Cushion

A HashWithIndifferentAccess with a CouchDB persistence layer.

Using Cushion is as simple as this:

hash = Cushion.new('/db/document')
hash.load
hash[:foo] = 'bar'
hash.save

When the document's URI consists only of the database part (/db), the id will be a UUID, set by CouchDB on .save.

Cushion can also be inherited from, which will lead to the database name being taken from the inheriting classes name. Like this:

class MyCushion < Cushion; end
hash = MyCushion.new
hash.save

In this case a document URI doesn't have to be given explicitly (even though, it can be given). For the above example, the URI would be /my_cushions/<UUID set by CouchDB>.
