You need to go into the Storage tab of your UserSource (in acl_users, click the UserSource tab, then click on the only UserSource, then click on the Storage tab). Then select your new ZClass as the "Class to use for stored items" and set "Objects are:" to "loaded by accessing attribute" 'member_id'. Thanks for the bug report! I'll add this to the HOWTO soon.

Python script / python method problem
by Lothar T.E.L. 04 Jan '01

04 Jan '01

Hello! I am having a problem with one of the examples in Chapter 12 of the Zope book. I am creating a new product called "Zoo Exhibit" comprising of a DTML method, a Python script and, of course, a factory. http://www.zope.org/Members/michel/ZB/CustomZopeObjects.html < just under Fig 12.2 details the example. I have a DTML method sending "id" and "title" to a Python method/script. I am told to create a "Python Script". I assume this is done by creating a "Python Method"? This is the script I am told to create: def add(self, container, id, title, REQUEST=None): """ Copy the exhibit template to the calling folder. """ exhibit=self.manage_clone(container.exhibitTemplate, id) exhibit.manage_changeProperties(title=title) if REQUEST is not None: return self.manage_main(self, REQUEST) Should this be the entire body of the method or do the parameters need to be listed AGAIN in the "parameter list"? When I add my new Zoo Exhibit product it calls the DTML method and I can insert the data as required but when submitted it does not do ANYTHING. What I am asking is: Exactly what is added to the parameter list, method body & title of the newly created Python method? Thanks in advance! _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com

Problem with SiteAccess
by Leonardo Graf 04 Jan '01

04 Jan '01

Hello, I'm trying to use the SiteAccess Product as discribed in the HowTo: Using Apache with ZServer (NOT Zope.cgi). Unforunately things don't work as described. My ZServer is listening on www.myserver.com:9080/somesite. I would like to be able to access the ZServer through apache via the URL www.somesite.com (to do virtual hosting). The ProxyPass directives work well (the pages get served properly), but the URL's in my pages still contain the complete URL's of the ZServer, like <img src="http://www.myserver.com:9080/somesite/images/some.gif"> instead of <img src="http://www.somesite.com/images/some.gif">. The same is true for normal links. Ok, it's not so bad, things work (no broken links), but it is a little bit ugly. I thought the SiteAccess Product should handle these problems, by putting a SiteRoot object in the somesite folder. Or do I have to write an AccessRule ? And how would that look like ? Thanks a lot, regards, Leonardo Graf

WIN2k batch problem
by Robin Becker 04 Jan '01

04 Jan '01

I'm trying to run Zope 2.2.2 under win2000 in a batch file. I'm just watching error messages and prints. I find that when zope has written a page to the cmd.exe window it locks further prints from python until I hit a key in the window and then it releases another page full. Is there a Win NT/2K guru who knows about such things and how to prevent this? -- Robin Becker

Zope redirecting manage_workspace?!
by Edmund Goppelt 04 Jan '01

04 Jan '01

I've created a simple news item ZClass. When I attempt to manage a News Item instance, I get the default view (or whatever happens to be the first method listed in the ZClass 'Views' tab) instead of the usual management interface with properties, undo, view etc. Sniffing the http conversation shows that the folder's management interface is calling manage_workspace on the news item as it should, but that Zope is redirecting the web browser to index_html. Why is this happening and how do I fix it? Here's what happens when I click on the instance in the management screen: GET /Z/testfolder/manage_main HTTP/1.0 Referer: http://www.xyz.org/Z/testfolder/manage_main Connection: Keep-Alive User-Agent: Mozilla/4.75 [en] (X11; U; Linux 2.2.16-3 i686) Host: www.spado.org Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, image/png, */* Accept-Encoding: gzip Accept-Language: en Accept-Charset: iso-8859-1,*,utf-8 Authorization: Basic Z29wcGVsdDpibG9ydDJ1 Cookie: tree-s="eJyLjlZ3hAKX8kBbdR2F6NjYWABEjQYU"; tree-s="eJyLjlZ3hANPW/XYWAAtiQTP"; dtpref_rows="20"; dtpref_cols="75" HTTP/1.0 200 OK Server: Zope/Zope 2.2.2 (source release, python 1.5.2, linux2) ZServer/1.1b1 Date: Thu, 04 Jan 2001 16:04:01 GMT Connection: Keep-Alive Content-Type: text/html Content-Length: 12486 ...Bunch of stuff deleted <TR> <TD ALIGN="LEFT" VALIGN="TOP" WIDTH="16"> <INPUT TYPE="CHECKBOX" NAME="ids:list" VALUE="computer"> </TD> <TD ALIGN="LEFT" VALIGN="TOP"> </TD> <TD ALIGN="LEFT" VALIGN="TOP"> <A HREF="computer/manage_workspace"> computer (My Computer Title) </A> </TD> </TR> So my client asks Zope to manage_workspace the news item...

RE: [Zope] Using a multiple_selection property in a product
by Randall F. Kern 04 Jan '01

Try this: _properties = (.... {'id':'classdays', 'type':'multiple selection','mode':'w', 'select_variable': 'days'}, ...) days = ( 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday' ) -Randy -----Original Message----- From: Ronald L. Roeber [mailto:rroeber1@unl.edu] Sent: Wednesday, January 03, 2001 2:48 PM To: zope(a)zope.org Subject: [Zope] Using a multiple_selection property in a product I am attempting to build a product that will contain some unique information and access control for services in support of college classes. Many, many things are going well...better than expected. However I am having problems getting the product to correctly recognize a multiple selection property. The property is the days of the week that the course is offered. ( Monday-Wednesday-Friday or Tuesday-Thursday, or any combination thereof) The DTML for the product creation form contains the following: --- <th align="LEFT" valign="TOP"><em>Days Course Offered</em></th> <td align="LEFT" valign="TOP"> <select name="classdays:multiple_selection" size=5 multiple> <option value="Monday">Monday</option> <option value="Tuesday">Tuesday</option> <option value="Wednesday">Wednesday</option> <option value="Thursday">Thursday</option> <option value="Friday">Friday</option> </select> ---- in the product class I have tried two tactics (actually more but I'll confess to only these two) _properties(.... {'id':'classdays', 'type':'multiple_selection','mode':'w'}, ... RESULT: product installs, but classdays in an "unknown property type" so I try this: _properties(.... {'id':'classdays', 'type':'multiple selection','mode':'w'}, ...

manage_addFile problem
by Ian Sealy 04 Jan '01

04 Jan '01

Dear all, I've got a really simple little Zope application that allows staff here to upload documents into a folder of their choice without seeing the Zope management screens. There's a form that looks like this: <form action="admin_addfiles" method="POST" enctype="multipart/form-data"> <input type="file" name="file" size="40"> etc... The admin_addfiles method then actually creates the file and applies some properties to it (that also come from the form): <dtml-call expr="manage_addFile(filename, file=file, title=filetitle)"> <dtml-let newfile="_.getitem(filename)"> <dtml-call expr="newfile.manage_addProperty('author', fileauthor, 'string')"> <dtml-call expr="newfile.manage_addProperty('maintainer', filemaintainer, 'string')"> <dtml-call expr="newfile.manage_addProperty('description', filedescription, 'string')"> </dtml-let> It all works fine until I try to upload a file that's greater than about 128 kb. When I try that I get the following error: Error Type: AttributeError Error Value: abort_sub Traceback (innermost last): File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 222, in publish_module File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 187, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 221, in zpublisher_exception_hook (Object: Traversable) File /usr/local/zope/lib/python/ZPublisher/Publish.py, line 175, in publish File /usr/local/zope/lib/python/Zope/__init__.py, line 235, in commit File /usr/local/zope/lib/python/ZODB/Transaction.py, line 290, in commit AttributeError: (see above) I don't see this if I add a similar-sized file using the Zope management screens. Anyone done anything similar and seen this? Cheers, Ian -- Dr Ian Sealy Internet Development Institute for Learning and Research Technology University of Bristol

Question on __roles__
by cg＠cdegroot.com 04 Jan '01

04 Jan '01

I have encapsulated most bits of my software in a product. One part simply shows database objects, and I've made a base class to handle most of the showing and editing stuff. In the base class, I keep a tab on what methods etc. are used for viewing and for editing, and I use these in the concrete classes to set the roles. Eg: Base.py: class Obj(OFS.SimpleItem.Item, Acquisition.Implicit, AccessControl.Role.RoleManager, AccessControl.Owned.Owned): view_objects = [] index_html = HTMLFile('default_view', globals()) view_object.append('index_html') ... etcetera Customer.py: class Obj(Base.Obj): __ac_permissions__ = ( ('View Own Info', Base.Obj.view_objects), ) ... Globals.default__class_init__(Obj) As far as I can see, this is all by the book. The whole idea is that the set of methods is the same, but the permissions on them can differ (for example, there are special restrictions on viewing and editing invoices). However, these protections don't work in most cases. They seem to work when they pertain to methods, but they don't when they pertain to DTML files. Is there something in the base class' base classes that influences how role lookup works? I've tried to trace down what happens, and found that ZPublisher.BaseRequest has a funny bit: when trying to find out the necessary roles on an object, it first tries to get the attribute '__roles__' on the subobject, and then combines the current entry name plus '__roles__' and tries to get that from the subobject. However, it seems to me that the latter getattr() needs to be done on the object, not the subobject - at least, my tracing seems to indicate that if it walks down, say 'Customer/53/index_html', that at a certain moment during the traversal object = <Customer instance> subobject = <Python method> entry_name = 'index_html' Here, looking up "index_html__roles__" in the subobject, the index_html method, doesn't seem to be very useful - it is expected to be found on the containing Customer instance. And indeed, if I change line 386 in BaseRequest.py from: roles = getattr(subobject, entry_name+'__roles__', roles) to: roles = getattr(object, entry_name+'__roles__', roles) things work as I expect them to work. As this is such a core piece of Zope, it seems quite unlikely to me that I found a bug here (although an older version of ZPublisher does check object instead of subobject). The only thing I can think of is that Acquisition should work for the getattr() and somehow I managed to disable Acquisition on these instances. Any hints as to what I'm doing wrong? -- Cees de Groot http://www.cdegroot.com <cg(a)cdegroot.com> GnuPG 1024D/E0989E8B 0016 F679 F38D 5946 4ECD 1986 F303 937F E098 9E8B
