CoffeeScript and Fibers are optional.

You can use Model with plain old JavaScript and Callbacks.

Defining Model

class global.Post extends Model
  @collection 'posts'
  @embedded   'comments'

class global.Comment extends Model
  

CRUD

post = new Post
  text: 'Zerg on Tarsonis!'

post.comments.push new Comment
  text: "Can't believe it!"

post.save()
  

CRUD

Post.first(status: 'published')

Post.
  find(status: 'published').
  sort(createdAt: -1).
  limit(25).
  all()
  

CRUD with Scopes

class global.Post extends Model
  @latest: ->
    @find(status: 'published').
    @sort(createdAt: -1).
    @limit(25)

Post.latest().paginate(params).all()
  

CRUD

post = Post.first()

post.comments.push new Comment
  text: 'Sad news ...'

post.save()
  

CRUD with Modifiers

post = Post.first()
post.update $set:
  title: 'Striking news!'

Post.update {_id: postId}, $set:
  title: 'Striking news!'
  

CRUD

post.delete()

Post.delete status: 'draft'
  

Associations

class global.Post extends Model
  comments: ->
    Comment.find postId: @_id

class global.Comment extends Model
  post: ->
    Post.first _id: @postId
  

Associations CRUD

post = Post.create
  text: 'Zerg found on Tarsonis!'

post.comments().create
  text: "Can't believe it!"
  

Associations CRUD

post = Post.first()

post.comments().limit(25).all()
post.comments().count()
  

Callbacks

class global.Post extends Model
  @after 'delete', (callback) ->
    @comments().delete callback
  

Validations

class global.Post extends Model
  @validate (callback) ->
    unless @text
      @errors.add
        text: "can't be empty"
    callback()
  

Callbacks and Validations also works on Embedded Models

If You declare attribute with embedded keyword

Billy

itSync "should be fine with Mary", ->
  Patient.create
    name        : 'Billy'
    temperature : 36

  billy = Patient.first()
  billy.temperature.should be: 36
