Trapping error messages.

Some folks asked about this a bit ago, so here it is: first, check out how the zopester's do it: http://www.zope.org/standard_error_message/view_source so, there is a variable error_type, and it appears, from the Zope Quick reference (look for setStatus) to have the following string values: OK, Created, Accepted, NoContent, MovedPermanently, MovedTemporarily, NotModified, BadRequest, Unauthorized, Forbidden, NotFound, InternalError, NotImplemented, BadGateway, ServiceUnavailable these may not all be valid values of error_type (I doubt OK is.) anyway, the ZQR is at http://www.zope.org/Members/ZQR so, in standard_error_message, you can do a sequence of <dtml-if "error_type == errorhere"> <dtml-var thisError_response> <dtml-var standard_html_footer> <dtml-else> <dtml-if "error_type == nexterror"> <dtml-var otherError_response> <dtml-var standard_html_footer> <dtml-else> <p>Something is wrong, something is terribly wrong</p> </dtml-if> </dtml-if> -- ~mindlace

FW: [Zope] Authorization failure

sture: <dtml-tree branches_expr="objectValues(['Folder, 'File'])" sort=meta_type skip_unauthorized> <dtml-var title_or_id> </dtml-tree> -----Original Message----- From: Sture Lygren To: zope(a)zope.org Sent: 10/2/99 2:51 PM Subject: [Zope] Authorization failure Hi! I'm stuck with a problem here and hope someone can help me out ... I try to make a folder & file tree view using the code: DTML-method - show_tree <dtml-tree branches_expr="objectValues(['Folder, 'File'])" sort=meta_type> <dtml-var title_or_id> </dtml-tree> Accessing the show_tree method as manager displays all correctly, but when I try to access the method as another user I get 'authorization failed'. I find this strange since the user has aquired the permissions : 'access contents information' and 'view' to the methods parent folder, the same permission setting is set for the folders and files therein. I can trick it so that the user is proxyed as manager on the method, but thats not what I want - I will block access to all but the authenticated users private files and folders in the future. Please tell me whats I do wrong and how I can fix this. Thanks in advance Sture Lygren _______________________________________________ Zope maillist - Zope(a)zope.org http://www.zope.org/mailman/listinfo/zope (Related lists - please, no cross posts or HTML encoding!

ben, it worked! except I had to do the following (I am working from the IMAPAdapter.py with the string "__version__='$Revision: 1.5 $'[11:-2]" at the top): comment out lines 202 - 203 e.g. replace: if 'NotMail' not in roles: return None with # if 'NotMail' not in roles: # return None then after line 204 (parent=request['PARENTS'][0]) add: if auth==None: return None then in lines 106, 107, 108, change: def addIMAPAdapter(self, title='', default_domain='', smtp_server='', smtp_port=25, imap_server='', imap_port=143, roles, REQUEST=None): to: def addIMAPAdapter(self, title='', default_domain='', smtp_server='', smtp_port=25, imap_server='', imap_port=143, roles=None, REQUEST=None): Then the sample code worked.

After much time and effort I have managed to get this working. I'm not sure if it is a genuine bug or something I've missed along the way but if you edit IMAPAdapter.py in the validate function. (Line: 200) First comment out the following lines: if 'NotMail' not in roles: print 'Notmail not in roles' return None Then add: if auth == None: return None after: parent=request['PARENTS'][0] Mmm, hope this helps, this worked for me.

Zope-Apache Virtualhosting problem
by Roché Compaan 02 Oct '99

02 Oct '99

I'm trying to set up Apache and Zope with virtual hosts and I'm struggling a bit with the final hurdle. I've only tried to deliver Zope pages on the one virtual hosts. My entry in my apache virtual host looks like this: RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteCond ^/Zope(*.) /home/httpd/cgi-bin/Zope.cgi/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] When I open my browser at http://www.mydomain.com/Zope Zope does prompt me for a username and password. But it does not except my username and password (the one displayed after you ran the zope install script). I even tried to change the password with python zpasswd.py script. I still get the following error: Zope Error Zope has encountered an error while publishing this resource. Unauthorized You are not authorized to access this resource. Username and password are not correct. ______________________________________________________ Traceback (innermost last): File /usr/local/Zope2/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /usr/local/Zope2/lib/python/ZPublisher/Publish.py, line 179, in publish File /usr/local/Zope2/lib/python/ZPublisher/Publish.py, line 151, in publish File /usr/local/Zope2/lib/python/ZPublisher/BaseRequest.py, line 442, in traverse File /usr/local/Zope2/lib/python/ZPublisher/HTTPResponse.py, line 549, in unauthorized Unauthorized: (see above) Greetings Roché Compaan

DTML Scriptin Question
by Oliver Andrich 02 Oct '99

02 Oct '99

Hi, I use the following dtml code and it doesn't work as expected. <dtml-call loeschen_query> <dtml-var account> <dtml-if delete_emailonly> <dtml-in get_emailonly_query> <dtml-var account> <dtml-call loeschen_query> </dtml-in> </dtml-if> The code fragment is part of a dtml method which is used to submit some form data. Well, basically the works like that. The form has an inputfield account and checkbox delete_emailonly. On submission the SQL Method loeschen_query is called with the submitted argument account from the form. And this call works fine. Now a SQL method "get_emailonly_query" is called to get all emailonly accounts associated with the account submited in the form. This also works, cause in the "in-loop" all associated emailonly account names are printed as expected, but the calls to the SQL method don't work. But account has the correct value in this namespace I guess, cause the correct value is printed by the "<dtml-var account>" within the "in-loop". Can anybody help me? Or is there a way to see which SQL queries are actually called without enabling debbuging on the SQL Database? Best regards, Oliver Andrich

Since default is >inside of the instance, I believe you must have ZObjectManager as one of >the base classes. [I haven't tried it without ZObjectManager as a base >class, but I know it works when you do.] Good point. You do need to have ObjectManager as a base class. Thanks for summarizing like this... it makes it easier for other people until I get around to the HOWTO :) (the howto would probably be pretty similar to what you just wrote, but I'd probably also include the steps for the Defaults view).

Re: [Zope] html method called from html document?

Hi, -----Original Message----- From: Ainis <ainis(a)mindless.com> To: zope(a)zope.org <zope(a)zope.org> Date: Saturday, October 02, 1999 6:29 AM Subject: [Zope] html method called from html document? > Is this bug or feature- when i call html method from html document, >html method is treated as html document. For example I have an html method >called "standard_html_header" in which I have <dtml-tree... tag but it >shows up only when called from index_html method, but if my index_html is >Document tree does not show up :(. You may want to check out this doc: http://www.zope.org/Members/michel/HowTos/DTMLMethodsandDocsHowTo This describes the differences between Methods and Documents. Basically, a Method works within the namespace of its container. If an index_html Method calls standard_html_header to produce a tree, the container that the methods act upon is the Folder than contains index_html. Therefore, the tree lists the other objects available in the Folder. If index_html is a Document, then the standard_html_header operates with the Document as the container and would try to list other objects contained within the Document... That said, I still recommend reading over Michel's doc. Kevin
