Plone Macro Madness
by D. Bickle 12 Mar '04

12 Mar '04

Hi All, I am using Plone to provide the look and feel for my application. When I embed the page macros in a html file Zope renders the macros wonderfully. However when I use a Python script to generate html using print statements it doesn't appear to be working. The code looks something like this: print '<html metal:use-macro="here/dialup_template/macros/dialup"></html>' Then some more dynamic HTML in Python.... print '<div class="footer" metal:use-macro="here/footer/macros/portal_footer">Footer</div>' return printed Any suggestions? Thanks in advance.

problem calling a Python external method in a folder from a DTML method
by Jim Anderson 12 Mar '04

12 Mar '04

I've had a few questions on DTML in the past week. This should be my last DTML question for a while for serveral reasones: 1) If I can make this last example work, I'm pretty sure that I can do all that I want or need to do in DTML. Actually, I want to do very little in DTML and quite a bit in Python so I don't think I need too much DTML capability. 2) My experiment DTML application will be working once the issue below is resolved. 3) I plan to take the nudging toward ZPT and start an experiment application in ZPT. Hopefully, I will then be done with DTML. Thanks to Troy Farrell, Chris Withers, and Jonathan I have a problem using Zope 2.7.0. I've tried Zope on both a Linux and Windows PC and have the same problem. I'm working on a DTML method in which I want to call an external method in a folder, 'F'. F is a subdirectory of the directory in which the DTML resides. The method, 'M', is in an external module 'M.py', so the path from the current folder is 'F/M'. My folder has a property, "Sample", with a value of "Sample Text". The method, M, returns a string value, "M method". First I try calling F.M() <p>Calling a method</p> <dtml_var expr="F.M()"> <p>After method call</p> Then I try using the dtml-with tag using F as the object being pushed on the stack. <dtml-with F only> <h2>Sample: <dtml-var sample></h2> <p>Calling a method</p> <dtml_var expr="M()"> <p>After method call</p> </dtml-with> When this DTML method is run, the output looks like: Calling a method After method call Sample: Sample Text Calling a method After method call The sample property renders properly, but not the method output. The output does not include the string returned by method, 'M'. I've experimented with a number of different possibilities, but I can not get method 'M' to run. But I get no error messages either. I've tried wrapping the calls to 'M' in a dtml-try statement, but no exception was raised. When I test my M.py file in the Extension directory, the python file executes as expected. Can anyone give me a suggestion on how to get this method to execute from the DTML when a dtml-call or dtml-var tag is used? Jim Anderson

Using ObjectManager class
by Serg 12 Mar '04

12 Mar '04

<file min_all.py> .... class min_all(SimpleItem.SimpleItem,ObjectManager): ... manage_options=(ObjectManager.manage_options + ({'label':'Edit Minimal', 'action':'manage_editMin_allForm'}, )) ...... def addFoo(self,id,dn): "add Foo object to min_all object" O=Foo(id,dn) self._setObject(id, O) self._p_changed=1 def delFoo(self,id): "del Foo object from min_all object" O=Foo(id,dn) self._delObject(id) self._p_changed=1 Function delFoo and addFoo working normally. For example, I can't add second Foo object with existing id, and I can't del Foo object with not existing id. But I can't see objects on ObjectManager.manage_options tab! I see only message: "There are currently no items in min_all1". I think, that problem is in _getOb function of ObjectManager class.... How can I change this function? And where can I read information about using ObjectManager class? Regards, Serg.

Problems installing Archetypes
by Nitin Mistry 12 Mar '04

12 Mar '04

Hello, I am a new person looking into Zope. I downloaded the latest versions of Zope & various products in the last two weeks. I am having problems installing the Archetypes Product. It comes with two packages called generator & validation which need to be installed using "python setup.py install" which puts the built files into <Zope>/bin/lib/site-packages However zope cannot find the "generator" module on startup. I have tried to put the same package into lots of other locations like lib/python, lib/python/product, bin, ... BUT all to no success. Could someone help me install this product? Environment: Windows NT service pack6a Zope 2.7.0 Latest Versions of many products - tried Archetypes 1.3.0 & 1.2.4 - generator is version 1.0.1 Thanks Nitin Mistry

by Peter Millar 11 Mar '04

11 Mar '04

I have found in my zope\bin directory a runzope.bat .this is great it works well. The only way I get the app server to stop is by doing CTRL-C. Ouch . there has got to be a nicer way . and please don't say use zopectl . from what I can gather it only works on unix or if you want me to use this in windows what are the commands?? ____________________________________________ Peter Millar Technical Project Manager Parasyn Controls Pty Ltd Peter.Millar(a)Parasyn.com.au T: 61 7 3396 6388 F: 61 7 3396 6299 45 Millenium Place, Tingalpa QLD 4173 PO Box 400 Cannon Hill QLD 4170 Australia www.parasyn.com.au <http://www.parasyn.com.au/>

finding orphaned Product objects
by Fred Yankowski 11 Mar '04

11 Mar '04

I want to clean up a Zope instance to remove some installed products that are no longer needed or even available in the filesystem any more. I've got an idea about how to do that and I'm looking for feedback about any problems or shortcomings. My first thought was to look at each Product object under Control_Panel.Products and check to see if its home directory exists. Those objects do have a 'home' attribute but it seems to be unreliable; the values often refer to directories that no longer exist (but did exist at the time the product was installed). Such incorrect home values sometimes occur for products that do exist under $INSTANCE_HOME/Products and that I'm still using. I wasn't able to find any other per-Product attribute with such home-directory information. No joy there. What I've got now (see attached script) considers each of the Products and tries to find an imported Product module by the same name. Any Products without such a module are either orphans (my term) or are a product created strictly through the web using ZClasses and the like. I think. I'm planning to delete the orphaned products from the Control_Panel/Products folder in the ZMI. Does this plan make sense? -- Fred Yankowski fred(a)ontosys.com tel: +1.630.879.1312 OntoSys, Inc PGP keyID: 7B449345 fax: +1.630.879.1370 www.ontosys.com 38W242 Deerpath Rd, Batavia, IL 60510-9461, USA

[ANN] mxmDynamicPage 2.0, Plone content type for dynamic lists released
by Max M 11 Mar '04

11 Mar '04

The mxm Dynamic Page product for Plone makes it easy for end-users to make dynamic pages that aggregates lists of content from a part of a Plone site. In short, it makes it easy to add dynamic lists to a document. It is especially usefull as an "index_html" in a member folder, where the member then has the option to make dynamic lists of his content. But it can also be used to make custom versions of the common "news" page, or pages similar to that. It does nothing that Topics and ZPT cannot do, but that approach is far to difficult for end users. I also found the current products that creates dynamic pages too complex and difficult for end users. I have tried to find the sweet spot between power and ease of use. Previous versions has been used in production for allmost a year, with good end-user satisfaction.

by Florian Schulze 11 Mar '04

11 Mar '04

Hi! I would like to know wether there is a way to test if a macro evaluates to nothing. I tried the following: <div tal:condition="here/my_macros/macros/macro_name" metal:use-macro="here/my_macros/macros/macro_name"> </div> But the macro returns a tree of lists and tuples. Regards, Florian Schulze
