ZPatterns: Remapping object from on to another specialist
by jimbo 14 Nov '00

14 Nov '00

Now that the subject is on object remapping with Zpatterns. I'm not getting anywhere mapping between objects. I have a product folder EmployZ-Folder EmployZManager-Specialist WhoZ-Specialist Data Plug-ins myssMethod EmployZ-Zclass The EmployZManager just keeps a database of employee name, ID and salary. The WhoZ specialist keeps track of employee status like an in/out board. The Zclass for it is in another product. I'm trying to get the employee name from EmployZManagerto display in my WhoZ specialist. So I placed this skinscript in my WhoZ specialist data plugin tab. btw description and name is a WhoZ dataskin property myssMethod INITIALIZE OBJECT WITH original_object=EmployZManager.newItem(self.id) WITH EmployZManager.getItem(self.id) COMPUTE original_object=RESULT WITH self.original_object COMPUTE name=emp_id, description=first WHEN OBJECT ADDED,CHANGED STORE name, first USING self.original_object.manage_changeProperties( emp_id=self.name, first=self.description) WHEN OBJECT DELETED CALL self.original_object.manage_delete() Thanks -Jimbo

unbuffered html from external method
by Andy McKay 13 Nov '00

Is it possible to print unbuffered html output to the user from an external method. It looks to me like I can't, output occurs upon the return and I cant see a way of getting around that. (I have a very long running and expensive external method, I'd like to print out status to the user) TIA. -- Andy McKay, Developer. ActiveState.

Thanks. PortalMember is a ZClass in the PortalMembership product with bases: ZObject, _ZClass_for_DataSkin, _ZClass_for_LoginUser It has what appears to be a standard ZClass property sheet SystemProperties with a string property "password" (it also has other ZClass property sheets CommonProperties, RestrictedProperties, and UserProfile). PortalMembership is a .zexp file created by installing the Membership product.

Assume the following: ----------------------------------------- Folder1 index_html doc_include_html Folder2 img1 doc_include_html ----------------------------------------- 'doc_include_html' in 'Folder1' has the following code ----------------------------------------- <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>doc include Folder 1</p> <dtml-var standard_html_footer> ----------------------------------------- 'doc_include_html' in 'Folder2' has the following code ----------------------------------------- <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p>doc include Folder 2</p> <dtml-var standard_html_footer> ----------------------------------------- index_html has the following code: ----------------------------------------- <dtml-var standard_html_header> <h2><dtml-var title_or_id></h2> <p> This is the <dtml-var id> Document. Image: <img src=img1> size: <dtml-var "img1.getSize()"><br> Text: <dtml-var doc_include_html> </p> <dtml-var standard_html_footer> ----------------------------------------- when you call the URL http://localhost:8080/Folder1/Folder2 you see: This is the index_html Document. Image: ..... img2.... size: 11111 Text: doc include Folder 1 Why the acquisition get (correctly) Folder1/Folder2/img2 and the get (???) Folder1/doc_include_html instead of Folder1/Folder2/doc_include_html ? If you remove doc_include_html from Folder1 so that may assume: ----------------------------------------- Folder1 index_html Folder2 img1 doc_include_html ----------------------------------------- you see: This is the index_html Document. Image: ..... img2.... size: 11111 Text: doc include Folder 2 Thanks in advance, G.C. _________________________________________________________ Prometeo srl - The Software Experience Coi Giovanni Voice : +39 (041)5701366 Via Giudecca 15 Fax : +39 (041)5701005 30035 MIRANO (VE) - ITALY e-mail: coi(a)prometeo.it http://www.prometeo.it

Membership and latest LoginManager
by dan＠sol.control.com 13 Nov '00

I've been trying to get Membership 0.7.6 working with LoginManager-0-8-8b1 (and it's associated ZPatterns) under Zope 2.2.2 on RedHat 6.2. After probing around it seems that there is a problem storing member passwords. The following trace from print statements inserted in PersistentUserSource illustrates the problem: ================================================================== using crypt encodePassword( testing , scheme=' CRYPT ', salt= U3 ) ==> {CRYPT}U35nKDwqMBaD2addUser setting password for aral to "{CRYPT}U35nKDwqMBaD2" password = "{CRYPT}R0nzSkU8huehY" setting again with direct assignment password = "{CRYPT}U35nKDwqMBaD2" authenticateUser(self, aral , testing ) comparePassword( testing , {CRYPT}U35nKDwqMBaD2 ) using crypt encodePassword( testing , scheme=' CRYPT ', salt= U3 ) ==> {CRYPT}U35nKDwqMBaD2 comparePassword ==> {CRYPT}U35nKDwqMBaD2 == {CRYPT}U35nKDwqMBaD2 passwords matched ================================================================== Source bits with print statements follows at the end of this article. The problem seems to be that: ...manage_changeProperties(password = new_value) doesn't change the password correctly, but ...password = new_value works. Does anyone know what's really going on here? Modified from PersistentUserSource.py:PersistentUserSource: def authenticateUser(self,user,password,request): name = user.getUserName() ok=0 print 'authenticateUser(self,',name,',',password,')' if self.cacheGetAuth(name, password): return 1 if hasattr(self, 'userAuthenticate'): old_au = setuid(self.REQUEST, _LoggingInUser) try: ok = self.userAuthenticate( self, request, user=user, password=password) if ok: print 'self authenticated' finally: setuid(self.REQUEST, old_au) else: # Why does the following always return '{CRYPT}R0nzSkU8huehY' ??? encpw = user.propertysheets.SystemProperties.password print 'comparePassword(',password,',',encpw,')' ok = self.comparePassword(password, encpw) if ok: print 'passwords matched' if ok: self.cacheSetAuth(name, password) return ok def addUser(self, userid, password, roles, domains): user = self.newItem(userid) user.propertysheets.RestrictedProperties.manage_changeProperties(roles = roles) user.propertysheets.SystemProperties.manage_changeProperties(domains = domains) epass=self.encodePassword(password) # This always sets the password to '{CRYPT}R0nzSkU8huehY' !!! print 'addUser setting password for %s to "%s"' % (userid, epass) user.propertysheets.SystemProperties.manage_changeProperties(password = epass) print ' password = "%s"' % user.propertysheets.SystemProperties.password # This works - what is broken with the manage_changeProperties call? print 'setting again with direct assignment' user.propertysheets.SystemProperties.password = epass print ' password = "%s"' % user.propertysheets.SystemProperties.password return user Modified from LoginManager/UserSources.py:BasicUserSource def encodePassword(self, text, scheme='CRYPT', salt=None): """Encode a password""" if scheme == 'CRYPT' and crypt is not None: print ' using crypt' if salt is None: salt = whrandom.randint(0, 2**12-1) salt = saltdict[salt >> 6] + saltdict[salt & 0x3f] pw = '{CRYPT}' + crypt.crypt(text, salt) elif scheme == 'SHA': pw = '{SHA}' + binascii.b2a_base64(sha.sha(text).digest())[:-1] elif scheme == 'SSHA': if salt is None: # XXX random salt selection could be much better... salt = hex(whrandom.randint(0, sys.maxint-1))[2:] salt = sha.sha(salt).digest() ssha = sha.sha(text + salt).digest()+salt pw = '{SSHA}' + binascii.b2a_base64(ssha)[:-1] else: pw = text print "encodePassword(",text,", scheme='",scheme,"', salt=",salt,") ==> ",pw return pw def comparePassword(self, text, pw): """Check if password matches""" salt = self.extractSalt(pw) if pw[0] == '{': scheme = split(pw[1:], '}', 1)[0] else: scheme = '' text = self.encodePassword(text, scheme, salt) print 'comparePassword ==>',text,'==',pw return (text == pw)
