RE: [Zope] Dynamic HTML Forms

Thanks, Eric! I thought there might be something along these lines in Zope. I should have mentioned in my original message that I actually needed to pass several values from each record to the next page, so having them in a list is only workable if the order that they appear in the list is reliable. With so many web browsers out there, I didn't feel comfortable that the lists' ordering could be trusted, since there's no guarantee what order the browser will use to send the data to the server. Jim Penny had another example that added an index to the fields, a la my "value1" approach: http://www.zope.org/Members/jpenny/variable_length_forms This forces each value to have its own discrete name, so you can be sure you're getting what you need. I am, however, glad to know that this approach is available too, as there are places it will be invaluable. Thanks again! Sean

INSTANCE_HOME -> Trying to make my life easier.

I am trying to make my life easier by listining to what I am told... http://www.zope.org/Members/4am/instancehome Problem is I can not find the stop script anywhere in the Zope 2.4.0 Windows .exe that I installed as a manual start on Windows2000 in order to fulfill the instructions: "Edit stop so that the path it uses leads to the site's var, not the Zope installation." I assume not doing so causes the error message I am getting when I use the web UI to shut down the server: Site Error An error was encountered while publishing this resource. exceptions.SystemExit Zope has exited normally. Traceback (innermost last): File C:\Zope\2_4_0\lib\python\ZPublisher\Publish.py, line 223, in publish_module File C:\Zope\2_4_0\lib\python\ZPublisher\Publish.py, line 187, in publish File C:\Zope\2_4_0\lib\python\ZPublisher\Publish.py, line 171, in publish File C:\Zope\2_4_0\lib\python\ZPublisher\mapply.py, line 160, in mapply (Object: manage_shutdown) File C:\Zope\2_4_0\lib\python\ZPublisher\Publish.py, line 112, in call_object (Object: manage_shutdown) File C:\Zope\2_4_0\lib\python\App\ApplicationManager.py, line 411, in manage_shutdown (Object: LockableItem) SystemExit: 0 Can anyone help me?

Discovering the path and querying on it....
by Rustad, Aaron 17 Aug '01

17 Aug '01

I would like to query a table based on the current object I am working on. For example...I am trying to populate a menu, and I want it dynamically filled based on the page I am on. I know how to get the path, I am using : <dtml-var PATH_INFO> I have a Z SQL Method that looks like this: SELECT menu_item, link_path FROM page_links WHERE page_path = <dtml-sqlvar page_path type=string> What I want is to be able to populate page_path using something like this (I know it doesn't work): <dtml-in exec="page_links_query(page_path=PATH_INFO)"> <A HREF="menu_path"><dtml-var menu_item><BR></A> </dtml-in> Anyone know how I could do this? Thanks. Aaron.

acquisition and permissions (newby)
by Giuseppe Bonelli 17 Aug '01

17 Aug '01

Hi all, I need advice on the best strategy on how to manage hierarchical permissions without having to give up on acquisition. Here is my situation (quite standard, I guess): I have a top folder with a top ACL and a set of standard files (global.css, index_html, standard_html_*, breadcrumb_nav). I then have a subfolder with its own ACL. It could be nice I could acquire the standard files from the top folder without having to mantain multiple copies in the subfolder in order to avoid access errors. Currently I keep multiple copies of the standard files, but this is particularly annoying for the breadcrumb, as it must contain quite a lot of <dtml-try> in order to test the various PARENTS conditions, depending both on the role of the user and on the folder where breadcrumb lives in. I am sure I am doing something wrong !!! Any pointer would be appreciated, TIA, --peppo

Re: [Zope] changing ZClass bases
by Chris McDonough 17 Aug '01

17 Aug '01

Hi Mitchell, Please try to keep the discussion on the list... thanks! Yes... for instance if you create a Python class as a base class for a ZClass (by using one of several mechanisms... for an example see the ZCatalog Product's __init__.py where it does "createZClassForBase"), you can use a strategy where you subclass *only* from this class (it'll appear in the list of classes from which you can subclass in the ZClass creation interface). Then rebase that Python class to your heart's content without needing to rebase the ZClass at all. This works pretty well in practice.

Re: [Zope] get object's objectManager from python script

That helped a lot. I was really surprised when a search for 'parent' in the Help browser turned up nothing appropriate. I was even more surprised just now when a search for 'aq_parent' turned up nothing _at_all_! _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp

manage_clone and proxy roles
by Lee Harr 17 Aug '01

17 Aug '01

I have a folder "test" and in the folder "test" there is another folder "f". I want to have a method (preferably a python method) which creates a copy of "f" in the folder "test" and I want anyone to be able to do it (not just managers) so, I created a python method "c" as: context.manage_clone(context.test.f, 'f2') return "done" which works fine when I am logged in as manager, but throws up a login dialog when I am not. No problem, I figure, set the proxy role on "c" to 'Manager' and everything should be cool. Nope. Hmm. I think maybe this is not possible from python methods, so I try a dtml-method, as such: <dtml-call "manage_clone(f, 'f3')"> done Again, works fine when I am logged in as manager, but even if I set the proxy role on the method to 'Manager' I get the login dialog. This is one Zope 2.3.2 Any wisdom appreciated. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp
