Zope 2.5.0b4 trouble
by Oleg Broytmann 26 Jan '02

26 Jan '02

Hi! I just installed 2.5.0b4 and tried to import my sites. One site works fine, but the other give an error on almost all requests. What's that? Error Type: KeyError Error Value: meta_index Traceback (innermost last): File /usr/local/Zope-2.5.0b4-src/lib/python/ZPublisher/Publish.py, line 150, in publish_module File /usr/local/Zope-2.5.0b4-src/lib/python/ZPublisher/Publish.py, line 114, in publish File /usr/local/Zope-2.5.0b4-src/lib/python/Zope/__init__.py, line 158, in zpublisher_exception_hook (Object: zope.net.ru) File /usr/local/Zope-2.5.0b4-src/lib/python/ZPublisher/Publish.py, line 98, in publish File /usr/local/Zope-2.5.0b4-src/lib/python/ZPublisher/mapply.py, line 88, in mapply (Object: index_html) File /usr/local/Zope-2.5.0b4-src/lib/python/ZPublisher/Publish.py, line 39, in call_object (Object: index_html) File /usr/local/Zope-2.5.0b4-src/lib/python/OFS/DTMLMethod.py, line 127, in __call__ (Object: index_html) File /usr/local/Zope-2.5.0b4-src/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: index_html) File /usr/local/Zope-2.5.0b4-src/lib/python/DocumentTemplate/DT_With.py, line 76, in render (Object: Python) File /usr/local/Zope-2.5.0b4-src/lib/python/OFS/DTMLDocument.py, line 120, in __call__ (Object: python_news_short) File /usr/local/Zope-2.5.0b4-src/lib/python/DocumentTemplate/DT_String.py, line 473, in __call__ (Object: python_news_short) File /usr/local/Zope-2.5.0b4-src/lib/python/DocumentTemplate/DT_With.py, line 76, in render (Object: Python.News.parnassus_news) File /usr/local/Zope-2.5.0b4-src/lib/python/DocumentTemplate/DT_Util.py, line 159, in eval (Object: _['meta_index']=='') (Info: _) File <string>, line 2, in f File /usr/local/Zope-2.5.0b4-src/lib/python/AccessControl/DTML.py, line 32, in guarded_getitem (Object: index_html) File /usr/local/Zope-2.5.0b4-src/lib/python/AccessControl/ZopeGuards.py, line 90, in guarded_getitem KeyError: (see above) Oleg. -- Oleg Broytmann http://www.zope.org/Members/phd/ phd(a)phd.pp.ru Programmers don't die, they just GOSUB without RETURN.

How to keep an object in the zodb cache?
by Gregory Popovitch 26 Jan '02

26 Jan '02

Hi, I am writing a product which loads a large python structure object from disk. I don't wish to store this structure in the Zope Zodb, so I load it in a variable prefixed with _v_. The code looks like: class myproduct(SimpleItem.SimpleItem): def __init__(self, id, title): " initializes a new instance of a myproduct" self.id = id self.title = title self._v_store = None def load(self): " load store into memory " import mystore if not hasattr(self, '_v_store') or not self._v_store: print "loading store" self._v_store = mystore.LoadStore(self.title) The function self.load() is called from each URL method to ensure that the store is loaded. My problem is that after some inactivity in the web server, I can see that the store is reloaded when a web page is requested, and it takes some time. I assume that the object self._v_store has been flushed from the zodb cache and discarded. How can I prevent self._v_store from ever beeing flushed from the cache? Any idea? Thanks, Gregory Popovitch

Python Product Coding Guidelines? (constructor=...)
by Thomas Guettler 25 Jan '02

25 Jan '02

Hi! When I "grep" for the constructor syntax in the __init__.py files I see that most people use the form constructor(manage_addFoo, ...) The DevGuide just calls the function addForm. I think it would be good if there would be a guideline. This makes it easier to read other peoples code. What do you think?

basic search engine (product?) for a working website in zope
by cruciatuz 25 Jan '02

25 Jan '02

i integrated a website in zope (uploaded the complete site with ftp and splitted navigation into one single file, which is dynamically inserted in every single page with dtml-var, and did some other things ...). BUT: now i want to add a simple search-form in the file with the navigation which outputs the search-results on a new page with hyperlinks, like many modern websites do (it's called a "site search", i think). i didn't find a product which can do that AND i am not able to code this thing myself (i played around with zcatalog, but it's a very complex thing and my book about zope doesn't tell how to code a site search, it just says what i 'could' do with a zcatalog). i also had a look at cmf, but i wont be able to use it with the zope installation at work. any suggestions? any products i missed? a tutorial which discribes how to solve my problem? some hints? -- many thx in advance Stefan Antoni ---------------------------- Fre Jan 25 17:53:46 EST 2002

Newbie Unable to Login to Management Interface on RH 7.2
by CLIFFORD ILKAY 25 Jan '02

25 Jan '02

Hi, I just installed Zope 2.4.3 onto Red Hat 7.2 from the RPMs that I found at <http://www.taupro.com/Downloads/Zope/Zope243> and followed the directions on that site. I elected to use Zope.cgi so that I could continue using Apache. I had to change all references to /var/www from /home/http but other than that, no problems. I can see the Zope welcome page and browse the on-line docs but I cannot login when I browse to <http://localhost/manage>. Since I was not absolutely certain what the default superuser password was out of the box, I changed it by executing the following: # /usr/bin/python /usr/share/zope/utilities/zpasswd.py /var/zope/access After I changed the password, I restarted both Apache and Zope to no avail. I ran the password program again and set the password to CLEARTEXT to ensure I had it right, restarted both Apache and Zope, and again, no luck. There is nothing obvious in the Zope and the Apache logs. Any ideas?

problem with security
by Robert Rottermann 25 Jan '02

25 Jan '02

Hi there, I have a script that is called TTW by anonymous. Its job is to copy a folder that is in one of its parent folders. The script has "Manager" as proxy role. When it is trying to paste the folder it gets a security assertion saying that it is not allowed to do so. When I give anonymous the right "create folder" every thing works fine. Why is that so??

Problems with setting Local Managers
by Agata Cruickshank 25 Jan '02

25 Jan '02

I am a zope 'newbee' and would really appreciate if someone could help me. I am trying to set up a manager on a sub-folder 'Sales' in Sales/acl_users folder, but when I try to log on http://mydomain.com:8888/../../Sales/manage and enter the password in the prompt box I do get unauthorised error (I can get in by entering the password of the manager whose details are stored under root/acl_users folder. I don't get this error on a local installation of Zope, so I assume it has something to do with the way Zope is installed on the server. I run Zope 2.4.3 binary release on sunos5 operating system, with Apache front end connected via PCGI. It runs on 8888 port. It seems that Zope cannot find a path to acl_user folder in any subfolder, and only manages to get to acl_users under Root Folder. Any suggestions? Many thanks, Agata

Error messages not being displayed by proxy
by Smith, Neil 25 Jan '02

25 Jan '02

We are running Webthority to secure access to our server. It works fine except that if there is an error, then instead of getting the error message from Zope, we get an error screen from the proxy. i.e: Webthority Error: Unable to retrieve content at this time. Please contact your administrator if this problem persists Error 503 from server I guess that this is because Zope sets something in the header to say that it is an error rather than just normal html, which the proxy intercepts. Is this the case, and if so, is it possible to set something so that errors get displayed as normal html pages?

Help on __before_publishing_traverse__.
by Sidnei da Silva 25 Jan '02

25 Jan '02

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hello everyone. Im developing a product in python that does some content management functions, and one of the features I`m trying to implement is to make the content public based on some properties, so, i`ve add the following code to my product: def __before_publishing_traverse__(self, REQUEST=None, *args, **kw): if hasattr(self, 'data_inicial') and hasattr(self, 'data_final'): if (DateTime.DateTime(self.data_inicial).ISO() < DateTime.DateTime().ISO()) \ and (DateTime.DateTime(self.data_final).ISO() > DateTime.DateTime().ISO()) \ and self.getStatus()=='publicado': self.manage_permission(permission_to_manage='View', roles=[], acquire=1, REQUEST=None) self.manage_permission(permission_to_manage='Access contents information', roles=[], acquire=1, REQUEST=None) else: self.manage_permission(permission_to_manage='View', roles=['Manager'], acquire=0, REQUEST=None) self.manage_permission(permission_to_manage='Access contents information', roles=['Manager'], acquire=0, REQUEST=None) My doubt is: This code works OK for the view property. When a user tries to access the page, and the date range is outside the permitted range, it gets a login screen. But then is the following problem: I have a dtml-in that lists the documents inside this folder, and i want it not to list the document which is outside the range. But i want to do this based on the permission. For what i know, the permission to access the properties of the document is "Access content information". But the strange thing is that the __before_publishing_traverse__ code is run, the permissions are set ok but the document keeps listing, except when i click the security tab. Then, suddenly the document isnt listed anymore. I think that im missing some operation that the security tab performs to make the permissions begin to work. Can anybody help me? Anyone know of a method that gets accessed when i access a property, so i can hook my code on the right place?? Excuse me for writing a book, but i wanted to keep it clear.
