[Fwd: Re: [Zope] test for the existence of a nodeValue]
by Jon Bowlas 05 Aug '05

Thanks Dieter, But I still cant get it to work. I've changed my get_attributes.py script to this: if not attobject: return '' version = attobject.get_viewable() nodes = version.content.documentElement.getElementsByTagName(attname) if not nodes: return '' nodeValue = nodes[0].childNodes[0].nodeValue if not nodeValue: return "none" return nodeValue and my zpt is like this: <span id="section_subheader" tal:define="isadditional python:here.get_uclattribute(attobject, 'ucl_additional_name')" tal:condition="python: isadditional !='none'" tal:attributes="id python:here.get_uclattribute(attobject, 'ucl_additional_name_color')"><span tal:content="python:here.get_uclattribute(attobject, 'ucl_additional_name') or nothing" tal:omit-tag="">Website Subheader</span></span> But I get the following error: Error Type: IndexError error Value: list index is out of range and the traceback says "Module None, line 7 in get_attributes" is the cause. Hope you can help.

FTP Failures on new install
by Steve McMahon 04 Aug '05

04 Aug '05

I've having trouble getting FTP working on a new Zope install. All other Zope functions appear normal, but I'm unable to transfer files _to_ Zope via FTP. I can use FTP to download files from the Zope server and can create new directories on the server. But attempts to transfer files to the server all result in "426 Error creating file" errors. > ftp> put test.html > 200 PORT command successful. > 150 Opening ASCII connection for test.html > 426 Error creating file. The problem is not a firewall problem; I can reproduce it with local ftp sessions and with no firewall in place. I've tried several Zope versions from 2.6 to 2.7.7. All have the same problem. Common to the attempts is that they were all source builds with Python version 2.3.3 (#1, Mar 10 2004, 06:42:32) [GCC 3.3.2] on Solaris 10 on a dual-Opteron Sun V20Z. I'd be happy to update the Python version if anyone thinks that might cure the problem. Thanks! Steve McMahon

Nothing in undo list
by robert rottermann 04 Aug '05

04 Aug '05

I created a folder and added a acl_users. When a user from this acl_users logs in and manipulates things in Zope and Plone he can not see anything in the undo_list. If I enter as a user that is declared in the root acl_users he can see and undo all the manipulations. Both of this users are managers. What could be the reason for this.? What sould I do that everyone can undo his/her modifications? thanks Robert

Installation of login_html Fails
by ktmi＠earthlink.net 04 Aug '05

04 Aug '05

Greetings, All- (thanks for all the help and tips from the list in the past...) The setup: I have created an internal web site that allows people in my organization to add and edit their own personal page. The problem is in installing into their folder (containing index_html, etc.) a login script (login_html) *programatically.* The steps: 1. Users create their personal folder and login userid and password as Anonymous Users as a role named "Friends." An "acl_users" user folder correctly installs. 2. A login_html method should then be automatically installed to the folder, in addition to a boilerplate "index_html" (this is installed correctly). 3. The index_html file acquires property values and other objects from the user entered information. 4. If the user wants to edit their page, they click "Edit," which should call "login_html." They enter their userid and pwd and editing is permissible. The problem is #2: I cannot figure out what permissions to give folders/objects that will allow Zope to add the login-html file programatically. (The above steps work perfect for the "Manager" role.) A login screen appears that refuses to accept any userid and pwd (except my "Manager" role's), the error message is: "Error Type: Unauthorized Error Value: You are not allowed to access login_html in this context Here is the python code called to add the boilerplate login_html to the newly created folder: **************************** id=userid doc = getattr(personal_folder,id) copy_info = container.personnel.personnel_temp.manage_copyObjects('index_html') doc.manage_pasteObjects(copy_info) copy_info = container.personnel.personnel_temp.manage_copyObjects('login_html') doc.manage_pasteObjects(copy_info) **************************** I'm stumped, tried changing every permission can think of, doesn't work. It all works fine other than this, and I really don't want to have to add the "login_html" file manually for hundreds of users... Hope you all can make sense of this, and much thanks in advance for any ideas!! Kevin (relative newbie)

Re: [Zope] Installation of login_html Fails
by ktmi＠earthlink.net 04 Aug '05

04 Aug '05

In case anyone is interested, using the python code below won't copy the file unless the "View" Security permission on "login_html" is turned on for Anonymous... Then to protect the page from other Anonymous visitors, I have to manually turn off the "View" Security settings of "login_html" after it's copied into the user folder. What a pain, anyone got a better way with some code? Thanks for reading!

PUT_factory fight
by Garito 04 Aug '05

04 Aug '05

Hi all I fighting with these PUT_factory def PUT_factory(self, name, typ, body): from Products.Yanged.FicheroYanged import FicheroYanged if name.endswith('.mm'): ob = FicheroYanged(name, 'Fichero de estrucutra de ' + self.getId(), body, 'LanzarProcesarFreeMind', self.getId(), typ) return ob return None It's curious because these function (put on the same container) works perfectly: def CrearFicheroYanged(self): """ """ from Products.Yanged.FicheroYanged import FicheroYanged ob = FicheroYanged('Fichero', 'Fichero de pruebas de ' + self.getId(), '', '', self.getId(), 'text/plain') self._setObject('Fichero', ob) return ob.getId() Could anyone find the mistake?

Thank you Puttaraju that was very good. I thought it would be something like this but I am a rookie-Zope so I can now go on and try with more confidence. Thank you Jim Abramson that was also some good piece for me. I will have it in mind. I 'll try it some weekend and give you the feedback here. ___________________________________________________________ Χρησιμοποιείτε Yahoo!; Βαρεθήκατε τα ενοχλητικά μηνύματα (spam); Το Yahoo!

But let me spin around yet: - Views: --- Editing/Creating business objects: ZPT's/DTML's with appropriate properties managing view concerns, genaralized for a category of possible (already standardised) business/zope objects (gaining from aquisition rules) --- Displaying Results: Pluggable Brains as subclass of above ones - Model : Perhaps Zope Products ???, handling business logic , I'm not sure if that would work, perhaps a so called workaround with.interfacing and so on. - Controllers: really PhytonSricpts, I think so, or alternatively dtml-methods So, why I'm asking: I want to implement a standardized web application (at this time it's only a stupid choose and buy like any other so called e-commerce/shopping cart system , but my intention is to make it almost configurable in all three aspects (i know ... but William S. wrote ################# #And enterprises of great pith and moment #With this regard their currents turn awry, #And lose the name of action. - Soft you now! #The fair Ophelia!
