ember.js - Ember Data relationships being overwritten -

i've run problem on 2 separate instances both same problem. first here models 1 instance of problem:

host:

minicron.host = ds.model.extend({   hostname: ds.attr('string'),   name: ds.attr('string'),   created_at: ds.attr('date'),    jobs: ds.hasmany('job') }); 

job:

minicron.job = ds.model.extend({   name: ds.attr('string'),   command: ds.attr('string'),   created_at: ds.attr('date'),    host: ds.belongsto('host') }); 

the json job model receives:

{   "jobs":[     {       "id":"94e81ce07cec25451ce711fce3d96bea",       "name":"uname -a",       "command":"uname -a",       "created_at":"2014-03-10t16:25:08z",       "host":{         "id":8,         "hostname":"lucid32",         "name":"lucid32",         "created_at":"2014-03-08t18:13:52z"       },       "executions":[         {           "id":406,           "job_id":"94e81ce07cec25451ce711fce3d96bea",           "host_id":8,           "created_at":"2014-03-09t18:15:28z",           "started_at":"2014-03-09t18:15:28z",           "finished_at":"2014-03-09t18:15:28z",           "exit_status":0         }       ]     }   ] } 

and json host model receives is:

{   "hosts":[     {       "id":8,       "hostname":"lucid32",       "name":"lucid32",       "created_at":"2014-03-08t18:13:52z",       "jobs":[         {           "id":"94e81ce07cec25451ce711fce3d96bea",           "name":"uname -a",           "command":"uname -a",           "host_id":8,           "created_at":"2014-03-10t16:25:08z"         }       ]     }   ] } 

the problem i'm having when host model loaded job model's host relationship seems overwritten. presume because in json each job host has has host_id param , ember replacing existing data knows host nothing. api sinatra app using activerecord , activemodel serialize models json don't have easy way remove host_id response.

it's worth noting i'm using custom serializer here http://mozmonkey.com/2013/12/loading-json-with-embedded-records-into-ember-data-1-0-0-beta/, couldn't ember recognise sideloaded data without it.

i've been trying figure out few days , i'm out of ideas :(

let me know if have questions , if helps full source app on github https://github.com/jamesrwhite/minicron/tree/master/lib/minicron/hub

thanks!

you add active model serializers gem sinatra app , remove host_id response:

class jobserializer < activemodel::serializer     attributes :created_at, :started_at, :finished_at, :exit_status  end
