linking to images
by Fearless Froggie 25 Sep '02

25 Sep '02

One day I'll have zope all figured out . . . until then I have another dumb question! I have my own installation of zope at my ISP, and I just got two domains set up (cacheckup.com and bccheckup.com) pointing to: icabc.hurrah.com/cacheckup/ icabc.hurrah.com/cacheckup/bccheckup/bccheckup_current/ My images are delivered statically via apache and stored in "icabc.hurrah.com/images/", though I have localfs installed which I'm sure I can do lots of neat things with. The ISP is using apache rewrites to point my two domains to the correct places zope. My problem is that to link to my images I have to use the full path: "http://icabc.hurrah.com/images/....". What other options do I have to link to those images? A relative path would be much better idea, but I'm not sure how to make that work. I've read through the zope site and through the archives . . . but I'm not sure what the appropriate solution here would be. I assume that site access rules would be used to redirect requests stored in zope to the correct spot, I'm not sure though about stuff external to zope. Many Thanks!

Re: [Zope] hidden form fields-based identification

Hi Dieter, been busy a lot last two weeks, but learned a little more Zope as well. Thanks for your hint, I guess you meant the CookieLess product, anyway there is more than a choice available. The very problem now is HOW to use the url encoding feature effectively: What I think of now is to have all the HTML links in the pages (or objects) of my site dynamically rewritten (including auth info) on the server side BEFORE serving the page to the client. A kind of filter that performs url rewriting on-the-fly right before handling the page to the web server for response. Is DTML suited for this? Is it possible to have a page acquire a DTML header that, when rendered, performs url encoding of all the links in the page (calling some python Product's method like, say, CookieLess.encodeUrl() of course)?

Had I tried this ages ago, things would have been easier. However, there is a bug in the 2.6b1 make_instance script. It sets INST_HOME, not INSTANCE_HOME. I already filed a collector issue but consider yourself warned.

2 questions about dates in MS Access and Nested dtml-in calls
by McDonnell, Larry 25 Sep '02

25 Sep '02

Hi, I have two questions. The first is how do I generate an ZSQL Method when the variables are set to timestamp(19). I am looking to do the camparsion between date routine. I cannot change the variable to a different type. My next question is to do with nested dtml-in calls. I need to call two tables. One table has the detail information I need but the other has a few fields I need for header information. There are several fields that are in both, I was going to use invoice number. Currently, I have no input fields. I want to know if I can create a query without getting an keyerror for this field. <table width="100%" border="1"> <tr> <td> Customer </td> <td> Sales Order # </td> <td> P. O. # </td> <td> Part # </td> <td> Description </td> <td> Qty </td> <td> Serial Number </td> <td> Shipped Date </td> <td> Freight Carrier </td> <td> Waybill # </td> <td> # of Pkgs/Skids </td> </tr> <dtml-in lookup_gs_query2> <tr> <td> <dtml-var customer> </td> <td> <dtml-var order_no> <dtml-in lookup_gs_query3> <td> <dtml-var waybill> </td> <td> ,dtml-var date_shipped> </td> </tr> </dtml-in> </dtml-in> </table> Larry McDonnell Proton Energy Systems 50 Inwood Rd.

RE: [Zope] Passing Arguments to ZSQL Method from Python Script

Yes, that would work. But I am trying to do it without all of that. Dtml does this automatically, so I am not sure if I need to somehow add user to the REQUEST or what. I am pretty sure there is a way to do it. Thanks, Chris Bruce -----Original Message----- From: Meilicke, Scott [mailto:scott.meilicke@intp.com] Sent: Tuesday, September 24, 2002 3:59 PM To: Chris A.

by Sushil Bhattarai 25 Sep '02

25 Sep '02

HI Is there a way to parse a dynamic XML document in Zope. I'm calling a web service from zope. This web service returns XML. I want to parse this XML and put certain values in session. How can I parse XML I'm getting without physically saving it in Zope. By the way, can I dynamically save this XML in zope. I have XMLDocument and ParsedXML product but can't figure out a way to use these to solve my problem Sushil
