However, you can use the REQUEST object as a variable container. If your problem is to collect all recipients from the form and feed them to "sendmail" you could do something like this: <dtml-call "REQUEST.set(recipients,[])"> <dtml-in "REQUEST.form.items()"> ... <dtml-call "recipients.append(_['sequence-item'])"> ... </dtml-in> <dtml-sendmail ...> To: <dtml-var "_.string.join(recipients,', ')> .... </dtml-sendmail> You can even let ZPublisher form the list for you: give all form variables that will contain a recipient the name "recipients:list:ignore_empty" Then, if at least one of these fields got a value, you REQUEST will have a variable "recipients" containing a list with all these fields. I would like to point you to Python's "in" operator. Instead of _['sequence-key'] == 'message') or or (_['sequence-key'] == 'sender') or (_['sequence-key'] == 'senderEmail') or (_['sequence-key'] == 'subject') you can write: _['sequence-key'] in ('message','sender','senderEmail','subject') Easier to write and to read.

RE: [Zope] Zope and Linux flavors

Perhaps another option (for those with a load-balanced server setup), use an intel 7170 (not cheap, but cool) load-balaning appliance, and use the loadbalancer as a router; the 7170 has the abilitiy to set rules for where it sends the load to based upon expression-matching in the URL. This means that you could intercept all "/manage*" URLs with the load balancer and direct them to a box that returns nothing but error pages. I haven't done this (I have a 7140, this model's lower-end sibling), but I have looked extensively at the docs for this, and it might be an option for the cash inclined. Other than that, this doesn't get you out of securing your boxes. I would recomend traditional security strategies (putting servers proxied behind a DMZ), and a box-by-box audit of services using a port scanner. Other than that, I can recommend one of two realistic strategies in dealing with Linux (I dont' claim to be a security expert though) - either: build the distro yourself (i.e. LFS, www.linuxfromscratch.org) and keep tabs on what services are running, as well as monitoring the lwn (www.lwn.net) security page every week, or... Commit to a particular distribution/vendor and get on their security mailing list post-haste. Apply all patches before putting the box out on the net at large. And keep the box patched. Also, monitoring lwn's security page or bugtaq isn't such a bad idea. If you have the time to invest in it, consider a network intrusion-detection system and tripwire to watch the filesystem changes on your boxes.

We run a variety of RedHat 6.1, 6.2, and 7.0 and Debian 2.2, as well as Solaris. We apply all the latest updates, turn off services we don't use, and proxy Zope through Apache. We then block all but port 80 at the router. The servers are then firewalled off from the rest of the network. Simon -- --------- My opinions are my own, NIP's opinions are theirs ---------- Simon J.

Re: [Zope] commit_sub error in Product

This is a bug, that has been reported several times recently. Your file is probably quite large and Zope wants to store it piecewise in the ZODB (in several subtransaction). However, some necessary object does not have the "commit_sub" method. Look into the collector, whether the bug is already recorded. If not, do it. Dieter

Of cause, the approach above will not change this spelling (at least I hope so; one never knows with MS tools). Tell you boss, it is a feature and that references to related documents are distinguished by the capitalization convention (as it is, really). Dieter

What you want is: <dtml-call expr="REQUEST['sqlSearchcust3']"> This does nothing (maybe raises a KeyError 'sqlSearchcust3'), as "dtml-call" evaluates for side effects only and does not produce any text. "REQUEST['sqlSearchcust3']" does not have side effects. Now, "<dtml-in sqlSearchcust3>...</dtml-in>" may also do nothing. Though, this is usually not expected. I suggest, you read carefully the DTML chapter in the upcoming Zope book and try to understand the semantics of the various DTML tags. Dieter

<dtml-var expr="maand" missing=1>???
by Edwin Martin 16 Jan '01

16 Jan '01

Hello, How can I use an undefined variable in an expression? I made a DTML document which gets parameters from the URL, like "/nieuw?maand=1". But I also want it to work when no parameters are given. 'Missing' should be the answer, but the following doesn't work: <dtml-var expr="_.int(maand)+1" missing=1> <dtml-let defmaand=maand missing=1>...</dtml-let> <dtml-in listbydate reverse size=20 start=maand missing=1> I expected to find a solution in http://www.zope.org/Members/michel/ZB/DTML.html http://www.zope.org/Members/michel/ZB/AppendixA.html but couldn't find it.

When they are (and will be) only used by your ZInstances, put them there. When they are of more general interest, put them somewhere, where can are found by all interested parties. Dieter

change parameter by mouseclick

Hi everybody, Right now we use the following statement to change the language on every page the user is. very neat made by the NFGnav guys. <a href=<dtml-var URL0?ll=de>><font color=yellow>German</font></a> unfortuanately if the user is on a page with an url like this http://sino:8080/ipOperate/reports/fac_base_report.htm?fac_id_only=&mod_id_… yes, i'm proud on that one :-) the statement doesn't work anymore :-) because it doesn't simply change the "ll" variable to "de" but also kills quite some other needed variables (all, actually) i assume the solution goes with this one, but how can i activate in a menu without fucking up my lovely url? <dtml-call "REQUEST.set('ll','de') thanks for help -- and you guys are great help :-) hope to give back some know how after this project slows a bit down olaf -- soli-con Engineering Zanger Dipl.-Ing.
