[Zope] Displaying the text content of a ZClass

[Alexandre Ratti]

Hello,


I eventually found a solution for the problem described below.

Summary: I have a ZClass that subclasses DTMLDocument. In the ZClass 
product folder, I have an index_html method that provides a default view 
for ZClass instances. I want this method to display both property values 
and the text content of the ZClass instance.

To display the text content, if I use <dtml-var raw>, the text is displayed 
in unrendered form. Text and HTML code are OK but nested DTML is not 
interpreted. To display the text content in rendered form, I need to use 
<dtml-var "_.render(this())">.

Example code for index_html:

<dtml-var standard_html_header>
  <H2 align="center"><dtml-var title_or_id></H2>

<P><EM><dtml-var myDateProperty></EM><BR>
<dtml-var myDescriptionProperty></P>

  <dtml-var "_.render(this())">
<dtml-var standard_html_footer>


If there is a better way please let me know.


Cheers.

Alexandre
