OK, i managed to call manage_edit on the dtml-document SomeDoc and change it's included text: <dtml-call expr="SomeDoc.manage_edit('some text','')"> So, how can i do this if the id of my document is stored in another variable? e.g. <dtml-let doc_id="'SomeDoc'"> <dtml-call expr="???"> </dtml-let> Thanks Bernd -- -----Bernd Worsch-----------bernd.worsch(a)frontsite.de--------

Hi Zopists, I have a list of user e-mail addresses which is created dynamically. I would like to use <dtml-sendmail> tag to send an e-mail at all addresses in my dynamical list but do not know what the syntax of mailto attribute in sendmail tag shoul be. I have tried: mailto=mail_list (mail_list is list the list of e-mail addresses) but it doesn't work. And when I tried to create To: header dynamically then some error that RCPT is missing has appeared. I use Zope 2.1.6 Any idea, please help me.

Hi! I'm having a similar problem, but I don't even get the objects in the Catalog. I must click on Find Objects. And yes, I created the ZClass with CatalogAware Base... (Zope 2.3.0 binary release, python 1.5.2, linux2-x86) Thanks for any help.

Hmm weird!
by Phil Harris 19 Mar '01

19 Mar '01

Sorry for the obtuse subject but, let's see if I can explain, and let's see if other people are seeing this: I've got this DTML page: <html><body> <h2><dtml-var title_or_id></h2> <a href="index_html">click here to refresh</a> </body> </html> OK looks fine, but the interesting bit is the anchor at the bottom. Depending on the URL typed into the browser address bar I get different results (but I think they should be the same results). If I put http://localhost:12380/test I get this result: <html><body> <h2>index_html</h2> <a href="index_html">click here to refresh</a> </body> </html> Notice the address in the anchor it looks ok, but If I put http://localhost:12380/test/ into the address bar I get: <html><body> <h2>index_html</h2> <a href="index_html">click here to refresh</a> </body> </html> Which I have to admit looks identical, *BUT* the anchor takes you to different addresses. The first one takes you to the index_html in the root, the second one takes you to the index_html in the test folder as it should. If anyone can understand what I'm going on about and if then any of you have any ideas, *please* let me know. I'm not sure if this is a Zope problem (I don't really see how it could be since the address is the same), or if it's a browser problem. However I'm dead confused here. I can't publish the real address for you top verify this, your going to have to believe me or test it yourself. tia Phil phil.harris(a)zweb.co.uk

Newbee problem
by egbertei 19 Mar '01

19 Mar '01

I am absolutely new to Zope. I like to use it, but can not. I can not log into zope. Several days of trying an reading all the documentation available to me have not produced the result of logging into zope. I am therefore trying to obtain some enlightenment here. So please help. My system: I work on a laptop computer with 128MB memory and Pentium III processor. Operating system: Linux Mandrake 7.2. The following packages of zope are installed via RPM: Zope Zope-components Zope-core Zope-services Zope-zpublisher Zope-zserver Zope-ztemplates When the computer starts up there appears a message: Starting Zope [OK]. When I bring down the computer there is a message: Stopping Zope [OK]. The following Zope related files appear in the directory /var/run: pcgi.soc and zserver.pid There is also Apache installed on the computer, starting automatically . When I go to to the local URL http://localhost.localdomain, then the apache webpage appears. There are only error messages when I try something like http://localhost:8080/manage (or various variations of this). To find out whether a different port number applies to my computer, I searched the file /etc/services. I did not see anything which is obviously related to zope. Port 8080 is mapped to webcache 8080/tcp and webcache 8080/udp. Similarly port 80 is mapped to www 80/tcp and www 80/udp. Speicfying http://localhost:80 also brings up the apache webpage. I have tried to disable the apache daemon httpd, but then I can not see the URL. Now my question: what do I need to do in order to be able to get going, i.e. to log into zope to start with. Is this a configuration problem? According to the Zope Content Manager Guide, everything looks so easy, but no information is offered on how to log in in the first place. There is a Zope Administration Guide included with my distribution, but that is only for MS Windows, not for Linux (yet?). Is there any document out there which addresses this problem? Any information that can help me to solve this initial hurdle is highly appreciated. Thanks in advance. Egbert Eissing.

Newbie Questions
by Kenneth Ellested 19 Mar '01

19 Mar '01

Hello, I'm new to Zope and I've used it for a week or so to try and figure out how it works. I'm used to OO programming with Delphi and other tools, so I'm very interested in what Zope can do on the Web. I have worked out the examples, and done some investigation on my own, like itterating through line(s) properties, calling methods with parameters and so, and everything works fine and very stable. But as a Newbie I have some questions that it will take me some time to figure out on my own, so I'm trying to reach some of you experienced developers out there. 1. Uploading files/images (>500K) seems extremely slow. Maybee it's related to a huge memory overhead, not dividing the incoming stream into smaller chunks or so. Can anyone verify this ? A 3MB pdf takes over a minute to upload (locally). If I use my own ISAPI extension on IIS5 it takes less than 2 seconds - and I dont't believe that native code runs that much faster. Of course I can't compare against an underlying ZODB, but still it's quite a difference (>1000%). 2. When speaking of speed, it's quite interesting that all the sites that I have visited on the "who uses zope" list are quite slow. The more images the slower the sites load. Well, someone may say that this is natural - but I think the difference is more than just a simple increase in the bandwidth. It seems to go deeper than that, and maybee it's related to Q1. Anyway, I'm not so concerned about speed, as it can be overcommed with faster hardware, but I'd like to get some prediction on how fast machines I have to use with a graphically rich site. Currently I'm meassuring on a 800MHz PIII with 256MB Ram. 3. How do you set up the ZCatalog to index native html, pdf and other files (if possible). As far as I understand, the ZCatalog is working on object properties. I've tried to upload a couple of PDF files, and add an application/pdf meta-type to the catalog, but I guess that I'm not even close. Maybee it's just a question of using the loadsite product which I guess put native html content into some properties. But what about PDF files, can ZCatalog index these ? 4. Link integrity. One of the things I've noticed is that objects and internal links between them may be hard to manage when you start moving objects around. Some would say that you should just avoid it, but I'm afraid that this is not possible in the long run. How do you manage link (object references) integrity in huge sites. Dividing f.ex. a large folder of objects into smaller groups may brake a lot of links on the site. In a traditional environment, the editor (or server) will manage the integrity, so when we move a file, the refering files will be updated automatically. Is there any kind of an object notification system or like in Zope, or a way of automatically ensuring integrity between objects ? 5. I will continue to investigate and try out Zope, to get a clearer view of the benefits and drawbacks (if any ;-). So I've decided to try and make a somewhat (more or less) complicated structure. I have worked some time with ASP and VBScript (god help me), and I have a clear view on how to do it with these tools. But as usual this means that productivity equals nothing... I'd like to change that fact ! So I'm hoping that someone may give me an idea of how to do this with Zope. The structure is about product propties/attributes. Say for example that we have 1000 products that we like to let a user create. These products only have small amount of properties in common, so making 200 ZClasses with the right property sheets seems a little overkill. What I would like is to have a large list of possible properties, and let the user make a group (maybee folder like) wich contains the product objects, and then select what properties these products have in common from a multi-select list (for example). So the individual objects will have a dynamic property sheet defined by the group they belong to. Also it should be possible to name the properties without beeing restricted to property ID's (properties/attributes may have spaces in the output). Basically it should work as a table with products on the top, attributes on the left and values in the intersections. I'm not sure about the layout with a group that defines the properties. Maybee it would be better to make a "Table" class that combines a product instance with the properties. Anyway the interesting part is that when I delete a product it's properties should be delete as well. Well, maybee I should have split this message into smaller questions, but any feedback is appreciated. If I ask to much, just let me know - this is my first posting, so please be gentle with me ;-) Regards Kenneth Ellested

Can anyone recommend an inexpensive Zope hosting company? I'm looking for something in the $40 or less a month range (for a hobby-type site). Or is there a way to run it on a host where I have the standard cgi-bin access?
