How to retrieve content of a document?
by Luke Tymowski 29 Jun '00

29 Jun '00

Hello, Yet another question. I've gone through the DTML Reference Guide but couldn't find the answer. How do I display the content of a DTML Document through a query? For example: <dtml-with Document> <dtml-in "objectValues(['DTML Document'])" size=3 sort=id> <dtml-var id> <dtml-var title><br> </dtml-in> </dtml-with> Displays the document's name and title. But how do i display the content of that document within that query? I apologise if it's obvious. thanks, Luke

ProxyPass Problems
by Baker, Dennis [sjmr] 29 Jun '00

29 Jun '00

I'm having a problem with getting ProxyPass and SSL to work. I followed the How-to on Using Apache with ZServer, and unfo's How-To on Apache+ZServer+SSL. And my setup is nearly identical to the one listed on the howto. I have my main site in the root of my Zope Setup, and My SSL site is in a subdirectory of the root called SecureSite. After setting up the ProxyPass Directives in Apache (I have the httpd.conf section attached below) and Adding the SiteRoot objects on Zope I can access the main Site at http://mysite.org, but if I try to access https://mysite.org my web browser hangs until it times out. Also, it becomes impossible to browse the SecureSite Folder unless I delete the SiteRoot Object. It appears to be some kind of Apache issue, however I can't figure out why it won't connect, the directives are almost identical to the ones on the Howto.

OT: MS Outlook sucks
by Wilkinson Charlie E 29 Jun '00

29 Jun '00

...but you already knew that didn't you? First, an apology for previously sending MIME/html crap to the list, even after being told about it and after I thought I had it turned off, and another apology for this OT message while I'm at it. I think I've got it now. Using OL2k(CW) here, and I had set "plain text" everywhere I could find to set it. After visiting the Zope mailing list archives today, I was alarmed to find that I was *still* sending out MIME/html attachments. (A hearty thanks to the list members for not beating me up about this.) I checked the messages in my Sent box and these very same MIME/html attachement messages were listed as having been sent in plain text. Grrr... After much bitching, whining and research, I stumbled across what is possibly a fix. It seems that OL2k requires Outlook Express for some of its functionality, especially some aspects of handling SMTP (Internet) e-mail. I've never used OE for anything (on purpose), but I fired it up and checked the format for sending messages. It was set to html. It's now set to plain text. So maybe, just *maybe* its fixed now. (If it's not, then I've got some more bitching and whining to do...) I'm hoping this info might help anyone else here who may be having this problem.

ZODB/FSSession TransactionError

Funny though, I fired up the original Zope and immediately used <dtml-var SessionUID> which gave me a KeyError - understandable since I had not started FSSession yet. Realizing this I did a <dtml-call FSSession> and Voila - it worked without having to remove any session files. Thanks for the help, Brian

Creating PythonMethod from ZClass constructor/method.
by Jeff Hoffman 29 Jun '00

29 Jun '00

Hello, Using Zope 2.2b3, I am trying to create a PythonMethod from the constructor of my ZClass and keep getting an authorization dialog. In my MyZClass_add method, I have: <dtml-with "MyZClass.createInObjectManager(...)"> <dtml-call "manage_addFolder(id='testFolder')">  <dtml-with "manage_addProduct['PythonMethod']"> <dtml-call "manage_addPythonMethod( this(), 'testMethod', 'Test Method', 'self', 'pass' )"> </dtml-with> </dtml-with> Every pemutation I have tried gives the same result: an Unauthorized exception. Adding the Python Method by hand works fine, as does adding one using the following URL: http://localhost/sandbox/myInstance/manage_addProduct/ PythonMethod/manage_addPythonMethod?id=foo&title=bar&... If there is one thing I am weak on in Zope, it's permissions. I am assuming there is something wrong with the way mine are set up, but I have no clue what the correct solution is. I haven't had the time to try another Python product, but I am guessing that this problem is not specific to Python Methods; I believe I would run into this same situation trying to add an instance of any python product to my ZClass instance. Anyone have an idea? --Jeff --- Jeff K. Hoffman 704.849.0731 x108 Chief Technology Officer mailto:jeff.hoffman@goingv.com Going Virtual, L.L.C. http://www.goingv.com/

Have you seen Steve Alexander's reply to my post? I'm relatively new to Zope development (though with a fair amount of experience in Python), so I'd welcome the insights that others more experienced than me would bring.

Re: [Zope] DTML question
by Luke Tymowski 28 Jun '00

28 Jun '00

Hello, > <dtml-in "PARENTS[0].objectValues(['DTML Document'])" size=3 sort=id> should > work, no? No. This works on my production server, which runs Zope 2.1.14. <dtml-with history> <dtml-with 2000> <dtml-in "objectValues(['DTML Document'])" size=3 sort=title reverse> <dtml-var sequence-item><br> </dtml-in> </dtml-with> </dtml-with> But if I try that same code on 2.2b2 it doesn't work. If the subfolder is down 1, then size=1 works, but size=2 returns everything. If the subfolder is down 2, then size=1 works, size=2 works, but size=3 returns everything. By down 2 I mean like the example code above (folder I want to query is two levels down). Maybe it's a 2.2 bug? Luke

Re: [Zope] Problem with > 1 ZCatalog search on same page

You must understand, how batching works: "sequence-query" is the query string with any "query_start" parameter removed. A "dtml-in" uses the "query_start" parameter to decide where to start displaying the sequence (if not told otherwise with a "start=" argument. If you have several "dtml-in" on the same page, you need several start parameters, one for each "dtml-in". You can use the "dtml-in" argument "start" to tell it which variable should be used. The only remaining thing is to get a query string from QUERY_STRING that no longer contains unwanted "start=..." Elements. That is a task for a small external method. Dieter

There > are bound to be bumps from wjoever does it first. :) I use ZCatalog to catalog objects in the file system included into the Zope world via LocalFS. Minor patch to LocalFS needed. Everything works with the exception of proximity searches. Dieter

LocalFS and Cache Issues
by Rogerio Atem de Carvalho 28 Jun '00

28 Jun '00

I am using a combination of Zope to create and maintain a MySQL database. This database is full of images files so I decided to keep them outside MySQL for caching facilities. My question are: 1)image files referenced by LocalFS objects are cached by Zope? and 2)In this situation do I need to use Apache or only Zope+MySQL? regards, Rogerio Atem ------------------------------------------- E-mail enviado pelo servidor do CEFETCampos
