Creating Member folders with the Membership Product
by tav 08 Oct '00

08 Oct '00

Hi, I have been trying to mimic the way the PTK (and zope.org) automatically creates a Member folder with specific objects, when someone signs up. I want to do something similar, but call it something other than Members/ and have 5 objects in a subfolder copied over to the User's directory that is created. Currently I am using the PTK, but am also interested in Bill's Membership Product. So, if anyone could guide me as to how I can achieve this with either, I would be very grateful. -- best regards, tav tav(a)espnow.com

It will work, when you use: <dtml-with "Bill">...</dtml-with> Note the "...". They prevent automatic rendering. > and, again, i want this to be done automatically, so i dont want to have to > manually list Bill, tav, noa, etc.... This is an FAQ. You want computed variable access. You use "_.getitem(...)" (if you want the object itself) or "_[...]" (if you want a rendered result) for this. Thus, if you want to process all owners, you could do: <dtml-in owners> <dtml-let owner=sequence-item> <dtml-with "_.getitem(owner)"> <dtml-var parseit> </dtml-with> </dtml-let> </dtml-in> Dieter

Can you specify user/group to run Zope as during install
by Yusuf Goolamabbas 08 Oct '00

08 Oct '00

I would like to run Zope not as user 'nobody' but as something else. Is this possible somehow, also is it possible to install the Zope tree in a location other than that untarred into [something like ./configure --prefix=/usr/local/site/Zope] Regards, Yusuf -- Yusuf Goolamabbas yusufg(a)outblaze.com

AUTHENTICATED_USER (or something) making me crazy
by Dennis Nichols 07 Oct '00

07 Oct '00

If I inspect REQUEST by inserting a <dtml-var REQUEST> in my dtml I can see that AUTHENTICATED_USER is set to Anonymous User. Yet when I insert the following code, it never displays Guest. It takes the else branch and then, perversely, displays Anonymous User. Please point out my stupid mistake. <dtml-if "AUTHENTICATED_USER=='Anonymous User'"> Guest <dtml-else> <dtml-var AUTHENTICATED_USER> </dtml-if> Thanks. Maybe I shouldn't work on Saturdays.

This is despite the fact that I'm now stuck sending plaintext to everyone in our organization! My suspicion is that some well meaning but deranged Exchange SMTP gateway server is doing the conversion, as there's a meta tag that says the HTML generator is Exchange. I've tried talking to the people who run the servers, but they are clueless and keep saying it's something I'm doing. So I just try to avoid posting to the list from Outlook, but last night at the office I was (and still am) desparate. But now I'm home with Linux/Mutt. Yay! :-) </RANT> Sorry you had to read that.

HTML-Code in variables (addition)
by Lars Heber 07 Oct '00

07 Oct '00

Sorry, I mixed something up. Normal html is no problem at all. The problem is how to use quotes or such things. Of course I get an error by typing: <dtml-let text="my html text with a link to <a href="http://www.yahoo.com">Yahoo!</a>"> I tried typing " instead of ", but then the """ also goes into the html code on my page - thus the link is broken... Are there any possibilities to let Zope change the " into ", or perhaps there is another way to do it like with the \" in C. Thanks to you all! Lars

WHY ? WHERE DO I HAVE TO > DEFINE THAT ? > when i type in "superuser" and the password for the superuser I DO HAVE > access to the dtml-method "mymethod_html". When I try this in my (installed) Zope 2.2.2, I get a name error both as manager and superuser. Obviously, the ZClass methods are no longer directly accessable via the ZClass. I suppose, ZClass methods are not supposed to be used independent from ZClass instances. When I access the method via a ZClass instance, everything works as expected, i.e. it can be used both by manager and superuser (and probably others, I just did not try). Dieter

"Knight" once said: > > cw, > > Are you spawning additional threads by chance? Or just the threads that > Zope creates? No, I'm a Python newbie who doesn't know of threads yet, so this is just Zope threads working their magic. :-) Right now I'm just shooting for a simple network client as a proof of concept, though ultimately I need to take into account that the server this client is talking to is *cough* single instance and single threaded (i.e. only one client at a time). So what I really need to do for the long haul is set my client software up to hold a persistent connection and multiplex/queue the requests. I assume that means I'll need to rewrite my External Method interface as a Zope Product? Maybe I should try to grok one of the database connection products and model after that? The server is Rand McNally's Unix Resident MileMaker (URMM) milage calculation software for shipping, if you were wondering (what to avoid?)

Zope, Threads and Signals
by Wilkinson Charlie E 07 Oct '00

07 Oct '00

It all began when I was a small child, but I'll skip ahead a bit.... Last night I wrote a network client class with plans to use it as an External Method in Zope. Works great from the command line. My first real Python program. Mom and Dad were so proud! However, when I plugged it into Zope and tried to call it from a document method, I got this: Error Type: ValueError Error Value: signal only works in main thread Gack!! Um... Silly me, but I wrote all this code to use sigalarm and blocking I/O. Anyone know how I can overcome this great adversity, aside from rewriting it all to use non-blocking I/O? Know of any good examples of External Method network clients you could point me at? Or would making it a Zope Product somehow fix everything?
