Everitt's suggestion is good, but I suspect that you will probably have to write an External Method to automatically create and enter the session... Go to lib/python/Products/OFSP/Session.py and browse the source for the functions and their parameters. In particular, on the Folder object you have created you need to execute .manage_addSession, then For example, if I was in the parent folder which will contain your newly created Folder, my DTML might call:  where 'folder' is obtained from a form, and PARENTS[0] is the form-response's immediate parent (i.e. the containing folder), and newSession is an External Method something like this: def newSession(parent,foldername): parent.manage_addFolder(foldername) current=getattr(parent,foldername) #now current is 'inside' the new folder current.manage_addSession('session_id','ActiveSession') current=getattr(current,'session_id') current.enter() return 'some DTML snippet' Note: This is untested code! > ---------- > From: Max Murdock[SMTP:ffelici@gol.grosseto.it] > Sent: Thursday, February 25, 1999 4:32 AM > To: zope(a)zope.org > Subject: [Zope] [Q] About sessions and Zope > > Zope is surely a great system to develop dynamic html sites, and even > a > novice like me can learn how to use it. > > My problem is that I've got to be able to make users able to manage > sessions in a transparent way: people who get in the site should open > a > session, create a folder, put there their material and leave to tehe > site > manager the task to verify what they sent and close the session. > And all this should be done seamlessly by the user, possibly with a > single > form, without having the task to "click to add session", the enter the > name, then go to the session and make ti active, create the folder and > upload there the files... > The main.dtml suggests me to present the user a form with the > "manage_addSessionForm" button to press... then he can put the session > name > and click "add".

For what it's worth, we're working on weaving the capability deeply into Zope. That is, having roles of users whose changes must be reviewed before they are live or go into the site-wide catalog/index. We've done several rough versions of this for customers and for demos. Making it a general facility takes some thinking though. Also, you have to give the reviewers a productive interface for looking at a large amount of data quite quickly. I'm not completely convinced that we can come up with a single, general-purpose, works-with-all-objects facility for reviewing. If we can, though, it will pretty radically change website development, as it will apply to all content (calendar entries, HTML files, package uploads, used car listings, etc.) For now, your approach was a pretty good one. Take the people to a "login" page that automatically puts them in a session and perhaps authenticates them with the cookie-authentication from UserDB. --Paul

Re: [Zope] Splitting the Zope mailling

You have a good point, I belong to another list, PHP3, where the same discussion has been raging for months. The basic feeling there is that if the list was split, the 'experts' would leave thereby the questions on the list would be answered by 'less well informed humans' :). This would then 'force' the 'mere mortals' on the original list to migrate. Thereby creating the problem all over again. The PHP3 list btw has about double the traffic of this list. Recently, the list came up with a very simple method to make the list easier to digest. All posts should have a 'topic indicator', for example, all posts about installing should be marked as [INSTALL]. All development posts marked as [DEVEL] and etc. Seems to be working a treat. my 2c See ya Phil ----- Original Message ----- From: Martijn Faassen <faassen(a)vet.uu.nl> Cc: <zope(a)zope.org> Sent: Thursday, February 25, 1999 9:19 AM Subject: Re: [Zope] Splitting the Zope mailling >Ken Manheimer wrote: >[snip] >> zope(a)zope.org zope-dev(a)zope.org >> ------------- ----------------- >> installation and operation dtml coding questions and hints >> content management using the programmer APIs >> desired user-level features new and existing architecture design >> business decisions contributed widgets >> w.r.t. open source >> public relations in general >> >> These are off the top of my head - and i'm relatively new to the >> community, so i'm quite open to suggestions about what belongs where. >> Overall question is, does the split make sense in principle? > >I'm not against this split.

[Q] About sessions and Zope
by Max Murdock 25 Feb '99

25 Feb '99

Zope is surely a great system to develop dynamic html sites, and even a novice like me can learn how to use it. My problem is that I've got to be able to make users able to manage sessions in a transparent way: people who get in the site should open a session, create a folder, put there their material and leave to tehe site manager the task to verify what they sent and close the session. And all this should be done seamlessly by the user, possibly with a single form, without having the task to "click to add session", the enter the name, then go to the session and make ti active, create the folder and upload there the files... The main.dtml suggests me to present the user a form with the "manage_addSessionForm" button to press... then he can put the session name and click "add". So he automatically returns to the folder view, and that's not exacltly what "transparent to the user" means, understand me... So I guess I have to reprogram the routine that makes the form: instead of showing the folder it should automatically start the session and ask for a new folder to be created. The PROBLEM: where's that routine? Where's the script that makes the form? Where is it going when I select the "manage_addSessionForm" action? I ain't been able to find it, even with the "find" command, ain't got other ideas... I understand maybe this Q requires a bit of answer... if anyone wont' take this labour I can perfectly understand; otherwise: can someone point me a doc explaining all this? I've downloaded most of the docs in the Zope site, and I can dnload more... TIA! Max Murdock

Re: [Zope] PostgreSQL DA Release Version 0.2
by Oleg Broytmann 25 Feb '99

25 Feb '99

Hi! After adding Database Connection to my folder I found that every time I started Zope the connection opened, so postgres forked. I cannot close the connection - even when I press "Close Database Connection" postmaster stays forked. Only when I shut Zope down postmaster close connection. I am pretty sure it is problem. What if posgres died while Zope is active? Will ZPygresDA restore connection? Who is responsible for the problem - Zope or Adapter? Can I setup a timeout, after which (if there is no activity) Adapter closes connection automatically and restores connection on next access? Oleg. ---- Oleg Broytmann http://members.xoom.com/phd2/ phd2(a)earthling.net Programmers don't die, they just GOSUB without RETURN.

Backing up Zope's database?
by Martijn Faassen 25 Feb '99

25 Feb '99

Hi there, We're running Zope on an NT server here and the backup system (Arcserve) apparently gives an error when it tries to backup Zope's 'var' directory. I would like to have this succeed (and end up with a non corrupted database, of course :), so here are some questions: * is this perhaps fixed by Zope 1.10? I read something about Zope 1.9 not doing proper file locking on NT yet, so there is some difference here. * Is copying a database while Zope is running a good strategy? (probably not) * What other options are there? For instance, NT seems to be able to copy the var dir just fine, so perhaps a copy could be made that Arcserve could backup. Still, that database would be backuped while Zope is running, so perhaps this isn't a good idea. Thanks in advance, Martijn

I GOZ, I have a problem with the float method from DateTime module !! It seems that Linux and WIN32 platform(NT) do not give the same result. Is there an explanation?

RE: [Zope] Preserving Settings during a user's session
by Jeff Nielsen 25 Feb '99

25 Feb '99

Wow! Thanks for all the replies to my query about preserving session variables. I rather like Christopher's idea about using a single SessionID variable. Most of the data in my application is in a database (SQL Server) and I could create a Session table with a sequential ID that would hold the values I want. I think I'll stick with the simple method, using the format www.server.com/zope/page_name?SessionID=1234. I'm still rather a Zope novice and my immediate priority is to get my web site up and running instead of becoming a Zope master... I'm using Zope with IIS and it does provide session tracking with a unique ID, but it requires the use of short-term cookies. I could pass the session ID from IIS to Zope (I think), but that violates my no-cookie goal. Similar to what someone mentioned somewhere in the thread, my goal is to keep the client side as simple as possible in order to minimize end-user issues. I prefer to do all the complicated processing on the server, which is completely under my control... Again, thanks for all the response. Jeff jeffniel(a)ix.netcom.com

Proposal: Public read access to Zope CVS
by Ken Manheimer 25 Feb '99

25 Feb '99

I've put together a proposal for an arrangement that would make the digicool CVS repositories (and other peoples Zope-related repositories, if they care to participate) available for read across the internet. Please take a look at it, let me know if you have any suggestions, concerns, interest in participating, etc. Ken Manheimer klm(a)digicool.com

count- of-by-one?
by ron＠rotflol.cx 24 Feb '99

24 Feb '99

count- (statistic-name) seems to be of-by-one. [select_systems is a ZSQL Method]    This should return 41 [counting the rows displayed when a normal report is displayed]. It however returns 40. BTW, is this the most efficient way to get the number of rows returned by a query? -- <- Ronald Offerman | ron(a)offerman.cx <- Root Powered Carrot Munchers Ltd. Inc. SA AG BV "This is Linux Country.
