Searching Zope sites?
by Alexander Staubo 10 Jun '99

10 Jun '99

Let me guess. This is a fairly frequently asked question? I'm using Zope 1.11.0pr1, and I'm looking for a simple way to permit full-text search, preferably including boolean expressions, on Zope sites. Looks to me like the only objects supporting the "Z Search Interface" are SQL Methods and Confera topics. Will full search capabilities come with the Portal Toolkit? Until then, is there a simple way to search through just, say, DTML Documents and DTML Methods? -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin.

Zope 1.10.2, Sessions and Z SQL Methods
by Eric Kidd 10 Jun '99

10 Jun '99

Under Zope 1.10.2, Sessions and Z SQL Methods do not seem to play nicely. Querying through a Z SQL Method (using the ZPyGreSQLDA, at least) appears to modify the method somehow. This means that if somebody's working in a session while a user is browsing the site, bad things tend to happen. This makes Sessions nearly useless. Does anybody know how I can work around this problem? Cheers, Eric

Hi, Seem to be having trouble getting my RewriteRule correct for authenticating. Cn some one take a look and see what is I am doing wrong here. This is a RHL 5.2, with Apache-1.3.3.

Permission mappings, Z Classes, and acquisition
by Alexander Staubo 10 Jun '99

10 Jun '99

Let's say I create a Z Class "Document" and define some new permission types. Then for some objects in my Z Class I create permission mappings, such as "Add Documents, Images, and Files" and "Delete objects" mapping to my permission type "Manage documents". Then I create some instances of the Z Class in the folder "Documents". I define a new global role "DocumentAdmin". I want this role to manage documents in the "Documents" folder and all subfolders. But there's the rub. I'd like to use acquisition to enable these security settings for all documents in this hierarchy. Zope only allows giving this permission to this role for each and every specific Z Class instance, because my custom permissions, such as "Manage documents", are not available on the folder level -- they're only available on instances. Is this a bug? Isn't the permission list supposed to be a superset of all available permission types defined in the database? Am I missing something? Because of this design, I guess I have to create a dummy Z Class called "DocumentFolder" which defines my custom permissions, then let the root folder be an instance of this class. Which is fine, but I didn't expect having to do this. If this is by design, I'd like to know the rationale behind it. Oh, and this is Zope 1.11.0pr1. -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin. Stop it.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_

University Website with Zope
by Troy Shurtleff 10 Jun '99

10 Jun '99

I a working on a more effective way to manage the website for a public university in North Carolina. Lately I have been considering Zope as a possible solution. I have spent some time using Zope and seeing what I can do with it. There are two features that are a priority in the web site... 1. We need to have a search feature where users from the web can enter a value in a search field and find documents that contain that text.....a fairly simple operation. I tried experimenting with the find feature in the Zope management interface. I was able to get close to what I want. I had to give anonymous users permision to view management screens. after some search criteria was entered a list of DTML Documents would appear that contained the text that I searched for. When I clicked on the documents it took me to the management screen for that document....from there i could view it. I would like to be able to better control the appearance of the output after a user does a search and I would like the user to be sent directly to a document listed in the search results.....without going through the management screen. 2. We would like to have a dynamically generated site map....this will probably only be avalible to administrators but possibly outside users. With the site map I would like to see what is linked to what...and if there are any broken links. I tried using the tree tag but nothing showed up.    is there something wrong with it? a tree view may be sufficient. I am currently running... Zope 1.10.2 (binary release, python 1.5.1, win32-x86), on Python 1.5.1 (#0, Nov 18 1998, 12:17:58) [MSC 32 bit (Intel)] on win32. Eventually we plan on installing Zope on our primary academic machine....unix....that is if we can implement the features we want. Any help would be greatly appreciated. Feel free to respond to this via e-mail to troy(a)mav.net Thanks Troy -- Troy Shurtleff troy(a)mav.net

Zope on a CD-ROM?
by spamfranke＠bigfoot.de 09 Jun '99

09 Jun '99

I'm trying to put my Zope app (1.10.2, Win NT) on a CD-ROM for demo purposes, using ZopeHTTPServer. I have a batch file whichs sets ZOPE_READ_ONLY before starting start.bat. It works fine when running from the harddisk. But on a CD-ROM I get the traceback below. Is the read-only mode not really read only? Stefan Traceback (innermost last): File "serve.py", line 100, in ?

Tree tag and SQL methods?
by Alexander Staubo 09 Jun '99

09 Jun '99

I don't have a head for figuring this out today, but maybe somebody here can help me out. I'm thinking of exploiting the #tree tag in conjunction with one or more SQL method. Say I have a hierarchical-ish table with id/parent_id references, and I'd like to display this information in a nice collapsible tree. Possible? Possibly the expr= or branches_expr= arguments to #tree could evaluate the result of an SQL method, although it sounds to me like this would require one query per tree level. Possibly you could put the query results of the complete table in a temporary variable and evaluate on that? Anybody done something like this? -- Alexander Staubo http://www.mop.no/~alex/ "`Ford, you're turning into a penguin. Stop it.'" --Douglas Adams, _The Hitchhiker's Guide to the Galaxy_

Sqishdot bug and issues
by Michel Pelletier 09 Jun '99

09 Jun '99

After getting Tiny Tables to work with Zope 2.0 with ZODB2 (effectivly "1.11", it won't work with ZODB3) I installed the Squishdot product. Tres cool, as Morgan would say if she could say more than "bye bye". Only problem is I get an error if I try and use either of the two style themes that require Tiny Tables (I keep wanting to type Tyny Tables) Squishdot work with the basic layout, and tiny tables works fine by itself: Traceback (innermost last): File /home/michel/dev/Michel/lib/python/ZPublisher/Publish.py, line 255, in publish_module File /home/michel/dev/Michel/lib/python/ZPublisher/Publish.py, line 161, in publish File /home/michel/dev/Michel/lib/python/ZPublisher/mapply.py, line 154, in mapply (Object: manage_addSquishdot) File /home/michel/dev/Michel/lib/python/ZPublisher/Publish.py, line 98, in call_object (Object: manage_addSquishdot) File /home/michel/dev/Michel/lib/python/Products/Squishdot/Squishdot.py, line 1464, in manage_addSquishdot (Object: ApplicationDefaultPermissions) File /home/michel/dev/Michel/lib/python/Products/Squishdot/Squishdot.py, line 405, in __init__ (Object: bipity) File /home/michel/dev/Michel/lib/python/Products/Squishdot/Squishdot.py, line 195, in addTable (Object: bipity) File /home/michel/dev/Michel/lib/python/Products/TinyTable/TinyTable.py, line 58, in addItem (Object: bipity) File /home/michel/dev/Michel/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_main) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_String.py, line 514, in __call__ (Object: manage_main) File /home/michel/dev/Michel/lib/python/App/special_dtml.py, line 120, in __call__ (Object: manage_tabs) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_String.py, line 514, in __call__ (Object: manage_tabs) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_With.py, line 133, in render (Object: _(manage_options=filtered_manage_options())) File /home/michel/dev/Michel/lib/python/DocumentTemplate/DT_Util.py, line 309, in eval (Object: _(manage_options=filtered_manage_options())) TypeError: sequence index must be integer -Michel asking a question for once
