You can change the command line of z2.py in the registry. I am not yet up to speed on the use of the command line for ZServer.py, but I believe it'll let you use its commands to do it that way. Read the doc string in ZServer/ZService.py for more information. -- Martijn Pieters, Web Developer | Antraciet http://www.antraciet.nl | Tel: +31-35-7502100 Fax: +31-35-7502111 | mailto:mj@antraciet.nl http://www.antraciet.nl/~mj | PGP: http://wwwkeys.nl.pgp.net:11371/pks/lookup?op=get&search=0xA8A32149 ------------------------------------------

automated setting of object properties?
by Darran Edmundson 07 Sep '99

07 Sep '99

I wonder if someone could offer advice on how to accomplish the following ... I notice that in version 2.x of Zope, uploaded images autmagically get their height and width properties set appropriately. This was not the case with version 1.x, at least for content import via the fsimport external method. I imported a slew of content with Zope 1.x and thus have a lot of images with height and width properties of 0. I would like to write an external method to scan through my entire database setting the height/width fields to their correct values. So far I haven't had any luck getting this to work. Any advice would be much appreciated. Cheers, Darran. -- Darran Edmundson [Darran.Edmundson(a)anu.edu.au]

If you look at the current user management ui, you'll not that is calls (among other things) manage_addUser. You can reimplement the user management interface that you want using DTML Documents and Methods. Of course, at some point you'll also need to call manage_addUser:  You can give the document that contains this call the Manager proxy role... Hope this helps, --Rob

why does absolute_url now call urllib.quote?
by Anthony Baxter 07 Sep '99

07 Sep '99

Sometime on the way to Zope2, OFS.SimpleItem.Item.absolute_url was changed to call urllib.quote on the string it produces. This will break things that expected the previous behaviour... Just a warning for anyone else who might be bitten by this (it breaks my dataminer... :( (see line marked 'This line.' in the following diff.) - def absolute_url(self): + def absolute_url(self, relative=0): """Return an absolute url to the object. Note that the url will reflect the acquisition path of the object if the object has been acquired.""" obj=self url=[] while hasattr(obj, 'aq_parent') and hasattr(obj.aq_parent, 'id'): - id=callable(obj.id) and obj.id() or obj.id - url.append(id) + id=callable(obj.id) and obj.id() or str(obj.id) + url.append(quote(id)) # << This line. obj=obj.aq_parent - url.append(self.aq_acquire('REQUEST').script) + if not relative: url.append(self.aq_acquire('REQUEST').script) url.reverse() return join(url, '/') -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

Getting PCGI to work with ZServer - how?
by Chris Allen 07 Sep '99

07 Sep '99

Hi, I've just upgraded to Zope2 (using the source dist'n) and I'm trying to work out how to use the PCGI facility of ZServer instead of pcgi_publisher.py with Apache. According to the README.txt for ZServer: To use PCGI, configure your PCGI info files to communicate with ZServer by setting the PCGI_PORT, PCGI_SOCKET_FILE, and PCGI_NAME. The other PCGI settings are currently ignored by ZServer. OK, so I setup the Zope.cgi file: #!/wrk/web/dev/pcgi/pcgi-wrapper PCGI_NAME=Zope PCGI_PORT=8079 PCGI_PID_FILE=/wrk/web/dev/pcgi/var/pid PCGI_SOCKET_FILE=/wrk/web/dev/pcgi/var/socket PCGI_ERROR_LOG=/wrk/web/dev/pcgi/var/log PCGI_DISPLAY_ERRORS=1 INSTANCE_HOME=/wrk/web/dev/Zope Start up Zope and the server is running fine. Then I try to access it via apache and get a "can't locate publisher" error. So I add the following line (assuming its ignored by ZServer): PCGI_PUBLISHER=/wrk/web/dev/pcgi/dummy.py Now all I get is: pcgi-wrapper: Interrupted system call (102) failure during connect All the HOWTO's I could find seem to talk about pcgi_publisher instead of ZServer. I guess I'm probably missing something basic here - any pointers?? Thanks, Chris

Could >someone enlighten me? In Zope, the term "acquisition" is used to refer to objects being "acquired" from higher up in the hierarchy. An object in G can access anything in A directly by object ID, as can something in D. To get to G from B, you would need to do something like this: <dtml-comment>Let's start at the root</dtml-comment> <dtml-with "PARENTS[-1]"> <dtml-with C> <dtml-with G> <dtml-var some_property> </dtml-with> </dtml-with> </dtml-with> Note that you can also do this in many circumstances: <dtml-var "PARENTS[-1].C.G.some_property"> >2.

If you do _['sequence-item'], you will get the value of sequence-item (ie, the object id). If you do, _[_['sequence-item']], it will look that objectid up in the namespace. Kevin

Two newbie questions
by Chris Fassnacht 07 Sep '99

07 Sep '99

Hi, I'm new to Zope but have some programming experience and elementary web-design skills. I've been looking through the list archives, but haven't found the answers to a couple of questions. Hope someone can help. 1. Object reference across hierarchies. If I have a folder structure like this: A / \ B C / \ / \ D E F G Then I can reference an object in A, B, or D from A, B, or D using <dtml-var objectid>. But if I try to reference something in G from B, for instance, I get a Zope error. I'm not fully up to speed on the idea of namespaces, but I get the feeling that this is the source of my problems. Unfortunately, I'm not sure how force a reference to something in a different namespace using only its object id (that is, without having to reproduce the full url path). Could someone enlighten me? 2. Looping a lines property I've been trying to use the <dtml-in> loop structure to go through the entry in an custom ZClass object's lines property. But I'm not sure of the syntax (I've looked through most of the documentation and can't find more than a minimal description on pg. 44 of the Zope Conten Manager's Guide), and what I've tried so far isn't working. I can access individual line items using <dtml-var "objectid.linesid[n]">, but was hoping to avoid having to create an increment variable for n, test, increment, etc., since the <dtml-in> structure looked so slick. What I'm trying to do is to maintain a list of object ids in an object's lines property and then generate links (<a href=>'s) from the list. So, I could also use some direction in using the referenced object id in the lines property to access its properties (title, mostly). Thanks very much for any assistance. Chris Fassnacht

Hello, fellow Zopers - about the CIS..
by Eron 07 Sep '99

07 Sep '99

Greets. I am the developer of the CIS project, and, would like to give a quick notice to all: 1. 1. The CIS project is a project aiming at helping communities everywhere build their own civic networks (there is a report on this at CIS's website). It is very different from anything that might seem to be similar in design. I feel the documentation is coming along well, and a clear understanding of what it is can be gathered from it. Anyone with qustions will be warmly welcomed to contact me (and maybe point out somthing I have missed). 2. 2. The CIS project is NOT competing with Zope in anyway. One of the main things we are interested in is the Portal Toolkit - it seems like a very good design in be incorporated into the CIS. If, somewhere down the road, we are fortunate to extend it's capabilities beyond that existing now, we plan to make the developments available back to the Zope community. Remember, Zope is the CIS's framework, the Portal Toolkit an engine. We are not attempting to replace anything Zope is doing. Zope is good. Zope is great. That's why we chose it, dig? :-) Great, now we are all on the same level. Keep up the good work, guys!! Working for the good of mankind, Eron Lloyd (EarthTone)

That's just how I design - think about what the problem *really* needs, and then figure out how to do a scaled down version of it that's actually implementable within budget. The nice thing about this approach is that it: A) helps prevent you getting stuck further down the road, and B) often gives you a simpler way of doing things, with spin-off benefits you weren't originally looking for. Polya's Paradox states that it's often easier to create a general solution for a class of problems and then to specialize it for your specific problem, than to build a specialized solution just for your one problem. The ZPublisher concept itself is a brilliant application of this principle. >But it WAS a great post and brought up a lot of requirements >and considerations that I hadn't thought about. Well, you probably don't need/want a full-blown scheduling system like what I described, but the basic ideas of an Event, Schedule, and CalendarEntry can probably still help you with your projects. You might even leave out Schedule, since Schedules are only needed to manage resource commitments, and it sounded like that would be external to your application. Anyhow, just focus the ideas much more specifically for your application. Then, if a full-blown system ever shows up, your application is already designed in a way that would make it conceptually straightforward to port over and take advantage of the rest. There is a good chance that I or other members of my team will be tackling some of these items in the not-too-distant future, though I expect it could be quite a while before we have a robust general system. I *do* have some interest in design collaboration by fellow Zopesters, however, and I think it would be great if we could hash out the interface protocol for the different pieces and then all begin making components that work according to that API. Maybe Zope needs some SIG's along the lines of the various Python SIG's... Hmmm. :)
