Zope Recordset Object
by Alric Aneron 16 Jun '06

16 Jun '06

Hello, I have a ZSQL Method, which is called by my python script. However, I am curious as to what type of object is returned when that call is made. It's some sort of a recordset (or resultset) object that behaves like a list...it doesn't seem to be a dictionary object though, but I can't find any object reference on it. I tried using rs.keys() but it says that method doesn't exist in that class. Does anyone have a member function list (object reference ) that's associated with this resultset or can tell me what kind of object is returned? I gave up on google, couldn't find anything on it. Thank you in advance! __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com

Efficiency of "Script (Python)" versus External Method
by Andrew Hedges 16 Jun '06

16 Jun '06

Is there a difference in the efficiency of a function as a "Script (Python)" Zope object versus an External Method? The use case is that I need to run a fairly simple function (an implementation of the Levenshtein distance algorithm) over a result set in the range of 30-40k records. Are the two implementations close enough that I should just not worry about it or would you expect I would see a significant difference between the two? Thanks, -Andrew ----- andrew(a)clearwired.com / http://clearwired.com

allow access to fileobject depending on role
by leandros van den berg 15 Jun '06

15 Jun '06

Hello, I'm having trouble with the precondition field of a fileobject. I've got a fileobject (a PDF-file) and its precondition field states myPrecondition, which is a DTML Method and its code is: <dtml-with "REQUEST['PARENTS'][0]"> <dtml-if expr="_.SecurityGetUser().has_role(['Bobo']) != 1"> <dtml-raise Unauthorized></dtml-raise> </dtml-if> </dtml-with> (source: http://www.zopelabs.com/cookbook/1016369692) The PDF-file should only be displayed when an user has role Bobo. If the user doesn't have the role, an user authentication screen (login screen) is displayed. The Method only works when the browser cache is empty or the file hasn't been openend yet by an user with Bobo-role. I'll explain the situations, both are on localhost. Situation I: - Browser cache is empty. - User without Bobo-role logs in and opens the PDF-file by entering its URL in the browser and gets the login screen. So far so good. Situation II: - User with Bobo-role logs in and opens the PDF-file by entering its URL in the browser and the file is being displayed. - Close browser. - User without Bobo-role logs in and opens the PDF-file by entering its URL in the browser and the file is being displayed. Not so good. The user without Bobo-role in situation II should get a login screen. Apparently because the file is in the browser cache, the user is authenticated. Does anybody know a solution to this problem or some other solution for allowing access to a fileobject depending on the role an user has? Note: Using the security setting and assigning roles is not an option because the fileobject is recreated every night. Kind regards, Leandros -- The Netherlands

I specified the full > path just to make sure. :) Did you use python 2.3 or python 2.3.4 (or 2.3.5)? This may make a difference. Is the ZMySQLDA product installed ok? Check the icon in the ZMI - Control Panel - Product Management folder (it should not show a broken product icon). You can also check the ZMI - Add list, there should be a 'Z MySQL Database Connection' entry in the list. Jonathan

sessions in an iframe
by henk laloli 14 Jun '06

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
