IŽm trying to run ZOPE 2.0.1 with SUSE Linux 6.1. I get the following message after having installed the rpmŽs and trying to run zserver.sh : bash-2.02# Traceback (innermost last): File "z2.py", line 367, in ? import ZServer File "/usr/share/zope/ZServer/__init__.py", line 123, in ? from HTTPServer import zhttp_server, zhttp_handler File "/usr/share/zope/ZServer/HTTPServer.py", line 111, in ? import thread ImportError: No module named thread Python 1.5.2 has been installed with the official RPMs. No threading support with Linux (canŽt believe that) ? Any work arounds out there ? Raphael -- Warum schreiben Sie nicht tonal? Sie haben doch Talent ... (R. Strauss zu P.

As the guy who wrote this "lame argument", let me point out that if you'd read the whole piece, you'd have seen that I wasn't trying to make an argument at all, for or agains tanything. It's just a statement of fact. However, think about this. If you did not know of the name beforehand, and somebody told you (verbally) about Zope, what would you do? Would you go on the net and look for a www.zope.com? Would you try to find www.soap.com? www.zoap.com? Or would you respond, "Hmm.

ZClass containing another ZClass
by Itamar 18 Oct '99

18 Oct '99

ZClass Container inherits from ObjectManager. I add inside the aforementioned ZClass another ZClass - ZClass Thingie. I want Containers to hold Thingies, so I go to the Subobjects tab of the Container ZClass - and Thingies are not in the list of objects. Once again, I must be doing something wrong.

converting objects from one type to another ...
by Darran Edmundson 18 Oct '99

18 Oct '99

I have created a ZClass called DImage which acts as a container for multiple Image objects and files. (I use it to store the same image at different resolutions and in different formats.) What I need to do now is convert all of my existing images over to this new object type. As a Zope Image instance only contains one image, the DImage instance will similarly contain one image. I have toyed with the idea of exporting my Images in XML format and then making changes to this text file before reimporting. Possibly it would be easier to write an external method that creates a new DImage instance, populates it with data from the Image, deletes the Image, and then renames itself. Any advice are pointers to solutions that I can use for inspiration and code are appreciated. Cheers, Darran. -- Darran Edmundson [Darran.Edmundson(a)anu.edu.au]

Re: [Zope] Zooming images
by Jeff Rush 18 Oct '99

Hi Rafael, There are two approaches to your image sizing problem, neither of which are Zope-specific. The first is to use the HTML IMG tag with varying sizes and let the browser resize the image: <IMG SRC="photo1.png" HEIGHT=100 WIDTH=100> -or- <dtml-var "_.vars['photo1.png'].tag(HEIGHT=100, WIDTH=100)"> and then for the same image at a different size: <IMG SRC="photo1.png" HEIGHT=200 WIDTH=200> -or- <dtml-var "_.vars['photo1.png'].tag(HEIGHT=200, WIDTH=200)"> And the second approach is to use the Python Image Library to read in and rescale your images, either on the fly (real slow!) or to store two representations as attributes of a object's instance. In approach, perhaps you ought to create a new ZClass called 'Photograph' and provide auto-generation of several image sizes when the image is updated, and a couple of methods that return the image in different sizes. <dtml-var "photo1.thumbnail()"> -and- <dtml-var photo1> for the full-size rendition I am finishing up my "Equation Tiles" python (not zclass) product which uses these techniques. I'll be posting it when done, so you are welcome to use it as a starting point for "Photograph". -Jeff Rush On Sun, 17 Oct 1999 19:21:17 +0200, Rafael Cordones Marcos wrote: >The thing is this cases also contain photos.

I'll be giving a technical introduction to Zope at the upcoming autumn conference of the Dutch Unix Users Group (NLUUG). The conference, entitled "Linux and Open Source for professional use" will be held in Ede, The Netherlands, on November the 4th. Other speakers include John K. Hubbard (The FreeBSD Project) and Colin Tenwick (VP and General Manager of Red Hat Europe).

ZCatalog, CatalogAware, and ZClasses
by gtk 18 Oct '99

18 Oct '99

I'm trying to expand on the ZCatalog tutorial at http://www.zope.org/Documentation/How-To/ZCatalogTutorial by creating a ZClass which automatically maintains a catalog of the CatalogAware items within it. So far, I've created: FnordProduct: Product FnordContainerClass: ZClass derived from ObjectManager Catalog: ZCatalog FnordClass: ZClass derived from CatalogAware ... along with a <classname>Info property sheet each and a matching View to boot. Surprise! When I create a FnordContainer and populate it, the Fnords inside it are catalogued in the ZCatalog in the product. That looks like inheritance (sorry, acquisition:) in action. I assume I need to doctor the FnordContainerClass_add method to create a new ZCatalog in the new FnordContainer. How do I do that? CatalogAwareness.py also mentions: This is a Mix-In class to make objects automaticly catalog and uncatalog themselves in Zope, and to provide some other basic attributes that are useful to catalog. Note that if your class or ZClass subclasses CatalogAware, it will only catalog itself when it is added or copied in Zope. If you make changes to your own object, you are responsible for calling your object's index_object method. Uh, fine. At the moment, I'm only editing my Fnords via their Properties view. How do I doctor the view so that index_object is called? Finally; I've added an index_html method to my FnordContainerClass and used the Z Search Interface pseudo-product (all it does is create DTML methods, and one day I'll investigate and find out how the beggars did it) to create search and results methods. For some reason, it can't find any of the items in the Catalog. Wierd. Any ideas? Regards, Garth. -- <gtk(a)well.com>

I had a similar problem in that I often have various incarnations of the same image (be it gif thumbnail, different resolution jpegs, maybe a postscript version, etc.) My solution was to create a ZClass called DImage. In addition to having some useful properties like a caption, creator, and date, DImage can contain any number of images or files (the postscript). I am still in the process of writing methods (i.e., my product is not ready for public distribution) to render different versions but at least all of the data is encapsulated in a single object.
