Re: [Zope-dev] Separate staging and development areas for a product
by A M Thomas 23 Apr '02

23 Apr '02

I mentioned this in a follow-up message I just posted to an earlier question of mine, but found this thread and wanted to mention: I'm an independent very small web developer, and my clients are small, too. I have in-house machines, but only one Zope web server (an iMeme account). It just isn't possible for me to have separate machines, or even an additional account. iMeme may let me set up a separate Zope instance, but it would be _very_ nice if I could work on a single Zope instance and have a development and production version of my product. I have machines at my home office that I can install Zope on, including one with Zope already installed, but I really need my development version accessible to the internet, too. And it would be nice to have three versions so I could have a separate testing version public, as well. What should someone like me do in order to develop a product that is also in use on my server? What do other independent developers do? Thanks, Am -- http://virtueofthesmall.com

Hello Tres, >> If you would, please try the attached patch and see if it helps. Thanks a lot for your help : i don't really understand how it work... but it works !! I'll put this bug into the tracker ASAP. But there's a another little problem : the "MetaDataTool.py" with your patch doesn't still works with the ZMI. >> Votre anglais est tres superieur de mon francais. :) Not so bad ! ;-) Thanks. Fred.

Why ? The ZMI version is a class method, and hence operates as "trusted" code; it doesn't surface the bug you found. The 'getElementSpec' method returns the ElementSpec instance without wrapping it in itself, which means that your DTML method cannot do the security checks properly.

path notation
by Dennis Allison 23 Apr '02

23 Apr '02

There ought to be an easier way .. Suppose I have a folder structure A-B-C-D | E-F and an object in D needs to reference an object in F, the reference is resolved by writing a set of nested dtml-with statements, first referencing B, then E, and finally F. B is found by acquisition, but traversion the path has to be explict. It's a pain to write and puts information about the site organization more deeply into the methods than I would like. I'm sure there's a better way to manage things, but I have not a clue. Can someone point it out? A related problem arises when some of the path is computed. For example C-D-E A-| C'-D'-E' is a fairly common structure in one of my sites. I compute the choice between C and C' and then try to construct a path, but it keeps giving me referece errors, I suppose because the thing I compute is a string and not the object (duh...). I suppose I need to use getattr() to find the associated object :-) -d

ZClass edit with a PythonScript
by Tim Wilson 23 Apr '02

23 Apr '02

Hi everyone, I've built a more user-friendly edit form for a ZClass-based product. Now I'd like to use a PythonScript as the action of the form to actually process the changes. I think I'm 90% there, but I can't figure out how to refer to the object that needs to be changed in the Script. In the current version (included below), I'm referring to the object as 'newsitem', but how to I connect that name with the object itself? Here's the code: ## Script (Python) "doEdit" ##bind container=container ##bind context=context ##bind namespace= ##bind script=script ##bind subpath=traverse_subpath ##parameters= ##title=Edit a NewsClass instance ## REQUEST = container.REQUEST newsitem.propertysheets.Basic.manage_changeProperties(REQUEST) if REQUEST['body'] != '': newsitem.propertysheets.Basic.manage_changeProperties(readmore=1) else: newsitem.propertysheets.Basic.manage_changeProperties(readmore=0) newsitem.reindex_object() RESPONSE = REQUEST.RESPONSE if REQUEST.has_key('DestinationURL'): return RESPONSE.redirect(REQUEST['DestinationURL']+'/manage_workspace') return RESPONSE.redirect(REQUEST['URL2']+'/manage_workspace') Any hints would be appreciated. -Tim -- Tim Wilson | Visit Sibley online: | Check out: Henry Sibley HS | http://www.isd197.org | http://www.zope.com W.

security issue!
by Iago 23 Apr '02

23 Apr '02

The setting: I have a folder (call it foo/bar), on which I've unchecked Acquire Permissions Settings and checked Authenticated, so logins should be enforced when attempting to access that folder. In foo, I define the index_html method. In foo/bar I have file.txt The issue: If I try to access foo/bar, I do not get authenticated -- it _seems_ to be going by the permissions govering foo/index_html, instead of foo/bar (before accessing) foo/bar/index_html (and then, lacking that, inheriting). If I try to access foo/bar/file.txt, I get asked to authenticate. This is wholly counterintuitive to someone who first did his authenticating years ago using .htaccess files -- permissions on a folder should affect attempts to acquire any resource within that folder, *regardless* of whether that resource is inherited or not! Is there a fix to this that doesn't involve the (less scalable) notion of copying the index_html method from the top into this directory? Thanks -- Fred Hicks <iago(a)iago.net>

login as member and manager with one browser on CMF
by Florian Konnertz 23 Apr '02

23 Apr '02

Hi to all, Is it possible to login as a user and manager in two windows with the same browser on CMF? To login as a certain user I shutdown my mozilla completey, and call CMF with the users homepage URL. Then I open a second window as a manager and login. If I do anything in the user window, I find me logged in as the manager in the reply window. How can I avoid this? Switching off cookies? No - Then I have to enter the pword everytime, haven't I?? Thanks, Florian

Inserting a variable in a context.manage statement in Python
by Dan Shafer 22 Apr '02

22 Apr '02

Is it possible to insert into a context.manage* statement a variable previously assigned in a Python script? If so, what's the syntax? I have the following: c = REQUEST.get('clearing_id','') context.manage_addFolder(c) # this works # Now what I want to do is add a document to the folder # If I include a hard-coded value for the folder name I just created as a test, it works # But this doesn't: context.c.manage_addDocument('NewDoc') I always get an AttributeError on 'c' which, if I understand correctly, is telling me that internally Zope is trying to do a getattr() on something to resolve c and not being able to do so. I'm guessing I need some kind of delimiter around the variable c here but I'm darned if I can figure out what that might be! I have tried every combination I could come up with after perusing the HOW-TO and Tip files for Zope, to no avail. Assuming the manage_addDocument method ends up calling addDTMLDocument in DTMLDocument.py, II can't see for the life of me why what I'm doing doesn't work. But it doesn't.
