INSTANCE_HOME breaks cross products import
by Johan Carlsson 18 Oct '00

18 Oct '00

Hi, I'm using then the INSTANCE_HOME to have separate Zope instances use a base zope installation and a shared products directory with symlink's to the instance product folder. As described in the "How-To: Make your life easier with INSTANCE_HOME" by 4am. Now the LoginManager can't import anything from the ZPattern module. <start up error message> 2000-10-17T21:59:14 ERROR(200) Zope Couldn't import Products.LoginManager Traceback (innermost last): File /bigshare/zopeservers/Zope-2.2.2-base/lib/python/OFS/Application.py, line 397, in import_products (Object: string) File /bigshare/zopeservers/unitedrings/Products/LoginManager/__init__.py, line 1, in ? File /bigshare/zopeservers/unitedrings/Products/LoginManager/LoginManager.py, line 9, in ? ImportError: cannot import name SheetProviderContainer </start up error message> Now this works fine if I start Zope from the base Zope installation. So what goes wrong and why? Does I do anything wrong or should/could this be fixed in the product? If so I guess it would be practical to document som product author guidelines. Regards, Johan Carlsson

Re: [Zope] Want to access ZClass Instance from external program

Well, I've gotten xmlprclib and fixed it up so I can talk to my server. So far I can retrieve objectIds and retrieve objects via an objectid, but I can't figure out how to get to the property sheets. Here's what I've got: server = Server( "http://jonprettyman.com" ) print server for k,v in server.EBQ.id_company_apply_html.propertysheets.common.propertyItems(): print "%-15s: %s" % (k, v) My ZClass has a propertysheet named ``common'' The error I get is: -2 Unexpected Zope Error Value and a bunch of HTML which boils down to: Resource not found -jon Kapil Thangavelu <kthangavelu(a)earthlink.net> writes: > its easiest to it with (IMO) > > xml-rpc > > and find your zclasses with calls to objectids and query the > propertysheets directly for property info. > > > check out > > http://www.zope.org/Members/Amos/xmlrpclib.py > you'll need to fix a base class and an import. > > www.xml-rpc.com > > www.xml.com search for amos > > and zope.org for howtos on xmlrpc > > Cheers > > Kapil > > _______________________________________________ > 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 )

RE: [Zope] MySQL and Zope struggles

Or you could renormalize your data to have: --------- ----------- | Artist | | Note | |---------|-------|-----------| | id | | id | --------- | artist_id | | note_str | ----------- you now have a list of notes by artist_id. You typically won't have a screen that doesn't have an Artist context to be adding a note to. (or to remove all notes from). Of course this means more work to migrate :-( And I don't know all possible scenarios for which you would need the structure you gave, but it is another way around this. It probably doesn't solve real complex scenarios either.

bobobase_modification_time and .zexp
by Wolfgang Strobl 18 Oct '00

18 Oct '00

import/export obviously doesn't preserve time stamps (i.e. bobobase_modification_time). This is unfortunate for any content which depends on those timestamps. How do you people out there solve this problem when it comes to moving content from different Zope installations into a single one?

status of SOAP for Zope?
by Brad Clements 18 Oct '00

18 Oct '00

MS has released ROPE for client-side SOAP development (finally). I can't seem to find anything in Zope for doing SOAP, but it was announced in Dec 1999 as "upcoming". What is the status of SOAP on Zope, I need to know if I can use ROPE..

strange <dtml-sendmail> problem
by Erik Myllymaki 17 Oct '00

17 Oct '00

This is a DTML_Method I call from my standard_error_message: <dtml-sendmail mailhost="MailHost"> To: Webmaster <<dtml-var webstaff>> From: ZopeServer <<dtml-var zopeserveraddress>> Subject: Problem at <dtml-var URL> Error Type: <dtml-var error_type> Error Value: <dtml-var error_value> Error Msg: <dtml-var error_message> <dtml-in "REQUEST.items()"> <dtml-var sequence-key>: <dtml-var sequence-item> </dtml-in> </dtml-sendmail> I call it like this: <dtml-var send_errors> The mail is sent appropriately including all the REQUEST items, but the page that is calling this DTML_Method never finishes downloading. It seems that the loop through the REQUEST items causes page rendering to hang? After several minutes, stopping the page download brings up a *transfer interupted* message and only then do I see the bottom of the page. If I leave this out: <dtml-in "REQUEST.items()"> <dtml-var sequence-key>: <dtml-var sequence-item> </dtml-in> ...it works well. Thanks for you help. -- Erik Myllymaki erik(a)pacific-shores.com

GUF and IE friendly error messages
by Paulo Eduardo Neves 17 Oct '00

17 Oct '00

Hi, I'm using General User Folder (GUF) in cookie mode for the login in my site. When someone doesn't have the appropriate permission to access a resource, GUF should show the Login screen. It works fine, except for some people (not all) that uses Internet Explorer 5. They see IE http user friendly error page. If the user is told to change the IE configuration for not showing friendly errors, the login screen appears. It is not easy to setup for unexperienced users. When the http status is 400 (not found) IE shows the friendly error just for pages smaller than 512 bytes. Unfortunately, it doesn't work when the error status is 500 (server error). I've tried to change http status with RESPONSE.setStatus(200) in the standard_html_error, but it doesn't work. Is it possible to change the http status after an exception is raised? Can someone suggest a solution or workaround for this problem? Thanks in advance for any help, -- Paulo Eduardo Neves http://www.samba-choro.com.br
