TransientObjectContainer.keys()
by Shannon -jj Behrens 14 Mar '03

14 Mar '03

Hi, I'm using Zope as an application server for some weird, non-Web-related stuff. TransientObjectContainer really matches my needs for a particular problem (the dict-like interface and the auto-delete feature are quite useful), but TransientObjectContainer has no keys() method. I can see why this is the case considering sessions, but it's something that I absolutely need for my application. I assume my options are: o Hack Zope and submit a patch. o Hack Zope and don't submit a patch, because it won't be accepted. o Figure out some (really inconvenient) way to store a list of keys in the TransientObjectContainer. o Don't use TransientObjectContainer, just use normal Zope objects. Use a cron job to implement auto-delete. I welcome your advice. Best Regards, -jj -- Hacker is to software engineer as Climbing Mt. Everest is to building a Denny's there.

Re: [Zope] anyone? Help getting the correct URL from absolute_url or portal_url
by Michael Havard 14 Mar '03

I found no reference to base href in the document. I don't set it and I don't see that ZOPE/CMF sets it either. here's the ZPT code that's generating the urls for the items <ul> <li tal:repeat="item items"> <a href="item_url" tal:attributes="href item/absolute_url"><img align="middle" border="0" tal:attributes="src string:${item/portal_url}/${item/getIcon}; alt string:${item/Type}; title string:${item/Type}"></a> <a href="item_url" tal:attributes="href item/absolute_url; title item/Description" tal:content="item/Title"> Title </a> </li> </ul> both absolute_url and portal_url when called within the frameset appear to get a reference to the parent frameset's host instead of the document's host. Are there other mechanisms in place to get the host name:port for a document? >From: J Cameron Cooper <jccooper(a)jcameroncooper.com> >To: zope(a)zope.org >Subject: Re: [Zope] anyone?

Right, but at least, it would help to have an article that would explain to eg. PHP or Perl users what the point is using a framework, and especially something Zope. Personnaly, just showing me that I won't have to stick an index.html (index.php) in each and every directory would probably be enough to convince me :-) >Many add-ons have their own lists.

Hi Rick, > Can you store a dictionary in a cookie? I've been trying and it keeps > barfing on me. If I set the dictionary in the REQUEST, it works just > fine, but if I set it as a cookie, and then try to reference it with > <dtml-var "cookie['key']"> if bombs with "sequence index must be an > integer". Dost it think it's a list? Do you need a dictionary, or can a list be useful too? On this case, you could send a coma delimited string and then use the split method to convert it to a list. You could also use more delimiters for example: a1,b1;a2,b2;...;an,bn and then split the string by the semi-colons. Then go through each element and split by the commas; However, this solution is not efficient nor elegant, but it could be an alternative. Again, as Geir said, you are limmited to 255 characters (not sure about this number) when working with cookies. You can also get rid of it by using this piece of code: http://www.zope.org/Members/gaaros/localcookies Regards, Josef

Can you store a dictionary in a cookie? I've been trying and it keeps barfing on me. If I set the dictionary in the REQUEST, it works just fine, but if I set it as a cookie, and then try to reference it with <dtml-var "cookie['key']"> if bombs with "sequence index must be an integer". Dost it think it's a list? TIA Rick

Yes we have done this purposefully. The main app is served from Silverstream java appserver (soon to be transitioned to Websphere :) ). All of our reference content is in ZOPE. It's an internal web application so users are limited in bookmarking (security/HIPAA issues) and the other reasons that frames don't make sense for the general web populace don't factor in for us. We have multiple instances of ZOPE running so unfortunately I can't hard code any urls. I have to rely on the CMF and ZOPE to return the correct path for images and items via the absolute_url property or whatever property will give the correct url. >From: J Cameron Cooper <jccooper(a)jcameroncooper.com> >To: zope(a)zope.org >Subject: Re: [Zope] anyone?

anyone? Help getting the correct URL from absolute_url or portal_url
by Michael Havard 14 Mar '03

14 Mar '03

I have a webserver running on host:8200 which serves framed content. On occassion it loads one frame with content from my ZOPE server running on host:8300. When the ZOPE frame loads the links and icons within it are broken because they show up as http://host:8200/item instead of http://host:8300/item. If I refresh the URLS get corrected. How do I get the correct URL the first time within a frameset? _________________________________________________________________ MSN 8 with e-mail virus protection service: 2 months FREE* http://join.msn.com/?page=features/virus

Rick, Just add something like: <dtml-var error_tb> To your standard_error_message, and the traceback will appear! Cheers, J.F. -----Original Message----- From: D.

A little while ago I upgraded our Zope servers to 2.6.0, and ever since then they stopped printing the entire error text when something happened. All I get now is the Error Type, Error Value and the little Troubleshooting Suggestions, but I have no idea what caused the error. I saw something earlier about the -D switch so I made sure that it was on in the 'start' script: exec /usr/local/Zope/bin/python $cwd/z2.py -D "$@" It wasn't a big deal until just recently when I started developing again. Things are bombing as they always do, but I'm having to guess at what's causing it. TIA Rick

Rick, Heh, I'm expriencing the same problem ... No more tracebacks, even in debug mode. I looked at the CHANGES.txt file, and didn't see anything mentionned about any changes in that behavior ... I've adjusted my standard_error_message for now to explicitely print the traceback, but now it appears in plain sight, not hidden in the page code :( I'm only developping/migrating right now, but this is one question I was going to ask later on :) J.F. -----Original Message----- From: D.
