Usage

var caminte = require('caminte');
var Schema  = caminte.Schema;
var schema  = new Schema('redis', {port: 6379});

// define models
var Post = schema.define('Post', {
    title:     { type: schema.String,  limit: 255 },
    userId:    { type: schema.Number },
    content:   { type: schema.Text },
    created:   { type: schema.Date,    default: Date.now },
    updated:   { type: schema.Date },
    published: { type: schema.Boolean, default: false, index: true }
});

var User = schema.define('User', {
    name:       { type: schema.String,  limit: 255 },
    bio:        { type: schema.Text },
    email:      { type: schema.String,  limit: 155, unique: true },
    approved:   { type: schema.Boolean, default: false, index: true }
    joinedAt:   { type: schema.Date,    default: Date.now },
    age:        { type: schema.Number },
    gender:     { type: schema.String,  limit: 10 }
});

// setup hooks
Post.afterUpdate = function (next) {
    this.updated = new Date();
    this.save();
    next();
};

// define any custom method for instance
User.prototype.getNameAndAge = function () {
    return this.name + ', ' + this.age;
};

// define scope
Post.scope('active', { published : true });

// setup validations
User.validatesPresenceOf('name', 'email');
User.validatesUniquenessOf('email', {message: 'email is not unique'});
User.validatesInclusionOf('gender', {in: ['male', 'female']});
User.validatesNumericalityOf('age', {int: true});

// setup relationships
User.hasMany(Post,   {as: 'posts',  foreignKey: 'userId'});

// Common API methods

var user = new User({ 
    name:       'Alex',
    email:      'example@domain.aga',
    age:        40,
    gender:     'male'
});

user.isValid(function (valid) {
    if (!valid) {
        return console.log(user.errors);
    }
    user.save(function(err){
        if (!err) {
            return console.log(err);
        }
        console.log('User created');
    });
})

// just instantiate model
new Post
// save model (of course async)
Post.create(cb);
// all posts
Post.all(cb)
// all posts by user
Post.all({where: {userId: user.id}, order: 'id', limit: 10, skip: 20});
// the same as prev
user.posts(cb)
// get one latest post
Post.findOne({where: {published: true}, order: 'date DESC'}, cb);
// same as new Post({userId: user.id});
user.posts.build
// save as Post.create({userId: user.id}, cb);
user.posts.create(cb)
// find instance by id
User.findById(1, cb)
// count instances
User.count([conditions, ]cb)
// destroy instance
user.destroy(cb);
// destroy all instances
User.destroyAll(cb);

// models also accessible in schema:
schema.models.User;
schema.models.Post;

Package structure

Now all common logic described in ./lib/*.js, and database-specific stuff in ./lib/adapters/*.js. It's super-tiny, right?
