Hello Looking for zope calendar advice and ideas.. Design goal: A Zope smart-calendar product which allows very interactive setting and display of calendars in a range of formats. Features: - version 1: HTML only - version 2: FLASH [ready to pass values to and from flash interface] - XML formatting of user_calendars #allow structured loading and saving of user calendar data - XMLRPC methods to allow group calendars to talk to each other and have an 'invisible' toggle. - Allow user permissions to modify what is shown, how it appears etc - Users can select a range of days and then assign forms, URLs, images, text - methods include: 'on_select', 'on-click',..'link to selected', 'link_to_first', 'e-mail_selection', etc . As an example, see the excellent Sheridan Calendar Widgets ActiveX components http://www.sheridan.com feature a trio of day, week, month, year controls and properties which allow wide variation in the style and presentation of these. Fast and pretty easy to use. If anyone has seen any good-looking and good-running calendars in HTML, Java, Zope, ???, then please let me know. I have played with Behive's Calendar product and it may be a matter of extending that, but I would love to hear of other work planned or ongoing, plus any ideas you may have about the requirements/interest for implementing such a creature. Ideally we would like to have rapid highly object-oriented methods to restyle or rescale the calendar rapidly through DTML.Python methods: Some wishful examples: <dtml-var calendar_Make_thumbnail(64,64, expanded = [320,240])> # when clicked on it expands from 64x64 to 320x240 size <dtml-var calendar_scale(216, 240) <dtml-var calendar_expand_to_fit_frame> <dtml-var calendar_style(footer_style, default='house_style')> <dtml-var calendar_SetImage(selected_dates, 'lovelyimage.jpg')> - Jason ________________________________________________ Jason CUNLIFFE = Nomadics.Studio(DesignDirector) Smart_Map_Systems[design.technology.application] <jasonic(a)nomadicsltd.com> tel:+33 4 94.76.98.72

Formatted date anomaly ...
by Darran Edmundson 07 Feb '00

07 Feb '00

Here's a strange one. I have a property StartDate (type date) set to "01/01/2000". Can someone please explain why the DTML snippet: <dtml-var StartDate> <dtml-var StartDate fmt="%Y"> renders as: 2000/01/01 1999 (More info on Zope formatting of dates and times can be found in the HowTo: http://www.zope.org/Members/AlexR/CustomDateFormats) Cheers, Darran.

Data.fs corrupted.
by Jay, Dylan 07 Feb '00

07 Feb '00

When I try to start up my zserver I get the following Traceback (innermost last): File "D:\Program Files\Zope2\z2.py", line 449, in ? exec "import "+MODULE in {} File "<string>", line 1, in ? File "D:\PROGRA~1\Zope2\lib\python\Zope\__init__.py", line 109, in ? DB=ZODB.FileStorage.FileStorage(Globals.BobobaseName) File "D:\PROGRA~1\Zope2\lib\python\ZODB\FileStorage.py", line 301, in __init__ self._pos, self._oid, tid = read_index( File "D:\PROGRA~1\Zope2\lib\python\ZODB\FileStorage.py", line 1298, in read_in dex panic('%s has invalid transaction header at %s', name, pos) File "D:\PROGRA~1\Zope2\lib\python\ZODB\FileStorage.py", line 218, in panic raise CorruptedTransactionError, message ZODB.FileStorage.CorruptedTransactionError: D:\Program Files\Zope2/var/Data.fs h as invalid transaction header at 40013720 I believe the corruption occured because I was uploading data into Zope when my diskspace ran out. I don't have a backup. How can I back out the offending transaction or generally fix my Data.fs?

Zope Database Size
by James W. Howe 07 Feb '00

07 Feb '00

At what point does it make sense to store data outside of the ZODB? For example, I have a site which wants to have access to a news article archive. If the articles were stored in Zope, the ZCatalog searching would make this task almost trivial. I'm concerned about the size of the database, however. The archives may go back several years and represent information from a weekly news publication. I have a sample archive of one "issue" which constitutes about 130k of raw text (no graphics at this point). I expect that a typical "issue" may be around 130k - 200k. If I store that information in Zope, probably as instances of a ZClass with properties to hold some information and perhaps DTMLMethods to hold the many article content, how many weeks of archive information could I reasonably store in Zope before the thing would become too big? This archive solution is likely to be replaced in the future so I'm interested in finding a solution which is simple and quick to implement but will provide adequate performance for my users. Any info on this subject would be appreciated. Thanks. James W. Howe mailto:jwh@allencreek.com Allen Creek Software, Inc. pgpkey: http://ic.net/~jwh/pgpkey.html Ann Arbor, MI 48103

Difference between manage_addProperty on a DTMLDocument and on a Folder ? Folder ?
by Benillouche, Michael 07 Feb '00

07 Feb '00

I have the following problem : When I execute this code : <dtml-call "REQUEST.set('compteur_login', _.str(compteur) )"> <dtml-call "manage_addFolder(id=compteur_login)"> <dtml-call "_[compteur_login].manage_addProperty('type', 'FC', 'string')"> The Folder is created with the property 'type' But when I execute this code : <dtml-call "REQUEST.set('compteur_login', _.str(compteur) )"> <dtml-call "manage_addDTMLDocument(id=compteur_login)"> <dtml-call "_[compteur_login].manage_addProperty('type', 'FC', 'string')"> I have the following error : Error Type: AttributeError Error Value: 'string' object has no attribute 'manage_addProperty' It seems that manage_addProperty doesn't behave the same way on a Folder and a DTMLDocument . Any solution to make it work ? Thanks a lot. Michael

Access Violation for an NT Service
by Stephen Pitts 07 Feb '00

07 Feb '00

Hi! I have deployed Zope 2.1.3 (with a home-compiled version of PIL) on Windows NT 4.0 Advanced Server. It runs fine from start.bat, but when I try to start the service, I get an access violation from PythonService.exe. For some odd reason, Dr. Watson reports that the access violation comes from "pythonservice.e.exe". Perhaps that could be related to the problem? Does anyone have any idea what the problem could be? -- Stephen Pitts smpitts(a)midsouth.rr.com webmaster - http://www.mschess.org

ZCatalog TextIndex
by Terry Kerr 07 Feb '00

07 Feb '00

Hi, I have setup a TextIndex on the description attribute, but I cannot find any objects when searching. This is the syntax I am using: <dtml-in "Catalog(description='blah')"> I know that atleast one of my ZCatalog aware instances has a description attribute='blah'. If I change the index to a FieldIndex, I can search for description='blah' and find the object! What am I doing wrong. Does TextIndex have a bug? terry -- Terry Kerr (terry(a)adroitnet.com.au) Adroit Internet Solutions Pty Ltd (www.adroitnet.com.au) (03) 9888 8522 0414 938 124

Patch for Custom upload hook.
by Jay, Dylan 07 Feb '00

07 Feb '00

When using webdav and other upload techniques it is not possible to customize what object a file is uploaded as. This patch will determine if a hook function named ManageUploadHook is present in the aquisistion path and if it is, use it to handle the file creation process. If it returns 1 the file was created, else the normal process is followed. In file webdav/NullResource.py, line 143 parent = self.__parent__ try: hashook = parent.this().ManageUploadHook except: hashook = 0 if hashook and parent.this().ManageUploadHook(name,type,body): blah = 'blah' elif type in ('text/html', 'text/xml', 'text/plain'): self.__parent__.manage_addDTMLDocument(name, '', body) This works nicely with a python function such as this if type[:6]=='image/': self.manage_addProduct['Photo'].manage_addPhoto(self.this(),name, file, content_type=type) return 1 else: return 0

Re: Please share answers here

> ps: please answer via private mail, i cant follow the list because the > disk of the mailserver im using is full since 2 days :( Those of you with answers to these questions, PLEASE don't only answer them in private email, even if that's what the questioner thinks they want. We are all reading the Q&A and learning, so please at least Cc to the list. In the case of the questions from bertl, the answers look like they'd be extremely useful, so it's quite annoying to wonder whether we'll ever see them.
