Problem with nested dtml-in
by Bill Welch 14 Aug '00

14 Aug '00

I'm having trouble with nested dtml-in. The outer ZSQL returns the coordinates of a zip code as zlat and zlong. The inner ZSQL takes zlat and zlong as well as Range and Otype as arguments. When I run it I get: Error Type: Bad Request Error Value: ['zlat', 'zlong'] If I hardwire the inner one with just zlat and zlong, I get: Error Type: Bad Request Error Value: ['Range', 'Otype'] If I hardwire the inner one with all four keyword arguments it runs fine. Here're the relevant lines from my DTML Doc: <dtml-in zipCoord> <dtml-var Range><dtml-var zlat><dtml-var zlong><dtml-var Otype> <dtml-in orgZipRadius> Trace line prints fine when all four arguments are hardwired or inner ZSQL is commented out.

Problem to access my DTML files
by Jarkko Veijalainen 14 Aug '00

14 Aug '00

Hi! I developed my project on Zope 2.1.6 on NT environment. Last week i installed Zope 2.2.0 on Solaris 8. i transferred my project to 'new' Zope. But when i try to access my DTML document comes authentication window. I can't authenticate it in any of my usernames. Traceback (innermost last): File /usr/local/Zope-2.2.0/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/Zope-2.2.0/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/Zope-2.2.0/lib/python/ZPublisher/Publish.py, line 171, in publish File /usr/local/Zope-2.2.0/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: email_accounts) File /usr/local/Zope-2.2.0/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: email_accounts) File /usr/local/Zope-2.2.0/lib/python/OFS/DTMLDocument.py, line 170, in __call__ (Object: email_accounts) File /usr/local/Zope-2.2.0/lib/python/DocumentTemplate/DT_String.py, line 502, in __call__ (Object: email_accounts) File /usr/local/Zope-2.2.0/lib/python/DocumentTemplate/DT_Let.py, line 147, in render (Object: resDTML="Imap('Authentication',REQUEST,1)") File /usr/local/Zope-2.2.0/lib/python/DocumentTemplate/DT_Util.py, line 337, in eval (Object: resDTML.cn) (Info: resDTML) File <string>, line 0, in ?

User information is different than my zope user. ex. i log into my Zope management as jarkkov (so that stays at my browsers cache, until i restart browser) i type in my login document '666666' and 'password', these values are submitted to another document called email_accounts, which uses external method with submitted parametres and return values into email_accounts document. Above error message is shown. in zope 2.1.6 environment it did'nt happen. I tied to create all kind of users on users folder and tried to give all permissions to anonymous user and tried to access anonymously thrue another browser, but nothing seems to work. This is essential that i can anonymously access to this DTML documents and submit any kind of values on my REQUEST. All the documents are on subfolder called testweb and i noticed that Zope 2.2.0, i have ownership in all documents and folders. testweb is owned directly by jarkkov (testweb/acl_users) and all documents in that folder. I can't remove ownership or can i? Is it the blocking my access anonymously to documents? What i have to do to make my project work on new Zope version? jarkkov

Using Zope as App Server for non http-Protocols
by Philipp Auersperg 14 Aug '00

14 Aug '00

We want to (mis)use zope as an application server servicing a proprietary non-http protocol for transmitting compressed data. Our idea is a specially written client that connects on a proprietary port to zope where a special product is listening and serving the request. Our question: How can I implement a product listening on a specific port and servicing requests and sending back binary (in our case compressed) data. But the product should of course be able to use the infrastructure of Zope (ODB,External methods,ZSQL methods...) Another question is how does the authentification work for such a non-http connection. Any hints? Thanks in advance Philipp Auersperg

Import broken by namespace conflict - fragile!
by Jason CUNLIFFE <jasonic＠nomadicsltd.com> 14 Aug '00

14 Aug '00

Hello This is a repost of a serious message I posted on friday. [The threaded version of this list is corrupted - my message content has been automatically replaced by another person's message, athough strangely, the gzip archive is ok.] ---------------------------------------------------------------------------- Please can someone help us understand how to avoid DTML method names conflicting with other zope objects with same name. For example using Zope export/import during recent site development to transfer work from local machines to the linux server broke sections of our site in a manner which was very hard to find. The reason we have finally traced to namespace conflict. We imported code which included calls to a local zope object named 'swf' for simple substitution. But suddenly our code did not work. It turned out that another object identically named 'swf' was an already existing 'folder' ..!! This is a very disturbing discovery, becuase it implies that one might have anywhere at anytime hidden or visible namespace conflicts emerging and vanishing with no control. We had thought that <dtml-with something></dtml-with> would avoid this. But it does not and may even cause it! It also implies that makes development of Zope sites across various machines very hit-or-miss Please help.. Exact code dump follows... 1. I have an original DTML template called 'objembedswf' in a folder named 'Flash4' <OBJECT ID='login' CLASSID='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' CODEBASE='http://active.macromedia.com/flash2/cabs/swflash.cab#version=3,0,0 ,0' WIDTH=<dtml-var width> HEIGHT=<dtml-var height>> <PARAM NAME='Movie' VALUE='<dtml-var swf>'> <PARAM NAME='Play' VALUE='false'> <PARAM NAME='Quality' VALUE='best'> <PARAM NAME='swLiveConnect' VALUE='true'> <PARAM NAME='menu' VALUE='false'> <EMBED NAME='login' mayscript='mayscript' SRC='<dtml-var swf>' swLiveConnect='true' WIDTH='100%' HEIGHT='100%' salign='t' quality='best' play='false' menu='false' TYPE='application/x-shockwave-flash' pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_ Version=ShockwaveFlash'> </EMBED> </OBJECT> 2. Below this my DTML file includes calls to this template like this: <dtml-with Flash4> <dtml-call "REQUEST.set('swf','login.swf')"> <dtml-call "REQUEST.set('width','100%')"> <dtml-call "REQUEST.set('height','100%')"> <dtml-var objembedswf> </dtml-with> 3. Here is the result of substitution returned in browser <OBJECT ID='login' CLASSID='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' CODEBASE='http://active.macromedia.com/flash2/cabs/swflash.cab#version=3,0,0 ,0' WIDTH=100% HEIGHT=100%> <PARAM NAME='Movie' VALUE='<Folder instance at 8557b00>'> <PARAM NAME='Play' VALUE='false'> <PARAM NAME='Quality' VALUE='best'> <PARAM NAME='swLiveConnect' VALUE='true'> <PARAM NAME='menu' VALUE='false'> <EMBED NAME='login' mayscript='mayscript' SRC='<Folder instance at 8557b00>' swLiveConnect='true' WIDTH='100%' HEIGHT='100%' salign='t' quality='best' play='false' menu='false' TYPE='application/x-shockwave-flash' pluginspage='http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_ Version=ShockwaveFlash'> </EMBED> </OBJECT> I draw you attention to the fact that <dtml-var swf> was supposed to be subsituted with 'login.swf', but instead became <Folder instance at 8557b00> ..ouch.. 4. The reason appears to be that there is a namespace conflict elsewhere in my Zope tree. As it turns out, we have a folder right under / called 'swf'. In fact it could be many places and still cause a conflict. This 'bug/feature' is the same under Zope 2.1.6, and Zope 2.2.0 in Win98se and LinuxRedhat. Is it something about <dtml-with> or perhaps our use of <dtml-call "REQUEST.set> which creates this unpredictable and confusing effect? Is this is a bug? As it stands it means is is very hard to have people working on separate sections of a Zope site because at any time they might be causing namespace collisions like this. In our case the effect was obvious - our swf files immedaitely woudl not display. But other voodoo could easily occur which migh not appear for some time. It provokes me to ask simply what is the search path priority of object acquistion in zope and how do you control it safely? Thank you - Jason Cunliffe

RE: [Zope] zcatalog -- returning context of hits on fulltext
by Jean Jordaan 14 Aug '00

Hi Toby > If you really do have a 67 page document, For the sake of the argument, that was page 67 of a 149-page document .. > it would be better to store each page in its own ZODB > object, and index each page individually. Well, the number of pages depends on the formatting .. but it might be an idea -- chunking the input, say a paragraph, or, better, a sentence at a time. I want to spend the absolute minimum time doing anything like that manually though. Content managers should be able to add a document without jumping through any hoops. So that chunking should be automatic. -- jean

Dunno if Catalog can do it either .. not even if I do include the fulltext in the MetaData Table. 'Cause the hit will have come from the indexed text, so it has no way of knowing *which* hit in the original fulltext it was .. right? -- jean

Squishdot upgrade HELP- screwy max posts behaviour
by sean＠horse101.com 14 Aug '00

14 Aug '00

I upgraded my 3.x version of Squishdot to 4.1 I followed all the instructions, but when I got to the part where you "push this button once" after the upgrade to 4, I got an error (so of cource I pushed it many times and now get the message that: Error Type: Index Exists Error Value: The index specified already exists). I hate to say it but I did not right the original error down. Maybe it was the same I was I get now...I don't know. Anyway, now I am having problems. I have not had a single post to the page (it seems like since my upgrade...but cannot be sure). I have added test articles with no problem but nothing new by others. Here is a hard fact illustrating part of my current problem: When I set the options to show 25 maximum posts on main page I get 8 displayed. When I set it to show 50, I get 16. WHAT IS GOING ON? Any help resolving this would be greatly appreciated. Have a look at it at http://www.dressage.to/forum/dressage --Sean

hi Zopers, In case this is very obvious (I'm RTFM'ing meantime) .. while hacking Squishdot's DTML, I did something to make 'leftbox_items' inaccessible to 'Anonymous': Unauthorized You are not authorized to access leftbox_items. in / , Anonymous has these permissions: Access contents information Add Comments Add Newss Add Postings Add ZWiki Pages Change ZWiki Pages Search ZCatalog Use Database Methods View any clue what's up? -- jean (running Zope 2.1.6 and Squishdot-0-4-1)
