Zope
by Joerg Wittenberger 28 Sep '99

What's the difference? I have a task list, which adds a new task with the following simple dtml method. The first version gave me some grief, because it happend to work as superuser, but no longer when I logged into zope as manager of the page (which is restricted to the manager of the task list). Code working as superuser only: <dtml-call "REQUEST.set('id', _.str(_.int(ZopeTime())))"> <dtml-with "manage_clone(task, REQUEST['id'], REQUEST)"> <dtml-call "propertysheets.manage_changeProperties(REQUEST)"> <dtml-call "propertysheets.Basic.manage_changeProperties(REQUEST)"> </dtml-with> <dtml-call "RESPONSE.redirect(URL1 + '/listall')"> To work out what's goin on I removed those calls to propertysheets and threw in all sorts like <dtml-var id>. I allways ended up with a permission problem (zopes reply said), but I doubt. Now I modified the code slightly... Code working as Manager as well: <dtml-call "REQUEST.set('id', _.str(_.int(ZopeTime())))"> <dtml-call "manage_clone(task, REQUEST['id'], REQUEST)"> <dtml-with "_.getitem(REQUEST['id'], 0)"> <dtml-call "propertysheets.manage_changeProperties(REQUEST)"> <dtml-call "propertysheets.Basic.manage_changeProperties(REQUEST)"> </dtml-with> <dtml-call "RESPONSE.redirect(URL1 + '/listall')"> What's the difference (besides that faliure within the dtml-with won't remove the cloned object anymore)? Thanks a lot. /Jerry -- You can have it done fast, you can have it done cheap, and you can have it done well. --- But you can only have two of those at once.

catalog indexing
by Jason Spisak 28 Sep '99

28 Sep '99

Does anyone know how to make the catalog index the string 'C++' I would be greatly indebted. Or just as good, when will the catalog allow specific phrases to be indexed? Obviously 'C++' is not in the list of stop words, so I guess it sees the '+' and ignores it. All my best, -- Jason Spisak webmaster(a)hiretechs.com

Oracle and MAX
by Dan Rusch 28 Sep '99

28 Sep '99

Has anyone used the sql MAX() with Oracle. We were using Sybase and ported to Oracle and it seems that the MAX() in Oracle converts my real numbers to integers this did not happen in Sybase, any thoughts? By the way AVG() does the same SELECT MAX("ItemNumber") FROM SO_Items WHERE "ServiceOrderID" = 1 AND "ItemNumber" < 2 The ItemNumber is a number(9,3) in the table SO_Items. By the way the sql code works fine in sqlplus.

by Victor Zhai 28 Sep '99

Hello: all Can Zclass provider some method of it's own.Just like Products Whick is more easy to operate ,Zsql or Zclass. if so,Please give me some advice about that. More,Please give me some document about ZODB,and ZClass examples. Thank a lot.

ZODB and # of objects
by Andrew M. Kuchling 27 Sep '99

27 Sep '99

FileStorage's property of requiring memory proportional to the number of objects in the ZODB may be causing me problems. I'm running into trouble with a ceiling of 150,000 items, but the memory usage becomes too high, 60 or 70 or 80Mb well before reaching that point. I don't think the problem is a memory leak in my code, but perhaps I'm doing something wrong; has anyone stored that many items in a ZODB before? What was the memory usage like? (The largest number of objects stored in a Zope database would be an interesting bit of trivia.) -- A.M. Kuchling http://starship.python.net/crew/amk/ And forewarned is seldom forearmed.

But after reading the ZODB features, I am trying to see whether or not ZODB is suitable for my project. If it is suitable, I might as well take the advantage of it & save me some works from messing with RDBM. Regards, Ping __________________________________________________ Do You Yahoo!?

Barriers to Zope popularity: Part 1: wysiwig editing
by Jay, Dylan 27 Sep '99

27 Sep '99

Having been using Zope for the past 8months or so I see two potential reasons as to why more people at my work havn't taken to Zope. One discussed of late is WYSIWYG editing. I HATE wysiwyg editing. It invariably makes a mess. It seems that a lot of people disagree with me and find a system that allows wysiwyg editing to make the creation of good web pages simplier. Possible solution: Frontpage seems to me to be the weapon of choice for these "amateur" web authors. I imagine that frontpage will support webdav in the future but for now I think it would be possible to support a subset of the frontpage web extensions. At least the ones that deal with authoring etc. It all uses HTTP so I imagine it would be as hard to implement as webdav support was. Products could even be created for searching and web discussion extensions but I would think that this would detract from Zope and add support for frontpage more than the reverse. The next problem with this is how to edit partial pages in a wysiwyg editor. Ie how to edit a whole page when every DTML doc has <dtml-var standard_html_header> etc in. What we could do is to have a special render method that produces an html document which has all the html the real rendered page does as well as the DTML cunningly encoded in it. Then a special update method can take this an process the changes to the parts of the document as neccesary. For instance  <h2></h2> <p> This is the  Document. </p>  could be rendered as  <html> <head> <body>  <h2>My Documents Title</h2> <p> This is the myDoc Document. </p>  </body>  or something similar. As long as ALL the dtml in a document can be encoded in this way and the visual editor leaves the comments alone then this will work. This leads to the question of how the update method will deal with updates to include documents/methods/properties? Not sure. It could either, give an exception (might be possible with WEC), just ignore them, or try and perform the updates on the other objects (potentially messy but possible in limited cases???). Thoughts?

RE: [Zope-dev] Re: Transaction support on MySQL

Thanks Rik, for removing the cross post on this thread. It's pretty tiring to read the same thread of discussion twice, especially since I try to read every message that goes by. The original poster was probably looking for the broadest possible audience to answer his/her question. When you folks see a coss-post to zope-dev, think for a second before automaticly replying to 'all recipients'. If you think the discussion should really go two ways, then the cross-post is ok. If it's going for broad audience, take it over to the big list. if it's a development question, take it off the big list and keep it on zope-dev.
