Manipulating dates
by Corey Ralph 09 Jun '99

09 Jun '99

This is probably more of a MySQL question than a zope question, but I figured someone here would have dealt with it before. A couple things I need to do with dates, I'm not sure what the best approach would be: 1. Convert dates to/from mysql (yyyy-mm-dd) to normal format (dd/mm/yyyy) 2. Subtract dates to get the interval in hh:mm:ss format. I have done this in mysql by converting them to timestamps, then subtracting one from the other, then converting this to a time: select SEC_TO_TIME(UNIX_TIMESTAMP(EndTime)-UNIX_TIMESTAMP(StartTime)) ... Except once I put this function into a Z SQL Method, it doesn't work. Surely there is a better way anyway. Would I be better off doing them in DTML or in the SQL? Any ideas appreciated. Cheers, Corey

Q. on slashdot.py
by zhaoway 09 Jun '99

09 Jun '99

Hi, Zopers, I'm playing Zope with a dialin-line at home. I use slashdot.py in /index_html. It works well. But one thing is that I want that everytime I dial-up to go online, it can update (semi-)automatically the headlines locally. Now, I've to go into /manage, fill in my username:passwd, click on this External Method then click on Try it! then go back to /index_html to see the updates it has made. I've also tried add the Try it! URL(/slashdot_id) into somewhere in /index_html then when go online, I just click once hope it will update, but it does not update. Any easy hacks on this? I'm using win32. --zhaoway P.S. Why I want to do this because http://slashdot.org/ultramode.txt is ultra fast. :) I go online far less than once/hr. Guess what? I want somedays later I could do email in Zope with my browsers instead of using any specific Email client. :) Just like move the hotmail frontend home, no real SMTP server or POP3 server, just perform normal email client tasks. Thrlling! :) I'm really fascinated by Zope's manage interface.

Re: [Zope] Newbie: install a Product

>I think what you want to be doing is going to the folder you wish to add >an instance of the product in, and trying to add it there. That is, go >to the URL http://localhost:9673/manage, select your product from the >drop-down, and click add. I just cannot see my product(Poll) in the drop down. There's no changes there. Now I've just checked Control-Panel, it says "Broker Product Poll". When I click on add (Principia Factory), it says: "Before you can define a factory, you have to define one or more 'methods', such as Document or other objects that do the factory's work." I'll see through the tutorial soon, but if you could give a quick hack letting me do the install, it will be great! :) Thank you! :) --zhaoway

What's the best way to format token type properties? The best I can do with my limited grokitude of dtml is this:    This outputs like this ['Ambient', 'Drone Rock', 'Beats'] How do I convert sequence-item to a plain string so I can bullet it or whatever?

Thanks!

Hi all, Thanks for visiting the site. Hope all enjoyed it. Thanks also for giving me feedback of several problems. I've fixed some javascript thingies and a bad url. Also added a 'how_should_webpage_normally_look' however, on solaris and hp-ux systems the submenus are cut-off :-(. Does somebody knows about the coördinate system on these systems with netscape? I think that's the problem there. But maybe the problem is solved now??? So, if somebody has still some time and experienced at an earlier visit some problems, please check it once more. Offcourse you can visit the site also just for reading some stuff :-). www.master.cit.be/c8/default.html Tom.

Loading the same Product set with ZODB2 works just great. I'll look into this, Zope 2.0 should be at least code b/w compatable with 1.10.2 products. -Michel > Any ideas? > > Michael Bernstein. > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

Newbie: install a Product
by zhaoway 08 Jun '99

08 Jun '99

This is a pretty newbie's Q: Before I read through the ProductTutorial stuff, I just wanna install the Poll product and/or the Guestbook product to have some fun. After I untar'ed the package into place, and did a Add-Product under the Control_Panel -> Products, I got the open- box-icon-Poll stuff under Control_Panel -> Products -> Poll, then I saw: "There are currently no items in Poll Product", now what? I have not got any change in the Add-list anywhere. And Add-Factory did not wanna work here. Please gimme a step-by-step. TIA. :) I just wanna have some first hand experience on successfully installing a product before I read through the whole tutorial. Think this way I'll gain some much more fun, seems not, hehe.... --zhaoway .________________________________ /http://mud.jlonline.com/~zhaoway\ 闷罐船 \zhaoway(a)public1.ptt.js.cn / 水世界 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

apache + ZServer + Zope 1.x
by Alex Rice 08 Jun '99

08 Jun '99

Does there is exist a tutorial, or can someone provide a brief explanation of how to use ZServer in combination with Apache + Zope 1.10.2 src release? I'm currently running Apache -> PCGI Zope, but don't want to wait for the 2.0 for FTP and WebDAV support <drool> Thanks , Alex Rice | alrice(a)swcp.com | http://www.swcp.com/~alrice Current Location: N.

I've come upon a snag however. If I pass in SomeObject above I will get an "You are not authorized to access SomeObject" error. So instead I need to pass in the object id and get the object myself. However I have had no luck working out how to do this. What I need is the getitem method in an external method. Searching through all the code as left me none the wiser. Here's the closest I have. from AccessControl.Permission import Permission def hasPermission(self, pname, objName, AUTHENTICATED_USER): SomeObject = self.__getitem__(objName) P = Permission(pname,'',SomeObject) P.obj=SomeObject for i in AUTHENTICATED_USER.getRoles(): if i in P.getRoles(): return 1

I just wanted to let you know that I've added a new animated GIF to the Portal Toolkit Demo. http://www.zope.org/Products/PortalToolkit/Tour/CollaborationAndTheDeskt op The new animated GIF shows off Zope's WebDAV and FTP integration. If you've never personally experienced the magic of using WebDAV or FTP to edit your Zope objects, be sure to check this out and start salivating. -Amos P.S. I can't wait for some more cool WebDAV clients! -- Amos Latteier mailto:amos@digicool.com Digital Creations http://www.digicool.com
