Overview

merb_relaxdb is a merb plugin that provides integration with CouchDB via the RelaxDB gem. Version numbers indicate compatibility with Merb. Revision numbers are excluded e.g. merb_relaxdb 1.0 should be compatible with Merb 1.0.x

The current release includes integration with merb-auth, but this should not yet be considered stable. A sample integration file is included below.

merb_relaxdb expects your merb app to augment the standard layout as described in the following tree.
couchdb.yml is mandatory. Reference data, sample data and views are optional.
merb-gen model my_model will create a sample couchdb.yml.

To use merb_relaxdb, list dependency "merb_relaxdb", "1.0" in config/dependencies.rb and use_orm :relaxdb in config/init.rb

For more details on using RelaxDB, see the RelaxDB wiki

    You need to setup some kind of user class with merb-auth.  
    Merb::Authentication.user_class = User
    
    If you want to fully customize your authentication you should use merb-core directly.  
    
    See lib/authentication/setup.rb and strategies.rb to customize your setup
