Add named get/set methods to backbone models

Model.coffee

addConvenienceMethods = ->
  for prop, value of this.attributes
    ((prop) ->
      #Define a setter/getter function
      this[prop] = (newValue...) ->
        if newValue.length
          this.set prop, newValue[0]
          return this
        else
          return this.get prop
      #Use the newly-defined setter function to store the default value
      this[prop](value)
    ).call(this, prop)

########## Base Model Superclass ##########
class exports.Model extends Backbone.Model
  initialize: ->
    addConvenienceMethods.call this

  idAttribute: '_id' #This provides MongoDB compatibility

  #Change the backbone validate API, which I dislike
  validate: =>
    errorInfo = new api.ErrorInfo()
    foundErrors = false
    for prop, value of this.attributes
      if this[prop] and typeof(this[prop].validate) == 'function'
        message = this[prop].validate value
        if message
          foundErrors = true
          errorInfo.errors[prop] = message
    if foundErrors
      return errorInfo
    else
      return false

  _performValidation: =>
    #Disable validation during calls to 'set'
    return true
