acl_users
by Manfred Milhofer 26 Nov '02

26 Nov '02

Hi I'm having problems creating a new user in Zope. I want to allow a user access to one folder only, so my thinking was; - create a new user in acl_users and grant 'manager' role - grant access on said folder to manager However, simply adding the new user changes the password for the admin user as well, so i have to resort to a backup to continue (with no new user!). I'm obviously being very dim - I've tried searching the list but can't find anything, any help gratefully received. Manfred --- Outgoing mail is certified Virus Free.

Looping and total- summary variable use.
by Nick 26 Nov '02

26 Nov '02

Here's a newbie question regarding the use of summary variables and looping in dtml. How do you implement it? If I want to use the total-myvariable summary how do I call it? If I call it within the body of the loop it does not do any totaling. Does anybody have a good example? Thanks.

Zope wont serve, diagnose & repair suggestions?
by AdvertisingDept 26 Nov '02

26 Nov '02

After restarting my OS, my Zope installation stopped working correctly. I had been functioning correctly for days. I do not believe I changed anything in zope, so I am without a clue as to what caused it. When I log in to xxx.xxx.xxx:8080/manage as an administrator I get the menu on the left, but the main window never comes up. When I attempt to surf to my site xxx.xxx.xxx:8080 the index_html page never loads. When I force the issue by going to xxx.xxx.xxx:8080/manage_main the main window comes up and shows my items, but if I try to access any of them I go into a timeout. They never come up. How do I diagnose and repair this condition? Much thanks in advance.

I have used exUserFolder for local cookie based auth, but now need to add group permissions. I am looking at NuxUserGroups, but that only works with Basic Auth. Is my best solution to use NuxUserGroups + Cookie Crumbler? Thanks, mark

Hi, Is there a way by which we can access folders(as a whole) residing outside zope as like accessing files using External file? Help me if you can give me some pointers on how to achieve this. Regards, Paul.

Password Overlap
by Dan Shafer 26 Nov '02

26 Nov '02

I have painted myself into a nifty corner. My client's site is protected at the root by an acl folder. Those who are not in the acl folder have view privileges only. This works fine. I just added a new feature to my client's site. He wants this capability available to anyone to whom he gives a specific password. I wrote a Python script that generates the password and a page for my client to auto-generate a new random password and to see what the current password is. This works fine as well. The problem is, since I'm not even asking people for a user name here, only a password, and since the site is protected from access via the acl folder, his clients can't get past the password screen because the acl logic presents a challenge for a user name and password which, of course, these folks don't have. It occurred to me at one point that I could define an acl user called, e.g., "client" and then perhaps revise the Python script so that instead of storing the newly generated password in a DTML document, it would update the password property for that user in the acl folder. But it wasn't very obvious to me how to do that. And while I don't *mind* having them have to type in a generic user name, it's more elegant if they don't have to do so. What's the easiest way to address this issue? I looked through a year's worth of email digests and I searched zope.org, but I couldn't find an answer. Thanks.

multiple optional args to zsql method?
by Skip Montanaro 26 Nov '02

26 Nov '02

I have this ZSQL method: <params> id zope_username </params> select * from worker <dtml-sqlgroup where> <dtml-sqltest name="id" op="eq" type="int" optional> <dtml-or> <dtml-sqltest name="zope_username" op="eq" type="string" optional> </dtml-sqlgroup> ; When I test it but give no parameters it executes this SQL: select * from worker where zope_username = '' ; Since neither id nor zope_username were given shouldn't it have executed select * from worker ; ? I also tried using <dtml-and> instead of <dtml-or>. Same-o, Same-o. In addition, if I call it as context.sql.get_worker(zope_username=user.getUserName()) from a Python script, it complains "Invalid integer value for id". I'm flummoxed. -- Skip Montanaro - skip(a)pobox.com http://www.mojam.com/ http://www.musi-cal.com/
