Zclass question
by Joshua Brauer 10 May '00

10 May '00

Probably a stupid question but I'm banging my head against a wall this afternoon.... I'm setting up a directory product... Consists of two Zclasses Directory and People. Both inherit ZObject Manager ... People is inside Directory and there will be many instances of People in each instance of Directory... However, when create an instance of Directory there is no Pople in the Available Objects list to add.... I know it works because I've done it before, but I can't recall if there are any gotchas that I've forgotten?

Re: [Zope] Apache ProxyPass and ZServer

>I haven't found anything in the HowTo that says how one would deal >with SSL so I _guess_ it's not possible. Is that true? > >--Ragnar Actually it _is_ possible. But only (well, to me at least) to some degree. And a bit of hacker' attitude (should we rather call it zen?) ,-) I use Apache+mod_ssl on linux. First, download the siteaccess product. Then add a dtml method to the root folder and then set it up as an access rule. I use the following setup <dtml-call "REQUEST.set('SiteRootPATH', '/')"> <dtml-if "1+(_.string.find(PATH_INFO, 'manage'))"> <dtml-let HOSTNAME="_.string.replace(HOSTNAME, 'http://','https://')"> <dtml-call "REQUEST.set('SiteRootBASE', HOSTNAME)"> </dtml-let> <dtml-else> <dtml-call "REQUEST.set('SiteRootBASE', HOSTNAME)"> </dtml-if> <dtml-call "REQUEST.setURL(base=SiteRootBASE, path=SiteRootPATH)"> It's rude, and by far not the best solution, but it works. The variable HOSTNAME allows you to do virtualhosting and to set the base url on a per folder basis. e.g. you set the property on 'myfolder' to http://mysite.com. This way, you could add (from the ground up) ssl-ed sites as well, just modify the above method to check if HOSTNAME has https in it. As You see, I primarily added the above to be able to securely administer a site (and to do virtualhosting). However, there still is a problem: you have to call the /managed URL with the https:// perfix, otherwise your password goes to the server UNencrypted. The interface actually gets encrypted. So, if zope sees an url with /manage at the end, it should redirect you to the same url but with a https:// prefix. Any ideas, zope gurus? Have a nice day Ambrose

RE: [Zope] Images & Zope, Please help!
by Stuart Foster 10 May '00

10 May '00

What I am doing is using the LocalFS product. This will let you point to a directory on your server and access it as if it were a Zope object. Then in Zope you can say <img src="images/banner.jpg> and it will use the images in the directory instead of the DB. Also I have recently implemented a site using ZServer and Apache. -----Original Message----- From: W O'Neil [mailto:bill@igic.com] Sent: Wednesday, May 10, 2000 11:29 AM To: zope(a)zope.org Subject: [Zope] Images & Zope, Please help! Hello! New to zope and I'm looking for some practical advice on how to handle image heavy portions of a zope site. I have looked through the HOWTOs and read some comments about creating 'pseudo' images or zope pointers to static image urls and using those rather than storing all images in the DB. This seemed intriguing but I was looking for some practical experience/advice. Still I'm working on a moderate traffic site on a relatively low powered server (you take what you can get) and I'm concerned about always serving images out of the ZODB. As far as 'pseudo' images go, storing these pointer IMG tags rather than the images sacrifices some flexibility of setting ALT/WIDTH/HEIGHT tags AND then requires a server redirect as zope is currently set up as the apache webserver default, with anything coming to http://sitename/static/ going to the ws root. This seems somewhat clunky. I suppose I could 'hardcode' the static image tags in document header/footers but this still encounters the redirect. Anyone have any hard, real experience? Stories? Advice? Is this a valid concern or am I making too much of it? Should I just store the images in the DB? I have no problem storing banners and such in the DB its the site template graphics that I'm talking about here. Please let me know of your experiences of any articles/archives I may be missing on this subject.

SIGSEV when trying to import ExtensionClass
by Fredrik Aronsson 10 May '00

10 May '00

Hello! I have a problem with ExtensionClass, it can't be imported when running from the webserver. From the command line it works excellent. I have put information at http://www.dtek.chalmers.se/~d98aron/pcgi.html if someome has time to look at it. ExtensionClass is needed to run Zope, which must be started through pcgi at our server for security reasons. Thanx! Fredrik Aronsson (PS mail me if you want more information)

User is logged in? (LoginManager)
by Jon Delheimer 10 May '00

10 May '00

How do you determine if the user is logged in? You can not check for "Anonymous User" because the user can briefly be "LoggingInUser". You can not check for the Anonymous role because LoginManager forces everybody to have the Anonymous role. I think if LoginManager gave LoggingInUser the Anonymous role and stopped forcing everybody else to have the Anonymous role, I could use the Anonymous role for the test. Is there another way to determine if the user is logged in? Thanks.
