Methods in a Simple Class
by Olivier Deckmyn 09 Mar '00

09 Mar '00

Hi all, I have built a trivial ZClass : CD (from CDProduct, from the guides). I try to add a DTML Method "render_short". This method would render the CD Instance on one short line. My ZClass has simple attributes (artist : string, title : string, description : text) I would like to be able to write this simple "render_short" DTML method like : Artist : <dtml-var artist> Title : <dtml-var title> Descr : <dtml-var description fmt="structured-text" newline_to_br> But when I insert a <dtml_var myCDInstance> in my index_html, I got a exception : Error Type: KeyError Error Value: artist There is no typo in my code... How can I access to my ZClass instance attribute from inside its methods ? Please help me :) Olivier

Re: [Zope] Z2.log and Date stamps 2nd Call for answers????
by Ken Weiss 09 Mar '00

I can confirm and reproduce this problem, and on a totally different architecture - Red Hat Linux system with Zope 2.1.4. Here's a snippet from my /var/log/messages file: Mar 8 10:14:18 akpi ZServer[24689]: 127.0.0.1- - [08/Mar/2000:18:14:18 -0700] "GET /manage" 401 1782 Notice that the timestamp from the syslog facility is the correct local time, March 8 10:14:18, which is Pacific Standard Time. On the very same line, the timestamp passed to the syslog from Z2 is in GMT, 08/Mar/2000:18:14:18 -0700. My guess is that Zope isn't picking up the $TZ environment variable. What I don't get is why it's showing GMT as 18:14:18 -0700. That would imply a local time of 11:14:18. I think it should be 18:14:18 -0800 right now, and -0700 during daylight savings time. Two, two, two bugs in one! --Ken At 12:00 PM -0800 3/8/00, zope-admin(a)zope.org wrote: >Message: 34 >Date: Wed, 08 Mar 2000 10:53:54 -0800 >From: Michel Pelletier <michel(a)digicool.com> >To: CURTIS David <David.Curtis(a)state.or.us> >CC: IPM Return requested Receipt notification requested <Zope(a)zope.org> >Subject: Re: [Zope] Z2.log and Date stamps 2nd Call for answers???? > >We need a couple more data points before we can blame Zope for this or >understand possibly what is happening.

Having slight problems with <dtml-calendar>
by M.J. Stahl 09 Mar '00

09 Mar '00

Problem: Currently I have no problem view the HTML tables of the calendar or adding properities. Where my problem lies is displaying those properties in the tables of the calendar. Currently the variables for the date, whether the object has a property, and the value of that property are registed just like the <dtml-calendar> How-to. <dtml-let d="date.Date()" hasdate="hasProperty(d)" dprop="getProperty(d)"> The 'd="date.Date()"' does what it is supposed to. (make d equal to something like 2000/01/17). I checked the hasdate variable and found that it was equal to a 0 (1 if true, 0 if false, of course). The properties are kept on the folder, where the calendar method is. I added a property via the method for doing such and went back and checked the folder to see if it had a property on it. Yes it did... in this format. Tree Structure: /diis /calendar (contains the properties) index_html (displays the calendar) /updatecalendar index_html (used for editing the properties) 2000/01/17 This is the 17th day of January. Yet, hasdate was equally 0 (false) therefore the 'dprop' value could not be set. I guess my question is this: If the folder containing the calendar method has properties on it which are to be read into the tables of the calendar, does this mean that 'hasProperty(d)' is not being read off the folder and is looking at some other object for the value? If that is not the question can someone please point something out to me that I am doing wrong... All help is extremly appreciated. Best regards, Mark J. Stahl

Re: [Zope] workflow question

Is there any way in Zope to validate information (news, new document) by third party before real publishing. For example some people are alowed to put a document in the folder but these documents must be validate by some one else for real publishing. How can I do this kind of things with Zope? Is it possible? Any suggestion? links? help? [RH] There are several ways to accomplish this: You could put the document in an 'incoming' folder and make a reviewer move it to the publishing location (this also allows for letting the reviewer add keywords/categories etc). If the uploaded document goes directly to the documentation where it is published, you could give it a property called 'approved'; reviewer invokes dtml method which sets the approved property to 1. The document is not shown unless the ' approved' == 1. [untested simplistic dtml] <dtml-unless "approved==0"> <dtml-var <document>> </dtml-unless> I believe the Squishdot product (http://www.zope.org/Members/butchland/Squishdot) allows for something like this. A third (more sophisticated) possibility is to combine the two approaches by using the Catalog, more or less like the Zope site does: contributions by members are submitted for approval to the Zope site administrators, who then add them to the site's catalog. Then they are available in pages that use the catalog for their contents (like the howto pages, the products pages etc). In your case reviewers could also add keywords/categories etc to the document before it is cataloged and the catalog may index these. I do not think the Zope site approach is available for the public, but it shouldn't be too difficult to implement it. A related product is ZDP tools (http://www.zope.org/Members/roeder) which does not exactly do this but may be a source of inspiration for workflow management. Another workflow system in Zope is Xen (I do not have the URL handy right now), but this may be overkill for your needs. hth Rik

Passing arguments to DTMLMethods
by James W. Howe 09 Mar '00

09 Mar '00

I know that there have been several threads on this list concerning the way to pass arguments to a DTMLMethod. I've done what I think is correct, yet my result is less than pleasing. Here's what I have and what I'm doing. Hopefully someone will identify what I'm doing wrong. In my web sites root folder (aka /Foo), I have a DTMLMethod named "siteRoot". It simply answers "Foo". In a subfolder of Foo, I have a method named "linkFor". The code for this method looks like this: /<dtml-var siteRoot>/SomePage?option=<dtml-var optionValue> In the same folder that contains the "linkFor" method, I have another method which wants to use the result of the "linkFor" method. In this method there is a line which looks like this: <a href="<dtml-var "linkFor(_, _.None, optionValue='some value')">">Some Text</a> When this code gets executed, I get a "KeyError" on "siteRoot". For some reason, when my linkFor method executes, it can't see the siteRoot method, even though the method exists in the parent folder. What am I doing wrong? Why can't linkFor see siteRoot? Thanks.

Representing lines as one string
by Kiran Jonnalagadda 09 Mar '00

09 Mar '00

Hi, When I have a form with a <textarea> field set to submit to an sql method, ['it gets stored','like this']. How do I get around this? Do I have to do some special formatting before submitting to the SQL method, or is there something I must do in the SQL method declaration itself? I'm using <dtml-sqlvar fieldname type=string> because this was the best I could find in the documentation. Is there a type=lines? If there is, someone please put it in the ZQR. Another: I want a text holding ZClass for storing text pages. Deriving from DTML Document or Method seems the obvious choice but I have an issue with that: the content must be rendered thus: <dtml-var standard_html_header> <dtml-var raw newline_to_br> <dtml-var standard_html_footer> I suppose I have to override rendering for my ZClass and insert this code. How do I do this? -- Kiran Jonnalagadda http://lunateks.com baby.sh: while true; do echo "^G^G^G^G^G"; sed -e 's/food/poop/'; sync; sync; sleep 15; done
