Check your file permissions. This is completely unrelated to your original error. -Michel

What would probably be best would be to make our CVS repository public. There, you can checkout a version of our models (many of the models, including PTK, are interrelated). We also use an OD 'file based repository' so it wouldn't be feasable to deliver all of the files to you anyway, and many of the files would contain guts not pertenent to PTK. Not being the CVS guru, I can't give you a timeline. -Michel > Andrew Lahser >

Look on the old website (www.zope.org:8080/) - Amos posted a Product Tutorial that was enough to get me going. It was for Zope 1, but it will still work under Zope2. (although Zope2 seems to have some nicer stuff for products, the old stuff also works). Anthoyn -- Anthony Baxter <anthony(a)interlink.com.au> It's never too late to have a happy childhood.

RE: [Zope] Adding IMAGE with manage_addImage is impossible :)
by Alexander Staubo 24 Oct '99

Are you specifying the encoding type? Images are binary and must be base64-encoded by the browser. (There is also a raw binary transfer method, but I forget whether it is supported by any browsers.) If you omit the encoding type, Zope will not be able to recognize its file type, and it will be handled as plaintext data. Specify the form tag thus: <form action="..." method="post" enctype="multipart/form-data"> ... </form> -- Alexander Staubo http://www.mop.no/~alex/ "QED?" said Russell. "It's Latin," said Morgan.

Adding IMAGE with manage_addImage is impossible :)
by Samu Mielonen 24 Oct '99

24 Oct '99

I can't add an image from a submit form using manage_addImage regardless of whatever I do. Yes, I've read all the documentation (even the source code for image) 10 times already :) I can only manage to save the path of my image (from my local harddrive) as content type text/plain when I use the manage_addImage to try and save the submitted image (not the path). I do not understand what I'm doing wrong. I've tried every single piece of code on the Zope mailing list since 1998 (from archives) concerning manage_addImage and I can only conclude one thing: Adding images is way too difficult :) Here's what I try to do (simplified): within a context of a sub-sub-folder (name is, say 'xyz'): edit.html ========= <form action=postit method=post> <input type=file name="image1"> <input type=submit value="Tallenna muutokset"> </form> postit ====== <dtml-if "image1"> <dtml-call "manage_addImage('temp_img', REQUEST.image1, 'testing images')"> </dtml-if> and the result is a corrupted image file of content type "text/plain" with the size of of my image path in bytes. Both edit.html and postit are inside the same folder and my folderish object can contain image type sub-objects. What am I doing wrong? From above it seems that image1 is a string object, but if so, then where's the uploaded file I'm sending through the submit form? How do I reference it? Is there any way to list all submit form property names (variables) and their contents (values) so that I can easily debug any problem like this? Once again, all help is very much appreciated. Best regards, Samu Mielonen PS Having browsed through all of the Zope mailing list archives I've noticed I was alone with this problem. At least 8 other people had the same problem as I did. How can referencing a simple image object be so darned difficult? :) -- "Our reflections on the order of society, as well as nature, are still dominated by the Newtonian image of massive power, exerted by sovereign agency through the operation of central force..." -Stephen Toulmin, "Cosmopolis"

Are you planning on having MFI or PortalObjects subclassable by ZClasses? ZClasses that subclass PortalObjects might participate in the PTK system (create, review, reject or publish & catalog) without creating a product. Will there be a SQL Method interface for storing PTK objects in a RDBMS? Or will PTK objects only be storable in the ZODB? > A familiar rhythm I'm looking for is 1) release an alpha, 2) someone > points out a problem, 3) that person, using the model, describes exactly > how they think it should work.

Creating Products in Python
by gtk 24 Oct '99

24 Oct '99

Okay, I've ripped apart the source for multiple products and I *still* can't figure out how the hell to code a basic Product that implements an item that can be managed by Zope. I've stopped the tracebacks from occurring, but the item never appears under "managed items". What's the "hello world" of Zope Products implemented in Python? What's the best way of forcing a product to reload? Deleting it, adding it again and restarting Zope is becoming somewhat tedious. Regards, Garth. -- <gtk(a)well.com>
