Customizing Zope FTP server
by Thierry FLORAC 12 Jul '05

12 Jul '05

Hi, I'm currently working on a Zope site, providing FTP access to some of it's sub-folders. My questions are : - is it possible to customise Zope FTP server so that a specific banner and a specific message are displayed on login ? - is it possible to "redirect" a user to a specific folder after a successful connection ? Thanks for any help, Thierry

Yes, forgot that caveat. For large files, 'data' can return a "Pdata", a list of strings. For small files, it returns a string. Always doing 'str' is a good idea. --jcc -- "Building Websites with Plone" http://plonebook.packtpub.com/ Enfold Systems, LLC http://www.enfoldsystems.com

Python Scripts
by Dennis Allison 11 Jul '05

11 Jul '05

We have been seeing a number of instances where python scripts fail due to an apparent "syntax error" but the syntax is correct and simply storing the method restores it to functionality.

aggreagating and merging logs under Zope 2.7.X

Is there any way to configure multi-headed Zopes running on different machines but sharing the same ZEO to log to the same file (in time order would also be nice...)? -- Dennis Allison * Computer Systems Laboratory * Gates 227 * Stanford University * Stanford CA 94305 * (650) 723-9213 * (650) 723-0033 fax * allison(a)shasta.stanford.edu * allison(a)sumeru.stanford.edu

undo many things
by Rakotomandimby (R12y) Mihamina 11 Jul '05

11 Jul '05

Hi, If I want to undo a very early action, I have to also undo all the actions done after the one I want to undo. The problem is that the action to undo is 4 pages earlier, so that I want to one time check all the actions of the 4 last pages. How to manage it? Thank you :-) -- Miroir de logiciels libres http://www.etud-orleans.fr Développement de logiciels libres http://aspo.rktmb.org/activites/developpement Infogerance de serveur dédié http://aspo.rktmb.org/activites/infogerance (En louant les services de l'ASPO vous luttez contre la fracture numerique)

ldap authentication with apache or LDAPUserFolder?
by Tim Suter 11 Jul '05

11 Jul '05

As some of you know, I am working on an installation of Zope/Zwiki. What I have inherited is a 2.5.1 Zope/Zwiki on a Debian box. I am wanting to move the data from the 2.5.1 to a 2.8. But here's the situation. At the root of the 2.5.1 install there is an acl_users folder that appears to be the LDAPUserFolder authentication mechanism. However, upon looking at the apache config on my Debian box you see this: <VirtualHost X.X.org:80> <location /Zope> AuthName "Knowledge Access" AuthType Basic AuthLDAPURL ldap://X.X.org:389/o=X.org?uid?sub?(objectClass=person) require group cn=caitstaff,ou=Groups,o=X.org </location> DocumentRoot /var/www ServerName X.X.org RedirectMatch ^/$ /Zope/ RewriteEngine on RewriteCond %{HTTP:Authorization} ^(.*) RewriteRule ^/Zope/(.*) /usr/lib/cgi-bin/Zope/$1 [e=HTTP_CGI_AUTHORIZATION:%1,t=application/x-httpd-cgi,l] </VirtualHost> I am trying to figure out what is authenticating the user, LDAPUserFolder or the AuthLDAP in Apache? In the root folder of the 2.5.1 install, there is our knowledge folder, argyle, inventory, a public folder. Those are the custom folders we created. The Zope install folders are the control panel, temp_folder, Tutorial, test. There is an acl_users folder, but it is not the original and has the LDAPUserFolder configuration in it. After authentication, the user is directed to the index_html which is in the root folder. The links present on this page point to our available knowledge bases (the custom folders we created). As well, it has a manage Zope link. Only certain users can access this link. Anyone authenticated to the knowledge bases though, can add, edit or delete content. This is the preferred method of this application as we want all users here to be able to openly collaborate. I need to authenticate the same way on the new install as the old one. Here is the dilemma though. On the new install of 2.8, it rests on an RHEL4 server. On this apache, I have to use authZLDAP as there is a documented bug with RedHat for the AuthLDAP. There are years of data collected in this knowledge base that I don't want to lose. So I am being about as careful as I can be...maybe too careful. So, question wise...I am wondering what authentication to use. I know that LDAPUserFolder appears to be the way to go, but I don't know if that is what is actually happening. By the looks of the above apache configuration, could there be some sort of redirection happening? Tim

sending e-mail in external methods
by Susana Beatson 11 Jul '05

11 Jul '05

Hello everybody, I am a new zope user that has received an application to maintain and I'm learning about zope at the same time. One of the features of the app requires users to subscribe to receive a newsletter. A user is presented with a very simple form <form method="post" tal:attributes="action string:${here/absolute_url}/Register" metal:fill-slot="content"> Name: <input name="name" type="text" tal:attributes="value request/name|nothing"> <br /> <br /> Email address: <input name="email" type="text" tal:attributes="value request/email|nothing"> <br /> <br /> <input type="submit" name="add" value="Submit"> </form> The code for Register simply validates the input and calls a function defined in an external module to send an e-mail to the person sending the request, to verify ownership of the e-mail address. This code is something like: errors = [] name = form.get('name','').strip() email = form.get('email','').strip() if not context.validateForm(email, name): errors.append('- Problems occurred with input data') if errors: errors.insert(0,'The following problems require correcting:') return context.register_index(messages=errors) import md5 from Products.PythonScripts.standard import url_quote sendEmail(['%s <%s>' % (name,email)], None, 'Newsletter Registration Request', """ Thank you for requesting more information about our Newsletter. Blah, blah, blah. To complete your registration please click on the link below %s/register/Register2?email=%s&name=%s&hash=%s Once you have done so, you will receive an e-mail confirming your registration. If you have any problems please email %s """ % ( container.absolute_url(), url_quote(email), url_quote(name), md5.new('%s%s%sSomeHashHiddenPassword' % (url_quote(email),url_quote(name))).hexdigest(), container.email_from_address), '') return context.register_index(name=name, email=email, message="A confirmation email has been sent to the address you provided.") The problem I have is that the sendEmail() function always requires the user to be logged in as manager of the portal to work. Whenever I click on the "Submit" button, I am asked to log in and the code will only proceed after successful log in. The same happens with Register2 that also sends an e-mail to confirm successful registration. When the user receives the e-mail to confirm his data and clicks on the link, he gets added to the database successfully and he should be sent an e-mail. But again, that only happens if the user is logged in as manager. As I am new to zope I'm sure I'm missing on something important about external methods, can anyone help? Thanks in advance, Squig.

zodb/transaction questions
by Jürgen Herrmann 11 Jul '05

11 Jul '05

hi all! this is not my first posting regarding my "before_transaction_commit" stuff, to summarize my plans: make the transaction object call a method "_before_transaction_commit()" on each changed object before the commit process starts. in zodb 3.2 style transactions it seemed to be easy, changed objects were stored in a list attribute of the transaction, attribute name was 'objects'. now in zope 2.8 we have zodb 3.4 and everything is different, there are managers/synchs to be registered, short question: how do i get at the modified objects cleanly? hope someone is fit in zodb hacking here :) regards, juergen herrmann _______________________________________________________________________ >> XLhost.de - eXperts in Linux hosting << Juergen Herrmann Weiherweg 10, 93051 Regensburg, Germany Fon: +49 (0)700 XLHOSTDE [0700 95467833] Fax: +49 (0)721 151 463027 ICQ: 27139974 - IRC: #XLhost@quakenet WEB: http://www.XLhost.de

Zope Newbie
by Emmanuel V. Salvador 11 Jul '05

11 Jul '05

Greetings to zope. I have just installed zope that came with the mandriva2000le(mandrake 10.2) and tried the excercise in the ZopeBook. All has been well until the guestbook exercise wherein a particular python script was granted manager rights in the proxy tab. Upon trying out the page with the script as an anonymous user, I'm asked for a username and password. According to the book, this was not suppose to happen since I already gave the script manager rights. Please refer to the error below. Site Error An error was encountered while publishing this resource. Error Type: Unauthorized Error Value: You are not allowed to access 'manage_addDTMLDocument' in this context Troubleshooting Suggestions * The URL may be incorrect. * The parameters passed to this resource may be incorrect. * A resource that this resource relies on may be encountering an error.
