"http://www.zope.org": HORRIBLE HTML
by Svante Kleist 09 Jul '00

Has anybody tried to validate the Zope homepage? Like so: < URL: http://validator.w3.org/check?uri=http%3A%2F%2Fwww.zope.org%2F > My attention was drawn to this sad fact when I reported (was I thought was) a bug in Mozilla: < URL: http://bugzilla.mozilla.org/show_bug.cgi?id=44757 > Is Zope buggy, producing HTML like this?

Resizing uploaded image in external method with Pil
by Anja DeRidder 08 Jul '00

Resizing uploaded image in external method with Pil Peter Sebrechts sebrechts.deridder(a)pandora.be Hello, I have a Form, where I can select an Image to upload, combined with several fill-in fields for the Image-properties. The Form starts with: <form action="add_newImage_html" METHOD="POST" ENCTYPE="multipart/form-data"> The uploadfield is: <input type="file" name="newimage" value=""> Next are the other input-fields and the Submit button. -------------------- The uploadform and the DTMLmethod 'add_newImage_html' reside in the folder 'Images', where the new created image-objects are stored. In each image-object is the uploaded newimage stored, and also a subfolder, where a new created thumbnail from the original image is placed. The resizing to a thumbnail is done in an external method with Pil. And here is my problem: I can pass an Image trough an external method without resizing it. However, when I try to open it with " im = Pil.Image.open(newimage)", I receive an errormessage: 'cannot identify image file' After long searches in the Archives, I'm aware that it has something to do with making the image-data available as a string or as a file-handle. After many trials, I've got only errors... The dtml-method 'add_newImage_html' is as follows: <dtml-with REQUEST> <dtml-if "newimage.filename"> <dtml-call "REQUEST.set('IDnr',REQUEST.form['new_ IDnr '])"> <dtml-with "manage_addProduct['ImageProduct']"> <dtml-call "Imageclass_add(_.None,_, NoRedir=1)"> </dtml-with> <dtml-in "objectValues(['Images'])"> <dtml-if "(_['sequence-item'].id == REQUEST.form['new_ IDnr '])"> <dtml-call "REQUEST.set('new_ArtNo',_['sequence-item'])"> </dtml-if> </dtml-in> <dtml-call "_['new_ IDnr '].manage_addImage(newimage.filename,newimage)"> <dtml-call "_['new_ IDnr '].manage_addFolder('preview')"> # until now, everything is OK: image-object is created, image stored and previewfolder created. #now, I try to make a thumbnail and store it in the 'preview' folder: <dtml-with "_['new_ IDnr '].preview"> <dtml-call "manage_addImage(newimage.filename,thumbmaker(newimage))"> </dtml-with> -------------------- The external method 'thumbmaker': def thumbmaker (self,newimage): """convert image to preview-size (128 x 128) """ import Pil im = Pil.Image.open(newimage) im = im.thumbnail((128,128)) return im I tried also: im = Pil.Image.open(StringIO(newimage)) # (with StringIO imported) and in the dtml-method: <dtml-call "manage_addImage(newimage.filename,thumbmaker(str(newimage)))"> and passing via REQUEST.newimage from the dtml- to the external method and finally refering to the already stored image was also without result. Ps: I know that Photo does something similar, but it seems me not easy to combine with my multi-inputfield uploadForm. Peter

strange catalog problem
by ed colmar 08 Jul '00

08 Jul '00

Here's a weird one. I'm testing out my products catalog functionality, and I'm seeing strange results. I add an object "A" with an indexed variable called 'styles' that contains the values: ['Ambient', 'Breakbeat', 'Downtempo'] I add a second object "B" with the varaibles: ('Ambient', 'Breakbeat', 'Downtempo', 'Hardcore', 'Hip-Hop', 'House', 'Jungle', 'Techno', 'Trance') When I search for these varables, the results get somewhat mixed up. 3 incorrect searches out of 8. search for: results: Ambient B* Breakbeat A&B Downtempo A&B Hardcore A* Hip-Hop * House B Jungle B Techno B Trance B All these variables are inputted through a select box, so the spelling/case should be identical. There's some kind of a pattern here though, I don't quite see it. this is the call that I'm using to index the object: self.Catalog.catalog_object(ob,'Promoters/'+id) Anyone have any idea what might be causing this?

Sorting a list
by RC Compaan 08 Jul '00

08 Jul '00

I have a list: mylist=[('R',31),('I',80),('A',80),('S',23),('E',35),('C',21)] I want to rebuild the list sorted from high to low on the sequence-item. When i call <dtml-in mylist sort=sequence-item reverse> the list gets sorted on the sequence-key not the sequence-item. As I understand the alphabetical characters are the sequence-keys and the float values are the sequence-items. Where do misunderstand? Roché

Richard - A notice was sent out to the list a week or so ago on this - there is a bug in the packing machinery that (as you found) doesn't correctly handle things when you pack to certain time and then subsequently pack to an earlier time. The fix for this is already checked in for 2.2. Brian Lloyd brian(a)digicool.com Software Engineer 540.371.6909 Digital Creations http://www.digicool.com
