'selection' types question
by Brown, Brian 23 Sep '99

23 Sep '99

I was trying to figure out how to use the types 'selection' and 'multiple selection' and found the following: In <zope dir>/lib/python/ZClasses/Property.py, the following code shows that these type should result in an HTML Select box, if t=='selection': return ('''  <select name="%(id)s">  <option  SELECTED ></option>  </select>  No value for %(id)s ''' % p ) return '' ...but I couldn't figure out how to get any data in it. Then I found in <zope dir>/lib/python/OFS/PropertySheets.py: if type in ('selection', 'multiple selection'): if not value: raise 'Bad Request', ( 'The value given for a new selection property ' 'must be a variable name<p>') prop['select_variable']=value if type=='selection': value=None else: value=[] setattr(self, id, value) This told me that I should be putting a variable name for the value, and that worked fine. The problem them comes with 'multiple select' boxes. Nothing displays, and I think that is due to there being no analog for the first code snippet above. Can someone with more Zope Zen than I confirm this? I think it's a bug, and if so I'll put it in the Collector. btw, this is released Zope 2.0.0 on linux, source release. Thanks! Brian

You can do a whole lot without using Python. For someone who knows how to use a programming language, picking up python is probably not going to be too difficult. >> 2.

If you can do CGI >on your ISP, you can do PCGI with Zope. [some snippage above] One caveat: I have found that many hosting companies are not keen on the PCGI way of doing things, because it permanently sucks up memory, etc. In looking at hosting companies, I found that to be a bigger issue than running Python. (I thought most hosting companies provided Python already). Still, I think Zope is powerful enough to easily justify a switch in hosting companies (which is not really *that* big a deal for many configurations). In fact, I *did* switch hosting companies so that I could use Zope. Kevin

>From my experience of trying to intrest co-workers in Zope there were 2 problems. 1. Python - they don't know python, but might be willing to learn if it wasn't for 2... 2. ISP/Web Hosting companies don't sopport Pyhton as a cgi enviroment or Zope. Very few, from my experience, want to switch ISP/Web Hosting for something they have not tried in a new language. Don't take these comments to mean that I don't like Zope I love it but can't justify going with an untrusted ISP/Web Host. I don't know the solution to this one. Any help would be appreciated. Maybe what effect adding Zope, along with Apache, would have for the ISP/Web Host. Technicaly do they have anything to worry about or is they general lack of python experience the only factor. Any ideas??? ===== ------------------------------------ Brian M Lauer <mailto:fozbaca@yahoo.com> <http://w3.one.net/~fozbaca/> <ftp://ftp.one.net/pub/users/fozbaca/> __________________________________________________ Do You Yahoo!?

RE: [Zope-dev] Barriers to Zope popularity: Part 1: wysiwig editi ng

I think the *approach* of the current Zope management environment has a lot of things going for it: o All functionality is controlled by the server o Not just that, but the management is controlled by *individual* applications (e.g. Indigo Networks uses Flash to control Zope) o You can sit down anywhere in the world and log into Zope o The management screen is "programmed" in a clear-text definition With that said, I know there are some _severe_ drawbacks: o It is an unproductive environment o The TEXTAREA is awful for real editing o No convenient way to get local data to remote server There have been some proposals, namely (a) integrating with some specific tool like FrontPage or Dreamweaver, or (b) creating our own management environment. Both of these are bad ideas for one simple reason: the best tool is _your_ tool, meaning you'll never make a majority of people happy. To date our approach has been to support the standards (namely: FTP, WebDAV, Netscape Publishing, converting to an HTML-like syntax) that makes integration with _all_ tools more feasible. I'm increasingly convinced this will only work at a minimal level: none of them can expect to capture a sufficient amount of the dynamic capabilities of Zope. There's just an impedance mismatch. Thus, I'm drawn back to keeping the advantages of the current approach while trying to address some of the productivity losses. So, here's my suggestion, and I consider it a challenge to the Zope community at large to do a prototype. I've tinkered enough over the last two months to realize it is feasible, I'm just not smart enough to make much progress. Imagine a management environment that: o Kept everything good about the current Zope "IDE" o Was cross-platform o Completely controlled by the server, or optionally controlled locally o 100% compliance for advanced standards such as: - XML, CSS2, XSL, RDF, latest JavaScript, etc. o Contained an embeddable, scriptable editing widget with both plaintext and wysiwyg modes o Had an XML-based UI language containing platform-native tree widgets, tabbed dialogs, pop-up modal dialogs, object-defined menus, right-click menus, etc. o Facility for trusted-scripts to access local filesystem Given this "platform", a management environment could be constructed with some of the following improvements: o A real, HTML-oriented editing box, perhaps with some DTML-aware "smarts" o A collapsible/expandible view of the object system that _didn't_ go to the server on each click o etc. I'm talking, of course, about Mozilla. I've been following it very closely for the last few months, downloading the daily builds probably three times a week on average. It's legit, it has a LOT of energy behind it, and most of all, it's the best shot to keep the strengths of the current approach while significantly improving the productivity. In fact, the same tool, with two different modes/views, can appeal to both the content manager and the developer. My challenge: go tinker with some prototypes. Write some XUL files that populate a tree widget with an RDF source retrieved from a DTML method. Create a real tabbed right-frame using the tabbed dialog. Create alternatives to manage_menu and manage_main that send back XML and CSS2 to cut the http response size in half and significantly improve the layout. For a small glimpse of what you can do with Mozilla: http://204.107.76.15/pub/ --Paul

I believe, possibly on the old site, that there is a Zope produce that lets you plug bobo apps directly into the Zope space with no modification. http://www.zope.org:8080/Download/Contrib/ExternalObjects.tar.gz I think this is it.

Running ZServer on Port 80 as root Permission Denied
by Jason Spisak 23 Sep '99

23 Sep '99

Zopists, I am trying to run ZServer on port 80 so that www.mydomain.com come right out of Zope. I read the docs on z2.py and startingthe http server, ftp server and monitor server look fine. But when it gets to the Z2.pid file I get a permission denied even with a chmod 777 on the entire Zope top directory. I've tried installing as root, as well an unprivliaged user and I get this same error when running z2.py -w 80 in line 494: IOError [Errno 13] Permission Denied '/home/Zope/var/Z2.pid' Help? -- Jason Spisak webmaster(a)hiretechs.com

hi, i was wondering if someone has had this problem as well: i'm trying to create an sql method with a variable argument list i.e. i don't know what arguments need to be passed because i'll be calling this sql method from a dynamically created html form. i was trying to simply pass "REQUEST" as a single argument to this sql method and reference my variables with  or something but that did not work. is there a way to accomplish this? cheers thilo -- mezger(a)innominate.de innominate AG networking people fon: +49.30.308806-11 fax: -77 web: http://innominate.de pgp: /pgp/tm

"upgrading" from ZPublisher to full Zope and need enlightenment
by Michael Olivier 23 Sep '99

23 Sep '99

We've been using ZPublisher and PCGI since the Bobo days for development, and I find myself playing with the zope.org site and finally understanding more clearly what else Zope has to offer. The question now is: what is the path for us to start using Zope beyond ZPublisher. We have a single entry point for our app, which is PCGI-based. Many of the functions inside classes use DTML substitution, though we're doing it from the python side. It's not clear to me how this fits with the web-managed Zope side of things. Is there a doc describing this conversion/upgrade, or are there people who can explain this to me? Maybe someone who's already been through this? Kudos for the greatly improved documentation on the Zope web site! Between the tips, HOWTO's, and being able to play w/it myself in an environment with some pre-existing content, it really helped things to gel. thanks, --Michael
