utf-8 and i18n
by Tim McLaughlin 08 Aug '01

OK, I used shane's tcpwatch to see why one page with Japanese characters (Unicode) rendered properly as kanji whereas the same property set when shown in the management screens (and therefore in a textarea) did not render as kanji, only to learn nothing :( I expected to see the header content-type: text/html followed by charset=utf-8 in the one that worked, but this wasn't true in either... any ideas why one renders as unicode kanji, and the other as garbled junk?

2.3.3 to 2.4 with zctl.py
by Alex Kelly 08 Aug '01

08 Aug '01

I have ZEO running with Zope 2.3.3. I followed the instructions at http://www.zope.org/Members/dshaw/AdvancedSiteSetup to set this up. I wanted to upgrade Zope to 2.4. My thinking was that I should be able to replace my Zope_software_installation directory with the contents of 2.4 and restart Zope. I also wanted to use the zctl.py script that is described in the howto listed above, however when I run that script with 2.4, I get: # ./zctl.py start Traceback (most recent call last): File "./zctl.py", line 332, in ? _dispatch() File "./zctl.py", line 329, in _dispatch globals()[action](args) File "./zctl.py", line 132, in start start_zeo(zeo_args) File "./zctl.py", line 145, in start_zeo if host == 'localhost' and not _check_for_service(host, port): File "./zctl.py", line 301, in _check_for_service s.connect(host, int(port)) TypeError: connect() takes exactly 1 argument (2 given) I can see the line that it has a problem with, and I see that it is trying to pass 2 arguments. What does it take to change that to work with the new version of Zope? Or is there something else I am missing? Alex Kelly

'transparent' proxying to a method not in your namespace?
by sean.upton＠uniontrib.com 08 Aug '01

08 Aug '01

Problem: I have a custom folder type, and I want to hijack unsuccessful method lookups in its namespace and have them transparently proxy to code in another folder... I have a Python product class that uses Folder as it's base; it's cluttered with code objects, and I don't want to have to use Transparent Folders, which seem to break one thing or another. I'm also looking for (perhaps) something as an application-specific alternative/addition to acquisition as a namespace traversal mechanism. I had this idea of storing my various methods in a 'ProjectCode' folder in the Zope root, and having my 'Folder' evaluate its own namespace looking for a method; if it doesn't exist, before the Zope looks in the acquisition parent(s), the 'Folder' looks in the namespace for the 'ProjectCode' (or some other folder name) folder in the root to find the method, and run it within the 'Folder' namespace. I'm sort of ignorant as to where to start looking if I wanted to do this, but I'm willing to investigate and figure out how to code it if it's something that can be done within my product code or in a hotfix, and doesn't require a patch the size of Texas...

DCOracle2 Beta 5
by Matthew T. Kromer 08 Aug '01

08 Aug '01

DCORACLE2 DCOracle2 is Zope Corporation's second generation of its python bindings for Oracle. DCOracle2 is written to use the OCI 8 API, not the OCI 7 API that DCOracle uses, giving DCOracle2 compatibility with more advanced features in newer generations of the Oracle software. RELEASE DCOracle2 Beta 5 is now released, available at http://www.zope.org/Members/matt/dco2 in ZIP and tar.gz formats. Beta 5 is a unified source/binary distribution; the 'install.py' script will attempt to copy the proper binary in place for execution on your system. CONTENTS o DCOracle2 source o DCOracle2 binaries for Oracle 8i (Windows, Solaris, Linux) o ZOracleDA (the Zope Database Adapter) o DCOracleStorage (an Oracle Storage for Zope) INSTALLATION After unpacking, either run 'install.py' to copy an appropriate binary file from the binaries directory to the DCOracle2 directory, or type 'make' to attempt to make a new binary (unix only). For use as ZOracleDA, copy the DCO2 directory to {ZOPE ROOT}/lib/python/Products/ZOracleDA (renaming the directory from DCO2 to ZOracleDA). AVAILABILITY DCOracle2 is available from http://www.zope.org/Members/matt/dco2 immediately. BUG REPORTING Please use the issue tracker at http://www.zope.org/Members/matt/dco2/Tracker to report any issues with DCOracle2.

Zope-Bug affecting my url_quoting (bug in getattr?)
by Jan-Oliver Wagner 08 Aug '01

08 Aug '01

Hi all, I just detected a serious bug: (in short: to my mind getattr() behaves wrong) http://freegis.org/details.en.html?name=Geoprocessamento%3a%20Teoria%20e%20… was produced using <dtml-var name urlquote>. (for those who don't have a browser at hand: the attribute is converted back to Geoprocessamento: Teoria e Aplicaçdetails.en.html5es which is obviously wrong) Manually using capital letters for the url quoting will work (ie. here just '%F5es' at the end of the above URL. Apparantly the %f is substituted by someone by the filename (getattr already delivers this error). Here is the code of details.en.html: --------- <dtml-var standard_html_header> <dtml-call "unquote()"> <dtml-if "_.hasattr(REQUEST, 'name')"> <dtml-var entry_detailed> <dtml-else> Error: there was no name given. </dtml-if> <dtml-var standard_html_footer> --------- And here is unquote() [a python extension]: --------- from urllib import * def unquote_name(self): request = getattr(self, 'REQUEST') if hasattr(request, 'name'): name = getattr(request, 'name') # name already now contains the "%f" substituted by # "details.en.html"!!! request.set('name', unquote(name)) return '' --------- And here is the beginning of entry_detailed: --------- <dtml-with REQUEST> <h2>FreeGIS-summary on <dtml-var name></h2> [...] --------- -- Jan-Oliver Wagner http://intevation.de/~jan/ Intevation GmbH http://intevation.de/ FreeGIS http://freegis.org/

adding a ZSQLmethod programmaticaly throug the WEB
by Joachim Schmitz 08 Aug '01

08 Aug '01

Hi, I resend this quesstion with a little better re-line, and hopefully some better explanation. I try to add a ZSQLmethod by means of a modified load_site.py from the utilities directory of the Zopedistribution. it has a upload_html procedure with the line: call(object.manage_addDTMLMethod, id=root, file=f) which uses the ZClient.py to call the URL: http://www.myhost.de/manage_addDTMLMethod and submit the parameters in the post. this one works. I created an upload_sql: with the corresponding call: call(object.manage_addZSQLMethod ,submit="Add" ,id = root ,template=template ,title="" ,connection_id=string.strip(dbcon) ,arguments=params) but thisone always fails with a "Not found error" for http://www.myhost.de/manage_addZSQLMethod So what is the correct path to the manage_addZSQLMethod ? I am quite sure, that the name is correct Mit freundlichen Grüßen Joachim Schmitz AixtraWare, Ing.

Zcatalog custom index/splitter woes
by Harry Wilkinson 08 Aug '01

08 Aug '01

Hi all. I've customised my own splitter, which works fine when using a standard (non-globbing) lexicon. I also have a customised index, which is working fine. A problem arises when I create a vocabulary that uses my splitter and has globbing enabled. When I do this, the vocabulary reports that it is using my splitter and has globbing enabled, but when I index some things it is evident from the contents of the vocabulary that it is using the standard ZopeSplitter, not my splitter. So far I've put a call to zLOG.LOG in the index_object method of my custom index at the point where the splitter is acquired from the lexicon ( splitter=lexicon.Splitter ) and the log entries are showing two distinct splitters getting assigned when I index objects. Here are the log entries: 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x8250218> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x88b1208> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon ;lexicon.Splitter = <Python Method object at 0x8250218> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x88b1208> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x8250218> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x88b1208> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x8250218> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x88b1208> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x8250218> ------ 2001-08-08T10:15:30 INFO(0) PositionIndex.index_object; splitter assigned from a lexicon; lexicon.Splitter = <Python Method object at 0x88b1208> It looks like maybe my splitter is being assigned but then the default splitter is overwriting it. Anyone got any ideas on how I can fix this? I''ll continue to investigate but I'd appreciate any input :) Thanks. Harry

Problem with StructuredText and expandtabs
by Bill Anderson 07 Aug '01

07 Aug '01

Not being sure where to send this.... here it is. I am trying to use StructuredText outside Zope. I can import it fine, but when I try to use it I get: ====================================== >>> st=StructuredText.Basic(raw) Traceback (most recent call last): File "<stdin>", line 1, in ? File "ST.py", line 113, in StructuredText paragraphs = expandtabs(paragraphs) File "/usr/lib/python2.1/string.py", line 295, in expandtabs return s.expandtabs(tabsize) AttributeError: expandtabs ====================================== I get this on Python 2.1, using the StructuredText from Zope 2.4.0. I have done this on two separate systems now. If anyone has any ideas or workarounds, I'd appreciate it. Also, if anyone can test it against a python 1.5 system, that may be helpful (I've migrated to 2.1 ... pn all available machines). Bill Anderson

TAL problem: getting to one's classes
by vio 07 Aug '01

07 Aug '01

Hello, Could someone give me some hints on how to help TAL get to my classes. My situation is: my classes are in zope/lib/python/Products/MyProduct/. 'mainClass' basically creates a folder object in Zope with a user interface (index_html and such). And this UI basically allows for the creation of various other objects inside this mainClass container. In other words, pretty similar to what ZMI does. So, I create the mainClass using the ZMI itself. Then I can access the UI as normal user from the net (outside ZMI) - namely, I get to the index_html form generated by mainClass. I think the ZMI analogy would be 'manage_addmainClassForm'. But then I can't access my method to process the form, which lives in Products/MyProduct/someOtherClass. My TAL page (or zpt, if you will) is looking inside the mainClass object (folder) for this method, while I want it to look for it in Products/MyProduct/someOtherClass. And I'm having some problem understanding the TAL Tutorials. Hence this message. Any help appreciated. Regards, Vio
