hello,

can anyone tell me where to find a dtml method or python script that checks whether a special document in a zope folder exists when called. dependend on this query i would like to carry out actions.

if "file exists" ....

else ....

thanks a lot,

Although Zope uses the term "folder" these objects are not very similar to a filesystem folder. In fact, _every_ zope object can (and would) have subobjects. Just to clarify this out. Zope is only a tree of objects, subobjects, subsubobjects and so on. (See your favourite python manual) In your case, if your namespace is mapped to _ you can use: if hasattr(_,'yoursciptobject'): ... or in DTML you would write <dtml-if yourscriptobject> ... </dtml-if> Please note: because of acquisition, subobjects with the same id are looked up on parent request containers.
