ember-cli-simple-auth-devise initializer for setting endpoint. Lets you run on Rails localhost without proxy.

simple-auth-config.js

// app/initializers/simple-auth-config.js
export default {
  name: 'simple-auth-config',
  before: 'simple-auth',
  initialize: function() {

    var tokenEndpoint = '/users/sign_in';
    MyAppnameENV['simple-auth'] = {
      authorizer: 'simple-auth-authorizer:devise',
      crossOriginWhitelist:[
        MyAppnameENV.SERVER_URL
      ]
    };

    MyAppnameENV['simple-auth-devise'] = {
      serverTokenEndpoint: MyAppnameENV.SERVER_URL + tokenEndpoint
    };

    window.ENV = MyAppnameENV;
  }
};

assuming you set MyAppnameENV.SERVER_URL in your config/envronment.js in the correct environment section, ie. development, prod, etc.

@Genkilabs Can you put the environment.js file as well. Its so confusing!!
At first place, there ain't any MyAppnameENV, there is only MyAppname.
