zope product, object manager problem
by John Hunter 16 Jun '04

16 Jun '04

I have a zope interface Person with a PersonImplementation that inherits from OFS.ObjectManager. When I try to add some product (eg a Folder) instance to an instance of a Person, everything appears to work, but nothing shows up in the listing of the person. Eg if I go to http://my.server:8080/sandbox/jdh/manage_main where jdh is a Person instance, I see There are currently no items in jdh I am posting my code below in hopes someone can point out my mistake. I am trying to follow the code example from the ZDG. Thanks, John Hunter (Zope 2.5.1b1 (source release, python 2.1, linux2), python 2.1.3, linux2) from Person import Person import Products from AccessControl import ClassSecurityInfo from Globals import DTMLFile, InitializeClass from OFS.SimpleItem import SimpleItem from OFS.PropertyManager import PropertyManager from OFS.ObjectManager import ObjectManager class PersonImplementation(SimpleItem, PropertyManager, ObjectManager): """ Person product class, implements Person interface.

Problem converting PIL-generated Image objects to Photo 1.2.3 objects
by Jonathan Cyr 15 Jun '04

15 Jun '04

Hello, I am having a problem converting Image objects generated by PIL to Photo objects (rbickers' Photo & Photo Folder 1.23) in Zope 2.7.0. The error I get is: Error Type: AttributeError Error Value: 'str' object has no attribute 'read' I am uploading an image into Zope, I am using an External Method & PIL to standardize the dimensions & format of the image. The method is extremely similar to the example the the Zope Book example of External Methods & PIL Thumbnail script. At this point, I'd like to take these homegenous image objects and convert them to Photo objects inside a PhotoFolder and take advantage of the render-on-the-fly sizes. I'm using RBickers' script image2photo python script, and I get the above error. Here's the code for the thumbnails, works fine, Images seem fine, work fine, but wont convert to Photo... > def makeThumbnail (self, original_id, original_title, size=150): > """ > Makes a thumbnail image given an image ID when called on a Zope folder. > Modified for WeddingWeblog from code in the Zope Book, Ch10 > > The thumbnail is a Zope image object that is a small JPG representation > of the original image > > """ > > from PIL import Image > from StringIO import StringIO > import os.path > > #create a thumbnail image file > original_image=getattr(self, original_id) > original_file=StringIO(str(original_image.data)) > image=Image.open(original_file) > image=image.convert('RGB') > image.thumbnail((size,size)) > thumbnail_file=StringIO() > image.save(thumbnail_file, "JPEG") > thumbnail_file.seek(0) > > #create an ID for thumbnail > path, ext=os.path.splitext(original_id) > thumbnail_id=path + '_' +str(size) > > # if there's an existing thumbnail delete it. > if thumbnail_id in self.objectIds(): > self.manage_delObjects([thumbnail_id]) > > # create the Zope Image Object > self.manage_addProduct['OFSP'].manage_addImage(thumbnail_id, thumbnail_file, title=original_title) > thumbnail_image=getattr(self, thumbnail_id) > I'm using the Image2Photo script in the Photo/PhotoFolder support, pythonscript: > for image in context.objectValues(['Image']): > context.manage_delObjects([image.getId(),], REQUEST=context.REQUEST) > context.manage_addProduct['Photo'].manage_addPhoto(image.getId(), image.title, image.data, REQUEST=context.REQUEST) I'm not well versed in the object types here... any ideas? -Jon Cyr cyrj(a)cyr.info

Navigation/object relationships
by Michael Ekstrand 15 Jun '04

15 Jun '04

I am working on building a site that contains automatically-generated navigation trees and site maps. Currently, I am using a convoluted system involving properties containing a "navigation level", and am running into problems with that system as I try to extend it to handle more deeply nested parts of the site. What I am looking for is a relatively painless way to determine for an object y, contained somewhere under object x, what is the relationship/containment hierarchy from x to y? Or, at the very least, how do I obtain a given object's container? I have figured out how to do that with path expressions in TAL, but something I can do from a PythonScript would be most useful. Thanks in advance, Mike

Making Magic with Mirrowing Folders
by Gary Duke Speer 15 Jun '04

15 Jun '04

I have been trying to configure Dieter's Mirrowing Folders Product. Using both direct _dtml-var_ links and Shane's AquisitionUnderstander I cannot see the product having any effect. I suspect it is because I do not understand either the product's intention or how to properly setup the mirrow link. For the benefit of other newbies like me, if I am mis-stating the goal of the product or any aspect of it, please say so. My understanding of the intention of the product is that it will insert a distant folder into the acquision path as if the URL routed through that folder, and it does so only when there is exact alignment of the two relative paths. For background, my objective is to have a portable-hole style solution but using only relative urls due to using virtual hosting and other reasons. relative to the site's root folder, there are two primary directory trees - common content files and objects and context-specific files. a simplistic example: .../mysite/ (relative root) .../mysite/common (branch of common content to be mirrowed into other contexts) .../mysite/common/images (folder of site-wide images) .../mysite/common/images/logos/sitelogo.gif (an image to acquire) .../mysite/englishpages (branch of context-specific content) .../mysite/englishpages/page.html (the page trying to access both specific and common content) .../mysite/englishpages/images (folder of context-specific - english language - images) .../mysite/englishpages/images/logos/sitename.gif (an image of the site name written in english) .../mysite/germanpages (branch with identical sub-structure to englishpages and to common) My impression is that .../mysite/englishpages/images is the folder that should be created as a mirrow folder and it should point to the matching common folder. That it's ID is images and it's mirrowid__ property should be set to ../common/images meaning include content that is located up one level from my containing folder, englishpages in a folder called common and in a subfolder called images. The complete magic, compared to transparent folder is that links inside page.html to the logos folder will acquire objects from both logos folders. In other words, a relative link to images/logos/sitename.gif works because the path directly accesses the file. A link to images/logos/sitelogo.gif triggers acquisition because it is not found in the .../mysite/englishpages/images/logos/ folder, so acquisition checks the .../mysite/englishpages/images/ folder, again not found. By operation of the mirrowlink acquisition checks the same subpath of the target, namely .../mysite/common/images/logos/ and should find it. If not, since mirrow is described as subpath specific, aquisition skips checking .../mysite/common/images/ and proceeds to check .../mysite/ .../ and so on up to the Zope root. In short, the mirrow is largely functionally equivalent to using the URL: ../mysite/englishpages/common/images/logos/englishpages/images/logos except that common/images is skipped over. I have tried several variations, including a link to .../mysite/englishpages/images/testimage.jpg in the hopes of returning .../mysite/common/images/testimage.jpg but no luck and .../mysite/common/images/logos/showaq does not look anywhere except each folder of the path. (During this testing VHM is off, tried on both Zope 2.6.1 and 2.7.0 to see if there was a change in the way.) Sorry this is lengthy, but I'm hoping to get my conceptual understanding improved better than I have so far by Googling the archives of this group. Maybe the result will lead to a how-to comparing LinkedFolder, TransparentFolder, PortableHole, Reference, Mirrow Folder, and the toxic Symlink product. Thank you, Duke

Changing the Value of a Form Variable
by Asad Habib 15 Jun '04

15 Jun '04

Hello. Is it possible to change the value of an existent form variable explicitly instead of through a form submission(i.e. can I use <dtml-call REQUEST.form ...> just like I use <dtml-call REQUEST.set ...>). Any help would be greatly appreciated. Thanks. - Asad

Increasing ulimit
by Marc Burgauer 15 Jun '04

15 Jun '04

Hi On a busy Zope instance, we're getting increasingly more often errors of "too many files open". I already added a line in the start script for that instance to increase the ulimit to 1024 (the maximum for the machine by default). I am now considering increasing the maximum for that machine to 2048 (or higher), but wanted to know if other people have experimented with this before and what risks/dangers I should be aware of doing this. Here's what my start script looks at the moment (simplified): > ulimit -n 1024 > python /customer_dir/customer_one/z2.py -X -a212.96.140.5 -w80 This is Zope 2.4 on a Solaris (Intel) box. Cheers Marc
