Access problems

What has happened? Whatever resource I'm trying to access (including the management IF), I get this (running a 2.2.1 Zope on Unix) --------------- Attribute Error --------------- Traceback (innermost last): File /home/sites/site3/users/.../2-2-1/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /home/sites/site3/users/.../2-2-1/lib/python/ZPublisher/Publish.py, line 187, in publish File /home/sites/site3/users/.../2-2-1/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ApplicationDefaultPermissions) File /home/sites/site3/users/.../2-2-1/lib/python/ZPublisher/Publish.py, line 162, in publish File /home/sites/site3/users/.../2-2-1/lib/python/ZPublisher/BaseRequest.py, line 438, in traverse File /home/sites/site3/users/.../2-2-1/lib/python/ZPublisher/BaseRequest.py, line 514, in old_validation (Object: broken) AttributeError: (see above) TIA, Prost, Danny

How to use management tabs not for management
by Ron Bickers 02 Oct '00

02 Oct '00

I want to create create HTML pages with my own Zopish looking tabs that have nothing to do with Zope management. Is there a simple way to use manage_tabs for this, or do I need to make my own version of it? Everything I've tried gets me caught up in the Zope management system. _______________________ Ron Bickers Logic Etc, Inc. rbickers(a)logicetc.com

ZopeTime().Date() confusion
by Larry Albert 02 Oct '00

02 Oct '00

This is driving me batty. I am trying to do something very simple. I want a method to perform an update no more than once a day. I know there are other approaches to this issue -- such as using bobobase_modification_time, not to mention Xron -- but I would like to use a date property for reasons I won't go into here. I am using Zope 2.2.1. Every time the method updates, I update the date property called last_updated with this: <dtml-call "manage_changeProperties(last_updated=ZopeTime().Date())"> This gives me a date that appears to be accurate, such as 2000/10/01. Then, every time the page gets called, I want to check to see if it is time to call the method, so I use: <dtml-if expr="last_updated.isCurrentDay()"> don't update method <dtml-else> update method store new last_updated </dtml-if> This worked fine until, at the appointed hour, last_updated began to sense that even though it appeared to be "2000/10/01" (and even when I typed it in that way by hand), the time in Greenwich was actually more important to its sense of identity than was its appearance to me. So even when ZopeTime().Date() gave me 2000/10/01, last_updated.isCurrentDay() would evaluate to false(!). So the method would update every time the page was called. As a kluge, I changed my update command to <dtml-call "manage_changeProperties(last_updated=ZopeTime().toZone('GMT').Date())"> , which works, but causes the update to occur, I presume, at midnight GMT, rather than midnight here, which would be nicer (actually, I'd love to be able to control the precise hour updates should occur, but I can't figure out how to do that). This is also complicated -- but not relevantly, I hope? -- by the fact that the Zope installation seems to think the time zone is GMT+2 rather than GMT-5 (I'm in Texas). I understand that the previously counterintuitive use of strftime was changed for 2.2.1 -- but I am not using strftime, I am using Date() and isCurrentDay(). I've tried all sorts of combinations of switching time zones but succeeded only in confusing myself. So three questions: 1. Is there a better way to do this (still using a property called last_updated)? 2. Does the use of Date() and isCurrentDay(), etc. still switch everything to GMT, even though strftime was changed? If so, what is the list of methods that compare GMT, and which that compare the local installation time? 3. This appears to be a perfect example of something that should be very simple becoming needlessly complicated. Couldn't some more user-friendly ("beginner") time or date objects be implemented in DTML? Thanks for any help! Larry Albert lda(a)rice.edu

Limited file size editing...
by Curtis Maloney 02 Oct '00

02 Oct '00

Just curious... I've seen several times on this list people pointing out that the limit on the size of files you can edit in Zope via the web interface is a result of your browser. The sizes I recall were somewhere in the vacinity of 64K. I currently have a 470K file open for editing in Netscape 4.75 (under Linux). What are the limits on various browsers? Ignore me if you think this is too far off topic.... Curtis.

Allright, who broke acquisition?
by Timothy Wilson 02 Oct '00

02 Oct '00

Hi everyone, I'm running Zope 2.2.2 on Linux. All of the sudden I've got some DTML methods that are no longer being acquired in subfolders. I changed the HTML a bit and the whole thing stopped working! I've got some little navigation menus that I'd like to reuse in subfolders by simply referring to them via <dtml-var foo> and having them acquired from the parent folder. Anybody know when this is happening? Here's a sample of the code and the traceback: <table width="100%" border=0 cellpadding=1 cellspacing=0 bgcolor="#000000"> <tr> <td width="100%"> <table width="100%" border=0 cellpadding=2 cellspacing=0 bgcolor="#6666FF"> <tr> <td width="100%"> <font face="Verdana, Arial, Helvetica, sans-serif" color="004A6D" size=2> <font color="#EEEEEE">Quick Links</font> </td> </tr> </table> </td> </tr> <tr> <td width="*"> <table width="100%" border=0 cellpadding=2 cellspacing=0 bgcolor="#EFEFEF"> <tr> <td><font face="Verdana, Arial, Helvetica, sans-serif" size="2"> <dtml-var lidisc><a href="/Navigation/">Site map</a><br> <dtml-var lidisc><a href="/distinfo">District Information</a><br> <dtml-var lidisc><a href="/feedback">Site feedback</a><br> <dtml-var lidisc><a href="http://mail.isd197.k12.mn.us/servlet/webacc">E-Mail System</a><br> <dtml-var lidisc><a href="/about">About our site</a><br> <dtml-if "AUTHENTICATED_USER.has_permission('Edit', this())"> <dtml-var lidisc><a href="/web-devel/">Web-devel Page</a> </dtml-if><br> </td> </tr> </table> </td> </tr> </table>  Any ideas? -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.k12.mn.us/ | http://www.zope.org/ W.

Re: [Zope] SQL errors

Or do I have to hack ZODBC to return different errors? You know the "error_value" variable defined inside the "dtml-except"? Maybe, it can give you additional information about the kind of error. If it is the wrong one, reraise the exception. Dieter

Hexcolors and DTML
by Peter Bengtsson 01 Oct '00

01 Oct '00

This might be a math-python question but... All I want to do is to print out the hexvalue of all black/white colors for a "fading HTML table". #ffffff, #fefefe, #fdfdfd, ... #020202, #010101, #000000 I can do a loop from 1 to 255, but I don't know where to go from there. BTW, are there non-websafe greycolors? Can the loop be for only websafe ones?

sendmail tag strangeness
by Scott Burton 01 Oct '00

01 Oct '00

I have searched around about sendmail tag problems on the list and have found similar answers to my question. However none of them work. I have used this syntax <dtml-sendmail mailhost="MailHost"> To: <<dtml-var recipient>> From: <me(a)mydomain.com> Subject: <Whatever> body.... </dtml-sendmail> I pay close attention to not having any whitespace before the To: and From: headers. I receive this error from multiple SMTP hosts: 503 must have sender and recipient first I can send an email with this syntax: <dtml-sendmail mailhost="MailHost" mailto="you(a)yourdomain.com" mailfrom="me(a)mydomain.com"> body... </dtml-sendmail> The problem is, I have to put in the recipient by hand. This method is supposed to email a recipient after filling out a form so the recipient has to be a variable. When I try using <dtml-var recipient> or &dtml-recipient; or _[recipient] I still have errors or the SMTP log shows that the variable does not get evaluated and shows up as a string of <&dtml-recipient;> as being the recipient in the SMTP header. Is this a bug? Is there something else I could try? TIA Scott B.

LocalFS manage_addFolder solution?
by jensebaer 01 Oct '00

01 Oct '00

Hi all, while searching for a solution to add a folder to LocalFS, I found this message: ______________________________________________________________________________ > Folder creation isn't really supported in LocalFS at the moment. Very > low level support is there (module function _save_Folder) but it's not > intended to be called externally and there doesn't seem to be any path > to call it. There is certainly not a local definition of > manage_addFolder in LocalDirectory. This is on my list of stuff to do > for our site, but I don't know if it's on Jonothan's list for the real > product. It is. It's hard. I'm going to need some help with this one, I'm afraid. --jfarr ______________________________________________________________________________ My question: Is there now a solution to perfom manage_addFolder to LocalFS? Thank You Jens

Z class complexities
by Nolan Darilek 01 Oct '00

01 Oct '00

I'm having a kinda complex problem, and hopefully my explanation can do it justice. :) I'm using zope to construct an XML document from the contents of a folder. Basically, the folder's index.xml iterates through the folder's contents, rendering each object to produce the final document. The objects are separate z classes which combine various properties into a small snippet of the larger XML document. The z class has a render() method which combines the properties into the XML snippet. I have a Render view configured to run this method, and it works. (Though for some reason it adds a <html><head>..., which I'd really like to get rid of. How can I?) I've written the index_html to collect the individual objects and concatenate their contents into an XML document. The code for the method is below: <?xml version="1.0"?> <espsetup-list> <dtml-in "PARENTS[0].objectValues('ESPPackage')" sort=title> <dtml-var "_[_['id']].render()"> </dtml-in> </espsetup-list> This almost gives me what I want (I say "almost" because everything works, short of the render() call.)

Thanks a bunch in advance.
