The folder attribute can be acquired, which means if for example can be a script in a skin folder, or it can be something you monkey-patch to the folder. Or it can be calculated, or it can be a view (I think) etc, etc. //Lennart

Re: [Zope] Problem Understanding URL

Tres, I see what you mean. You're saying that the object lookup for a request follows a pattern and that the __getitem__ function has a role in that pattern. That's fine, but even if this is returning a User object there is still a problem. I think we're beyond the point where you can help me though. The problem I'm thinking of is that I know that the /Users/asmithS URL resolves to a call to index_html method of Users which in this case is just rendering the "userView". As I've said the here/Property calls are located in this user view. Could this __getitem__ load the user into the context and then still call the index_html and return the .zpt? Thanks

Ok I'd read about those functions a little bit in the Zope 2 book or the Developer's Guide, but they seemed like advanced techniques that I probably wouldn't need to understand. Back on topic; I ran this awesome command in the terminal: grep getitem x=$(find . *.*) and turned up some random references to getitem in some dtml code, which I judge to be insignificant. There was also one very interesting usage of __getitem__ in the python code itself, and I have to investigate the code further to understand what's going on. The function definition looks suspiciously like what I would expect to find for this 'hijacking' of control: def __getitem__(self, key): v=self._getOb(key, None) if v is not None: return v if hasattr(self, 'REQUEST'): request=self.REQUEST method=request.get('REQUEST_METHOD', 'GET') if request.maybe_webdav_client and not method in ('GET', 'POST'): return NullResource(self, key, request).__of__(self) raise KeyError, key I read this as: look up the object in the current context and return it. The only problem with this is that I don't see when the object gets placed into the proper context for the TAL statements like here/FirstName, etc. Thanks for your help already, and any continued guidance is appreciated.

Problem Understanding URL
by Jared Hall 23 Jul '12

23 Jul '12

I think I have a simple question about how Zope is handling requests. My current task is to understand an already-written Zope web application. One thing I can't wrap my head around is this URL: https://mysite.com/UserManagement/Users/asmithS/ Speaking in Zope terms, the UserManagement object is contained in the top-level product. In the UserManagement object, there is a Users object. That's all fine and dandy, run of the mill, acquisition/containment. However, the Users object has no asmithS object. In fact, asmithS is just a username, which makes the last field in the URL essentially a parmeter on the Users object. >From examining the behavior of the webapp and the code itself, I know that the index_html method of the Users object is what is returned from this request, which is a Page Template that displays the user information based on the parameter. All of what I've said so far could be wrong, so feel free to correct me if I've mis-spoken. The problem I have is that this asmithS guy seems magical. I can't figure out how the index_html knows to be called with the username as a parameter(obviously the index_html function doesn't explicitly require the parameter). What I BELIEVE is happening: the asmithS argument is processed before the page template renders. For example, when asmithS is given, a lookup is performed on the database that adds variables to the REQUEST object such as FirstName, LastName, etc. I can't find this happening but I think it must exist. >From the zpt file: <td valign="top" tal:content="here/LastName">Doe</td> What I want to know is: How can do these URL arguments work? A more advanced question would be: how do you think these here/*** variables are being added to the context. I'm actually using Zope 2. Thanks for any help

Hello, I have a python script in my zope instance: dt=DateTime(2012,1) print dt print dt.strftime('%Y') print dt.year() return printed 2012/01/01 00:00:00 GMT+2 2011 2012 Why do I get two different values for the year (2011, 2012)? Thank you, Giampiero

Python scripts

Hi On Zope 2.10 is there a simple/universal way to only allow python scripts to be called by DTML methods or other python scripts and not directly TTW? Thanks Rich

Sessioning
by Richard Harley 23 May '12

23 May '12

Does anyone have a recommendation on how to implement sessioning on Zope 2? Basically to set browser timeouts for the user so logout after say 20 mins of inactivity. The difficulty we've had previously is detecting what exactly 'inactivity' is... Cheers Rich

Unexpected behavior with zope.session 3.9.5
by Chris Austin 11 Apr '12

11 Apr '12

Hi List, I'm running into an bit of a problem implementing zope.session on Zope2-2.12.10. When running the following code inside a class that inherits from BrowserView: session = ISession(self.request)[product_id] I get the following error. AttributeError: ZServerHTTPResponse instance has no attribute 'getCookie' Looking through the zope.session code, the Session object adapts IRequest. The exception is being thrown in zope.session.http.CookieClientIdManager in the the getRequestId() method with the following code. def getRequestId(self, request): '''....''' response_cookie = request.response.getCookie(self.namespace) I am not sure where to begin tracking this down. Could this be an error with utility lookup?
