[Fwd: Re: [Zope] [Newbie] Making my own authentication form - HOW
by Antonio Beamud Montero 08 Mar '02

08 Mar '02

I will describe how I solved "making my own authentication form" :-) Well my product is based in folders, and I need when create a instance of my product automagically create a user folder, a cookie mecanism and the login forms, but I don't want to touch the cookie crumbler login forms... I will do that: from Products.CookieCrumbler.CookieCrumbler import CookieCrumbler, manage_addCC class MyProduct(Folder): ..... def create_user_logins(self): """ Create the user login forms, etc...""" # Create the built-in user folder self.manage_addUserFolder() # create the Cookie Crumbler product instance, by default it # doesn't create login forms manage_addCC(self,'Cookies') # Example. How to create a user from an external method self.acl_users.userFolderAddUser('exuser','exuser',['Manager'],'') # Create our login forms self.create_login_forms() def create_login_forms(): addDTML(self, 'login_form','Pantalla de acceso', 'dtml/login_form') addDTML(self, 'logged_in', 'Pantalla de inicio', 'dtml/logged_in') addDTML(self, 'logged_out', 'Pantalla de salida','dtml/logged_out') #Piece of code from Squishdot :-) file_path=Globals.package_home(globals()) def addDTML(obj, id, title, file): f = open(file_path + '/' + file + '.dtml') file = f.read() f.close() obj.manage_addDTMLMethod(id, title, file) return getattr(obj, id) Inside my dtml directory I have three methods: login_form, logged_in, logged_out, in this moment are the login forms that comes with Cookie Crumbler product, but you can put all that you want... I hope that this howto help you... -- Microsoft merges technologoies: Windows CE + Windows ME + Windows NT = Windows CEMENT ---- Antonio Beamud Montero Agora Systems S.A. http://www.agoratechnologies.com

Re: [Zope] zope as win32 service and stupid_log_file
by Echlin, Michael 08 Mar '02

I am not sure if this applies or not but here goes. On a WIN NT server I wanted to get zope running with another program on the same server that also required python. Problem is it needed a different version of python that had been hacked and wouldn't work with Zope. It also set up some environment variables that zope couldn't live with. So I installed zope as an app and used srvany (part of the windows NT resource kit) to serve cmd calling a cmd file that set the variables to values zope could live with and then called zopes start.bat It is installed as an app and runs as a service in it's own virtual machine.

Creating a environment variable does not help. I can understand that because this would result in a conflict when running two versions of zope on the same machine. So there would have to be a environment variable that is bound to a specific service. zope 2.4.3. python 2.1.

Hi , I have my zope site running on the net. I have small problem.When iam accessing the site from inside the proxy server,old pages or cached pages are coming. I want to set a header in such a way nothing is cached in my proxy server. I had entered the following line in standard_html_header,but still sometimes pages come from cache. <dtml-call "RESPONSE.setHeader('Cache-Control','private,proxy-revalidate,no-cache,no-store')"> Does any one has the solution?Your response is of very value to me and very much appreciated. Thank you for your valuable time, regards, Dhanunjaya

Re: [Zope] Zope user limit?
by mick polo 07 Mar '02

07 Mar '02

Umm How do I do that? do I just install MySql - run it and then pick from a drop down selection in Zope as a ZSQL connection? sorry to sound stupid. can you lead me through it? Hi Mick, You do not need mailing list assistance with that. MySQL installation for Zope is very well documented. Please read Zope Book, available from http://www.zope.org free of charge: download the HTML tar.gz file, unpack using WinZip, and read the chapter Relational Database Connectivity. -- Milos Prudek Hi.. OHHH sorry I didn't make myself clear - I am working on Win 98, there is only one docco on installing Mysql with Zope on Win98, on zope.org and that didn't work because the vital files from there are missing... I'm moving to re-write this thing in PHP-Mysql-Apache Pity - ZOPE rock(ed) - I'll come back in a year or two to see if the Gadfly has improved (become fully threaded) - Thanx -I learned a lot with Zope - BUT IT's NOT QUITE THERE YET!!

'System resources exceeded' error with ZODBCDA and Access
by Igor Leturia 07 Mar '02

07 Mar '02

Hi all! I have Zope 2.3.2 installed on a Windows 2000 Server. I have an Access databases and I make queries on it using ZODBCDA. It works fine, but after some time running it gives an error which in English would be (more or less) 'Microsoft ODBC Error. System resources exceeded'. The only way to get it running again is restarting Zope? The database is not very big (about 8000 records). Is it a problem of ZODBCDA, or is it Microsoft's Access ODBC driver's? Do I have to change some parameter (cache, etc.) in any of them? Any help would be appreciated. Thanks in advance, Igor Leturia

ZPT: how to access property sheet of custom ZClass
by David Hart 07 Mar '02

07 Mar '02

Hi! I'm implementing a simple db, using the same methods in the JobBoard example. I looked at Kube, but I'd like something a bit more generic. I'm trying to make add/edit forms and display pages as simple as possible. Rather than have custom versions of all of these, each with copies of the same property names, I'd like to pull the property/attribute names from the property sheet of the ZClass in the Product I added. Something like: <span tal:repeat="props python:root.Control_Panel.Products.CEdb.cedb_record.propertysheets.common.record_default_properties.attrs()"> <p tal:content="props"></p> </span> The above example is probably very wrong for many reasons-- it shows my lack of experience with TAL, python and Zope innards in general -- but I think it conveys what I'm trying to do. I'm not sure if I can use "python:object.attrs()", or even if the objects under Control Panel are accessible to ZPT as the above example produces a guarded_getattr error. Also, is there a more generic or elegant way to refer to the record_default_properties object? Any help would be much appreciated! Regards, Dave

iterate over ZSQL method and make hidden form values...?
by Erik Myllymaki 07 Mar '02

07 Mar '02

I have a form that collects about 15 values, and a ZSQL method that collects about 15 values on the same page. I want to amalgamate them together and push them through to the next page where I could then use them all easily in another ZSQL method by just passing REQUEST. (note, I am using ZODBCDA so zsql_result.dictionaires() is unavailable to me!). Something like this(but that actually works ;-)): <form> <dtml-in zsql_method> <dtml-in sequence-item> <input type="hidden" name="<dtml-var sequence-item-name>" value="<dtml-var sequence-item-value"> > </dtml-in> </dtml-in> <many other inputs here................> <input type="submit" name="submit" value="go"> </form> Thanks, -- -- Erik Myllymaki erik(a)pacific-shores.com

Creates classes available to container but NOT add products menu
by chrisf 07 Mar '02

07 Mar '02

RegisterClass is cool But what if you don't want to register your product. When you create a product and add a ZobjectManager derived Zclass, all subsequent subclasses appear in the subobject menu but not the Products menu. I have a heap of classes. I do not want every class in the add Products menu. I do want them to be available to the top level container class. How do I do this from within python product code. Chris
