If you do not have a C compiler on this windows box, then it will not work. 2.0.0 is alpha software. I do not recommend running it unless you are prepared to go to some extra effort to bootstrap yourself into using it. We cannot help you install it because all of our resources are commited to fixing bugs in 2.0, not doing tech support on install issues. I'd recommend downloading 1.10.2, which comes with Windows binaries. -Michel > Sure I have no Name server running on my box. > (Seems it won't be easy to find one.)

zope on a nearly bare win98 box?
by zhaoway 27 May '99

27 May '99

Dear Zoper, I wanna learn zope by practising. I wanna test Chinese. I currently have no Linux box by hand. And Linux cannot support Chinese inputing very well. (If all goes well, I will make a probablly big site on the Zope on top of a local distribution of Linux system, Xteam Linux, if you wanna know :) I got python 1.5.2 installed on my Windoze. Zope 2.0.0a1 compiled from src with double clicking on wo_pcgi.py and got compiled well, I guess :) Then following the INSTALL.txt, I tried \path\python z2.py -d 127.0.0.1 Got bunch of err msg ended with "ImportError: No mudule named ExtensionClass" Sure I have no Name server running on my box. (Seems it won't be easy to find one.) I've Hosts file under /windows though. Please someone could help me out. If necessary, I could go downloading some bit.

Do you thing ZOPE is ready for big use cases ? Yep. We've easily stored on the order of a million objects and the DB didn't mind at all. I would be confident going two orders of magnitude over that (100 million). I am being conservative with that estimate, Jim may give good technical reasons why you could go even higher. > 2.) I need big databases to ! Remember, Zope has excellent relational database integration. Zope and SQL servers have a very powerful symbiotic relationship. If you have lots of tabular, relational data and you'd like to use that data from other tools too, using SQL as part of your backend can be a very good idea. -Michel > > thanks a lot > Steph > > _______________________________________________ > Zope maillist - Zope(a)zope.org > http://www.zope.org/mailman/listinfo/zope > > (For developer-specific issues, use the companion list, > zope-dev(a)zope.org - http://www.zope.org/mailman/listinfo/zope-dev ) >

You can use a ZSQL method to insert your applicant into a table, or you can use a ZClass and instanciate an 'applicant' object. You could also use an external method to write the information out to disk so you can use it in another system (however if that other system supported SQL it would be preferable to use SQL) or you can use ZTables, a commercial product from Digital Creations. Of these I would recommend ZTables first, and SQL second. I would not recommend instanciating a ZClass because they are not designed to hold vast quantities of relational like information, they are good at abstracting out new Zope objects. Writing to a filesystem is a pretty ugly hack. Assuming you want to go the cheaper way (unless you pay more for your SQL server than ZTables costs (BTW, when you buy ZTables you get the source code, it's just not open and you can't redistribute it in any way)) then you probably will install a SQL server, create a Database Connection to that server, and then write a ZSQL method an 'INSERT' SQL operation in it. Then you can just call the method at this point. Note that your method must be looking for the above variables (in it's Arguments field) and that the above arguments should be valid, otherwise it will fail with an exception, so you may want to sanity check all your variables in some  blocks.  <h1>You got a name, right?</h1>    > >  > Why are you calling this here? It looks like you just want it to show the user information in a table, when you showed the information above. Perhaps you should factor this out and make the display of all users or a range of users a different component, and keep your component that adds records a simple component that just adds records. Overburdening one system with two functions is a recipie for bad design. Also, I wouldn't call a method in this context index_html, index_html has the special feature of being the default method called of an object (like a folder) if you don't specify one. Unless you plan on making this method also the default method, *and* you want to call it here, then go for it, otherwise I'd call it something like showTabulatedUsers or such. -Michel > > -------------------------------------------------------------- > -------------- > --------- > index_html should build a table from a list pf recoreds (instances) > -------------------------------------------------------------- > -------------- > --------- > > >

In your example above you have the developer role and the supervisor role. You might then be able to assign the developer role to the supervisor role. Now, this IS NOT the way it works today. Would this approach meet your requirement? With this approach the notion of role becomes much more like a notion of groups. >  >  >  At first glance exposing this stuff at this level would be pretty difficult since different objects can have different permissions associated with them. --Rob

The problem with your solution is that it doesn't take into account aquired permissions. >for i in AUTHENTICATED_USER.getRoles(): > if i in SomeObject._View_Permission.getRoles(): > return 1 >return 0

I'm not sure what your proposing other than using having different roles for each restricted area. And that makes roles a restrictive device. I have several areas and several groups of users. My roles represent a type of user not a type of access to a particular area. A role may enable access to many areas. This is how it supposed to work with roles as I understand it. The problem I'm trying to addess, which for some reason I can't seem to get across to anyone, is as follows. If say I development area to only users with role developer this is fine. I can then in my main page add a link to this development area that is viewable to only developers like so  <LI> <A HREF="development_area/index_html">Development Area</A>  This is fine and what I currently do. My argument is that if later I want say users with supervisor role to access the development area then I have to change the permissions on the development are and find all the has_role conditions in my code and change them. This is not huge point I realize but it seems to me a logical function that I should be able to perform. Show something if the user has permission to see it. It also means I can conditionally include DTML only if that user has permission to view that DTML. ie    If this not something that others see as important or is too hard then fine. I spent a couple of hours on it and couldn't find a nice way of doing it. I thought someone else could do it easier. A function called oldvalidate() looked promising but the name didn't seem to indicate its validity and with no documentation I couldn't work out the arguments. All I want is the security validation mechanism exposed more so I can use in DTML. Can this be done?

Has anybody tried to compile Zope2 with CygWin? I got Python 1.5.2 to compile and install, but I'm getting some compilation/linking errors when compiling Zope2. I know this is a bit vague, but then I'm feeling rather vague this morning ;) TIA Phil phil(a)philh.org
