Problem with ZCTextIndex
by Braun Brelin 09 May '03

09 May '03

Hello, I've created a ZCTextIndex Lexicon object called 'ZCTextLexicon' in the root of my plone portal. However, when I try to add a ZCTextIndex in my portal_catalog tool, I get the following error (shown at the end of this e-mail). Anyone seen this before? Thanks, Braun Brelin LookupError Sorry, a site error occurred.

Calling a sequence-item functions
by Wim Bekker 09 May '03

09 May '03

I would like to call a python function from a sequence item: <dtml-in "Catalog(page_type='issuedtml')" prefix="x"> 1: <dtml-var expr="x_item.title"> 2: <dtml-var expr="x_item.GetTitle()"> 3: <dtml-var expr="x_item.GetObjectTitle(x_item)"> in class TrackerSupport I have: def GetTitle(self) return self.title def GetObjectTitle(self,object) return object.title 1: gives the correct title 2: gives the title from the page where the dtml code is in. 3: gives the correct title. Why is GetTitle not working? Where can I find some info on this subject? Wim

Displaying propertyValues for sequence-items
by Wim Bekker 09 May '03

09 May '03

I would like to see the propertyValues for sequence-items but I cannot get any results. I've tried the following: <dtml-in "Catalog()" prefix="x"> 1: <dtml-var x_item.propertyValues> 2: <dtml-var expr= x_item.propertyValues> 3: <dtml-var expr=x_item.propertyValues> 4: <dtml-var "x_item.propertyValues"> 5: <dtml-var expr="x_item.propertyValues"> 6: <dtml-var x_item.propertyValues()> 7: <dtml-var expr= x_item.propertyValues()> 8: <dtml-var "x_item.propertyValues()"> 9: <dtml-var expr="x_item.propertyValues()"> </dtml-in> Results: 1: Error Value: x_item.propertyValues 2: IE cannot display the page (because of the space after the = ?) 3: displays > 4: displays > 5: displays > 6: Error Value: x_item.propertyValues() 7: displays [''] 8: displays [''] 9: displays [''] What am I doing wrong? What is the attribute expr? It is not documented in the DTML reference. Where can I find documenation about these kind of issues? Wim

Re: [Zope-dev] PROPOSAL: ZODB Relationships
by Lennart Regebro 09 May '03

Jean Jordaan wrote: > You could still delete the storage if you wanted to kill all stored > relations, couldn't you? Well, yes, which yet again makes me think this is not a good path forward. It feels to me that the relation either should be stored in the object, and indexed somewhere, or there should be one central secret invisible storage. The relationship between two objects should not be deletable from "outside" the object, that seems really weird. If the relationship really is stored outside the object, then the only way to delete that relationship should be through an API. (With reasonable exceptions, such as deleting the ZODB, and setting Application.__relations = None, or something like that).

getting the data from a large File object in a python script
by Oliver Bleutgen 09 May '03

09 May '03

Question see subject. The problem is that file.data is not a string if the file is large enough (it's a linked list), and fileobj.data.next is not callable through a python script, so my ideas have run out. I want to insert an uploaded csv file into a database and don't want to use an external method for that .... TIA, oliver

CookieCrumbler and restricted Access
by Andreas Pakulat 09 May '03

09 May '03

Hi, I now use CookieCrumbler to authenticate the users, but I still got a problem. But first let me explain the site structure a bit: <HOME> |- acl_users - with all site-related users |- CookieCrumbler's cookie_authentication |- News | |- index_html | |- Editinterface The Problem is within the News folder, the index_html is accessible for everybody, but contains a dtml-if so that a Link to EditInterface is only provided for Logged in users. This works fine, but if I click this Link I have to authenticate again, even if I'm already logged in?! I've only disabled Acuirement for the View-permission of this file and set it for the Manager and the Webeditor role. Or do I have to add another cookie_authenticate to each Subfolder?

There is no type "Document" --- I guess I'm broken. Any guesses on how to fix it? This is install on FreeBSd. Python 2.1 installed from ports with increase stack patch.

Accessing httplib from a Zope Python script
by Sean Winstead 08 May '03

08 May '03

Hi, I'm a Zope newbie who's more familiar with C# than Python. I've encountered an obstacle and am unable to find what's wrong with my approach. In order to solve the problem, I have searched this group's archive as well as other resources on the web. Some posts earlier this month were related to the problem but didn't address it exactly. I'm trying to implement support for PayPal Instant Payment Notification (IPN). IPN sends a POST to a URL on our Zope server. I decided to implement a Python script to handle the POST. The first task of the script is to send a POST back to PayPal in order to verify the transaction originated from PayPal. To do that, I learned that I could use the features in the httplib module. However, if I have a crappy test script like the following: import httplib result = httplib.HTTP("http://www.paypal.com/cgi-bin/webscr") return result Then I receive the following error when posting to the page: Error Type: Unauthorized Error Value: You are not allowed to access HTTP in this context In my search for help, I learned that Zope allows Script objects to access a subset of the Python modules, so I assumed that was the reason for the error. In my search for help, I happened upon some articles about using External methods to access modules. So I put the "result = httplib..." line into function verifyPayPal, module ipnSupport.py within the Zope\Extensions subfolder. I then added the extension to the same folder containing the Python script. The extension has ID ipnSupport, referening the specified script and function. When I run the following script... result = verifyPayPal return result The following error is returned: Error Type: NameError Error Value: global name 'verifyPayPal' is not defined The same error occurs if I call ipnSupport instead of verifyPayPal. If I try to import module ipnSupport then the following error is returned: Error Type: ImportError Error Value: import of "ipnSupport" is unauthorized So I guess my questions are: 1. Why can I not import httplib into a Zope Python script object? 2. Is an external method only callable from a DTML object? If it can be called from a script object, how do I do that? Thanks for any help or clues you can provide. -- Sean Winstead
