linuxworld article and auto-form generation
by Kapil Thangavelu 16 Jul '00

16 Jul '00

I played around with some auto-form generating ZClasses a couple months ago. Just thought i should share since it seems to be something people want, and i saw it used as a feature-lack against zope on linuxworld. basically it just spits out an html page where you pick a property sheet and then it spits up an edit form for that sheet. i use em for quick testing of a zclass and as a template(ala view source) for more customized forms. i generally use it a base zclass on a project and just make my other zclasses inherit from it. to view the forms after you've created the methods (in your the Products folder of your ZClass) just go to http://YourZopeSite.zope/YouObject/edit_properties this stuff will be on my members page, soon:) http://www.zope.org/Members/k_vertigo standard_disclaimer -ie it works for me. use at your own risk. raw dtml - sorry i'm sure the formatting blows edit_properties :: dtml_method <dtml-var standard_html_header> <center><b>Please Pick A Property Category</b></center> <table align="center"> <form action="edit_propertyCategory" method="POST"> <tr><td> <SELECT name="PropertyCategory"> <dtml-in "propertysheets.items()"> <OPTION value="<dtml-var sequence-key>"><dtml-var sequence-key></OPTION> </dtml-in> </SELECT> </tr></td> <tr><td><INPUT TYPE="SUBMIT" value="Edit Properties"></td></tr> </form> </table> <dtml-var standard_html_footer> edit_propertyCategory :: dtml_method <dtml-var standard_html_header> <dtml-if "REQUEST.has_key('PropertyCategory')"> <dtml-in "propertysheets.items()"> <dtml-let y=sequence-key> <dtml-if "REQUEST.PropertyCategory==y"> <dtml-let x=sequence-item> <table border="1" align="center" cellspacing="0" cellpadding="4"> <tr><th colspan="2" align="center">Edit <dtml-var y> Properties</th></tr> <form action="edit_propertiesChange" method="POST"> <dtml-in "x.propertyItems()"> <tr><td> <dtml-var sequence-key> </td><td> <input type="text" name="<dtml-var sequence-key>" value="<dtml-var sequence-item>"> </td></tr> </dtml-in> <tr><td colspan="2" align="center"><input type="SUBMIT" value="Change Properties"></td></tr> <input type=hidden name="PropertyCategory" value="<dtml-var PropertyCategory>"> </form> </table> </dtml-let> </dtml-if> </dtml-let> </dtml-in> <dtml-else> You have reached this page in error </dtml-if> <dtml-var standard_html_footer> edit_propertiesChange :: dtml_method <dtml-var standard_html_header> <dtml-if "REQUEST.has_key('PropertyCategory')"> <dtml-in "propertysheets.items()"> <dtml-let y=sequence-key> <dtml-if "REQUEST.PropertyCategory==y"> <dtml-let x=sequence-item> <dtml-call "x.manage_changeProperties(REQUEST)"> <dtml-var PropertyCategory> Properties Changed<br> <a href="<dtml-var URL1>">Back To Object</a><br> <a href="<dtml-var URL2>">Back To Container</a> </dtml-let> </dtml-if> </dtml-let> </dtml-in> <dtml-else> You have reached this page in error </dtml-if> <dtml-var standard_html_footer> Cheers Kapil http://lostworld.imeme.net

PIL on Win32 for the Photo Product
by Alexander Limi 16 Jul '00

16 Jul '00

Hi, I need PIL in my Zope install to get the Photo product working. I downloaded the win32 version of PIL from http://starship.python.net/crew/da/PIL/ and tried unpacking it in the bin\python dir of my Zope install. Photo reports the following: Traceback (innermost last): File "C:\PROGRA~1\Zope\lib\python\OFS\Application.py", line 387, in import_products product=__import__(pname, global_dict, global_dict, silly) File "C:\Program Files\Zope\lib\python\Products\Photo\__init__.py", line 42, in ? import Photo File "C:\Program Files\Zope\lib\python\Products\Photo\Photo.py", line 87, in ? from PIL.Image import BICUBIC, BILINEAR, NEAREST ImportError: No module named PIL.Image The web pages say something about a pil.pth file, I can't find that anywhere in the archive either. Can anybody give me some hints on what to do? Alexander.

DTML Problem (from the newbie "hair ripper" category)
by Darin Lee 16 Jul '00

16 Jul '00

Greetings, I have created a custom Zclass called "Category." This object is based on the "objectManager" template. Essentially this object is a container with a few properties attached; "navigation_name" and "description." Essentially, the gist of this is to create a navigation menu with a <dtml-in> loop that displays all of the Category('s) in a given directory. However, I want the property "navigation_name" to show up as the hyperlink text. Does this make sense? So, if I simply call the <dtml-in "objectValues(['Category'])"> and then print the name with <dtml-var navigation_name>, everything works fine!! Here is the proverbial rub. If I want to *test* for the presence of "navigation_name" so I can print "title_or_id" if it's not defined, Zope simply skips the "navigation_name" property. It's like it always evaluates to false! Example for "left navigation" dtml method: <dtml-in "objectValues(['Category'])"> <dtml-if "hasProperty('navigation_name')"> <dtml-var navigation_name> <dtml-else> <dtml-var title_or_id> </dtml-if> </dtml-in> Okay, I think to myself "self, maybe acquisition is getting in the way," so I try: <dtml-in "objectValues(['Category'])"> <dtml-with sequence-item> <dtml-if "hasProperty('navigation_name')"> <dtml-var navigation_name> <dtml-else> <dtml-var title_or_id> </dtml-if> </dtml-with> </dtml-in> Doesn't work! Could this have something to do with the definition of my own Zclass? Do I have to read into the property sheet specifically? Is there a command for that? I took the example from the excellent "Breadcrumb Navigation Trail Howto" and that works fine, as long as I use a supplied Zope object (like "folder"). As soon as I use my own ZClasses, this breaks. (I'd like to get my "navigation_name" into the breadcrumbs as well. Thanks in advance, -Darin Lee

It seems they forgot to compile the PCGI wrapper... here is what you should do to make it work: ---------------------- cd pcgi sh ./configure make --------------------- Worked fine for me.

Starting Zope v2.2.0 with daemontools etc. - problem starting!
by Jørgen Skogstad 16 Jul '00

16 Jul '00

Hi there.. I've just tried to install the new Zope with daemontools .. but I seem to get an error after I initiate zope through dameontools with "svc -u /service/zope" .. here what it continues to output; 16:52 zope@nexus [ /usr/local/zope/Zope-2.2.0-solaris-2.6-sparc > more temp.txt Traceback (innermost last): File "/usr/local/zope/Zope-2.2.0-solaris-2.6-sparc/z2.py", line 289, in ? here=os.path.join(os.getcwd(), os.path.split(program)[0]) OSError: [Errno 13] Permission denied 16:52 zope@nexus [ /usr/local/zope/Zope-2.2.0-solaris-2.6-sparc > .. zope is suposed to run as uid zope .. and gid zope .. and therefore I start it in the run script with "setuidgid zope" .. and I've tested the run script alone = it works! .. though when starting under daemontools it complains about the above. stuff.. .. anyone seen this .. or know why? .. need input from you other zopeaistas!

FW: [Zope] linuxworld article
by George Donnelly 16 Jul '00

16 Jul '00

this is a smear and a cowardly one. one small complaint about the default dtml methods produced when creating a zclass does not an intelligent criticism make! zope is not perfect but he failed to describe any serious problems. imo Regards, GEORGE DONNELLY george(a)cyklotron.com http://cyklotron.com/ The truly and deliberately evil men are a very small minority; it is the appeaser who unleashes them on mankind; it is the appeaser`s intellectual abdication that invites them to take over. --Ayn Rand > http://www.linuxworld.com/linuxworld/lw-2000-07/lw-07-penguin_2.html > > Hmm...what is your opinion on the article above? I'm interested to see the > author's comparison btwn Enhydra and Zope. > > regards, > firestar
