[Zope-dev] Reference files in a product folder

[Chris McDonough]

You're going to have to acquire the image objects from within an
instance of the 'main' ZClass to get a working URL to
them.

So in a DTML document within an instance of zclass 'main' called
'maininstance':

<dtml-var "myimagename.absolute_url()">

will work.

You can;t just go grab these things' URLs right out of the Product by
traversing the Control_Panel.Products.ProductName.ZClassName.ImageName and
calling absolute_url on that.  The reason is that though images are
capable of being placed in a zclass, they are not really methods, and as
such, the returned absolute_url from this traversal is wrong (it omits an
intermediate 'propertysheets' path member).  You *can* use handwritten
HTML to go grab the image like:

<img
src="Control_Panel/Products/LotsOfImages/main/propertysheets/methods/myimagename">

But you can;'t programatically generate this string using absolute_url().

This *might* be considered a bug
if we were sure that we really, truly wanted to allow images to be methods
of zclasses.  But I think for now it's one of those grey areas.
