Cataloging PageTemplates
by Mark Gibson 12 Dec '03

12 Dec '03

What is the simplest way of cataloging rendered page templates in a ZCatalog? Would first need to render the page template then strip html tags ( stripogram? ). It would be nice if PageTemplate would reindex iteself when it's changed. And when adding a new PageTemplate, if it would index itself in the catalog. Mark

Newbie - parameterized query...
by fowlertrainer＠anonym.hu 12 Dec '03

12 Dec '03

Hello , My problem is that: I have ZPT pages, and scripts. I want to check some infos with SQL query. This an example: script: ------- ss=context.REQUEST.SESSION r=0 uusr=usr.lower() result=context.LoginScripts.dbcheckUsrPwd(uusr,pwd) if len(result)>0: r=1 ss['userid']=row[0] ss["username"]=usr ss["full username"]=row[1] return(r) zsql: ----- params: usr,pwd select * from inst_prguser where webusr=<dtml-sqlvar usr type="string"> and webpwd=<dtml-sqlvar pwd type="string"> The result is: "Missing input variable, usr". I think this is wrong in zsql - it have wait for dtml-var. But how to I do it in good way to the zsql get good parameters ? Thanx. -- Best regards, fowlertrainer mailto:fowlertrainer@anonym.hu

If it comes in REQUEST it's easy to get. It comes in REQUEST. There is no issue here, I just added this as information. The important point is that no password is required from the user. > >2) How do I invoke an external program from Zope?!? > > > > > Any filesystem-based code can do it, using the usual Python > calls. (This means External Methods and Products.) Great. I just wanted to confirm that. Unfortunately, I don't have easy access to the file system (although I'm not completely blocked) so I wanted to know if there was a way around this. In a sense, it is reassuring that there isn't. :-) > > 3) Are there any "out-of-the-box" user folders that can > > handle this? I couldn't find any.

It wants to be able to create new users and edit the roles and password of an existing user. I'm not in a position to provide any of this. > ExtensibleUserFolder exUserFolder says that the one method that is mandatory is "listOneUser" which has to return the username, password and a list of roles for the user. In our system, I already know the identity of the person. I don't need to authenticate them. > PluggableUserFolder This folder is quite generic. Based on my reading of the "INTERNALS.txt" file, I would need to provide my own identification method (which would fit pretty simply into this), the authentication would really do nothing and the authorization should be based on local user data (information about roles) that would be maintained over and above our intranet indentification/authentication system. So this one is a possibility but a possibility with a perhaps steep learning curve and lots of coding. > all provide some simplified API for arbitrary user sources, > authorization, and authentication. The closest thing I have found is "RemoteUser" which identifies a user based on the REMOTE_USER environment variable. This would work great if I had access to REMOTE_USER, but it isn't clear that I will. In any case, it seems to function the way I want (it doesn't care about passwords, it just grabs the user's identity and adds them to the user folder if they don't exist already). This is along the lines of what I want, but it is going to require me to hack it a little bit in order to support our specific system. I was hoping for something that I might be able to configure "through the web". I'll also look into how authentication is done with SSL since that is very similar to what we do. Thanks. > --jcc -- Mike

Does anyone know how to create a Zope Product? One example would be the Local File System Object that I am using. If you could point me to some resources that would be great. Thanks. - Asad

Changing the Appearance of the Contents of a Local File System Object
by Asad Habib 12 Dec '03

12 Dec '03

Hello. I have a folder that I have created at the root level and inside this folder I have placed one Local File System object. The Local File System object contains two File objects. When I view the Local File System object by clicking on the 'View' option provided by the management interface, I can see that it contains two File objects. What I would like to do is to change the way that these File objects are displayed. Specifically, I would like to show only certain attributes that these File objects have and hide others. Right now, the following attributes are shown: type, icon, size, and last modified time(mtime). I would like to hide the size and last modified time(mtime) attributes. I want these attributes to be set but I do not want their values to show. FYI, I am using the Local File System Product. Any help would be greatly appreciated. Thanks. - Asad
