ember.js - Dynamic Properties on Model with EmberJS -

below basic ember model:

app.person = ds.model.extend({   firstname: ds.attr('string'),   birthday:  ds.attr('date'),   day1: ds.attr('string'),   day2: ds.attr('string'),   day3: ds.attr('string') }); 

for purpose of example, if had days go 50? rather going line line... day4, day5, day6... there way loop through dynamically? first instinct use mixin, , push these onto object, don't think work if had computed property:

isholiday: function(){     if(this.get('day1') == 'off'){         return true;     } }.property('day1'), 

given 'this' in there , have return, don't believe can 'push' onto model generate this:

app.person = ds.model.extend({     firstname: ds.attr('string'),     birthday:  ds.attr('date'),     day1: ds.attr('string'),     day2: ds.attr('string'),     day3: ds.attr('string'),     isholiday: function(){         if(this.get('day1') == 'off'){             return true;         }     }.property('day1') }); 

this strange approach still possible:

var defaults = {     firstname: ds.attr('string'),     birthday:  ds.attr('date'),     isholiday: function(){         if(this.get('day1') == 'off'){             return true;         }     }.property('day1') }  var dayprops = {}; var count = 20; while(count--){   dayprops['day' + (count + 1)] = ds.attr('string'); }  app.person = ds.model.extend(ember.merge(defaults, dayprops)); 

instead defining dynamic props, better define day model , have one-to-many relations person:

 app.person = ds.model.extend({   days: ds.hasmany('day')   });   app.day = ds.model.extend({   person: ds.belongsto('person')   });
