Re: [Zope] Can't get "objectIds()" (and others) from XML-RPC

Ah, now then. You've hit some of the problems of XML-RPC here. There is no way to pass named params with XML-RPC. XMLRPC also can't handle 'None' or NIL or anything that means undefined. You could try and work around this by using a dictionary of params rather than simple params. ----- Original Message ----- From: "Gilles Lenfant" <glenfant(a)bigfoot.com> To: "Phil Harris" <phil.harris(a)zope.co.uk> Sent: Friday, May 11, 2001 12:52 PM Subject: Re: [Zope] Can't get "objectIds()" (and others) from XML-RPC > Many thanks Phil ! > It worked at first attempt ! > > Hmmm. additional question for this kind of workaround : > I need support for optional arguments in a Zope python script, just like > this in "natural python" > > def stuff(param=None): > if param: > # do it with provided param > else: > # provide default param > param = [] > > I've tried to put "param=None" in the parameter list of the zope management > screen but it seems that it remains like "None" when I provide data for the > "param"... > > This is just for using "objectIds()" and "objectIds('DTML Method')" with the > same Zope python script "myObjectIds" > > TIA again > > Gilles > > ----- Original Message ----- > From: Phil Harris > To: Gilles Lenfant ; zope(a)zope.org > Sent: Friday, May 11, 2001 12:45 PM > Subject: Re: [Zope] Can't get "objectIds()" (and others) from XML-RPC > > > Yes, you did! > > The objectIds are no longer callable via a URL, they can only be called from > DTML or Python (internal and external). > > This means that you can't call it via XML-RPC. > > Don't lose hope though, here's how to get around this limitation. > > Create an Internal Python Script in the root of Zope, with these contents: > > return context.objectItems() > > This will return the list and all will be well. > > You should though have some security on this method, otherwise *everybody* > will see the contents on your Zope instance. > > > > > Thanks in advance for any hint. > > > > > > _______________________________________________ > > Zope maillist - Zope(a)zope.org > > http://lists.zope.org/mailman/listinfo/zope > > ** No cross posts or HTML encoding! ** > > (Related lists - > > http://lists.zope.org/mailman/listinfo/zope-announce > > http://lists.zope.org/mailman/listinfo/zope-dev ) > > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://lists.zope.org/mailman/listinfo/zope > ** No cross posts or HTML encoding! ** > (Related lists - > http://lists.zope.org/mailman/listinfo/zope-announce > http://lists.zope.org/mailman/listinfo/zope-dev )

Can't get "objectIds()" (and others) from XML-RPC
by Gilles Lenfant 11 May '01

11 May '01

Hi group... I'm trying to use XML-RPC server features of ZOPE using Fredrik Lundh's xmlrpclib and the BasicAuthTransport class explained in Amos Latteier's Howto http://www.zope.org/Members/Amos/XML-RPC. I've tried to do some stuffs explained in Amos's article at http://www.xml.com/lpt/a/2000/01/xmlrpc/index.html I succeeded reading a DTML document with server.document_src() but when trying to get a folder objects list, like in the example: <python> from xmlrpclib import Server from BasicAuthTransport import BasicAuthTransport srv = xmlrpclib.Server('http://localhost:8080/anyfolder', BasicAuthTransport('myself', 'mypassword')) print srv.objectIds() # raises the xmlrpclib.Fault exception </python> I got always this exception ! <console> Traceback (most recent call last): File "./userlist.py", line 10, in ? print srv.objectIds() File "/usr/lib/python2.1/site-packages/xmlrpclib.py", line 539, in __call__ return self.__send(self.__name, args) File "/usr/lib/python2.1/site-packages/xmlrpclib.py", line 622, in __request request File "./BasicAuthTransport.py", line 46, in request return self.parse_response(h.getfile()) File "/usr/lib/python2.1/site-packages/xmlrpclib.py", line 593, in parse_respo nse return u.close() File "/usr/lib/python2.1/site-packages/xmlrpclib.py", line 367, in close raise apply(Fault, (), self._stack[0]) xmlrpclib.Fault: <Fault -2: 'Unexpected Zope error value: <html><head><title>D ... </TD>\n\n<TD WIDTH="90%">\n <H2>Site Error</H2>\n An error was encountered while publishing this resource. \n Resource not found Sorry, the requested resource does not exist.Check the URL and try again.  <HR NOSHADE> Troubleshooting Suggestions\n\n <UL>\n <LI>T he URL may be incorrect.</LI>\n <LI>The parameters passed to this resource may </console> "objectIds" method is not the only one that raises an exception. When using methods inherited from class "ObjectManagerItem", it works but I got similar exception when using other methods inherited from class "ObjectManager". As mentioned in the API doc, a folder is supposed to be a subclass of "ObjectManagerItem" and "ObjectManager". Did I miss something ? Thanks in advance for any hint.

It should look something like this in your product...: manage_options = ( {'label':'Edit', 'action':'manage_main'}, )+PropertyManager.manage_options+\ SimpleItem.manage_options manage_main above must have the right permissions also... from AccessControl import ClassSecurityInfo security = ClassSecurityInfo() security.declareProtected('View management screens', 'manage') Then your manage dtml should look something like this... <dtml-var manage_page_header> <dtml-with "_(management_view='Edit')"> <dtml-var manage_tabs> </dtml-with> This is the edit form. <dtml-var manage_page_footer> /Magnus

Zope.org webpage Members section (right place to post question?)
by Peter Bengtsson 11 May '01

11 May '01

In my members section, I have a folder full of DTML Documents with some example code that I would like to display the document_src of. Isn't that possible? It requires loggin in, and I can't change the secutiry settings of the subfolder to let Anonymous Users look at the document_src. Any other page can be seen using the DTML Source link at the bottom. help.please.peter

Hi All, I've recently fallen in love with zope, using it for 2 large charity projects I am doing in my free time. Does anyone know of any zope hosting companies based in the UK and/or do you think there would be demand for such a monster? Regards, Dan

RE: [Zope] silly IE display question - manage screens showing 'vi ew', not contents
by Meilicke, Scott 11 May '01

11 May '01

I don't - I have a laptop on win2k, and usually just 'Hibernate' - suspend to disk, instead of shutting down and restarting in the morning. I performed an update via windowsupdate.microsoft.com a few days ago and did not reboot when prompted because I was in the middle of something. I rebooted this morning, and it works fine now. For what it's worth, I'm currently running IE 5.5, sp1, version 5.50.4522.1800. Oddly enough I had the same problem last night with Netscape - once. Unfortunately I don't remember exactly what I did to correct it, but my site prompted me to log in again via a windows logon window, not the usual web logon. Sorry I didn't write down exactly what I did... Thanks for the help.

styled text editing
by Alex Burton 11 May '01

11 May '01

Hello All, not a pure Zope question here: I'm investigating solutions to input and manipulate styled text that will end up in a SQL database. It should probably be a simple interface to HTML. The goal is to allow writers to input styles into text (such as putting titles in italic, personal names in bold) without having them do HTML or structured text, nor cut&paste into a visual HTML editor. This SQL data will head one way back onto the web (live zope) and the other way into a print layout program (probably as an XML file). What i would need is , , , , <hn>, maybe <dir> based on tabs, you know, just the basic stuff. Possibilities i can think of: A Java applet that talks to Zope or SQL (like the new(?) hotmail editor). A Flash file that talks to Zope (assuming there is a Flash widget to do such editing) An SQL-aware app on the desktop (made in VBasic or something like that) ...? It actually does not have to be HTML, as long as Zope can deal with it (can go in a SQL blob). Anyone worked or stumbled upon something like this? We may have some resources to do development towards this, so general pointers and ideas are also welcomed. Thanks, Alex.

user roles in standard_error_message
by Danny William Adair 11 May '01

11 May '01

sorry sorry sorry, I just reinstalled my email client and didn't turn off html sending... sorry Hi! While customizing my standard_error_message, I ran into a little problem: Someone with the role "Member" is logged in and tries to access a resource that does not exist. Same could happen to someone who doesn't have that role (Anonymous). Now I have two different style sheets for members and non-members: A member might click on a broken link from within the members-only area (having a... pink background), the anonymous user clicked the same broken link from a publicly accessible area of the site (having a... silver background). I would like to keep the different background colors when showing my error message so I put a <dtml-if "AUTHENTICATED_USER.has_role('Member')"> <dtml-var "members_css"> <dtml-else> <dtml-var "public_css"> </dtml-if> in the head section of standard_error_message (these *_css are ZStyleSheets) My problem is, that it's always the public_css that will show up. So I checked with <dtml-var "AUTHENTICATED_USER.getRoles()"> in both the members area and standard_error_message. To my surprise the member role was gone: In the members area getRoles() returned ('Member',) while in standard_error_message ( _.str(error_type)=='NotFound' ) it returned ('Anonymous',) btw, the role is not really "lost", I can go back to the members area and click through members-only pages without problems. What's happening? This looks like buggy, naughty misbehavior :-), doesn't it? tia, Danny

forcing a ZEO client to retrieve something from it's server.
by Anthony Baxter 11 May '01

11 May '01

For testing the state of a system, I want to be able to do a request that confirms that a ZEO client is alive, and that it's backend server is alive. I know I can do something like a write, but I really, really don't want to do that - Data.fs bloat. Is there a way to make a ZEO client get something from the server? Can you make an object that the ZEO client won't cache? ta, Anthony
