BACKBONE.SLOUCH

Ship code faster by making it obvious when you probably made a mistake.

When you Instantiate a Slouch.Model, the initial attributes, whether they come from the defaults object or from the argued attributes object, serve as the specification for what the model's attributes should always look like.

Example Instantiations

class Actor extends Slouch.Model
  defaults:
    color: 'blue'
    name: 'tobias'
    age: 34
    coach: new Actor()
    birthday: moment(0)
  deserializers: [
    test: (value) ->
      if moment(value).isValid() and _.isString(value)
        moment
  ]

model1 = new Actor()

model2 = new Actor
  color: 'yellow'
  name: 'gob'
  age: 35
  tricks: 'illusions'

Slouch.Model knows what it should know and what it shouldn't know.

model1.get('name')) # is 'tobias'
model2.get('age')) # is 34

model1.set('hair', true) # throws Error
new Actor {occupation: true} # throws Error
model2.set {poof: 'magazine', self_esteem: -400} # throws Error

model1.get('hair') # throws Error
model2.get('teeth') # throws Error

Slouch.Model knows what the "types" of its attributes should be

model1.set('name', 5) # throws Error
model2.set('age', 'is just a number') # throws Error

Slouch.Model currently will serialize and de-serialize using its type knowledge

Aside: it might be good to extract this into a separate project.

model1.set('coach', {color: 'gold', name: 'Carl', age: 56}) # Everything's cool.
model1.get('coach').get('name') # is 'Carl'
model1.toJSON().coach.name # also 'Carl'

now = moment()
model1.set('birthday', now.format())
model1.get('birthday').format() # is now.format()
