Newbie questions: Job_board Howto, ZCatalog, Squishdot
by Meeting Maker Webmaster 10 Jul '00

10 Jul '00

Hello, I've started looking into Zope to build our future sites and from what I've seen, I love it. I have installed Zope 2.1.6 and 2.2.0b3 for my tests, running on a RedHat 6.2 server (Apache with pcgi). I had a few problems / questions I wasn't able to find an answer for in the various documents I looked at. So here is a somewhat long list. I came across a little problem that you will most certainly be able to solve. Basically, I've tried to follow step by step the Job Board howto (http://www.zope.org/Members/mukhsein/job_board_howto) to get familiar with the ZCatalog and the ZClasses. Everything works fine with Zope 2.1.6, but I am unable to have it work under Zope 2.2.0b3. I am always getting a standard authorization dialog box. And none of the users I defined in my /acl_users object work. I've seen that Zope 2.2.0 brought many changes on the security and ownership part. I am certain my problem is somewhere in there, but I am unable to find where ;-) One more comment. On the 2.2.0b3 server, Anonymous isn't allowed to see anything except /index_html page and once logged in (users get a particular local role), you have the same rights as you normally have with Anonymous. I didn't change anything on the 2.1.6 server. I hope this isn't the source of my problem. I've seen in this mailing list that there is a bug related to manage_addProduct... will 2.2.0b4 correct my problem? This brings me to another question. I've added a ZCatalog object in the 2.2.0b3 Zope test server. When I go under "Indexes" and wish to delete one of the indexes, I get the following error message (I've cut the long path to make it more readable): Traceback (innermost last): File [...]/lib/python/ZPublisher/Publish.py, line 222, in publish_module File [...]/lib/python/ZPublisher/Publish.py, line 187, in publish File [...]/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: ElementWithAttributes) File [...]/lib/python/ZPublisher/Publish.py, line 171, in publish File [...]/lib/python/ZPublisher/mapply.py, line 160, in mapply (Object: manage_delIndexes) File [...]/lib/python/ZPublisher/Publish.py, line 112, in call_object (Object: manage_delIndexes) File [...]/lib/python/Products/ZCatalog/ZCatalog.py, line 369, in manage_delIndexes (Object: ElementWithAttributes) File [...]/lib/python/Products/ZCatalog/Catalog.py, line 333, in delIndex No Index: (see above) This works with 2.1.6, so I believe it is a bug, or is it a "feature"? About authorization, on the 2.2.0b3 server, I have redefined /standard_error_message (send an email, other layout, ...). It works fine except with I get the "Unauthorized" message. In that case, after canceling the dialog box for example, I get the error message available in <dtml-var error_message> displayed instead of mailed to me. I've checked that every object used in this standard_error_message method is available to Anonymous (View + Use mailhost services + Access contents information), but it still does not work. Any hint? One last question ;-) I've seen in this mailing list that Squishdot will not work with Zope 2.2.0 until version 0.4.4... when is this version planed? I've tried to install Squisdot on the Zope 2.2.0b3 server and I get the same problem as with my "Job_Board" test... will one solution solve the other? Thank you very much for your help.

DTMLDocument content - "html quoted" or not
by Aleksander Salwa 10 Jul '00

10 Jul '00

I have ZClass (called Artykul) which subclasses DTMLDocument. This class has a method, used to view document, which appends some special stuff to document's content. For some reasons I don't want to put this stuff directly into document's data. In mentioned method, to render document, I wrote: <dtml-var this> But this outputs html quoted text (so I see HTML and DTML tags in browser, instead of formatting and variables). When I render this object from another methods (external to this class), everything works as usual. Is this a bug or feature ? :) _____________________________________________ Aleksander Salwa, ololo(a)zeus.polsl.gliwice.pl An applicant for Zopista

External Method not accepting CGI module
by Kelvin Cheong 10 Jul '00

10 Jul '00

Dear All, I have this python module for uploading an image from a client to the server (which would be subsequently inserted into a MySQL database, which is still on the midst of being resolved). I''m trying to import this into Zope as an External MEthod. It's contents are as follows : import cgi form = cgi.FieldStorage() fileitem = form["userTABPIX1"] fname = tempfile.mktemp() fp=open(fname,'w') fp.write(fileitem.file.read()) fp.close() However, Zope generates this error : Zope has encountered an error while publishing this resource. Error Type : KeyError Error Value: userTABPIX1 Apparently, this piece of code is supposed to work. I grabbed it off the mailing list, and I've compared with the python references and tutorials. Is it because it's not meant to be used as an External MEthod? If so, can anybody suggest a way for me to upload files from the client to the server which will subsequently be inserted into a mySQL db? I posted another message in the archive earlier on which describes my previous attempts in inserting an image into the mySQL database from a form. Thanx, k.c.

wrong day
by Marco Mariani 10 Jul '00

10 Jul '00

Ok, silly me, the date is stored ok, but is reported wrong: <I><dtml-var data fmt="%Y/%m/%d"></I><BR> gives me 1999/12/31 instead of 2000/01/01 -- "This company has performed an illegal operation and will be shut down. If the problem persists, contact your vendor or appeal to a higher court." - Signal11 on slashdot

Patch to DateTime.py
by Curtis Maloney 10 Jul '00

10 Jul '00

Greetings, In my current project, I have to print a lot of dates. Fine, not a problem... _.DateTime().strftime() is just the method, right? Wrong. The people who want this site want the local time, not UTC+0 that strftime enforces. So, I created a tiny patch which adds _.DateTime().strfltime(), which works identically, except it passes LOCALTIME instead of GMTIME. It's tiny, it's simple, but it's REALLY HANDY! Have a better one, Curtis Maloney. <dtml-var standard_work_disclaimer>

help! zope down on it's knees
by Bak ＠ kedai 10 Jul '00

10 Jul '00

greetings and help! my site is experiencing major slow down. connecting to zope takes more than 5-6 minutes. this happens when i got a lot of users connecting. (apache connection > 250). everything works great if i got < 100 user connections what i've done -upgrade apache to serve more than 256 users by editing httpd.h -up the zope thread from the default to a greater number (100) -added more RAM total = 4G when i connect from the server console, with lynx localhost:8080 , i got a long wait with HTTP request sent; waiting for response. ( about 5-6 minutes for a 20Kb file) if i render the page and let apache serve it, the request is served immedietly. i think this has to do with zope inability to cope with requests. i'm looking at putting squid in front and see what happens. or is it my setting? this is happening on a production server and is very bad. help and pointers to tune zope is apprecieted very VERY much this is zope 2.1.6, on RH with SMP and 4G RAM meanwhile, i'll go bang my head before i look at this again. thanks and help, please! -- ------------------------------------------------------ http://www.kedai.com.my/kk Am I Evil?

Am I getting the idea correctly?
by Frank Isaacs 09 Jul '00

09 Jul '00

I'm so new to Zope that I can barely even spell it. But I'm about to spend some time and effort getting proficient with something that enables dynamic, database-connected (and database-updateable) content on web sites so I can sell it to clients, and the appeal of Zope is overwhelming in this arena. I am a very proficient PowerBuilder programmer, but Sybase's offerings are cumbersome and somewhat expensive. I am well versed in many of Microsoft's products, particularly VBA for its Office products, but I worry greatly about using anything from Microsoft because it's hard to know when I'll run into a "gotcha" that I'll curse myself for later on. Cold Fusion and other products seem a happy medium but the CF server piece is about $5k, and some others are more expensive. But here's what worries me about Zope: it looks I will do a whole lot of typing and get caught up in the syntax and repetitive nature of things like <dtml-var ------> and <dtml-this -----> and <dtml-that ----- >. OK, so it's not made for the faint-of-heart at this point - I can handle that. But I also am not an HTML maven, and it looks like I need to have full HTML expertise to make this work also. GUI tools take the drudge out of <a href="something">something and <h2>this is a heading</h2> pretty well, but I don't see how to get out of this stuff with Zope, especially since it looks like everything is stored internally in a data file that I can't access from the outside. Am I correct? Or is there help on the horizon for those of us who have no graphic design skills and <shudder> actually believe there's a place for GUI-based tools? Thanks for any light you might shed on this subject for me - -Frank

I tried STX_Document-1.2, FlexFAQ2 and Yihaw. ZWiki works. I guess this is due to changes in 2.2x, but at least I'd like to know what that erros means (and I'd love to have STX working in 2.2;-) Chris

[Repeat] Nt server w/ Zope
by J. Michael Mc Kay 09 Jul '00

09 Jul '00

Trying again for help. If I stop Zope as a service from NT's Service Manager or from the Zope management interface it seems to kick and scream while restarting. In the application log I see repeated errors stating the service could not start. These repeat until the application log is full. Zope appears to be running, but I have not yet learned how long it is cycling to start. The error series is essentially, "Starting Zope Service" , "Could not Start Zope Service" until the log is full. From there I'm not sure. Is this a known issue or am I missing a switch setting for start-up? This does not occur from reboot. Everything is as normal as I know normalcy. Thanks

Another DateTime Strangeness
by Nils Jeppe 09 Jul '00

09 Jul '00

Zope just stored a DateTime I entered as 13:14 in a slightly odd way: 2000/07/09 13:13:60 GMT+1 Known bug?
