You could use FSCounter to do your counting: http://www.zope.org/Members/andym/wiki/FSCounter. There is a How-To on using unique_ids: http://www.zope.org/Members/andym/FSCounter/unique_ids In your code try explicilty using an int: > <dtml-call "REQUEST.set('my_number', _.int(my_number) + 1)"> -- Andy McKay, Developer.

unicode,python20,SQL DB Adapters
by Philipp Auersperg 11 Dec '00

11 Dec '00

Python 2.0 has unicode support and once Zope will officially run with it -> has anybody evaluated how several database adapters will be able to read and write unicode varchars ? (of course only if the DB supports unicode :) DB's with my special interest are: Oracle MSS SQL Server and the database adapters: mxODBC ZOracleDA ZSybaseDA thanks in advance phil

Incrementing a form field
by César A. K. Grossmann 11 Dec '00

Hi! I have a form that is used to insert some records to a database, and one of the fields is a sequence number. I want to increment this number when the form is used, unless is the first time it is loaded. The form (idea copied from the SmartForms HOWTO) have the name "Register", and is something like this: <dtml-var standard_html_header> <dtml-if "REQUEST.REQUEST_METHOD=='POST'"> Record inserted. </dtml-if> <dtml-if my_number> <dtml-call "REQUEST.set('my_number', my_number + 1)"> <dtml-else> <dtml-call "REQUEST.set('my_number', 1)"> </dtml-if> <form action="Register" method="POST"> A Field <input name="my_field" value="some value"><br> A Number <input name="my_number" value="<dtml-var my_number>"><br> <input type="submit" value="OK"> </form> <dtml-var standard_html_footer> It work for the first load, but when I press the OK button, I get an error message: Error Type: TypeError Error Value: illegal argument type for built-in operation The traceback:  What is wrong? How do I increment the value? []s -- +---------------------------------+---------------------------------+ | César A. K.

Re: API and namespace

Rehi Sven, thanks a lot for your patience with the dummy - which is me :) Sorry to say that my problem consists even when applying your snippet. Your statement <dtml-with "_.getitem('NewFolder')"> looks fine to me, but ZOPE insists on creating the new document in /OldFolder instead of /OldFolder/NewFolder Some more stuff for wondering: If I do a <dtml-with "_.getitem('NewFolder')"> <dtml-var "_.getitem('NewFolder',0)"> to get an actual value for testing purposes, ZOPE returns the *correct* value. But if I do an additional <dtml-in objectItems> id: <dtml-var sequence-key>, type: <dtml-var meta_type> </dtml-in> to get the objects in the actual namespace (surely *after* the above <dtml-with..>, the output is the one of the /OldFolder-namespace, not that of the /OldFolder/NewFolder. ...I'm sure this is a rookie-problem and can be solved by turning a switch or two (perhaps in my brain), but I'm stuck. Do you/anybody has any clue?

RE: [Zope] Using Analog and Zope Zserver
by sean.upton＠uniontrib.com 11 Dec '00

A thought for you. We use analog, and I talked with the person here that implements it, and he wasn't sure there was a solution. However, you could try this: Set up analog so that all requests are seen as pages Write a shell script to filter lines from your server log using grep to search using regexes, piping the output through grep as many times as possible to run each regex that you need; the final output should be only pages. A pain, but once it is automated, you should be ok.

Or perhaps more accurately everything without a "." in it's name. I have read numerous posts to this list regarding index_html or *_html, but much of my site is composed of Zwiki pages, which do not follow that convention. I'm currently playing with the regular expression functions, but I'm not exactly familiar with regex. Any ideas? What is everyone else using when using Zserver, vs. Apache, IIS, etc. Thanks - Scott _______________________________________________ Zope maillist - Zope(a)zope.org http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )

PCGI crash problem with SQL/LIMIT
by Mayers, Philip J 11 Dec '00

11 Dec '00

I'm running Zope 2.2.4 and am having a *very* annoying problem (either I'm missing something, or Zope is broken). I've got an SQL table called "users". An SQL query of the form: select * from users limit 10 Works, but: select * from users Fails spectacularly - pcgi_publisher crashes with the error message: Temporarily Unavailable The resource you requested is temporarily unavailable - please try again later. (116) unable to connect, fd=6 I then get a 20 second timeout while PCGI restarts Zope. Grr. Help please Regards, Phil +----------------------------------+ | Phil Mayers, Network Support | | Centre for Computing Services | | Imperial College | +----------------------------------+

Patch to avoid hypenation variables and more
by Tino Wildenhain 11 Dec '00

11 Dec '00

Hi there, finally I want to release my patch for the in-tag. I hope it finds its way into the source-tree. I was sick writing such ugly constructs as _[_['sequence-item']] and so on, so I patched DT_In.py and DT_InSV.py (in lib/python/DocumentTemplate) to use sequence_item as well. All hypenation variables have now a second representation with underscores instead of hypenation. I hope, some time we can drop these hypenation variables. The second problem is if you put one in-tag into another. You have to use <dtml-let> oder REQUEST.set() with variables of the outher in-tag to be able to reference them in the inner loop. The code becomes very ugly this way. So my idea was to give the in-tag an optional argument, called "prefix" to prefix all the sequence-variables with a custom identifier. So you can write: <dtml-in some_sequence prefix="outer_"> <dtml-in some_other_sequence> <dtml-var outer_sequence_item>:<dtml-var sequence_item> </dtml-in the inner sequence> </dtml-in the outer sequence> What do you think about this? Attached are the patch files (g-zipped) They are a bit of size, but I choosed to send them as diff, as requested to avoid flames ;) (Althought the original files would be similar in size) If someone wants the whole files, feel free to write to me) Regards Tino

regex vs ts_regex
by Ross Lazarus 11 Dec '00

11 Dec '00

Apropos http://www.zope.org/Documentation/How-To/ThreadSafety Am I missing something here? There seem to be a number of places in the current 2.2.4 source where the python regex module is used - not ts_regex, thus apparently violating your advice on thread safety? For example, I was just spelunking through /lib/python/AccessControl/User.py, App/Product.py so I started greping a few subdirectories. DateTime.py uses ts_regex as does OFS/ObjectManager.py but NOT OFS/SimpleItem.py ... Is there some reason why it's ok for some modules to use regex rather than ts_regex ??? (I'm resending this to zope(a)zope.org because it bounced from zopedev(a)zope.org - is something broken?)

Re:API and namespace
by Sven Hohage 11 Dec '00

Hi Alexander, I think I've made a mistake. I thought you are about ZClasses. My snippet adds two ZClasses (a folder-like and a document). These Classes are self-defined(take a look at the HowTos or the Developer-Guide"http://www.zope.org/Documentation/Guides/ZDG"). For you this is sufficient -> <dtml- call "manage_addFolder (FolderName)"> <dtml-with "_.getitem(FolderName)"> <dtml- call "manage_add (DocumnetName)"> </dtml-with> Here are some starting-hints: They are all taken from the Zope Quick Reference -->manage_addFolder(id, [title, createPublic, createUserF, REQUEST]) Add a new Folder object with id id. If the createPublic and createUserF parameters are set to any true value, an index_html and a UserFolder objects are created respectively in the new folder. -->manage_addDTMLDocument(id, [title, file, REQUEST, submit]) Add a DTML Document object with the contents of file. If file is empty, default document text is used. -->getitem(name,flag) Lookup a name in the namespace. If the value is callable and the flag is true, then the result of calling the value is returned, otherwise the value is returned. flag defaults to false. You find the reference at -->http://zdp.zope.org/ Hope that helps! Bye

z2.py -i
by Bak＠kedai 11 Dec '00

11 Dec '00

hello all can anybody shed some light on the "-i" option in z2.py. according to the help -i n Set the interpreter check interval. This integer value determines how often the interpreter checks for periodic things such as thread switches and signal handlers. The Zope default is 120, but you may want to experiment with other values that may increase performance in your particular environment. can anybody explain in plain english please. if i decrease the number, what'll happen? if i increase it? what the heck is it anyway? dummy, that's me.. tia -- http://www.kedai.com.my/kk http://www.kedai.com.my/eZine Just bring it!
