Implementation for the BluePrintREST:

Model

Simplified:

db.define_table('cr_shelter',
                SQLField('modified_on','datetime',default=now),
                SQLField('uuid',length=64,default=uuid.uuid4()),
                SQLField('name'))
db.cr_shelter.represent=lambda table:shn_list_item(table,resource='shelter',action='display')

Controller

# RESTful controller function
# Anonymous users can Read
# Authentication required for Create/Update/Delete
