sql varchar truncated?
by Scott Lewis 16 Jun '99

16 Jun '99

hi, i'm having a little problem that i hope someone might have some insight on. i'm using Zope with MS SQL Server 7.0, via the ODBC database adapter. i have a database field called 'description', which is a varchar of length 500. when i write and read back a value via SQL methods, the description string is truncated to about 250 characters. it looks like MS SQL is receiving the full string. if i try to write more than 500 chars, i get a SQL error. if i write less than 500, i get no error. but when i read back the string via a select SQL method, i only get back ~250 characters. i can't verify at the moment what's in the database- i'm FAR away. i've got an email to the DBA to check it out, but i was hoping somewhere here might have an idea of the problem. is a string variable limited to 256 chars in python or zope? i tested the SQL methods directly from zope, to insure that something wasn't happening with HTTP. thanks in advance for any help, -scott included below are the contents of the the two SQL methods (pretty straightforward...): the write method: insert into tblTrainingEvent (Title, Statewide, AreaID, description) values ('', 1, 1,) the read method: select description from tblTrainingEvent where

MVC pattern
by steve＠hosys.com 16 Jun '99

Hello, Does a template exist for implementing an MVC (VisualWorks Smalltalk) like structure for Products. The Product example I have shows inheriting Zope class info and DTML info into the "domain object". I'd like a pattern where the Python objects remain clean, are wrapped by a value model, and linked via the value model with a presentation scheme (DTML). Some code is presented below to the idea across but is not a suggested implementation. class DomainWrapper( OFS.SimpleItem.Item, Persistent, Acquisition.Implicit, AccessControl.Role.RoleManager, ): # Specify definitions for tabs: manage_options=( {'label':'Properties', 'action':'manage_main'}, {'label':'View', 'action':''}, {'label':'Security', 'action':'manage_access'}, ) # Specify how individual operations add up to "permissions": __ac_permissions__=( ('View management screens', ('manage_tabs','manage_main')), ('Change permissions', ('manage_access',) ), ('Change Persons', ('manage_edit',)), ('View', ('','manage_self_edit') ), ) _domainObj = '' index_html = HTMLFile('blank',globals()) def for(self,aDomainObject) _domainObj = aDomainObject def defaultHTML(self, aDTMLFile) index_html = HTMLFile(aDTMLFile) #end class DomainWrapper class DomainObj: #end class DomainObj class Person(DomainObj): _lname = '' _fname = '' _ssn = '' def _init_(self, lastname, firstname,ssn ): _lname = lastname _fname = firstname _ssn = ssn #end class Person p = Person(John,Smith,1112223333) pdw = DomainWrapper.for(p) pdw.defaultHTML('person.dtml') regards, Steve

Iterating over folders with a certain attribute
by Jim Cain 16 Jun '99

16 Jun '99

I want to retrieve the names of all folders that have attribute sequence_id and then iterate over them, while having them sorted by that attribute. I can't do something like:  because not all folders have this attribute. Am I going to have to build an array of these objects, and then iterate over them sorted?

backing up Zope2
by Alex Rice 16 Jun '99

16 Jun '99

Is running "Pack" in Zope still the best way to backup a site? (other than export). What I'm thinking of is like the reverse of utilities/load_site.py. I was trying to FTP an entire Folder and could not. When I 'get' a Folder, it says 550 Error opening file but I can cd into it and 'get' it's contents. Is the Data.bbb format anticipated to change any between Zope 2.a2 and Zope 2.0? Just trying to avoid losing any work. Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N.

solution for alpha2 permissions problem?
by Daniel M. Drucker 16 Jun '99

16 Jun '99

I've been reading the list, but I guess I must have missed it -- what's the solution to the alpha-2 permissions problem that prevents me from running zope as root/nobody so it can be on port 80? Traceback (innermost last): File "z2.py", line 414, in ? pf = open(PID_FILE, 'w') IOError: [Errno 13] Permission denied: '/usr/local/zope2/var/Z2.pid' zinit: Tue Jun 15 16:46:10 1999: Aiieee! 10142 exited with error code: 256

How stable is the 2.0 alpha release?
by Alexander Staubo 16 Jun '99

16 Jun '99

I realize this is a completely silly and impossible question, but for a new Linux-based production server to run Zope, we feel a bit squeezed between using 1.10 (which does not have Z Classes), 1.11.0pr1 (which has proven to be quite stable but does not support concurrency), and 2.0.0a1 or the latest CVS version (which is an alpha, and which I have not attempted to run for stability testing). We'd be able to live with an unstable server for a couple (literally speaking, I think) of weeks, but beyond that time, we would like something of production, or at least beta, quality. Until this is cleared up we can cope with 1.110pr1, I guess. -- Alexander Staubo http://www.mop.no/~alex/ "`This must be Thursday,' said Arthur to himself, sinking low over his beer, `I never could get the hang of Thursdays.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_

RE: [Zope] external search engines (altavista, etc.)
by Alexander Staubo 16 Jun '99

16 Jun '99

Only in the sense that AltaVista and most other search engines uses the text and embedded meta-information on your pages for indexing. By meta-information I mean things like <meta name="keywords" content="sex drugs breast implants obscene nudity"> <meta name="description" content="This is my lovely home page"> and others. I believe some engines -- perhaps Northern Light -- use link relationships to attempt (and fail) at determining contextual relevance, but beyond that, the state of the search engine world has arguably not improved noticeably since a few years ago, bar small but welcome babysteps of progress like Ask Jeeves and Google!, imho. -- Alexander Staubo http://www.mop.no/~alex/ "`This must be Thursday,' said Arthur to himself, sinking low over his beer, `I never could get the hang of Thursdays.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_ >-----Original Message----- >From: ctpate(a)mail1.mco.bellsouth.net >[mailto:ctpate@mail1.mco.bellsouth.net]On Behalf Of Clarence T.

How? ZServer + PCGI
by Alex Rice 15 Jun '99

15 Jun '99

I have an existing pcgi setup and want to start using ZServer as well. I just don't how to get them both running. The Zope 2 INSTALL.txt says: * You can use PCGI and an existing web server if you use ZServer. How? Do you: python w_pcgi.py or wo_pcgi.py? start ZServer with what args? The docs are a bit confusing: wo_pcgi == without pcgi ==> ZServer and ODB3 w_pcgi == with pcgi ==> without ZServer (ODB2?) Therefore how to combine ZServer and PCGI? I know ZServer has a PCGI channel. Therefore maybe the above scripts should instead be named w_zserver and wo_zserver, because you can use pcgi in either case? As you can tell, I'm totally confused here. Would someone provide an example? Thanks, Alex Rice

Despite my love of Linux, there are "creature comforts" in MOSXS that simply aren't there on Linux yet. Like a decent diagramming program (Glyphix). Or a decent Entity-Relationship modeller (EOModeler). As that's what I'm doing for a good chunk of my day, MOSXS makes sense. Plus my coworker toasted her Blue & White G3 with a LinuxPPC 5 install and I'm waiting for her to fix it so I'm sure my install will work. :) > And ANYONE with knowledge of how Openstep framework packages should be > set up (when you don't have the luxery of making a Framework project in > ProjectBuilder) I'd be delighted to hear from. ObjectiveEverything > keeps its regular Python 1.4 libraries in such a Framework and I'd love > to hear how to keep the two both together and seperate. Some of the GnuStep people MUST know this. I do know that almost everything is really text-based (as is the Unix convention). I was able to successfully edit EOModeler models last year (after a few bad trials). Also, some of the key developers (like those at Omniweb) would know I'm sure. > And anyone who knows why I have common symbols that are not allowed with > MY_DYLIB output format, I'd also love to hear from. ;) Now that I don't know. _Deirdre Saoirse Systems Analyst Linuxcare dsaoirse(a)linuxcare.com, http://www.linuxcare.com/ 415 354-4878 x252 415 701-7457 fax Linuxcare.
