sessions in an iframe
by henk laloli 14 Jun '06

Hello, I am using a session object to store a query string. The query string is used for a reload of the same query with two parameters changing their value when the user reorders a table column. This works fine under Zope 2.9.3 in Mozilla. The page on which this query string is stored en taken up again is in an iframe. The iframe html resides on a Zope server, the parents website's computer is a different one, but in the same domain. Now under Firefox the session object still can be referenced, but in Internet Explorer the page in the iframe does not reference the session object properly. It once records it and then adds the changing parameters to it,doubling them and making the SQL query run into an error. The url is: http://www.volkstellingen.nl/nl/gemeenten/ where after a search you can reorder table columns by clicking on the headers. The problem does not occur in IE when the page is used on its own, only when it is used in an iframe. The question then is: can it be that IE restricts the session behaviour in this situation? How can I solve it? Here is the code in a PythonScript, that is called in the search results html page. directionDict = {'gemeente':'gm_direction','provincie':'prov_direction', 'begindatum':'bd_direction','einddatum':'ed_direction','amsterdamse_code':'ac_direction'} if request.SESSION.has_key('firstquery'): if request.has_key('sort'): #user sorts column without a new query if request.richting == 'ASC': value = directionDict[request.sort] request.set(value, 'DESC') #put all other columns on ASC for k,v in directionDict.items(): if k != request.sort: request.set(v, 'ASC') else: value = directionDict[request.sort] #put all columns on ASC for v in directionDict.itervalues(): request.set(v, 'ASC') else: #user does a new query, session object exists del request.SESSION['firstquery'] query = request.QUERY_STRING first = request.SESSION['firstquery']=query for v in directionDict.itervalues(): request.set(v, 'ASC') else: #first query query = request.QUERY_STRING first = request.SESSION['firstquery']=query for v in directionDict.itervalues(): request.set(v, 'ASC') -- Henk Laloli

Zope will not allow access after IP address change
by Jeremiah Foster 14 Jun '06

14 Jun '06

Hello, I cannot seem to access the zope management interface on one of our machines after we moved it to another ISP. All the software is the same, the machine is the same, the only things changed are; 1. /etc/hosts 2. hostname 3. IP address Is there some security or other mechanism in zope that prevents zope from starting? Thanks, Jeremiah

Changing class of objects in the ZODB
by Miles Waller 12 Jun '06

12 Jun '06

Hi, Does anyone have a good approach to changing the class of an object already stored in the ZODB? A site is using classes defined and customised in a product on the filesystem, and I want to split the product into two to separate the unmodified vanilla product, and customisations. I found a script from shane when I googled which purported to do this, but I did not understand exactly what it did and so am a bit nervous of using it. Also, it appeared to do it all in one transaction, which would not be practical for this site (too many objects). I had originally been envisaging doing something in __getstate__ for these objects, so when they were retrieved, they were updated and marked as having been changed so they would be committed at the end of the transaction. But I don't really know exactly what! I don't think it will work to use module_aliases because there will still be a class that can be imported from the original location. Any help much appreciated, Miles

RE: [Zope] Changing class of objects in the ZODB
by Doyon, Jean-Francois 12 Jun '06

Assuming you're not changing attribute values, but *just* the class, I've had success with doing an XML export, a find/replace of the class name, and a re-import. The XML is fairly readable, you can just look for example for "Products.MyProduct.OldClass" and replace it with "Products.MyProduct.NewClass".
