Hello, I've been tryhing hard for the last two weeks to use zope but I can't seem to get it to go past the /manage resource. I'm running zserver, I tried the default password, changing it with zpasswd, removing domain restrictions, everything, but it still gives me authentication failed. Please help me. I'm going insane here. Thanks for your time =) ---------------------------------------------------------- Universidad Federico Santa Maria - Campus Guayaquil

You can use "ZopeFind" (see the object reference on zdp.zope.org for a documentation) with obj_expr='_.hasattr(aq_explicit,"your_property")' You will need Zope 2.2.1 as older Zope version have a ZopeFind bug preventing this use.

Xron TypeError revisited
by Dwayne Morrison 12 Sep '00

12 Sep '00

Hello, I posted earlier about Xron 0.0.9 event scheduling woes. One of my stabs in the dark seems to work. I removed the 'this()' parameter entirely and now am able to schedule events via DTML. I also had to add the 'US/Eastern' parameter to the DateTime call to get a current value for DateTime. It was returning 12/31/1969. Xron documentation (works on Zope 2.1.3): <dtml-with "manage_addProduct['Xron']"> <dtml-call expr="manage_addXronDTMLMethod( this(), 'SchedMethodId1', 'Scheduled Method 1 Title', file = 'Content-Type: text/plain\n\nBANG!!!', executeAt = _.DateTime()+14 )"> </dtml-with> Here's what works for me on 2.2.0: <dtml-with "manage_addProduct['Xron']"> <dtml-call expr="manage_addXronDTMLMethod( 'SchedMethodId1', 'Scheduled Method 1 Title', file = 'Content-Type: text/plain\n\nBANG!!!', executeAt = _.DateTime('US/Eastern')+14 )"> </dtml-with> I'd appreciate any insight as to why this works without the 'this()' parameter in 2.2.0. Thanks, Dwayne Morrison dcmorrison(a)tidewater.net

Zope doesn't start...
by César A. K. Grossmann 12 Sep '00

12 Sep '00

Hi I'm having some strange problems with the RPM version of Zope 2.2.1: it starts, but dies without any message in /var/log/messages. I try to run it by hand, and get these messages: [root@server zope]# ./zserver.sh [root@server zope]# Traceback (innermost last): File "z2.py", line 554, in ? exec "import "+MODULE in {} File "<string>", line 1, in ?

Re: [Zope] 'showREQUEST' or 'show_REQUEST' ?

Steve Alexander writes: > I get an error when I try to add a DTML Method with REQUEST anywhere in > the id. > > Actually, the method gets added, but I cannot edit it. > > I haven't found out why yet. The bad code is in "ZPublisher.BaseRequest.traverse": # Make sure that REQUEST cannot be traversed. if find(path, 'REQUEST') >= 0: return response.notFoundError(path) While the comment indicates that "REQUEST" should not be traversed (probably a good thing to avoid complete confusion inside DTML), the code is a bit generous to ensure this as it forbids "REQUEST" to occur anywhere in the path. Almost surely a case for the Collector. Dieter

Making some DTML Documents catalog aware
by Christian Couder 12 Sep '00

12 Sep '00

Hi everybody, I have a Zope site with many DTML document and I would like to make them catalog aware because I want the web site users to be able to search the site. The web site users are already able to modify the site themselves and this functionality must be kept. I use the debian zope package version 2.1.6-5.2. My first thought was to create a new ZClass that inherit from both the CatalogAware and the DTML Document class but it seems to be quite difficult. First the How-To: DTML Zclass ID Bug Workaround helped a little, but when I try to map some DTML methods to some views in the "Views" tab of my class, no tab for the view are displayed for the class instance. I also searched the news and the documentation and it seems that many people faced some problems when inheriting from both CatalogAware and DTML Document. So now I suppose this is not the best way to solve my problem. Do some people have succeeded in something like this ?

Re: [Zope] How to Pass values to a DTML method ??

Stuart Foster writes: > I have a DTML method that is called from a document.

You should include two positional parameters as well: <dtml-var "some_method(_.None,_,param=value)"> Otherwise, you cut the namespace propagation. Dieter

ZSQL
by Tom Deprez 12 Sep '00

12 Sep '00

Hi, I use an ZSQLMethod to query a database. In the result report I try to insert the results of another ZSQLMethod per each record of the first result report. The problem is that the first record shows the correct result of the second result, but that the following records all show the second result report of the first record. Here follow some code snippets: This query (contact_lookup) is called from the second report : select * from CONTACTPERSON <dtml-sqlgroup where> <dtml-sqltest ADDRESS.CENTRE_NO column=CONTACTPERSON.CENTRE_NO type=int optional> </dtml-sqlgroup> Here is the second report (tabular_contact_report) : <dtml-in contact_lookup size=50 start=query_start> <dtml-if sequence-start> <table border=0> </dtml-if sequence-start> <tr> <td><dtml-var CONTACT_NO null=""></td> <td><dtml-var CENTRE_NO null=""></td> <td><dtml-var CONTACT_NAME></td> <td><dtml-var CONTACT_TYPE></td> <td><dtml-var PHONE_NO></td> <td><dtml-var EMAIL_ADDRESS></td> </tr> <dtml-if sequence-end> </table> </dtml-if sequence-end> <dtml-else> None </dtml-in> And here is a piece of the first report ( tabular_address_report): <dtml-in address_lookup size=5 orphan=0 start=query_start>  <tr> <td colspan=2> <table width="100%"> <tr> <td width="3%"> </td> <td bgcolor="#EEEEEE" border="0"> <dtml-var CENTRE_NO null=""> <small><b>Contactpersons</b></small><BR> </td> </tr> <tr> <td width=30> </td> <td> <dtml-var tabular_contact_report> <<<<<<<<<<< </td> </tr> </table> </td> </tr> </table> </dtml-in> It looks like the query is only done with the first request (ie record no 1) and not with the following record. Because the second query returns always the same results (although I call the query with a different where parameter). What am I doing wrong? Tom.
