Getting single values out of lists
by Borno Janekovic 08 Aug '00

08 Aug '00

Hi, I have a page wich is created out of a database. For every artikel (item) I have a description and a number of available items. The page has multiple rows (depending on the database content) in every row is a input-box in wich the user can enter a number. This number needs to be substracted from the available items number of the correct artikel. My question is how can I get the correct tuple of items out of the list. For example In every row I have the substract box and a hidden field with the primary key: <input type="text" size=5 value="" name=substract> <input type="hidden" value="<dtml-var artikel_id>" name="artikel_id"> When I submit the Form I get with the following lines <dtml-in "REQUEST.form.items()" sort> <dtml-var sequence-key>:<dtml-var sequence-item><br> </dtm-in> the content substract = ['12', '', '', '', '', '', '', '', '', ''] artikel_id = ['20000808095658', '20000808095503', '20000808095341', '20000808095744', '20000731135126', '20000808092056', '20000808092333', '20000808092723', '20000808095232', '200007311227'] and this is correct. This means that a user has entered 12 for the artikel_id 20000808095658. How can I get the single values, so that I can use them? How can I extract the values from the list to use the tuple in a sql-statement? Help would be great. Thanxs Borno -- Sent through GMX FreeMail - http://www.gmx.net

ZClass property that is a map
by Scott Brodsky 08 Aug '00

08 Aug '00

It's my understanding that this can only be done in python in the Products subfolder. I did something like this with David Murray's help for a BannerProduct. I modified an existing python-based banner class and added two "maps" to each banner object called 'history_views' and 'history_clicks' indexed by a date. Here's part of code I'm using: in /Products/ Ban.py file: __doc__="""Ban Ad Classes""" __version__=0.1 from Globals import HTMLFile from Globals import MessageDialog from Globals import Persistent from OFS.Image import Image #import OFS.Image import OFS.ObjectManager import Acquisition # Various acquisition types. import AccessControl.Role # Zope Security management. import string class Ban: " A Ban Ad Class" meta_type="Banner Base Class" def __init__(self,id,title,file,content_type='',precondition=''): self.history_clicks = {} self.history_views = {} def __setstate__(self,state): Persistent.__setstate__(self,state) if not hasattr(self,'history_views'): self.history_views = {} if not hasattr(self,'history_clicks'): self.history_clicks= {} later in the code the history_views map is updated when a banner ad is viewed: keydate=time.strftime("%y%m%d",time.localtime(time.time())) if self.history_views.has_key(keydate): self.history_views[keydate] = self.history_views[keydate]+1 DV, Scott Brodsky http://scottb.homepage.com icq:2202686, Yahoo:sbrodsky2000 Romans 14:11 ______________________________________________ FREE Personalized Email at Mail.com Sign up at http://www.mail.com/?sr=signup

Bug in DT_In.py, still using collector? Here's a patch
by Brad Clements 08 Aug '00

In Zope 2.2.0 If you have a bug in your DTML in a <dtml-in xx next> block, you don't see the bug. DT_In assumes that you just don't have more records to see. DT_In.py, around line 545 This code: elif next: try: # The following line is a sneaky way to test whether # there are more items, without actually # computing a length: sequence[end] pstart,pend,psize=opt(end+1-overlap,0, sz,orphan,sequence) kw['next-sequence']=1 kw['next-sequence-start-index']=pstart-1 kw['next-sequence-end-index']=pend-1 kw['next-sequence-size']=pend+1-pstart result=render(section,md) except: if self.elses: result=render(self.elses, md) else: result='' SHOULD BE: elif next: try: # The following line is a sneaky way to test whether # there are more items, without actually # computing a length: sequence[end] pstart,pend,psize=opt(end+1-overlap,0, sz,orphan,sequence) kw['next-sequence']=1 kw['next-sequence-start-index']=pstart-1 kw['next-sequence-end-index']=pend-1 kw['next-sequence-size']=pend+1-pstart except: if self.elses: result=render(self.elses, md) else: result='' else: result=render(section,md) Brad Clements, bkc(a)murkworks.com (315)268-1000 http://www.murkworks.com (315)268-9812 Fax netmeeting: ils://ils.murkworks.com AOL-IM: BKClements

RE: [Zope] Re:[Zope]Python Method question
by Chris McDonough 08 Aug '00

08 Aug '00

Ahhhh... I see. Thanks. Well, instead of calling execfile() (or exec()), make the PythonMethods for google and altavista, etc. part of your Product. Then replace the call to execfile with a call to the PythonMethod, eg. methods = [self.googlepythonmethod, self.altavistapythonmethod] for method in methods: count = count + 1 # whatever security stuff you're talking about... method() Does this make sense? I *think* this will work. -----Original Message----- From: entropia [mailto:entropiamax@jazzfree.com] Sent: Tuesday, August 08, 2000 10:05 AM To: Chris McDonough Cc: zope(a)zope.org Subject: Re: [Zope] Re:[Zope]Python Method question I am a Zope Newbie. I dont understand ZOpe too much. I know python but I am not an expert. Well, I want to make a Zope Product. There is a python program Pagecast (pagecast.sourceforge.net, I am not the creator) that I want to transform in a Product. This program submit a list of URL to various search engines. For each search engine there is a file that is executable code. My desire is that this files can be modified by any manager, not only the system administrator. For security reason I think that this should be a Python Method. In the original code I have: for file in Servers: count = count + 1 # TODO insert security here execfile(file, globals(), locals()) where servers is a list Servers=["google.def","altavista.def",...] As I said, this .def files are executable code. My question is: How can I execute this file if this file is a PythonMethod? Is that posible?

Referring to objects with an integer as id?
by Peter Arvidsson 08 Aug '00

08 Aug '00

How do I refer to an object that has an integer as id? I have pdf-files stored in a folder called "pdf". Now I want to be able to check their filesize. I looked in the API and found that this is done with getSize(self). I have no problem to refer to objects that do not have an integer as id. For example for the pdf-file with id "temppdf" this works: <dtml-var "pdf.testpdf.getSize()"> I have tried a number of different syntaxes to be able to check the filesize of an objct with an integer as id but nothing has worked For the pdf-file with id "11111111" I have tried this: <dtml-var "pdf.11111111.getSize()"> (gives me syntax error) <dtml-var "pdf.[11111111].getSize()"> (gives me syntax error) <dtml-var "pdf.['11111111'].getSize()"> (gives me syntax error) <dtml-var "pdf._['11111111'].getSize()"> (says I am unauthorized but I am sure I am not because I could access the same object if I gave it a string as id instead of an integer. I am the owner of both the object and folder and I have all privilages. Superuser wasnt authorized either.) <dtml-var "pdf._[11111111].getSize()"> (also says I am unauthorized) I have also tried all those combinations with _len() but that doesnt work either... Could someone please tell me how I can get the filesize of my objects with integers as their id?

General Full Text Search Questions
by Rogerio Atem de Carvalho 08 Aug '00

08 Aug '00

Hi, I have some general Full text search questions, hope someone can help me: 1)How can I use ZCatalogue to do full text search on static html pages? In Zcatalogue examples I could find search for properties like Title, I would like to have the whole text content of a static html searched. 2)Providing that the previous question was answered, how can I do the same for HTML pages referenced by LocalFS? 3)Can I combine LocalFS and Yihaw??? How? 4)How can I use Zope to generate static html pages stored outside Zope? Any help will be very apreciated!

permissions and ODBC
by cuiod-tec Jens Gelhaar 08 Aug '00

08 Aug '00

I use zope 2.2.0 and ZODBC-3.1.0b2. I get a strange behavior with ODBC access and permissions. To keep it simple, I have an ODBC-Connection and a SQL-Method. When I execute the SQL-Method everything works fine. When I call the same method from within an DTML-document I get asked for a password and whatever I try (even the super user), nothing works. I configured proxies, no success. What is wrong, maybe zope version and the ZODBC version do not like each other? Anyone an idea? Jens
