UPDATE: Apache + ZServer complete solution
by anser 11 Jan '00

11 Jan '00

Thanks to Evan Simpson (author of SiteAccess), I now have a complete working solution for embedding ZServer behind Apache, allowing all or part of a website to run with fast, multithreaded Zope content while other legacy content and configurations are unaffected. http://www.zope.org/Members/anser/apache_zserver/ Enjoy, and as always I welcome suggestions and comments.

Re: Using MySQL DA - Great HOWTO
by Glenn Williams 11 Jan '00

11 Jan '00

Great writeup on installing ZMySQLDA. I used the How-To and indeed it took less than 10 minutes to get the thing working! As a little bit of additional info: I am running SuSE Linux 6.3, and vanilla version of Python they provide works fine with no modifications. That is, I didn't have to rebuild Python to get it to work... Regards and thanks again, Glenn Advanced Decisions Inc. Running S.u.S.E.

I hope that you did not take my example literaly. I included an extra apostrophe (') in the example that would give a syntax error. Here is a simplier example. <dtml-var "blah(REQUEST, alt='your text', pdcookie='1')"> Add all the additional tags that you would want.

The pdcookie feature is nothing more than a switch to spit out some html. Feel free to copy that anywhere you need. The trick is to set the cookie in the user's browser.

I've tried that before, except I was giving "1" as the flag to getitem. Not that it mattered. It gives: Error Type: TypeError Error Value: illegal name used in expression This showed up when I originally tossed __call__ into the mix, and when I use your version. - Gregor

Although I do see the error there, now that you mention it. Hindsight's 20/20, etc. > Remember that blah needs to > be photo object, not an attribute with the name of the photo Right. That's the problem. I have a string property "image" available to my method, rather than the Photo object it refers to. > If I understand your problem correctly, you should be able to do this. > <dtml-with blah> # blah is an attribute of the index_html document > <dtml-var "tag(REQUEST, pdcookie='1', alt='your text')"> > </dtml-with> Error Type: NameError Error Value: tag Presumably because blah is a string rather than a Photo. - Gregor vorlon#iglou.com

When I go to acl_users and add a new user, it has the same new user page it allways has, including the password. Where, exactly, do you see this behavior? -Michel

adding instance w/o management access
by Timothy Wilson 11 Jan '00

11 Jan '00

Hi everyone, I've got a certain role assigned to people who I want to be able to create an instance of a ZClass. I don't want them to have access to the management screen however. I'm having trouble figuring out what combination of permissions will do it. Does anyone have a suggestion? Currently I have a link that points to the 'NewsArticle_factory' for creating instances of my News ZClass. I'm not even sure if that's the proper way to do it. I do know that everything works perfectly if you have the Manager role. -Tim -- Timothy Wilson | "The faster you | Check out: Henry Sibley H.S. | go, the shorter | http://slashdot.org/ W.

Using a tree in the header?
by Guy Davis 11 Jan '00

11 Jan '00

I would like to use the dtml-tree to allow users to puruse the object hierarchy (DTML Docs and Folders) starting from the root folder (/). I would like it displayed in the left hand column of a table that I set up in the standard_header. This is the closest I got: <dtml-tree branches_expr="objectValues(['Folder', 'DTML Document'])" nowrap=1 sort=id> <IMG SRC="<dtml-var icon>" ALIGN="TOP" BORDER="0" width=16 height=16> <A HREF="http://caldhcp082/<dtml-var tree-item-url>?<dtml-if tree-s>tree-s=<dtml-var tree-s></dtml-if><dtml-if tree-e>&tree-e=<dtml-var tree-e></dtml-if><dtml-if tree-c>&tree-c=<dtml-var tree-c></dtml-if>"<dtml-var id></a> </dtml-tree> However, I don't know what 'name' to use in the dtml-tree tag. What is the object id for the root folder? ( '/' ?) I would like to functionality of the /manage screens, in terms of file browsing, without the use of frames. Is this possible? I'd love to see a working example. Thanks. -- Guy Davis mailto:davis@arc.ab.ca (403) 210-5334 Alberta Research Council

Photo Product fix/question/suggestion
by Gregor 10 Jan '00

10 Jan '00

Question: I have a class "FoobarInfo" that has an "image" property. This property holds the ID of an image to be rendered in FoobarInfo's index_html method. Therefore, in the index_html I was doing this: <img class="fooimage" alt="[Image for <dtml-var name>]" src=<dtml-var image> > And this works just spiffy. However, I want to use the Photo Product instead of the Image class. The code above works for Photo, too, but it does not take advantage of Photo's features. Now, normally you would insert the following into a document to render the image and use the feature I want (specifically, a user's preferred display size): <dtml-var "blah(REQUEST, pdcookie='1')"> Where "blah" is the ID of the Photo instance you want to insert. My problem is that I'm not sure how to say "blah should be the object referred to by my image property", and I'm also not sure how to set the class and alt text in this usage (putting them after pdcookie didn't work). I've tried all sorts of weird stuff with _, getitem, dtml-with, dtml-let, but to no avail. Alternately, figuring out how to use this "pdcookie" feature from a normal <img> tag would work too. (I also tried deriving my class from Image or Photo and adding my extra Info properties, but that was even harder to figure out. At least this way it sort-of works.) Fixing the default Image Formats: The __init__.py file that the Photo Product supplies for PIL only supports the GIF image type by default, which is weird behavior these days. I thought it was a bug at first. ;-) To enable other formats, open the __init__.py that you put in PIL's directory, and add the desired Image plugins onto the import list. Mine looks like so, now: import Image, ImageFile, ImageDraw, _imaging, GifImagePlugin, JpegImagePlugin, PngImagePlugin This seems to work fine. All of the plugins are in PIL's directory, so look there to figure out whether one is available for a given format. (I plan to remove GifImagePlugin, because frankly I never use GIF if I can avoid it). Suggestion: As far as the Photo Product itself is concerned, I think that the default size for thumbnails is way too huge. 128x128 seems more alike a preview size than a thumbnail (I would put the latter at more like 32x32 or 64x64). I know I can fix it (says so right in the docs), but I thought I might put in my 2 cents on that ;-) - Gregor vorlon#iglou.com http://anime.at/gregordyne http://www.skysys.org/~gregor Anime, Amber, 3d, Mage, Eidolon, Miscellany

Hmm... might be a bug in the v1-v2 conversion script. Can you copy and paste this folder to another location? Does it still bug out if it does let you copy/paste? Do you get any errors in your log like "Cannot load state for object 0F0000.... etc... " -Michel
