SiteAccess guidelines
by Alexander Limi 15 Jan '00

15 Jan '00

Zopistas, I'm trying to use SiteAccess to do some redirection on our site. The main idea is this: All folders that do not exist should be redirected to another folder, where they might or might not exist. The way I've tried to implement this is as follows: All calls to URLs except some selected few (more on this later) are redirected to my "artists" folder. Eg: http://mp3.no/bandname is redirected to http://mp3.no/artists/bandname. The SiteAccess rewrite rule looks like this: <dtml-unless "REQUEST.path and REQUEST.path[0][:6]=='manage'"> <dtml-unless "REQUEST.path and REQUEST.path[0]=='players'"> <dtml-unless "REQUEST.path and REQUEST.path[0]=='artists'"> [actual rewrite code] This should except the folders [root]/artists, [root]/players and the manage console. But I would like to have the best way of redirecting everything, except the root of the site and some subdirectories that I list. The above solution is wildly inelegant :) In addition, my crappy piece of redirect also redirects root, which it shouldn't do. To exemplify some more: http://mp3.no should point to root http://mp3.no/artists should point to /artists/index_html http://mp3.no/players should point to /players/index_html http://mp3.no/bandname should point to /artists/bandname/index_html http://mp3.no/anything should point to /artists/anything etc... Evan, do you hear my call of distress? :) Regards, Alexander Limi http://mp3.no

SiteAccess, ZZClass, and Set Access Rule
by J C Lawrence 15 Jan '00

15 Jan '00

I've installed SiteAccess 2.0, and am attempting to set an access rule for a ZClass that I'm defining. The problem is that everytime I attempt to define one of my DTML methods as an access rule it returns (eg): "ProcessURL" is not the Id of a method of this object If however I go and create a "real" folder, not a ZCLass, and put the same ProcessURL DTML method in as an access rule, it works fine. Is it not possible to define an access rule for a ZClass? FWIW the problem I'm attempting to solve is to have an URL. sauy: http://site/X/ and to then have all the cruft after the X be pre-processed as the seeds of an SQL query, so that for instance: http://site/X/Q/R/S would go and dig up some set of nested SQL queries based on Q, R, and S and then throw them at the index_html in X. SiteAccess seemed the way to do this... -- J C Lawrence Home: claw(a)kanga.nu ----------(*) Other: coder(a)kanga.nu --=| A man is as sane as he is dangerous to his environment |=--

calling other methods?
by James Punteney 15 Jan '00

15 Jan '00

Hello, I have a page that inserts another page using dtml-var. The page that is being inserted is up a couple of directories and then down a directory. I am referencing it as: <dtml-var "cds.clients.comboActive"> The problem is that with the quotes it does not interpret the dtml statements in "comboActive" (it changes the <> to < >). If I do not use the quotes (<dtml-var cds.clients.comboActive> or <dtml-var /cds/clients/comboActive>) it comes up with this error: Error Type: KeyError Error Value: /cds/clients/comboActive Troubleshooting Suggestions This resource may be trying to reference a nonexistent object or variable /cds/clients/comboActive. How can I get Zope to include the page, and execute the dtml statements? Thanks for the Help, --James Punteney

Sophisticated Editing of Zope Objects
by schenck 15 Jan '00

15 Jan '00

I am new to using Zope. It looks very interesting, but one thing that appears to be a weakness is the way you edit DTML Documents and Methods (and other objects too for that matter) by using a simple text field in an HTML browser. For complex objects this looks like a serious problem. Other than exporting the object, editing it in a more sophisticated browser and importing it again, are there better solutions? Thanks for the help. Dan ------------------------------------------------- Dan R.

Using ZOracleDA in external methods
by Nemeth Miklos 15 Jan '00

15 Jan '00

In my application I need to call PL/SQL stored procedures returning data in their OUT arguments. Z SQL methods do not support OUT or IN/OUT arguments. I'd like to call DCOracle methods directly, but I need the very connection object allocated by the ZOracleDA object for the application thread. The majority of database manipulation tasks are done by Z SQL methods, and my external functions (calling these stored procedures) have to share the transaction context. How to get the connection object of the application thread from a ZOracleDA object? I browsed the source code but I am not trained enough to figure out myself. NM

I should have mentioned : <stml-var ZopeTime> There have been several messages re. to this topic, timezone issues, and GMT (Greenwich Mean Time) in the last few days. Scan up the list to get some ideas. Even though the title doesn't seem related, some of the "REQUEST.set not incrementing" messages have ZopeTime examples. Later, Jerry S.

Hi James ! > Neither the Issue or Article will know about how the article is to > ultimately be formatted (actually the article contains minimal HTML > formatting, but these objects don't know whether they will be contained in > tables, frames, etc.) You have a Model which contains the domain objects issue and article.

This way, the Catalog would provide you with the objects, and you neither have to explicitly create the aquisition path, nor do you have complicated URLs like they are used on traditional web sites. You just have an URL like: http://foobar.news.com/NewsPage http://foobar.news.com/HomePage http://foobar.news.com/IssuePage I add some suggestions how the views could look, but I must say that these are just simple ideas and that the code is untested. I just want to get the idea across. NewsPage view: <dtml-in "Catalog( meta_type=Article, issue=20001001, article=1)"> <a href="<dtml-var "Catalog.getpath(data_record_id_)">"> </dtml-in> Homepage_View <dtml-in "Catalog( meta_type=Article, issue=20001001)"> <dtml-if top_story==1> <a href="<dtml-var "Catalog.getpath(data_record_id_)">"> </dtml-if> </dtml-in> IssuePage <dtml-in "Catalog( meta_type=Article, issue=20001001)"> <a href="<dtml-var "Catalog.getpath(data_record_id_)">"> </dtml-in> > I've been playing around with my new scheme for a little bit and so far I > like it.

You have only talked about Views and Objects, and not about Controllers. Where do you place the Data Management Object ? How do writers add articles and edit them ? Views don't change objects, they just display them, and objects don't know what to do with themselves. Greetings, Maik Röder

Actually, it doesn't work that way at all. I must have repressed the hours it took to verify that you can't use a fmt=XXX in REQUEST.set. You can do this, however : It is now <dtml-var "_.DateTime()" fmt="AMPM">. BTW, see http://lists.zope.org/pipermail/zope/1999-September/009657.html Later, Jerry S.
