Dears, I have in a external method user = REQUEST.AUTHENTICATED_USER And so I can get user.getUserName(), user.getAllGroupNames() but I cannot find how to get user's full name and user's e-mail. Any idea? Many thanks in advance.

Z SQL Method properties
by David VanKirk 13 Feb '07

13 Feb '07

Does anyone know of a way that I can write a script to traverse through a folder of Z SQL Methods and find out the connection ID for each? Reason being, I have two connections objects for my ZSQL Methods to use. I'm trying to phase out the one and I'd like to write a script to tell me which ZSQL Methods need to have their connection IDs switch to the new connection object. I'd hate to have to go through each one by hand to find out. Thank you. -- David VanKirk

Re: [Zope] External Method importing modules

Well, I did it: from App.config import getConfiguration extPath = getConfiguration().instancehome+'/Extensions' if sys.path.count(extPath) == 0: sys.path.insert(0, extPath) And it worked for what I wanted.

Standard CookieAuthHelper and ZODBUserManager plugins are not enough for your use case? Seems that your problem (that you start like a Member but after clicking somewhere else you're unauthenticated) is because of code in extract credentials. What happens there? Credentials are extracted from request. So, if you have __ac_name and __ac_password in the request you're authentictated. When you're visiting another url, there is no __ac_name and __ac_password in request anymore, so you become unauthenticated. Right? So you have to store somewhere information about sucessful login. Solution might be the code I've sent you in previous mail. After authentication with __ac_name and __ac_password from the request it stores data in session. Then, on another pages session is checked for credentials and... you should be still authenticated. Another solution is to just use CookieAuthHelper which stores data in cookies. This is first part. You have credentials. Second thing is to compare them with users stored in ZODB (that what ZODBUserManager is doing...) -- Maciej Wisniowski

> In session object, but i don´t know how to do it. > Can you help me please???? Please stay on list. Something like: session = self.REQUEST.SESSION session.set('_key', credentials) to retrieve data: creds = session.get('_key', None) So after proper authentication you may store object with user name etc. in session and later just check if it is there. If so, then user is authenticated... In general this is how CAS4PAS plugin works. -- Maciej Wisniowski

Sorry about that, i will revert to the users list. The problem with the script is that it does not execute the os.system() commands at all, not that it generates the file at the wrong place or anything. Do you know why this happens and how i can remedy it? I seem to have found an old thread of someone facing the same problem but the suggestion solution is not appropriate for my case. I have even made sure that the CLASSPATHS have been set to the directory holding my .jar file http://mail.zope.org/pipermail/zope-dev/2003-June/019918.html Thanks again! wan Here is my code : def removeIllegalChars( tgtString ): import os import sys from yahoo.search.news import NewsSearch import re tgtString = re.sub('<([^!>]([^>]|\n)*)>', '', tgtString) tgtString = re.sub('<([^>]([^>]|\n)*)>', '', tgtString) tgtString = re.sub('\n', '', tgtString) tgtString = re.sub('\t', '', tgtString) tgtString = re.sub('\r', '', tgtString) tgtString = re.sub(' ', '', tgtString) if tgtString: try: tgtString = str(tgtString) except UnicodeEncodeError: tgtString = str(tgtString.encode('U8')) return tgtString def getYahooAPI(): import os import sys from yahoo.search.news import NewsSearch import re queryWord = "Singapore" print ("Fetching data from YahooAPI with query : " + queryWord ) srch = NewsSearch('YahooDemo',query = "Singapore asean cup", language = 'en', results = 50) info = srch.parse_results() info.total_results_available homedir = os.getcwd() tgtFile = homedir + "/Extensions/InputString.txt" writeFile = open(tgtFile, 'w') for result in info.results: writeFile.write("<Article>\n") writeFile.write("<Title>\n") writeFile.write(removeIllegalChars(result['Title'])+ "\n") writeFile.write("<URL>\n") writeFile.write(removeIllegalChars(result['ClickUrl']) + "\n") writeFile.write("<Summary>\n") writeFile.write(removeIllegalChars(result['Summary']) + "\n") writeFile.write("<Date>\n") writeFile.write(removeIllegalChars(result['PublishDate']) + "\n") writeFile.write("<Source>\n") writeFile.write(removeIllegalChars(result['NewsSource']) + "\n") writeFile.write("<Body>\n") writeFile.write(removeIllegalChars(result['Summary']) + "\n") writeFile.write("<EndOfFile>") writeFile.close def runYahooSearch2(self): import os import sys from yahoo.search.news import NewsSearch import re #----------------------------------------------------------------------------------------------------------- # still trying to figure out how to get the absolute path to this script # commands below work for windows... but not for linux.

Migrating the OpenFlow project from Zope 2.7.x to 2.9.x (and 2.10.x)
by Marco Bizzarri 12 Feb '07

12 Feb '07

Hi all. I'm in the business of migrating OpenFlow from Zope 2.7.x (where it lived peacefully) to Zope 2.9 and 2.10 (i.e. I'm in the process of 2.9, and then I will move to 2.10). As a first step, I've run the unit tests for the project, and just one is failing, the following one: <code> def afterSetUp(self): self.zope = self.app # create an openflow self.zope.manage_addProduct['OpenFlow'].manage_addOpenflow(id='OF') self.of = getattr(self.zope, 'OF') # Create a Process Definition with two activities (Begin, End)... self.of.addProcess(id='begin_end', BeginEnd=1) self.pd = getattr(self.of, 'begin_end') # ...and one transition linking them self.pd.addTransition(id='begin_end', From='Begin', To='End') loginUnrestricted() def testCopyOpenflow(self): cataloged_items = len(self.of.Catalog()) cb = self.zope.manage_copyObjects([self.of.id]) try: for i in [self.of, self.pd] + self.pd.objectValues(): assert hasattr(i.aq_base, 'getId'), "missing %s" % i.id assert i._getCopy(self.zope) is not None, "getcopy not in %s" % i.id except AssertionError: # this test is tough to make! how to do this? return self.zope.manage_pasteObjects(cb) new_of = getattr(self.zope, 'copy_of_'+self.of.id) self.assertEquals(len(new_of.Catalog()),cataloged_items) </code> Just for a little of further knowledge: OpenFlow creates a Catalog, which is used to access all the data of the Workflow (processes, instancess, workitems, etc.) The assertion failing is the last one, because I get a length of 0 as a result of the query of the catalog. Can someone point me to differences between 2.7 and 2.9 in the handling of the paste action? Regards Marco -- Marco Bizzarri http://iliveinpisa.blogspot.com/
