ember.js - Extending an Ember model with a custom variable -

my ember app has section model. has 'name' field , i've extended 'summary_of_changes' field. when effort length of name field good. attempts length of 'summary_of_changes' field generating error (see below) , driving me crazy.

this works:

# coffeescript app.sectioneditcontroller = ember.objectcontroller. isreadytosave: (-> @get('model.name').length > 3 ).property('model.name'),

but (almost identical code) doesn't

app.sectioneditcontroller = ember.objectcontroller. editmode: true, isreadytosave: (-> @get('model.summary_of_changes').length > 3 ).property('model.summary_of_changes'),

..and produces next error.

‘uncaught typeerror: cannot read property 'length' of undefined’

by way of farther background, store rails api , have model 'section' of business plan.the model contains: name, details not 'summary_of_changes'.

when save changes want submit summary_of_changes string in controller save save_comment along other save_comments changes section.

in essence want add together summary_of_changes temporary field saves model cleared blank 1 time again 1 time model saved.

in ember added field model:

app.section = ds.model.extend name: ds.attr('string') details: ds.attr('string') sort_order: ds.attr('number') plan: ds.belongsto('plan') summary_of_changes: ds.attr('string')

i have modal code (see illustration jsbin http://jsbin.com/hekaga/1/edit?css,js,output) refers 'summary_of_changes' field , able bind field changes modal live alter same named field in main section template.

i don't understand why though can see summary_of_changes field on template drop related modal , have 2 bound can't inquire it's length able other field on model.

versions: i'm running latest ember-rails (0.15.0) includes ember 1.5.11 , ember-data 1.0.0.beta.5

ember.js ember-data ember-model ember-rails
