That's probably going to be your best bet in the long run, cheers, Chris

Please help - Persistent dictionary keys
by John D. Heintz 21 Sep '00

21 Sep '00

Can someone please explain the best way for me to map from one instance to another? In the following code either: (1) I am using dictionaries wrong, or (2) I'm missing something with ExtensionClass in general. I have tried searching Zope and Python mailing lists and resources for an answer to this question but have become confused by different conflicting messages. On the one hand I have heard that dictionary keys are supposed to be immutable. On the other, I've heard that dictionaries are used to simulate (key is object, value is ignored) some aspects of sets. Which is correct? What I really want is to be able to map a Persistent object to a string with fast lookup. Thanks for any help. John Heintz import ZODB from Persistence import Persistent class Test1: pass class Test2(Persistent): pass dict = {} t1 = Test1() t2 = Test2() try: dict[t1] = 1 except: print "Using instance of Test1 as key failed!" try: dict[t2] = 2 except: print "Using instance of Test2(Persistent) as key failed!" -- John D.

Potentially silly question: Any reason why a 'user folder' object has to be named 'acl_users'. -- E PLURIBUS LINUX

Re: [Zope] Restricting URL access to objects that are not complete web pages

You only want to see standard_html_footer and so forth when REQUEST.steps[-1]!=fragment_id, so it would not be accessible directly by URL. Try something like this for standard_html_footer: <dtml-if "REQUEST.steps[-1]=='standard_html_footer'"> <dtml-raise type="NotFound"></dtml-raise></dtml-if> </BODY></HTML> I think using siteaccess for this is more elegant, though.

acl_users.manage_users() and RESPONSE.redirect()
by Chris Jenson 20 Sep '00

20 Sep '00

I am using the following (adding to acl_users folder with manage_users) to do user self registration after some initial authentication using Zope authentication and a common login/passwd. It works fine if things are as they should be, but when things go south, password and confirm not equal, login already exists, etc., it isn't so great. I would like to get ahold of the output of manage_users to display on a redirected RESPONSE back to the original vendorRegistration DTML Document. How can I do this? Also, is there a better way to check for a successful user add? Right now I am using, " <dtml-if expr="acl_users.getUser(login)"> ", and that works, but wondered if there was a better way. Help would be much appreciated. thanks, Chris ***** DTML Document - vendorRegistration ****** <dtml-var standard_html_header> <h2><dtml-var title></h2> <p>Register for Vendor Manual distribution</p> <form action="registerAction" method="post" enctype="multipart/form-data"> <table> <tr> <td> Login(e-mail address): </td> <td> <input type="text" name="login"> </td> </tr> <tr> <td> Password: </td> <td> <input type="text" name="password"> </td> </tr> <tr> <td> Confirm Password: </td> <td> <input type="text" name="confirm"> </td> </tr> </table> <input type="submit" value=" Register " > </form> <dtml-var standard_html_footer> ***** DTML Document - registerAction ****** <dtml-var standard_html_header> <h2><dtml-var title></h2> <dtml-call "REQUEST.set('name', login)"> <dtml-call "REQUEST.set('password', password)"> <dtml-call "REQUEST.set('confirm', confirm)"> <dtml-call "REQUEST.set('roles', ['cwcVendor'])"> <dtml-call "REQUEST.set('submit', 'Add')"> <dtml-var expr="acl_users.manage_users(submit='Add', REQUEST=REQUEST )"> <dtml-if expr="acl_users.getUser(login)"> <dtml-var expr="RESPONSE.redirect('Registered')"> <dtml-else> <dtml-var expr="RESPONSE.redirect('vendorRegistration')"> </dtml-if> <dtml-var standard_html_footer>

XML-RPC - UTF-8 vs. Latin-1 encoding
by Skip Montanaro 20 Sep '00

20 Sep '00

I just stubbed my virtual toe on a problem with XML-RPC that I thought I'd fixed about a year ago. It has to do with the use of UTF-8 as the default encoding for XML-RPC. I twiddled my Python search path a little yesterday and unwittingly began picking up the Zope 2.2.1 version of xmlrpclib.py instead of the version I got from Fredrik Lundh and modified locally. When non-7bit-ASCII characters started popping up in my XML-RPC responses I began to get errors because those characters weren't properly encoded as UTF-8. The fix I applied for my own code was to observe that everything I did used Latin-1 and so I simply forced a Latin-1 encoding in all my requests and responses with <?xml version='1.0' encoding='ISO-8859-1' ?> When I twiddled sys.path yesterday I began picking up the Zope version of xmlrpclib and began having this Latin-1 vs. UTF-8 problem again. I retwiddled the path to get my version of xmlrpclib.py and things are once again fine. I have a couple questions: How are encodings handled in Zope (at least vis a vis XML-RPC)? I presume that in a Python 1.5.2-based environment such as Zope currently lives in, this is a potential problem. If so, where is the Latin-1 to UTF-8 conversion happening in Zope? It doesn't appear in Zope's version of xmlrpclib.py, nor in lib/python/ZPublisher/xmlrpc.py. Thanks, -- Skip Montanaro (skip(a)mojam.com) http://www.mojam.com/ http://www.musi-cal.com/
