get and save unstructured document

[Klaus]

Hi folks,

one reason for me to change to couchdb is to have documents where I
can add a field or change the name of a field without influencing
other documents on the same database.

I got a document with CouchRest::ExtendedDocument. The only fields
which where accessible as objects in Ruby where the fields which I
defined as property. As I don't know which fields are included in the
document I can't define them all as property.
Is there a way to get the structure of the document to use them all as
objects? I want to save them as easily as 'xxxxx.save'.

Thanks, Klaus (Germany)

PS: I am newbie with ruby on rails and couchdb! Coming from perl and
mysql.

Documents are extended from hashes. You can find all actual data names without the use of properties using the #keys method. So, doc.keys would return an array of keys for data elements. You can access the values for these keys in the normal hash way hash[key_name]. If you want to set new unstructured values on a document, you can add them in the normal hash way too.
