ZCatalog problems - maybe
by James Sintz 02 May '02

02 May '02

I have recently upgraded to 2.5.1 and the following doesn't seem to ever evaluate as true any more. It has worked in several different versions of Zope with the last one being 2.4.3. When I upgraded to 2.5.0 and discovered this would never evaluate as true I re-index all the items in my catalog. <dtml-let now="ZopeTime().strftime('%Y/%m/%d') + ' 00:00'" a="Catalog( { 'meta_type' : 'news', 'news_goLiveDate' : [ _.DateTime(now), _.DateTime(now)], 'goLiveDate_usage' : 'range:min:max' } )" <dtml-if a> some code </dtml-if> </dtml-let> Any ideas why it would have stopped working. I have made no other changes except the upgrade. I tried importing my files and re-indexing and moving the data.fs. Thanks Jamey

Problems adding attribute to custom object
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 02 May '02

02 May '02

Hello, I'm trying to add a new attribute to all objects of a certain meta_type on my site. These are objects that already exist and are already instantiated. But, no matter how I go about it, I always end up with the same end result: Error Type: TypeError Error Value: attribute-less object (assign or del) I've treid using portal_catalog search results, and then something like : setattr(a,'newporperty',''), but that gives me the error above. I also tried o.property = '', but that didn't help ... I also tried creating myobject = o.getObject() ... no go ... Then I found some examples on various web sites that use ZopeFind to locate their objects ... tried that, still no luck. What am I missing here? One thing, this is a custom object I added to the CMFDefault product, could that be part of the problem? This object otherwise works great within Zope and the CMF. The traceback output varies depending on how I try to go about it, but here is the lastest one: File Script (Python), line 14, in addPropertyToObjectType (Object: english) File /usr/local/Zope-2.5.0/lib/python/RestrictedPython/Guards.py, line 107, in guarded_setattr (Object: density) File /usr/local/Zope-2.5.0/lib/python/RestrictedPython/Guards.py, line 72, in handler "English" is a Portal Folder, "density" is one of my custom objects .... Help ? Thanks in advance, J.F.

Trouble Creating Instance of Custom Product Programmatically
by Dan Shafer 02 May '02

02 May '02

I thought I had understood the instructions at Zope.org but I'm doing something wrong. I have a custom Zope Product called PI_Clearing. It has several ZClasses in it, including one called Clearing. I want to set up a Web fom with which the user creates a new instance of a Clearing object. Following what I understand of the directions, I have this DTML method called startClearing: dtml-call "REQUEST.set('id', 'New Clearing') dtml-with "manage_addProduct['Clearing']" dtml-call "Clearing_add" /dtml-with (Angle brackets removed.) But nothing ever gets created. Clearing_add is the default add method created when I defined the Product and the Class. I've tried adding a dtml-call to set the ID of the object before calling the Clearing_add process. No luck. I get no error messages or anything, just no results. What am I not understanding?

zope as ftp-server
by mich wyser 02 May '02

02 May '02

Hi Zopatistas As i want to manage anything with zope, I also want to use Zope as pure ftp- server. The idea is to let admins manage users/closed groups by the ZMI and a to give a simple public interface over the ftp-file-structure for the end user My idea was to take LocalFs or ExtFile and store the Files externally on the File System. Now i see some Problems/Questions 1. Is there any Possibility to turn off ObjeAct-Acquisiton ? 2. How can i do Logging / Quotas 3. Stability of ftp-server in Zope thanks for any hints and experience in ftp-serving with zope mich(a)maschin.ch

boolean weirdness
by vsbabu＠vsbabu.org 02 May '02

02 May '02

Hi, We've a ZClass in which there is a property fund_size called boolean. We had to use a radio group in the form like fund_size:boolean and values as 1 and 0 for true and false. However, when we had to retrieve it for pre-checking the radio group according to the value in the property sheet, after some trial and error we found that <dtml-if "fund_size=='1'"> works instead of <dtml-if fund_size> as would've expected due to "boolean" property. Took some time to get to the string comparison... $.02

adding class instance
by John Hunter 02 May '02

02 May '02

[This is related to a question I posted earlier but have been unable to solve it. I am reposting with more accurate and detailed information] In the Zope management interface, I have created a Product NewProduct which contains a ZClass NewClass. I have installed and instance of NewProduct at http::/myhost.com:8080/summer/jdh/newtest If I visit http::/myhost.com:8080/summer/jdh/newtest/manage with Manager privileges for the newtest folder, I can add New Class instances to that folder. All is well. I would like, however, to have a file http::/myhost.com:8080/summer/jdh/newtest/index_html where the manager could add New Class instances without entering the manager interface, with something like: <a href="Control_Panel/Products/NewProduct/NewClass_addForm"> add a new class </a> But this gives me get an unauthorized access error because zope is trying to create the class instance in the Control_Panel/Products/NewProduct/ folder which the newtest manager does not have access to. If I use the link above as a root manager, the NewClass instance is created in Control_Panel/Products/NewProduct/. If I try: <a href="/Control_Panel/Products/NewProduct/summer/jdh/newtest/NewClass_addForm"> add a new class </a> which from my read of the zope book is how it should be done, I get the error: Error Type: NameError Error Value: global name 'NewClass' is not defined The offending line in NewClass_add is <dtml-with "NewClass.createInObjectManager(REQUEST['id'], REQUEST)"> Can someone advise me how to proceed to enable a properly authenticated user to add a NewClass instance without visiting the manager interface? Thanks, John Hunter

RE: [Zope] Problems adding attribute to custom object
by Jean-Francois.Doyon＠CCRS.NRCan.gc.ca 02 May '02

Hello, Thanks for the suggestion, I'l take a lok at that ... As for the Object, it's completely custom in that I wrote it and doesn't subclass anything else. I obviously used the other CMF types as a base to write my own though ... I guess I'll have ot look at how I wrote it, but from looking at others such as CMF document and son I don't *think* I missed anything. J.F. -----Original Message----- From: complaw(a)hal-pc.org [mailto:complaw@hal-pc.org] Sent: Thursday, May 02, 2002 12:31 PM To: Jean-Francois.Doyon(a)ccrs.nrcan.gc.ca Cc: zope(a)zope.org Subject: Re: [Zope] Problems adding attribute to custom object Is your new class completely custom, or did you derive it from an existing class (e.g., DTML Document)? Something that has worked for me in the past is to do a search on the set of objects... for obj in context.objectValues('MyClassMetaName'): .. and then use the base class addProperty method to add the additional property. You can also put a try/except block in your code to handle exceptions. Hope that helps. Ron > Hello, > > I'm trying to add a new attribute to all objects of a certain meta_type on > my site.
