Multiple site deployment
by Chui Tey 01 Apr '01

01 Apr '01

The project I'm doing will be deployed to several intranet sites. I'm developing content and logic in dtml plus a few external methods. Each site deployment will be customized. The customization is simple: basically changing the standard_html_header, smtp server name, and things like that. Dealing with software updates can be somewhat of a problem since I'll have to recustomize every data.fs before deployment? How are other developers handling this kind of customization problems? The Directory View from CMF looks to be useful in storing some of the customized dtml in the file system. I've tried ExtFile but it doesn't have external dtml documents. Has anyone used zope with configuration files before? Chui

I'd appreciate a couple. Standard problem with DTML Documents They bring with them there own context (DTML Methods won't) They define "tpValues" (used by "dtml-tree" to find children of a node) to return the empty sequence. Use either <dtml-tree "PARANTS[0]" ....> or a DTML Method rather than a DTML Document. Dieter

Opinions sought on acquisition issue
by The Famous Brett Watson 01 Apr '01

01 Apr '01

Hello folks. I encountered an issue whilst site-tweaking last night and solved it immediately, but it has me intrigued as to how more experienced Zopists than I might approach it. Any wisdom you'd care to share on the matter would be appreciated. I have a site which includes a "weblog" type arrangement, and I keep the log entries in a folder called "log". There's a subfolder called "images" for pictures that I might want to include in log entries. There's also an "images" folder in the root directory for site-wide graphics such as the site logo. Thus, in the context of the "log" folder, "images" means the log-specific images only. This means I can't address the site-wide image objects in this context without reference to PARENTS[-1] or similar. {Side issue: wouldn't it make sense to have "ROOT" or similar as an alias for PARENTS[-1]?} Specifically, I can't say "images['site-logo.jpg']" in a Python expression, since it will look in the wrong "images" container. I resolved this issue by renaming "images" in the "log" directory to "log_images", thus ensuring that they have distinct names. I was planning on making this distinct-naming my general approach in future. The "images" name makes more sense from a URL perspective, but the "log_images" name makes more sense from an acquisition perspective. The reason that this is an issue at all, however, is because identically-named container objects to not acquire the contents of the containers they mask, if any. The "images" folder in the "log" folder masks the "images" folder at the root, thus *hiding* the contents of that folder rather than *acquiring* the contents of that folder. What would the implications be for Zope if acquisition meant that a failed method invocation resulted in further traversal of the namespace stack instead of immediate failure? Thus, if I try to reference "images['site-logo.jpg']", and the first "images" object found does not contain 'site-logo.jpg', would it be a good, bad, or ugly thing for Zope to *continue* the search for "images" objects containing a 'site-logo.jpg'? A container's contents might not be the only thing one could acquire in this manner: perhaps other methods could also perform some kind of continued search for success if they encounter an exception early on? This might get very confusing. I await with interest your pontifications on this matter. Regards, TFBW

Re: [Zope] Zope Products and SQL

You can have many types of use of Z SQL methods from products: * use a Z SQL method instance located and managed in the Zope hierarchy. Such instances would usually be accessed through acquisition. * instantiate a new Z SQL method instance as part of your product instances * derive one of your product classes from Z SQL methods (though I think this is rather rare) * ....

REQUEST['AUTHENTICATED_USER']. has_permission('Add EW Nav Links', REQUEST.resolve_url(BASE0+getpath(data_record_id_)))) raised the "Unauthorized" exception (according to your traceback). In this expression, only "REQUEST.resolve_url(...)" and maybe "getpath" (if your user can not access the catalog, but that seems unlikely) can raise this exception. "REQUEST" and its methods are public, "has_permission" is public, "BASE0" is public (as part of "REQUEST"). > .... > <dtml-call "REQUEST.set('YihawFolders', [])"> > <dtml-in expr="Catalog({'meta_type':'Yihaw Folder'})"> > <dtml-if "REQUEST['AUTHENTICATED_USER'].has_permission('Add EW Nav Links', > REQUEST.resolve_url(BASE0+getpath(data_record_id_)))"> > <dtml-call "YihawFolders.append(getpath(data_record_id_))"> > </dtml-if> > </dtml-in> As a workaround, you could wrap your "if" into a "dtml-try". If you get an "Unauthorized" exception, it should surely not be in your "YihawFolders" list. Dieter

keeping zope running after closing ssh conection
by David Kelly 01 Apr '01

01 Apr '01

I have just installed zope on a linux ix86 box remotely using ssh...all went perfectly, managed to start zope and connect up to the control panel...all when my ssh connection was still open...as soon as I stopped it I lost contact with zope. Is there a way to start zope so that it stays running after I close the ssh connection? Another thing I need to know is the following: The server is a virtual hosting server and I am wondering if running zope is going to affect the other domains hosted on the same box...I dont want to cause problems....can anyone give me any ideas about how running a site with say 1500/2000 pagereads a day and 1 gig of tranfers per month will do to the environment? Anything I should avoid doing especially?...configurations that can be adjusted? regards to all David
