you will need to actually get the object from the string id <dtml-with "_.getattr(this(), document_id)"> <dtml-var body> </dtml-with> Or simply <dtml-var "(_.getattr(this(), document_id)).body"> I've not tested this.

Oh, I also didn't add the following bit of info. If I hard code the display_body method to be:

<dtml-var standard_html_header>

<dtml-with REQUEST>

<dtml-with name="001"> # 001 is the id of the message

<dtml-var body> # body is a text property of the message

</dtml-with>

</dtml-with>

<dtml-var standard_html_footer>

Then it works fine.

Thanks,

I used a Z class to write a basic news pinup board for my site. Everything is working fine but I reached a point where I am trying to publish only the heading and a summary of the message while asking users to click on a link to view the body of the message

I have created a newster class which is my news server instance. The newster class contains the messages class which is the blueprint for each of the messages that I am going to add. Each message is an object in the newster directory.

The message objects each have a number of properties such as expired, title, id, summary and body.

I have two methods:

1. index_html that prints the title and summary of each message instance one after the other on a long page.

2. display_body that will print the body of the message in a new window.

The problem:

I pass the id of the message whose body must be displayed in a url like: display_body?document_id=<id>

Here is what I believe the basic code of the display_body method should be:

<dtml-var standard_html_header>

<dtml-with REQUEST>

<dtml-with expr="document_id">

<dtml-var body>

</dtml-with>

</dtml-with>

<dtml-var standard_html_footer>

I can print the document_id as a dtml-var but somehow I cannot get zope to understand it is the name of an object whose body property I want to display.

But, somehow, zope does not push the properties of the document_id (which it received through the web) on top of the namespace and therefore it believes that there is no such thing as a body property.

Any help will be greatly appreciated. This is driving me nuts.

Thanks,

Pieter
