TAL and Javascript
by Rob Boyd 29 Jun '05

29 Jun '05

Thanks to all the responders. It gave me some ideas, but alas no luck. To clarify, I am not trying to do everything in one request. Request one generates the page, a user event (selecting an option from a form) fires another request via javascript. like: <script tal:content="python:'function getFormats() { var widget = document.getElementById('orgs'); var chosen_org = widget.options[widget.selectedIndex].value; var formats = %s; // build selection 2 options from formats ' % here.getDataFormats(chosen_org)" /> And then a user event (onChange) calls getFormats. Even with generating the script with a Python script or DTML, the problem remains (for me at least) to get a value from the DOM passed as an argument to a Python script that queries my database. If my Python script didn't take an argument, I'd have no problem. I could do this and use javascript to build the select options from the appropriate values. But I'd like to cut down on what the browser has to handle. What the user chooses in the first selection can reduce what they get to choose in selection two from 3000 choices to hundreds. I'd prefer to have the backend reduce the result set rather than having the browser do the work. I thought about AJAX (no experience), but given time constraints, looks like I'll have to load everything on the page and go from there.

TAL and Javascript
by Rob Boyd 29 Jun '05

29 Jun '05

I'm stuck this, and would appreciate help or pointers. I have a form with 2 selection drop-downs. I want the user's choice of select 1 to drive the options displayed in select 2. When the user makes a selection in select 1, onChange calls a Javascript function that should write select 2 options based on the result of a call to a Python script, passing the select 1 choice as an argument to the Python script. But: I cannot get the Javascript var into the namespace that the TALES expression knows about. Example: <script> function makeDropDown() { var widget = document.getElementById('select1'); var choice = widget.options[widget.selectedIndex].value; var data = [result of calling Python script 'foo(arg)' with arg=choice] // create options for select 2 } </script> [various html...] <select id="select1" onChange="makeDropDown()"> [options...] </select> I've tried with multiple scripts, where one has tal:content=... but cannot figure out how the TALES expression can get at what my javascript gets from an event. I haven't done much with JavaScript inside Page Templates, so perhaps I'm going about this all wrong. TIA, Rob __________________________________ Discover Yahoo!

WebDAV

I'm using webdav to update to access files from Dreamweaver and it is working fine but when I try to use windows web folders feature it fails with the following error in zope log. It seems that windows is requesting the PROPFIND before authenticating. Any clues? Zope Version (Zope 2.7.5-final, python 2.3.5, linux2) Python Version 2.3.5 (#2, May 4 2005, 08:51:39) [GCC 3.3.5 (Debian 1:3.3.5-12)] System Platform linux2 Time 2005/06/27 15:05:48.973 GMT-3 User Name (User Id) Anonymous User (None) Request URL http://my.server/clientes/PROPFIND Exception Type Unauthorized Exception Value <strong>You are not authorized to access this resource.</strong> Traceback (innermost last): * Module ZPublisher.Publish, line 92, in publish * Module ZPublisher.BaseRequest, line 449, in traverse * Module ZPublisher.HTTPResponse, line 680, in unauthorized Unauthorized: <strong>You are not authorized to access this resource.</strong> Thanks in advance, -- Luiz Fernando B.

Sequencing pages
by John Poltorak 29 Jun '05

29 Jun '05

If I create individual pages for a website as sub folders of a sites main folder, how do I control the sequence of pages if I automatically generate a set of links to all the folders? I presume that under normal circumstances that sequence would be in alphabetical order of object ID. -- John

Please keep discussion on the list.

Possibly you have an old version of LDAPUserFolder that is not compatible with Zope 2.8? New versions can be downloaded here: http://www.dataflake.org/software/ldapuserfolder/ Or, hmmm, maybe you did not remember to install *any* of the Products that you had installed for zope 2.5? -- Paul Winkler http://www.slinkp.com

It is so much easier to wrap the call to wget in a shell, python, perl, whatever script. Then you can use a simple lockfile to see if another wget is still running in a copy of the script. It will take you 10 minutes and you will have solved the problem (at least for the use case of wget being run from the same machine). As for making a lock inside Zope, I have done this with setting a property: if treeroot.hasProperty('currently_parsing'): treeroot.manage_changeProperties( currently_parsing = True ) else: treeroot.manage_addProperty('currently_parsing', True, 'boolean') get_transaction().commit() For me it never worked inside the SESSION object (for my use case it does not matter that the session will do the locking only per user). After I'm done, I do: treeroot.manage_changeProperties( currently_parsing = False ) get_transaction().commit() I don't know if this is the proper or cleanest way to do it, but It Works(TM).

I don't understand still : what I am looking for is a way to read a url whitout having to write an external method. the point is I belived that reading a url in a web application like zope should not require such powerfull tool as external methods or dedicated products..

merging the contents of two acl_users folders
by Jim Abramson 28 Jun '05

28 Jun '05

Can it be done? If not that, the ability to move selected users from one acl_users to another would be a decent plan B. This is a one-time move, so I consider any effective solution viable, even if some manual hacking is involved. Thanks for any help, Jim

OFS.SimpleItem problem with maximum recursion depth exceeded Error
by Gautam Saha 28 Jun '05

28 Jun '05

Hi: I have a simple schema based on the "Article" ArchExample schema which uses the " RichWidget" for file upload. The product worked fine in Zope2.6.1/Plone1 but does not work in zope2.7.5-final/Plone2.0.5. I am getting a "RuntimeError: maximum recursion depth exceeded" error while trying to view the uploaded file ------- Traceback (innermost last): Module ZPublisher.Publish, line 175, in publish_module_standard Module Products.PlacelessTranslationService.PatchStringIO, line 51, in new_publish Module ZPublisher.Publish, line 132, in publish Module Zope.App.startup, line 204, in zpublisher_exception_hook Module ZPublisher.Publish, line 95, in publish Module Zope.App.startup, line 258, in recordMetaData Module OFS.SimpleItem, line 333, in getPhysicalPath Module OFS.SimpleItem, line 76, in <lambda> Module OFS.SimpleItem, line 310, in getId Module OFS.SimpleItem, line 76, in <lambda> ... ... Module OFS.SimpleItem, line 310, in getId Module OFS.SimpleItem, line 76, in <lambda> RuntimeError: maximum recursion depth exceeded (Also, an error occurred while attempting to render the standard error message.) ----- END Traceback I googled and found that it is zope bug (issue# 1253, URL:http://www.zope.org/Collectors/Zope/1253) I also, found similar this error is documented in Bug#928693 & 909894 in Plone2. Diater suggested a workaround (in zope Issue# 1253) which I don't quite understand being a python newbie. From Dieter: >This is a bug in "OFS.SimpleItem.Item_w__name__". > > In its base class, "__name__" is defined as > "ComputedAttribute(lambda self: self.getId())" > and it defines "getId()" to return "self.__name__". > Apparently, this is an infinite recursion. > >Please file a bug report to "http://www.zope.org/Collectors/Zope <http://www.zope.org/Collectors/Zope/1253/>". > >You can fix this problem by giving "Item_w__name__" a default >class level attribute or "__name__ = ''". > >You can work around the bug by assigning an "id" for your >object with its "_setId" method (this overrides "__name__"). Could someone please tell me where/what code I should make this changes? I posted this before in Plone list but did not get any response, may be because it is a Zope issue. My platform details: Zope Version (Zope 2.7.5-final, python 2.3.4, freebsd5) Python Version 2.3.4 (#2, Oct 21 2004, 17:49:27) [GCC 3.3.3 [FreeBSD] 20031106] Plone version: 2.0.5 Archetype version: 1.2.5-rc5 Any help is greatly appreciated.
