How to access query parameters from route in Ember 1.7

Question

In 1.7 Ember should support Query Parameters. I have no problems using them in controller but I'd like to access them in Route, ideally in beforeModel hook but model hook would work as well.

The API docs mention a queryParam parameter for the beforeModel hook but if I try to use it, it is always undefined.

The Query Parameters guide seems to suggest that the query parameters should be accessible as a part of the first parameter to the model hook. But that is also undefined. See the code below for examples.

Is there a way to access the query parameters from Route?

Thank you for your help.

App.ApplicationRoute = Em.Route.extend({
   beforeModel: function(transition, queryParams){
       console.log(queryParams.test); //undefined at /?test=123
   },
   model: function(params){
       console.log(params.test); //undefined at /?test=123
   }
}); 

Answer 1

Pretty sure it's a bug, but you can access them in the meantime via the transition object:

App.ApplicationRoute = Em.Route.extend({
   beforeModel: function(transition){
       console.log(transition.queryParams.test);
   }
}

By specifying the query params in the controller, params will contain them automatically

ApplicationController = Ember.Controller.extend({
  queryParams: ['test'],
  test: null
});

Answer 3

In the latest version of ember (2.12 at the time of writing this answer), queryParams can be accessed in the model hook as follows:

import Ember from 'ember';

export default Ember.Route.extend({
    queryParams: {
        test: ''
    },
    model(params) {
        console.log(params.test);
    },
});

Observe that now both dynamic segment and queryParams are accessible via the params object. Since params is not available in the beforeModel hook, this solution works on when you have to access the queryParams in the model hook.
