debug = require('debug')('carcass:model:lorem')

lib = require('../')
modella = require('modella')
validation = require('modella-validators')

module.exports = Lorem = modella('Lorem')

Lorem.use(validation)
Lorem.use(lib.plugins.modellaCouch)

 * The DB instance.
###
Lorem.db = ->
    config = lib.get('Lorem') ? {}
    dbName = config.dbName ? 'lorems'
    return lib.singletons.dbs[dbName] ? lib.singletons.couch.getDB(dbName)

 * Just an example.

###
Lorem.on('saving', (lorem, done) ->
    # Fix name.
    lorem.name(lorem.name().toLowerCase())
    done()
)

###*
 * Just an example.
 *
 * While loading.
###
Lorem.on('loading', (lorem, done) ->
    # Fix name.
    lorem.name(lorem.name().toLowerCase())
    done()
)

###*
 * Just an example.
 *
 * After load.
###
Lorem.on('load', (lorem) ->
    lorem.loadedFromDB = true
)

###*
 * Just an example.
 *
 * @param {Object} model the model that just failed to update (conflict with
