OFS/Image.py strange error
by Vladimir Petrovic 08 Oct '03

08 Oct '03

Hi, I'm getting a very strange error during the development of my python based product. The error occurs only in one specific case, and the setup is quite complicated. The error happens inside Zope code, so I'm looking for hints how to proceed with debuging. The issue is that during a call to _read_data () in OFS/Image.py I get the following error: KeyError: validate Traceback: Module ZPublisher.Publish, line 98, in publish Module ZPublisher.mapply, line 88, in mapply Module ZPublisher.Publish, line 39, in call_object Module OFS.DTMLMethod, line 135, in __call__ However, the actual _read_data () happens inside the python product, so the original traceback is somehow lost. Here is the setup: I have a python product which defines a class that inherits ObjectManager (called Content). I have another classes DRFile/DRImage which inherit Zope's File/Image. Inside manage_addContent (), manage_addDRFIle () is called to create automatically new DRFile inside content: manage_addContent (): co = Content (id) self._setObject (id, co) co = self._getOb (id) co.add_part_web (default_part_id, default_part) add_part_web (pid, pdata): nid, title = get_default_id_title_for_file (pid, '', pdata) manage_addDRFile (self, id=nid, title=title, file=pdata) manage_addDRFile (): o = DRFile (id, title, '') self._setObject (id, o) if file: o = self._getOb (id) file_upload (o, file) Now file_upload (o, file) is the problem. It used to contain just: obj.manage_upload (file) But this line was generating the error. If I put raise 'ABC' just before, I get the 'ABC' exception, but if I put it just after I get this KeyError. I've managed to avoid this exception with: file_str = file.read () data, size = obj._read_data (file_str) content_type = obj._get_content_type (file, data, obj.__name__, 'application/octet-stream') obj.update_data (data, content_type, size) This is exactly the code from mange_upload () from Image.py, except string is passed (file.read ()) to _read_data () instead of actual FileUpload object. This error happens only in one specific case. I can upload the file manually through Zope management interface. I can also upload many other files without any problem. I could imagine something is wrong with FileUpload object, but I don't know how to proceed with the debugging because I don't know how it is possible that _read_data () produces the traceback which doesn't have anything in common with the way it is called ? Thanks in advance, Vladimir

Problem with programmatically adding users to acl_users
by Ruth Mizzi 08 Oct '03

08 Oct '03

Hi, I've just created a little dtml script to carry out user registratin... when a user fills in the form he should be added as a site user and thus added to acl_users. The structure I got is the following /Zope Root Folder / Parent Folder / acl_users / Registration folder - registerForm.html - registerAction.dtml The dtml method is one I've found listed on loads of sites .... <h2>User Registration</h2> <dtml-call "REQUEST.set('username', '<username>')"> <dtml-call "REQUEST.set('password', '<password>')"> <dtml-call "REQUEST.set('confirm', '<confirm>')"> <dtml-call "REQUEST.set('roles', ['Member'])"> <dtml-call "REQUEST.set('domains', ['Domain1'])"> <dtml-call "REQUEST.set('submit', 'Add')"> <dtml-call "acl_users.manage_users(submit='Add', REQUEST=REQUEST)"> I'm getting no errors reported but also I'm getting no user created in the folder... what's going wrong?

POSKeyError when registering new user via ZMC
by Ruth Mizzi 08 Oct '03

08 Oct '03

I've currently got Zope-2.6.2 running on linux and have just tried to install the latest version of ZMC (Membership Manager). I've managed to get it running after solving a few problems such as removing the self parameter from methods such as the passwordPolicy script etc.... Now I've got this one problem that I just can't solve... I've found loads of postings on forums about similar PosKey problems but can't seem to find anything that matches my particular case. All I'm doing is trying to register a new user by using the joinForm.... I add the new user name and password and click on Register and keep getting ... Zope has encountered an error while publishing this resource.

explicit object reference without acquisition
by Brad Dickerson 08 Oct '03

08 Oct '03

I would like to call an Zope object (and pass variables to it) located in a folder that is not reachable by acquisition from a DTML method. When I tried the following it failed: E.g. If I have a dtml method in the folder "/a/b" called index_html. Inside of this dtml method I have the following statement <dtml-var expr="c.d.e.(var1='var1')"> The Zope folder object "/c/d/e" exists and has a DTML method inside it called index_html that references the variable var1. When I try to evaluate the above expression, I get the following error: Error Type: AttributeError Error Value: __call__ What am I doing wrong? I would like to make use of objects inside of Zope that are not reachable by acquisition via the <dtml-var>' or <dtml-call>' methods.

Filesystem Directory View, etc.
by Aurélien Campéas 07 Oct '03

07 Oct '03

Hi all, I'm trying to get some Webalizer stats accessible from a Zope instance. The problem is FSDV transforms any .html .htm .dtml document (it just rips the extension). I don't know why it does that, nor how I could tell FSDV not to do it, but it's a little rude since Webalizer builds many html pages that are linked together according to their full names (name+ext). So the navigation from imported Webalizer pages into FSDV is broken. Also note that while it's possible to tell Webalizer to produce various extension names for the files it builds, I don't see how to tell him NOT to produce any. Anyone has an idea how to proceed ? Thanks, Aurélien.

Calling methods on products
by Richard Jennings 07 Oct '03

07 Oct '03

Help! I have a Zcatalog in which I can add actors successfully. I can also add a product for serving sequential tokens. My intent is to use the tokens to id the actors in the actor constructor. My problem is that I don't know how to get the constructor to call the getToken() method on the token generator. I thought container.generator.getToken() should do it but I get a keyError saying non-existent 'generator.getToken'. The generator is subclassed from SimpleItem and also Acquisition.Implicit. Can someone tell me where I'm going wrong? TIA Richard Jennings
