Alternative mechanisms which achieve the same object? Well that depends on your objective, and you haven't told us what you want to do from a functional point of view.

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. For more detailed information about the error, please refer to the error log. If the error persists please contact the site maintainer. Thank you for your patience. Can anybody please give suggestions on how to change access rights for the error value above? Many thanks in advance, Noel S.

getSecurityManager() vs. AUTHENTICATED_USER
by Peter Bengtsson 09 Jul '05

09 Jul '05

I've learnt that it's better to use getSecurityManager instead of REQUEST.AUTHENTICATED_USER because it's more secure. Other than that, what is the difference. I fear I've come a across a situation when getSecurityManager() returns nothing where AUTHENTICATED_USER did. I'm currently trying to reproduce the situation but it might involve odd URL usage and it's a bore to have to restart the browser every time. Just hoping someone could give me a quick answer because I don't understand much simply by reading the source. from AccessControl import getSecurityManager class MyProduct(...): def Who(self): #return self.REQUEST.AUTHENTICATED_USER.getUserName() return getSecurityManager().getUser().getUserName() -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
