Re: [Zope] ZClass derrived from Image does not call "view" from within <dtml-var>

I'm a Zope beginner. I'm trying to create an ImageTemplate ZClass. This will work similar to an Image, but the user can insert it directly in DTML using <dtml-var MyImage> and it will get expanded into HTML (with formatting, <img> tag, caption, etc.)

FWIW the Image object does exactly that already.

2. The Publisher does not call the view method (index_html) of the object! Instead it calls str() which is __str__ in Image and that calls Image.tag(). I can't overload __str__ because Zope does not allow a method to start with _ underscore.

This is the way it works! For creating ZClasses that render on __str__ see http://www.zope.org/Members/lalo/Renderable-ZClass HTH Stefan
