ZScheduler

There was some discussion earlier this year on the Zope-Dev list. THese items may belong in subclassed objects based on "schedulable"(?) or might be considered part of a larger "Zope Event Model" project, for later on. At any rate, here are some of the ideas that came out back in February. "Zope and a standalone Python event loop can easily pass messages in the form of records in a shared data store, e.g. a PostgreSQL database. > ... Do you think it's important to capture output? Not in itself, but it is certainly necessary to verify successful completion of each event, and those events can involve creation of output. ZODB may or may not be the target storage for such output, but an effective Event Manager must at least be able to confirm the output's existence and correctness, currency, etc. When an event fails an error event may be generated, whose first purpose is to attempt to restart the failed event, including verifying and/or reinitializing any prerequisites. An alert event (auto-page) may also be generated, to notify the designated driver of a mishap. (Yuck!) We found that we needed to track : dependencies (conditions required prior to start, such as prior events) normal runtime window (earliest start time, latest end time) normal runtime length (shortest expected completion period, longest) on-completion action (initiate subsequent event) on-error action (re-start event, alert event, etc.) >The kinds of scheduled tasks I'm thinking about are > - email reminders > - garbage collection > - updating syndicated content from other sites > >Anybody have other examples with other use patterns? - promoting new or updated content through develop, test, production status - spamming users when new content gets published - notifying content maintainers of irate feedback (after spamming users)" from: http://lists.zope.org/pipermail/zope-dev/2000-February/003220.html Later, Jerry S.

Newbie ZClass question
by Burchill, Scott B. 18 May '00

18 May '00

I'm running Zope 2.1.6 on Linux. I'm playing with both IE and Netscape, latest versions. I've just created my first Product/ZClass, Widget. When adding the ZClass I used CatalogAware and ObjectManager as base classes and had Zope create the constructor objects. I can now Add a Widget to a folder. Very cool. Here's my problem: I have now edited the Widget_addForm method and pressed the change button but I do not see the changes when I attempt to Add a new Widget to a folder. I have gone back to the method text and the changes I made are still there. I have turned off all caching in my browsers and hit the refresh button on every page I can think of. Here's my question: How dumb am I? Help! Scott B. Burchill \:)> /:(>

Zope 2.2.0a1 permission problems
by Cary O'Brien 18 May '00

18 May '00

I just installed release 2.2.0a1 on a glibc Linux box, but I keep getting a permission problem when accessing a database query. To be more specific... 1) Get zope 2.2.0a1 2) Unpack and install 3) Start - runs fine 4) Get ZPyGreSQL product 5) Unpack, build, install. No problems 5.1) create user in top level acl_users with manager role. 5.2) shutdown netscape, restart with new user login 6) Restart zope 7) Create a database connection to a local database 8) Try the test tab - works fine. 9) Using test, create a dummy table and insert 3 rows. 10) Test "select * from employees", works fine. 11) Create a zsql method to do the query, test it, works fine. 12) Create a Z search interface to run the query 13) access search interface -- works fine 14) submit - get unauthorized. The last line of the traceback is File /usr2/local/zope/Zope-2.2.0a1-src/lib/python/DocumentTemplate/DT_In.py, line 602, in renderwb (Object: all_employees) Unauthorized: 0 all_employees being my zsql method. And I thought I understood this stuff! Any ideas? -- cary

Re: [Zope] subfolder wrong absolute_url

In that case, you're right :-) However, any Zope object can potentially have sub-objects or attributes. As far as a browser is concerned, the any zope object can look like a folder at some point. Add acquisition into the mix, and you can make a URL to a valid object have other stuff on the end to an arbitrary length. Therefore, your suggestion above should apply to just about all URLs Zope receives. If Zope receives a request for "/spam/spam/foo" it should always issue a redirect (or whatever code it should be) to "/spam/spam/foo/" -- regardless of whether foo is of Folder type, ObjectManager type or DTML method type, or whatever. Are there any downsides to having this behaviour for all objects/all URLs? Or perhaps there could be some kind of per-path switch inside Zope that turns the redirect behaviour on or off. -- Steve Alexander Software Engineer Cat-Box limited

Re: [Zope] Newbie - problem connecting to MS Access DSN

The DSN is system. In fact the whole setup is *identical* to that on a colleague's machine I have spent the morning checking out. Which makes me think that the issue lies with my machine, and that it is an NT DAC / service pack interaction thing or somesuch. Dang. AndyG

SiteAccess problems in Zope 2.2.0a
by Alexander Limi 18 May '00

18 May '00

I have a small problem with the new Zope - URLs like: http://blah.com/__no_before_traverse__/ doesn't work anymore. Thus I can no longer access my root folder without it applying the rewriterule that is specified. Any way around this? Alexander.

First time using ZDiscussion
by Neil Burnett 18 May '00

18 May '00

Hi I have downloaded and installed ZDiscussion. Can anyone direct me to some instruction on how it is used? I have checked the read meees of all the products, but they don't give a usage overview. I have also searched www.zope.org for ZDiscussion and only found the download link. I think that product is a set of classes which expect a user interface to be developed by me. Is that right? Thanks in advance Neil
