I know, I know... few people are willing to recompile just for this (let alone the ones that have used the .rpm way). But if I want to, I *suppose* it'll just take a lot of grepping right ? But then, as is usually the case with computers, there's lots of difference between supposing and implementing. Would it be otherwise, ISPs would be admin'd by CEOs :-))))) Dimitris __________________________________________________ Do You Yahoo!? Yahoo!

user self registration using acl_users.manage_users
by Chris Jenson 15 Sep '00

15 Sep '00

I am using the following code (adding to acl_users folder with the manage_users page) to do user self registration after some initial authentication using Zope authentication and a common login/passwd. It works fine if things are as they should be, but when things go south, password and confirm not equal, login already exists, etc., it isn't so great. Looks like everything is fine, but the user isn't actually added. How can I capture the possible errors and return to the user? Help would be much appreciated. I am new to Zope and still trying to get my head around it. ********************************************* DTML Document-vendorRegistration <dtml-var standard_html_header> <h2><dtml-var title></h2> <p>Register for Vendor Manual distribution</p> <form action="registerAction" method="post" enctype="multipart/form-data"> <table> <tr> <td> Login(e-mail address): </td> <td> <input type="text" name="login"> </td> </tr> ... capture other stuff, like password, confirm, etc. <dtml-in expr="vendorManuals.objectValues()"> <tr> <td> <dtml-var title_or_id> </td> <td> <input type="checkbox" name="<dtml-var title_or_id>" </td> </tr> </dtml-in> </table> <input type="submit" value=" Register " > </form> <dtml-var standard_html_footer> ************************************************************* DTML Method-registerAction <dtml-var standard_html_header> <h2><dtml-var title></h2> <dtml-call "REQUEST.set('name', login)"> <dtml-call "REQUEST.set('password', password)"> <dtml-call "REQUEST.set('confirm', confirm)"> <dtml-call "REQUEST.set('roles', ['cwcVendor'])"> <dtml-call "REQUEST.set('submit', 'Add')"> <dtml-call "acl_users.manage_users(submit='Add', REQUEST=REQUEST )"> *******************************************************

Newbie - Zope won't start
by John VanDyk 15 Sep '00

15 Sep '00

I downloaded and installed Zope for Linux as per the instructions at zope.org. When I try to start Zope with ./start & I get a report that it has started up on ports 8080, 8021, and 8099. Then I get this: Traceback (innermost last): File "/usr/zope/Zope-2.2.1-linux2-x86/z2.py", line 708, in ? pf = open(PID_FILE, 'w') IOError: [Errno 13] Permission denied: '/usr/zope/Zope-2.2.1-linux2-x86/var/Z2.p id' I installed it as root and am root when I issue the start command. This is a stock Red Hat 6.2 Intel box.

Re: [Zope] Pluggable brains
by Dieter Maurer 15 Sep '00

gotcha(a)swing.be writes: > Is there a place where pluggable brains mechanism is described ? I forgot where I saw a description. But it is incredibly simple: You can wrap an arbitrary class instance around your database rows. This transforms your rows into full featured objects with the columns (among others) as attributes and the methods defined by the class as potential behaviour. What elso do you need to know? Dieter

dear zopists, im a zope newbie and i have one of those little problems ppl like me can spend hours on ... i just built my first ZClass and now im trying to automatically assign a generated ID to an instance of this class in the -add method. i want to generate the id because there is no unique fieldvalue available and i dont want to have the users get stuck on this point. another problem i encountered is that when i try to add an instance in a folder i get an authentication box where no valid login is accepted i would really much apreciate if someone could help.

You must know Python. You write a Python class, say "myClass" with all the extra attributes you like and all methods you may want to use for your database rows. You put the class into a source file, say "myExtensionFile" (or import it there). You place the file inside the folder "Extensions" (or, to keep namespaces separate, into an "Extensions" subfolder of a product). Then in the "Advanced Tab" of Z SQL methods, you say: I want to use class "myClass" from source "myExtensionFile" as custom class. That's it. Now, the rows retrieved by your query are "myClass" instances and have all additional attributes and methods you defined. Dieter
