newbie question: Redirect from Python?
by Paul Winkler 28 Nov '00

28 Nov '00

I want the user to be sent to a particular URL after calling the product's manage_add method. How can I do that? The URL I want is REQUEST['URL3']. I've tried RESPONSE.redirect(REQUEST['URL3']) but that's not it - the RESPONSE doesn't seem to exist here. -- ................. paul winkler .................. slinkP arts: music, sound, illustration, design, etc. web page: http://www.slinkp.com A member of ARMS: http://www.reacharms.com

I hope, you do not need the redirect in your constructor as in the constructor the newly created object is not yet tied into the web site hierarchy via acquisition. If the object, say "self", is already tied in, then you can use "self.REQUEST.RESPONSE.redirect(....)". If you need it in the constructor, then you must either pass in an object that is tied by acquisition or REQUEST or RESPONSE itself, or you must move the call out into the method "manage_afterAdd" (where the object already is tied in).

When I remember right, the Add box is constructed by "filtered_meta_types". Thus, you must give your ZClass a method with this name (the correct name, if I do not remember right), that returns the correct list. Dieter

A user folder is only allowed to return "Annonymous", if it is the top level user folder. Thus, your "/sms/shtml/statios/acl_users" must return "None" and ZPublisher should ask "/sms/acl_users" which should return "Operator". > Another investigation: I am logged as operator in a new browser and have the > problem, I click on a link for a stationx user but cancel the http > authentication, then the problem disappear. Hmmh, the only difference should be that you no longer have an HTTP authentication. I do not understand this behaviour. > Is there a way to display which object has triggered the authentication, and > which acl_users folder is used?? You can instrument the code in "ZPublisher.BaseRequest.traverse" to output this information. Dieter

client argument to python function calls?
by Randall Kern 27 Nov '00

27 Nov '00

I'm trying to emulate some DTML methods with python code in my (python) product. Let's say I have two Python classes, one named Foo, the other Bar. Something like this: class Foo(Folder.Folder, Persistent, Implicit): meta_type = "Foo" def magic(self, client=None): "magic method!" if client == None: client = self return client.magic_word class Bar(Folder.Folder, Persistent, Implicit): meta_type = "Bar" def __init__(self, id): self.id = id self.magic_word = 'Alacazam!" Now I create a structure like this in Zope: / foo (instance of the Foo class) bar (instance of the Bar class) Now if I goto /bar/foo/magic, I see the magic word. However, I would also like to use /foo/bar/magic, and also receive the magic word. This latter case doesn't work, the magic_word isn't set. In fact, the "client" argument is never anything but None. This is a facet of Zope I still don't quite understand... Thanks, -Randy

Re: [Zope] getattr in Python Method problem

Anyway, there are several Python method implementations around that might be different in the relevant aspects. Personnally, I would expect a bug in "getattr". However, it might also be the case, that "self" is not what we expect (and what it is for external methods: the folder, the object is located in). If you use a new version of Python Methods (now called Python Scripts), then you might try "context" rather than "self". I think, you can use it without the need to pass it as parameter. Dieter
