Transparent Folders
by Brenton Bills 11 Dec '00

11 Dec '00

Hi, v0.2 I attempting to use transparent folders. Like Andrew Milton's suggestions on using them to unclutter your tree, I wanted (want) to put all SQL methods in a folder in the root of my zope tree. From under this I wanted to put various tranparent folders grouping likewise functionality, eg, sqlMethods / Students / get_all_students get_all_students_gpa Teachers / get_all_teachers I would like to go, <dtml-in get_all_students> </dtml-in> And reverse aquisition will do its stuff and run the get_all_students in the Students folders. Sadly its not working though, am I correct in thinking that this functionality exists? Am I missing a patch or something? Thanks, Brenton Bills.

access log analyzer (analog, webalizer etc.)
by Martin Winkler 11 Dec '00

11 Dec '00

Hi listies, since we all use names for urls that are not "standardized" - ending with ".html", ".gif" etc - I am wondering how to do a good logfile analyzing with standard tools like those in the subject line. I am usually running zope behind a http-accelerated squid, so I've configured squid to use "emulate_httpd_log on". But how webalizer doesn't recognize whether it's an image or html output. Did someone already write a tool that converts these logfiles like this (or similar): logfileconverter reads the logfile line by line --> checks against the ZODB whether the url outputs a "jpg", "gif" or "html" --> converts the line in the logfile accordingly (e.g. "/mydir/mymethod" to "/mydir/mymethod.html" and "mydir/mypic" to "mydir/mypic.jpg") --> then saves the modified logfile to disk or pipes it to webalizer. Thanks for your input! Martin

Why I Love Zope: Success Stories (BEWARE: sappy stuff inside)
by J. Atwood 10 Dec '00

10 Dec '00

I run at least 7 or 8 Zope sites of varying shapes and sizes for about a year now and everyone once in awhile I just have to take a moment and reflect upon how much easier Zope has made my "web" life. There are some of my stories (que the music) - Recently someone took notice of a FAQ on one of my sites (thank you KnowledgeKit) and was trying to figure out how I kept it updated and allowed for user submissions. As I told them about the process (submit, email, edit, approve, go live and added to "new FAQs") I just realized how cool the system really is and how much easier it had all been to do in Zope. The kicker was when I mentioned I had the same system for the links (Thank you SimpleURL). They were stunned, to say the least. Go Zope. - My Brother recently had a child and not only was I able to set my new niece up with a area on the family site but gave my Father a username and password and about five minutes of instructions on how to get images into the photo album (thank you ZPhotoAlbum). I went to bed while he scanned away and published a series of pictures all by himself. Not only was he totally impressed with the system but in the content management features. Of course a link went out to all the family to come and take a look. Zope can now add a new tag line "Father Friendly." - I have been slowly getting Zope into more and more projects at work. We are now at about 5 Zope sites. This really shouldn't seem that amazing except for the fact that I in order to build the very first site in Zope I had to battle for about two weeks with arguments, case studies and ultimately putting my job on the line. Now, when building a new site they don't even question what I will build it in. Zope is CEO friendly as well. - Two of our sites at work were built at the same time. One in Zope one in JSP. Everyone worried about the Zope and how it compared to JSP (Tomcat). Fast forward a few months when the consultants who built the JSP site are gone and the two sites need content management and updating. I spent a little time with one user teaching them how to update some stuff with versions etc and they have been happily doing so ever since. The person who is responsible for keeping the JSP site updated has been struggling with code, FTP issues, compiling problems, etc. After about a month of struggling with her updates and changes she noticed the other user easily go in through his browser, do a quick change and make it go live. Fireworks erupted. She had a TIZZY! "DID YOU JUST CHANGE THE HOMEPAGE THAT EASILY? HOW CAN YOU DO THAT? WHY CAN'T I DO THAT?! OH MY GOD!!" To which he simply replied, "I don't know... I think it is cause it is Zope" (not really knowing what Zope was at all). (last one) - We were building a new brochure site (simple, graphic, etc) and the graphic artist who knows a bit of HTML but mostly works in DreamWeaver and has done a few Zope updates and image uploads in Zope before is heading the project. I set up a Zope server for him, gave him a username and password and basically went on to another project. A few weeks go by and I went to check to see how things had been going thinking that he would probably need me to get the data up there and start building the site in Zope. Not only was the site already built with DTML navigation that he had put in for location specific buttons but he was working on the second version of the entire site in a version. I was totally stunned. Just a nice set of stories for you to share with your peers when they ask you why you should/would or do use Zope. If anyone else has similar stories it would be nice to hear them. Cheers, J

HTTP status code 302
by Hung Jung Lu 10 Dec '00

10 Dec '00

I can view certain document on a Zope site over the web if I use a brower. But for fun I tried to download it by using Python's httplib, and for some Zope sites got a status code 302. This probably means I need to use another URL address. The web browser does this automatically so I don't need to do anything. But I can't seem to find the right URL. Reading from http://www.w3.org/Protocols/HTTP/HTRESP.html , it says that when 302 happens, the header line would be URI: <url> String CrLf But I don't see this line in the returned header. And the returned body is an HTML telling me the document has been moved. Funny thing is that browsers (IE, Netscape) do not have problems with it. Is this a limitation of Python's httplib (not showing the URI in the response header)? Is there a way to circumvent it? Or does this have to do with virtual hosting, or Apache stuff? Thanks, Hung Jung

Do you > know > any pointer where I can get info on all the headers? This is the specification for http 1.1 http://www.faqs.org/rfcs/rfc2616.html esp. Section 14 for headers, you'll also find 302 and friends explained in this document. and for more pointers http://www.w3.org/Protocols/ cheers, oliver

I am not sure what your problem is here. Are you talking about the fact that if the checkbox isn't checked, that the browser doesn't send *any* information about the field 'current_college_student'? If so, you can check for it's absense with the DTML construct '<dtml-unless current_college_student> .. </dtml-unless>. Or you could add a hidden form field *before* the checkbox which defines a default, empty value, like so: <input type="hidden" name="current_college_student:default" value=""> You can of course put any other value in there. The browser will always pass this back to Zope, and then you can test for the value of current_college_student. Hope this helps! > It seems so simple, I'm almost embarrassed to post my question to the > general zope mailing list. Well, it wasn't so simple that you could figure it out on your own. There may be other people that struggle with this, and they would benefit from your questions and the answers you may receive. -- Martijn Pieters | Software Engineer mailto:mj@digicool.com | Digital Creations http://www.digicool.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

I think that the confusion here lies in the word, "Peristent". Because it uses the standard Python pickling mechanism, the ZODB can store all kinds of objects (integers, strings, etc., as well as class instances). The ZODB is, however, broken up into a collection of individual records, each of which contains a series of pickles (one per transaction). Objects which are not "ZODB aware" get stored in the pickle of their container (actually, the nearest one which *is* persistence-aware). Deriving your class from Persistence.Persistent says to the ZODB, "put me in my *own* pickle, not it the pickle of my container". The other thing Persistence does is hook the '__setattr__' method, so that changes you make to the object's attributes automatically register it with Zope's transaction machinery; this registration means that a new pickle gets saved to the ZODB at the end of the transaction. Objects which do not derive from Persistence must handle this registration themselves, or else risk having such changes be lost whenever they are reloaded. Globals.PersistentDictionary is a wrapper class which does does this kind of registration in its '__setitem__' method.
