How do I do this using Zope?
by John Poltorak 09 Mar '06

09 Mar '06

I would like to create a folder (news) which contains several news items, lets say news1, news2, news3. I would like to set up a menu box which lists all the news items in the news folder which when clicked on would load each one up. How do I code this up? (Hope someone understands what I'm getting at) -- John

RE: [Zope] manage_pasteObjects question

Hi David, I reviewed OFS.CopySupport.py which is how I knew that eInvalid exception is being raised. I also called manage_cutObjects with the REQUEST as you mention. That's what is weird about this whole thing. I know that I had clipboard data and the __cp cookie is set. Everytime I tried to do the paste, I'd get the "cookie truncated" message. You're right about the documentation. As with most Zope documentation, it's not that great. Lately, I go straight to the source. I find I learn more that way. Thanks, Tom _____ From: David [mailto:bluepaul@earthlink.net] Sent: Thursday, March 09, 2006 12:44 AM To: Palermo, Tom Cc: 'zope(a)zope.org' Subject: Re: [Zope] manage_pasteObjects question Palermo, Tom wrote: Hi David, In my last post, I wrote that I tried calling manage_pasteObjects a variety of ways: context.manage_pasteObjects(context.REQUEST) context.manage_pasteObjects(context.cb_dataItems()) as well as the original: context.manage_pasteObjects(cb_copy_data=context.cb_dataItems(),REQUEST=req[ '__cp']) All 3 of these attemps results in the eInvalid exception gettting raised by manage_pasteObjects( ). req['__cp'] is a reference to the cookie that gets set when you place something on the clipboard.

It's one of those times when I just need something to work. -Tom _____ Hi Tom, I'm glad you found 'another way' but in the interest of no one I wish to add the following. These methods: manage_copyObjects, manage_cutObjects and manage_pasteObjects should be reviewed in /OFS/CopySupport.py - because the current docs do not describe them well. For example, the copy method works differently depending on whether you just pass the container's Ids or pass the Ids *and* the REQUEST. No reason to beat a dead horse but of the 3 tries you listed only the first can (but conditionally) work: context.manage_pasteObjects(context.REQUEST) But *only* if you first called manage_copyObjects (or manage_cutObject) with the REQUEST as a parameter included .... (only then does REQUEST get the __cp object) Your second try: context.manage_pasteObjects(context.cb_dataItems()) Is wrong because it is passing a list of items in the clip board instead of the the encoded copy object (returned by manage_copyObjects) that "manage_pasteObjects" expects Your last try is wrong because both parameters are incorrect. :-) All best, David

getView/getMultiAdapter and 'global name 'view' is not defined'
by Maciej Wisniowski 09 Mar '06

09 Mar '06

Hello I have a view defined for my content class that uses both view template and view class. In zcml it looks like: <browser:page for=".xyz.IXyz" class=".browser.xyz_view.XyzView" template="xyz_body.pt" name="render" permission="zope2.View" /> in 'xyz_body.pt' I have statements like: ------------------------------------------------------------------------ <div tal:define="xyz_dict python: view.xyz_function();"> ------------------------------------------------------------------------ where 'xyz_function' is defined in 'XyzView' class. Calling @@render from another view or directly by URL in browser works, but when I'm using: ------------------------------------------------------------------------ rnd = zapi.getMultiAdapter((self.xyz_instance, self.REQUEST), Interface, name='render') ------------------------------------------------------------------------ or ------------------------------------------------------------------------ rnd = getView(self.xyz_instance, 'render', self.REQUEST) ------------------------------------------------------------------------ where 'xyz_instance' is a instance of content class (in ZODB) that implements IXyz I get: ------------------------------------------------------------------------ NameError Exception Value global name 'view' is not defined Traceback (innermost last): Module ZPublisher.Publish, line 114, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 40, in call_object Module Products.XyzBase.XyzBase line 178, in save_form Module Products.XyzModule.xyz_emailer, line 51, in save_data Module Products.Five.browser.metaconfigure, line 403, in __call__ Module Shared.DC.Scripts.Bindings, line 311, in __call__ Module Shared.DC.Scripts.Bindings, line 348, in _bindAndExec Module Products.PageTemplates.PageTemplateFile, line 110, in _exec Module Products.PageTemplates.PageTemplate, line 104, in pt_render <ImplicitAcquirerWrapper object at 0xb351b80c> Module TAL.TALInterpreter, line 238, in __call__ Module TAL.TALInterpreter, line 281, in interpret Module TAL.TALInterpreter, line 507, in do_setLocal_tal Module Products.PageTemplates.TALES, line 221, in evaluate URL: index Line 1, Column 0 Expression: <PythonExpr view.xyz_function()> Names: <...cutted here...> Module Products.PageTemplates.PythonExpr, line 70, in __call__ __traceback_info__: view.xyz_function() Module <string>, line 2, in f NameError: global name 'view' is not defined ------------------------------------------------------------------------ How can I call such view from python code? I'm using Zope 2.9.1. In Zope 2.8.5 it was possible to use context.xyz_function() instead of view.xyz_function() but now it causes errors. One more question - is it necessary to inherit from Products.Five.BrowserView in view class? I think that I've found somwhere that ZCML itself puts BrowserView into base clases of view class...? -- Maciej Wisniowski

call htmlformuploadfile from dtml method
by Olivier Wambacq 09 Mar '06

09 Mar '06

hello, in plonelocalfolderNG you have the htmlformuploadfile method, that is called in the form action. but I needed to save everything in a db also, so I called a dtml method in the form action. whitch first calls the db-store scripting, and then the htmlformuploadfile. everything is stored well in the db now, but now I don't know how to call the htmlformuploadfile from this script. I tried some things like: <dtml-var htmlformuploadfile> or <dtml-var http://....../htmlformuploadfile> also tried using <dtml-call ... but nothing seems to work, he always says htmlformuploadfile doesn't exist. I tought I just had to call the same thing as in the action argument, but how do I know how to call it when I call it from a dtml method instead? thanks in advance Olivier

Help needed to simplify some code
by John Poltorak 09 Mar '06

09 Mar '06

Several months ago someone provided me with me with some sample code which did exactly what I wanted, but looking at it again it looks a little unwieldy and could do with tidying up. It consists of:- <span tal:define="opts python:here.lib.parse_file(file=here.news,sepr=',',clone=1)"> <tal:block repeat="opt opts"> <li><a tal:content="python:opt[1]" tal:attributes="href python:'news_items/' + opt[0]"></a></li> </tal:block> </span> which involves parsing a file containing two fields separated by ',' eg. 001,abc 002,jkl 003,xyz The second field is just a string which appears in a selection menu, and the first is the name of a folder which contains an object called 'content' which get displayed on selecting the correponding link. I know this is not a particularly elegant way of doing it, but after looking at some TAL examples just can't figure out the right way to do it. Some help in simplifying it would be appreciated. -- John

Upgrading best practices
by Brian Sullivan 09 Mar '06

09 Mar '06

Is there somewhere a general guide to upgrading existing Zope systems to newer versions? I realize that there are special cases but I am looking for a general best practices guide. It seems that there is lots of information with each release on installation from scratch but very little solid information that I could find on upgrading.
