hi ,
I am very new to couchdb, in my design , i just keep parent id of
each documents.
such as if i would like to delete B, i know that to delete C(have B id) and
then I have find and
to delete E(have c id).... etc.
my question is ....
1. is this possible ????
2. how do i pass the document id (such as B) to view that i would like
to search and delete document under its?
3. dose couchdb support delete document in view or i have to query all
of them than use http api to delete ?
thanks for every ideas
A.

It is common to store the full path to each item, on the item, so you'd have

then you can view easily across the tree.
however, reparenting a node, (say, moving B to become a child of D) require
asynchronous processing or a bulk docs request and is not transactional.
