Sorting case-insensitivly
by Peter Bengtsson 15 Aug '01

15 Aug '01

In the ZMI all the objects are by default sorted alphabetically starting with Capital A and ending with small z. What if you don't want it to be case sensitive? It's prett darn ugly the way it is at the moment. I do something like this: <dtml-in GetLotsOfObjects sort=id> And it returns Peter Zope bengtsson rocky When I'd like it to be: bengtsson Peter rocky Zope Cheers, Peter

Although I guess it could be argued Yes, I see that - but I didn't think any of the existing cookie-based products even did that... I thought they just encoded a concatenation of username and password in base64 (which is trivially decodable) and stored that. Was I not looking hard enough? > > Of course, I'm assuming that CST includes checks to guard against > > cookie-hijacking. :-) > > Um... maybe. What kind of checks did you have in mind? ;-) :-) Hmmm, let's see... OK, I've never done this myself but I remember reading that it's a good idea to do this kind of thing to your cookie values to ensure they're not hijacked: 1. Start with the data you want to store 2. Append identifying information, eg the IPs of the client and server, and the current date/time. 3. Make a digest of this plus a secret string which only you know, and append that as a fingerprint. Then when you interpret the cookie, check that the fingerprint is as you'd expect (ie the cookie hasn't been interfered with by a man in the middle) and then check anything else you want to check (eg the IP/date). Once you're happy with the fingerprint, you check that the server IP is the IP of the host box, that the client IP is good too, and that the date/time aren't unreasonably out of date - the idea is to guard against re-use of old cookies or cookies from somewhere else. As I say, I've never done this but it sounds reasonable in principle.

The Profiler for measuring Zope calculation times
by Kamon Ayeva 15 Aug '01

15 Aug '01

Hello, I have been using the Profiler from the Control Panel to try to figure ut the bottleneck parts of our site, but I don't really get results I can exploit. It goes too deep in Python for what I need at the moment. What I would need is some indication of the time used to calculate and render specific objects from the ZODB tree. For example the index_html rendering the contents of a specifc folder, or the left_bar_html if there is one called by this index_html. Is there a tool for doing that ? Regards, Kamon eXperts-MD

Instance of ZClass
by Walter Hupfeld 15 Aug '01

15 Aug '01

I want to build an instance of ZClass like <dtml-call "REQUEST.set('id',REQUEST.form['id_neu'])"> <dtml-with "manage_addProduct['Tauschboerse']"> <dtml-call "SkizzeClass_add(_.None,_, NoRedir=1)"> </dtml-with> <dtml-call "REQUEST.set('meine_skizze',_[REQUEST.form['id_neu']])"> <dtml-call "_['meine_skizze'].propertysheets.Beschreibung.manage_changeProperties({ 'Name':REQUEST.form['Name'], 'Email':REQUEST.form['Email'], 'Sprache':REQUEST.form['Sprache'], ..... where 'Sprache' is the name of a CHECKBOX. It works fine, if all checkboxes are checked. But if not all checkboxes are checked, I will get an keyerror. What can I do? -- ----------- -------------------- Walter Hupfeld --------------------------------

Authorization Help
by Todd Loomis 15 Aug '01

15 Aug '01

Hi: I'm trying to build a file system with access control. So when a user logs in they only see the folders/files they have access to see. Does anybody have any suggestions as I've tried and can't seem to get the Authorization to work, everybody gets to see everything.

CoreSessionTracking-based LoginMethod for LoginManager
by Andy Gimblett 15 Aug '01

15 Aug '01

Hi there Zopers, I'm currently trying to develop a LoginMethod for LoginManager which uses CoreSessionTracking to store/access credentials, rather than Basic HTTP Authorization or Basic Cookie Authorization. Here's why: - Basic HTTP auth is unacceptable because we need form-based login. - I've looked at other user folders which support cookies, and at CookieCrumbler, and at the BasicCookieLogin class bundled with LoginManager, but they all share the problem (in my mind) that they store the username/password encoded in the cookie itself, which isn't very secure - and doesn't extend well into storing other information if I wanted to. - I'd much rather use a token-based scheme where all sensitive information is stored on the server, and the cookie is just a token which can be mapped to that data. This seems to me to be what CoreSessionTracking offers. - The CST documentation mainly talk about CST as a way of tracking anonymous sessions, but I see no reason why it couldn't be used in this way too...? If we assume that the above reasoning is sound and that this is A Good Thing To Do, then I have the following problems: - I haven't written a fully-fledged disk-based product yet. I've looked at the tutorials and howtos but they're pretty basic. Helpful, but basic. I've successfully created a stripped-down do-nothing copy of the BasicCookieLogin class, but it's adding the extra (CST-related) parts that I'm having difficulty with. - If I could do it with a ZClass I reckon I could make it work, but I can't see a way to create a ZClass which LoginManager can use as a LoginMethod. There are subclasses for UserSources, but not LoginMethods. - Ideally I want it to be self-contained, so the LoginMethod instance would contain a SessionIdManager and a SessionDataManager - but I don't know how to do this properly/ morally/legally, or if it's even possible. - Another approach would be to have the LoginMethod pick up a SessionDataManager outside of it, but I'm having problems with this too... I tried hard-coding an expected ID in the LoginMethod and created a SessionDataManager with that ID in the LoginManager, but the acquisition didn't work. Maybe I'm missing something simple? Basically I have too many gaps in my knowledge to pull this together properly on my own, so it's time to ask for help. I'll be happy to expand on any of the above if necessary... I've sure learnt a lot about LoginManager and CST over the last few days, but I don't quite the skills to suit action to intent... :-( I'm assuming that this would be useful to other people if I could get it to fly? If that's the case, I'd love to release it. Similarly, if anyone wants to see the source of what I've tried so far, let me know. Other than that, all input appreciated.
