Ember-data find record by id and also additional parameters?

Question

In the Ember docs I found that find() has support for finding by id:

this.store.find('post', 1); // => GET /posts/1

And also by passing arbitrary parameters:

this.store.find('post', { name: "Peter" }); // => GET to /posts?name='Peter'

But in my case I must find by id, and pass an additional parameter to request all fields to be included in the response (some are omitted by default), like so:

this.store.find('post', 1); // => GET /posts/1?include=all

I tried to do it this way:

this.get('store').find('post', params.post_id, { include : 'all' });

But my params were ignored.

This seems a fairly basic use case so I must be missing something...

How can I accomplish this?

Rodrigo Marroquim answer didn't work for me. So I've come to the following solution
Ember v2.6.0

import Ember from 'ember';
import applicationAdapter from './application';

export default applicationAdapter.extend({
  findRecord: function(store, type, id, snapshot) {
    if (Ember.get(snapshot.adapterOptions, 'include')) {
      let url = this.buildURL(type.modelName, id, snapshot, 'findRecord');
      let query = {
        include: Ember.get(snapshot.adapterOptions, 'include')
      };
      return this.ajax(url, 'GET', { data: query });
    } else {
      this._super(...arguments);
    }
  }
});

usage:

this.get('store').findRecord('modelName', id, {
          adapterOptions: { include: 'all' }
});

You may have found a workaround the problem by now, but the way to go is to use the adapterOptions on the options argument.

So, let's go:

1. Where you fetch the model (i.e. a route), setup the custom argument you want. In your case, the include. It goes like this:

   //file app/routes/post/edit.js
   
   import Ember from 'ember';
   
   export default Ember.Route.extend({
     model: function(params) {
       return this.store.findRecord('post', params.post_id, {
         adapterOptions: { include: 'all' }
       });
     }
   });
   

2. Read this value inside the model's adapter to customize the ajax request:

   //file app/adapters/post.js
   
   export default JSONAPIAdapter.extend({
     findRecord: function(store, type, id, snapshot) {
       if (Em.get(snapshot, 'include')) {
         let url = this.buildURL(type.modelName, id, snapshot, 'findRecord');
         let query = this.buildQuery(snapshot);
         return this.ajax(url, 'GET', { data: query });
       } else {
         this._super(...arguments);
       }
   });
   

UPDATE 1:

On the ember-data newer versions (>= 2.4.0) you can do it out of the box, by calling store.findRecord('post', {include: 'all'});
