Converting from DTML to ZPT
by Andreas Pakulat 19 May '03

19 May '03

Hi, I've got a little question conecring the transition from DTML to Page templates: Is there a counterpart with ZPT for the standard_html_header+index_html+standard_html_footer functionality? I'd like to completely remove DTML from my site, but I don't want to copy/paste the content of the header into each index_html of each subdirectory. Andreas -- Your supervisor is thinking about you.

Change Password From Product
by Matt Ficken 19 May '03

19 May '03

Is there a way that my product can change the password of an account if I'm using the product's management forms with a Manager account? I've tried calling userFolderEditUser but that doesn't seem to work. It doesn't generate an error message, but it doesn't change the password. -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup

Implementing class factory via ZClass or External Method
by Sean Winstead 18 May '03

18 May '03

Hi, In our Zope installation, I have implemented support for PayPal IPN via a Python Script. Now I am trying to reorganize the code so that we can support multiple payment processors. I want to implement one PaymentHandler class per payment processor and have a factory class that provides an instance of PaymentHandler depending upon the parameters submitted with the payment processor's request to Zope. However, I am having trouble determining how to implement this in Zope. I'm not sure if I should use a Zope Product/ZClass or if I should implement this via an external method. Regarding the former, is it true that an "instance" variable always refers to a variable tied to the particular instance of that product within a Zope folder? Can an instance variable be specific to the request that is being processed? For example, can the code parse a "customer ID" variable out of the request sent to Zope and retain that customer ID only for the duration of the request? Regarding the external method approach, I reorganized our code into an external method that instantiates a factory class. The factory class then creates an instance of the class appropriate to the request being processed. The external method called by Zope and the factory class are contained in the same module. The processor-specific class is contained in a separate module that is imported by the external method module containing the factory class. When the factory attempts to instantiate the processor-specific class, the following error is returned: NameError. global name 'payPalIPNHandler' is not defined. I have verified that class payPalIPNHandler does exist and that the case-sensitivity of the letters in the name are correct. Any advice or shedding of light will be appreciated. --- Outgoing mail is certified Virus Free.

Multiple ZODB Databases Within Single Zope Instance
by Samir Mishra 18 May '03

18 May '03

Hello All, I'm still new to Zope, so please excuse any stupid questions. I would like to split out some of the data contained within my ZODB (Zope's 'data.fs') into separate instances of the same. I THINK this may be an option for my application, where I have diverse users and requirements. Most importantly, a number of groups of users will be working off-site with a local Zope setup. While off-site, they do not have access to the corporate network. I need to integrate their local/updated 'data.fs' into the main Zope instance when they log in to the corporate network without resorting to exporting objects from within each group's instance of Zope to a '.zexp' and then re-importing into the main instance. I hope the above makes sense. My questions - a) Is this a sound approach, or is there a better way to do this? b) Has anyone done this before? If so, I'll be grateful for any advice. c) I feel this approach will fail with ZEO, probably due to the inherent complexity of maintaining multiple datafiles. Any comments or suggestions? Thanks in advance. Regards, Samir.

Keep Alive Connection
by Matt Ficken 18 May '03

18 May '03

My product needs to send data to the client, and then later send the client more data, over the same connection. HTTP/1.1 created Keep-Alive connections for this reason. I tried setting the response header 'Connection' to 'Keep-Alive', but Zope closes the connection anyway. So, I made an infinite loop in the function that is called when the connection is first opened, which keeps the connection open. Within the loop, the sleep function is called to sleep for 1 second, otherwise Zope sucks up all my unused CPU cycles. But, after I get 2 or 3 of these loops going, the whole Zope server locks up. It won't accept any connections. Is there a different way I can keep connections alive without locking up Zope or using all the system's CPU cycles? -- __________________________________________________________ Sign-up for your own FREE Personalized E-mail at Mail.com http://www.mail.com/?sr=signup
