Save a dashed model

Ember Data
1

Hi,

I’m in trouble with my model,

answer-group.js

import DS from 'ember-data';

export default DS.Model.extend({
  candidacy:          DS.belongsTo('candidacy'),
  survey:             DS.belongsTo('survey'),
  candidacy_answers:  DS.hasMany('candidacy-answer')
});

When i save my object the request to my api is like this:

POST "https://blabla.bla/answerGroups"
Parameters: {"answerGroup"=>{"candidacy"=>nil, "survey"=>"1"}, "answer_group"=>{}}

I update my RESTadapter with:

  pathForType: function(type) {
    return Ember.String.pluralize(Ember.String.underscore(type));
  },

Now, my uri is formatted correctly:

POST "https://blabla.bla/answer_groups"
Parameters: {"answerGroup"=>{"candidacy"=>nil, "survey"=>"1"}, "answer_group"=>{}}

My query params still in camelcase, how can i keep the snake_case ?
