A connect module based on a fork of sequelize-restful that adds a one level of associative capability to a restful API. It also lets you define which model should be exposed through this restful API.
This project is not actively developed/maintained. As a result of that, you won't be able to create issues any longer. I will happily merge pull requests, though. Please consider using finale or epilogue.
var express   = require('express')
  , Sequelize = require('sequelize')
  , http      = require('http')
  , restful   = require('sequelize-restful')
  , sequelize = new Sequelize('database', 'username', 'password')
  , app       = express()
// define all your models before the configure block
app.configure(function() {
  app.use(restful(sequelize, { /* options */ }))
})
http.createServer(app).listen(app.get('port'), function(){
  console.log("Express server listening on port " + app.get('port'))
}){
  // Parameter:   endpoint
  // Description: Define the path to the restful API.
  // Default:     '/api'
  endpoint: '/restful',
  // Parameter:   allowed
  // Description: Define which models will be exposed through the restful API
  // Default:     'new Array()' if it is an Empty array, all the models will be exposed by default
  allowed: new Array('Model0', 'Model1', 'Model2')
