Re: [Zope] LoginManager with SQL and Skinscript: adding properties to propertysheet propertysheet

You may have noticed my silence on property sheets... At first, I didn't expect to use them, because I expected only members to edit their "properties" and I'm certainly not going to expose the standard Zope management interface to them. After going through the latest PTK sources some more, it looks like I may try using them after all. In either case, the important things to remember are: - The actual property data isn't stored in the ZClass or its property sheets, and the Skinscript code makes the ZClass "property" attributes have values with or without property sheets, and - The ZClass instances are ephemeral -- nothing is expected to store them for any length of time (though they may be cached). I created LoginManager:LoginUser subclassed zclass def for a user with a propertysheet Basic. It had properties password and email. The LM methods I tested failed so I deleted the properties. Now I want to add them again. When I try I get: for password Invalid property id, password. It is in use. for email: Invalid property id, email. It is in use. I also deleted the entire propertysheet and tried to add the props but the same error occured. I can add new props but not ones that were deleted earlier. Is there a way around this problem? I think you'll have to delete the whole ZClass and start over :-(. This shouldn't be too much of a pain because you shouldn't have any instances to worry about. If you've written custom methods, you'll want to copy them someplace before deleting the class.

[Zope] LoginManager with SQL and Skinscript: adding properties topropertysheet propertysheet

[Zope] LoginManager - With SQL
Thanks for the tips everyone!
I keep going between UserDb and LoginManager to try to get this to work.
UserDb gives me weird errors, and isn't really current, so I'm focusing on
LM.
I feel like I'm getting closer to a solution, but I'm still having
difficuties...
I followed jPenny's how to regarding accessing SQL method variables from
within python, and wrapped the retrieveItem result in a User Class. It
seems like it is at least running my code now, but no authentication...
Am I close? Can Anyone working with LoginManager offer any insight into
this?
Thanks!
-e-
Here's the code I have in UserSources.py
class User(BasicUser):
""" A wrapper for the basic user class """
icon='misc_/UserDb/User_icon'
def __init__(self, name, password, roles, domains):
self.name =name
self.__ =password
self.roles =filter(None, map(strip, split(roles, ',')))
self.domains=filter(None, map(strip, split(domains, ',')))
def getUserName(self):
return self.name
def _getPassword(self):
return self.__
def getRoles(self):
return self.roles
def getDomains(self):
return self.domains
class PGCryptUserSource(BasicUserSource):
""" A sql based encrypted user source """
meta_type="PG Crypt User Source"
__plugin_kind__="User Source"
def retrieveItem(self, name):
try: res=self.getuserbyusername(username=name)
except: return None
fields2index={}
fieldnames=res._schema.items()
for i in range(len(fieldnames)):
fields2index[fieldnames[i][0]]=fieldnames[i][1]
username=res[0][fields2index['username']]
password=res[0][fields2index['password']]
roles=res[0][fields2index['roles']]
domains=res[0][fields2index['domains']]
return User(username, password, roles, domains)
def rolesForUser(self, user):
name = user.getUserName()
res = self.getuserbyusername(username=name)
fields2index={}
fieldnames=res._schema.items()
for i in range(len(fieldnames)):
fields2index[fieldnames[i][0]]=fieldnames[i][1]
roles=res[0][fields2index['roles']]
return roles
def domainsForUser(self, user):
name = user.getUserName()
res = self.getuserbyusername(username=name)
fields2index={}
fieldnames=res._schema.items()
for i in range(len(fieldnames)):
fields2index[fieldnames[i][0]]=fieldnames[i][1]
domains=res[0][fields2index['domains']]
return domains
def authenticateUser(self, user, password, request):
name = user.getUserName()
res = self.getuserbyusername(username=name)
fields2index={}
fieldnames=res._schema.items()
for i in range(len(fieldnames)):
fields2index[fieldnames[i][0]]=fieldnames[i][1]
passwd=res[0][fields2index['password']]
if crypt.crypt(password,'ab')==passwd:
return 1
else:
return 0

Re: [Zope] LoginManager - with SQL?
Has anyone been able to use LoginManager with a SQL db? with or without encryption? I'm still baffled by this how-to: http://www.zope.org/Members/jok/SQL_based_LoginManager In this example, there are dtml-methods that do the work of the UserSource, but there is no retrieveItem? I would really love to get this working instead of having to revert back to older depreciated products. Thanks for any help! -e- From: "Aleksander Salwa" [EMAIL PROTECTED] I remember I had some troubles trying to put methods rolesForUser, domainsForUser, authenticateUser in UserSource class. They can be moved to user class. I did so. But your case is harder then mine, cause you don't have objects representing users in ZODB. Maybe there are problems with retrieveItem method ? Maybe you should build wrapper class around your database data - something like "pluggable brains" ? I have no more ideas :( ___ Zope maillist - [EMAIL PROTECTED] http://lists.zope.org/mailman/listinfo/zope ** No cross posts or HTML encoding! ** (Related lists - http://lists.zope.org/mailman/listinfo/zope-announce http://lists.zope.org/mailman/listinfo/zope-dev )
