as part of the call.

upload to localFS with form
by Frank Löffler 22 Nov '01

22 Nov '01

Hi, localFS is: doku I want to upload to a subfolder: test. Using these codes won't work: <dtml-with "doku.test"> <dtml-call expr="manage_addProduct['OFSP'].manage_addFile (name, file=file)"> </dtml-with> or <dtml-call expr="doku.test.manage_addProduct['OFSP'].manage_addFile (name, file=file)"> or <dtml-with "doku.test"> <dtml-call expr="manage_addFile (name, file=file)"> </dtml-with> or <dtml-call expr="doku.test.manage_addFile (name, file=file)"> What's wrong ? In zope it works just fine but it doesn't if the subfolder is in an localFS. What does: manage_addProduct['OFSP'] mean, got it from a another posting. cu, Frank

ZGDChart: Data Method tab is empty and other questions
by Panos Hilaris 22 Nov '01

22 Nov '01

Greetings to everybody! I have installed ZGDChart-0.6.1.babel.tgz in the Products. I am using Zope 2.4.1 in linux. I create ZGDChart objects in folders, but the ``Data Method'' tab is always empty, so it seems I can not bind the chart to some query, even though appropriate queries exist in the same folder as a ZGDChart object. The gdchartdemo example (imported from file gdchartdemo.zexp of older release: ZGDChart-bin-0.5.tar.gz) seems to work fine (charts appear as expected), but the ``Data Method'' tabs are again empty, so there is no obvious way how graphs are binded to queries. Another problem: I can not use the example at: http://www.zope.org/Members/teyc/ZGDChart/ZGDChart-example.gz/view (it does not seem to be a gzip file). And one more general question: Is there a way to specify a runtime query for the graph? Something like a zgdchart_runtime_query argument at the argument of the chart method, just like the zgdchart_runtime_title argument for changing the title of the graph. In fact, it seems to me such that a method, i.e., specifying the data to be presented in the code, and not using the ``Data Method'' tab, is better for my purposes. Thanks in advance, Panos Hilaris

Some of them were in the old collector. I dont think it would be humanly possible to list them all. Its more than a few bugs which individually may be fixable... Zope's http layer simply wasnt designed with this kind of robustness in mind, and its only a small exaggeration to say that *everything* is wrong. Also, Im not sure its worth the effort. This isnt the only compelling reason for using a font-end proxy. Using a proxy makes this problem a non-issue, so why bother fixing it?
