getUsers cf. get_valid_userids question
by Geoff Gardiner 15 Jun '00

15 Jun '00

I want to show all users who have certain roles / and or permissions (Zope 2.1.6). I can't see how to do this directly, because I can't see how to get hold of user objects, which I need to carry out has_permission, etc., methods. I can show the userids of all valid users: <dtml-in get_valid_userids> <dtml-let uid=sequence-item> <dtml-var uid><br> </dtml-let> </dtml-in> but I can't get all actual user objects because getUsers is a method valid only for an identified User folder, and doesn't have acquisition. Should I just go in and code a new get_valid_users in the style of get_valid_userids, or is there another way? Perhaps there would be a security implication (I can't think what) but that's not a major issue for me at the moment. Thank you, Geoff

private Z Classes

Hi all, I'm trying to create a product with a Z Class (call it Z_Super) that contains other (private) Z Classes (call them Z_Subs). Creating Z_Super is no problem, but creating Z_Sub in Z_Super gives me the following traceback: Traceback (innermost last): File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 214, in publish_module File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 179, in publish File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/Zope/__init__.py, line 202, in zpublisher_exception_hook (Object: RoleManager) File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/Publish.py, line 151, in publish File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/BaseRequest.py, line 430, in traverse File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/AccessControl/User.py, line 375, in validate (Object: RoleManager) File /ford/sdrcsvr/u/zope/Zope-2.1.6-src/lib/python/ZPublisher/HTTPResponse.py, line 511, in notFoundError NotFound: (see above) FYI I'm using Zope 2.1.6.

Re: [Zope] Virtual hosts: How to make proper intra-site URL's?

It is at http://www.zope.org/Members/4am/SiteAccess . I don't use it myself, but apparently many people on the list do. I don't know if it's already safe to use it with 2.2 beta, but for a production site you probably won't run this anyway Rik

No, as long as it doesn't grow too much Gadfly will probably be fine (it is an in memory db) Another possibility is to use TinyTable, a contributed product by Ty Sarna. It's at http://www.zope.org/Members/tsarna/TinyTable Still another possibility is to use the Catalog to catalog news items. The Catalog approach has the advantage that your news items will be monitored dynamically. The Catalog is built into Zope hth Rik

Simple tabular data. Do I need SQL?
by rob＠hooft.net 15 Jun '00

15 Jun '00

On my web site, I have made a "News" page. The "News" items themselves are listed as a "lines"-property named "Items" on the News folder: date1;text1 date2;text2 ... They are accessed in a dtml-method: ------------------------ <dtml-var standard_html_header> <h2><dtml-var title></h2> <DL> <dtml-in Items> <dtml-let lin="_.string.split(_['sequence-item'],';')" dat="lin[0]" txt="lin[1]"> <P> <DT><dtml-var dat></DT> <DD><dtml-var txt></DD> </P> </dtml-let> </dtml-in> </DL> <dtml-var standard_html_footer> ------------------------- Since this is a small listing, this is still manageable. But: I do find the ";"-delimited fields a bit hackish, so I'm looking for a better way to handle this kind of very simple tabular data. Do I really have to go all the way to a proper relational database and learn SQL? Or is there another way? If I do need to go with a real database, do I have to pay attention to the "Demo Only" warnings in GadFly? Lots of questions from a python-loving-zope-newbie.....

SQL snippet...

Here's a quickie. If you're using MySQL and return integers, you'll see L added to the end of your numbers (it's a Python thing!) Try this <dtml-var result fmt="%u"> et volia!, no L added to the end of your numbers... Ithangyu.

Hi Everybody... I'm trying with ZCatalog. I've installed it properly and after creating one ZCatalog object, when I'm trying to click on it, it is asking for user name and password even though I'm super user for the Zope. It is showing the problem as unauthorized. I didn't get the point what I did the wrong. Pls. point me in right direction. Thank you in advance, Regards, Chandra Sekhar

SuperCannotOwn
by Hellekin O. Wolf 15 Jun '00

15 Jun '00

... La suite... Hello people ! I just installed a fresh v2.2.0b1 and bumped into some annoying problem. As the security model seems to have been changed, the superuser cannot own anything. That means we now need to install a new user with management access to get started. The question is : How to setup an "admin account" that will have the right to add new stuff ? * BTW, when i read the tutorial, there is the following alert prepended in red letters, while the content keeps displaying normally -- it seems so. Thanks for your help ! hellekin

LoginManager HOWTO?
by Cesar A. K. Grossmann 15 Jun '00

15 Jun '00

Hi! I'm trying to produce a web site with user authentication, and was looking for something more customizable than the standard user authentication mechanism provided by Zope. My first step was look in the Zope page, making a search on the term 'authentication'. I found three products: UserDB, GenericUserFolder, and LoginManager. Reading the page at the UserDB I found the bellow: "Update (10/30/99): Zen has posted a product that has more functionality than UserDB, called GenericUserFolder. " Well, looks like the GenericUserFolder is more advanced. So I go to its page. In it there are another observation: "Deprecated This product is being deprecated in favor of the LoginManager. LoginManager is what I like to believe that GUF would have been if I didn't have to write it in a hurry." Well, the next step is going to the LoginManager and try to figure out how to install it and put it in my web site. I get the package (I'm using the Linux version of Zope, in a Conectiva Linux 4.2 - like Red Hat 6.x -, installed from the rpm packages found in the Zope site), and, after some troubles to make ZPatterns fully functional, I get it installed. So now? No HOWTO explaining how to put it to run. Well, go to the mailing list, and search old messages. No one helps me... I'm looking for a sequence of steps needed to configure and use the LoginManager. How to add users? How to add local roles? How to integrate it whith LDAP (not for now, but in the future)? How to use a RDBMS server, like PostgreSQL, to store the accounts (in case I cannot put LDAP up an running)? I'm not a Python programmer, and I have a limited knowledge of Zope and DTML, and my english is only better than your portuguese... TIA -- César A. K.
