CakePHP 3 - populate select dropdown with data from custom table - cakephp-3.0

Question

So I started looking at CakePHP, and I'm just doing a few test cases to see if CakePHP will cater for all my needs.
I have a custom table (Table name: roles):
id role sub_site
1 Role 1 0
2 Role 2 0
3 Role 3 0
4 Role 4 0
5 Role 1 1
In my controller (User controler) I have the following code based on all the feedback here.
$this->loadModel("roles");
$rolesList = $this->roles->find('list', array(
'conditions' => array('sub_site' => '0'),
'fields' => array('id', 'role')
));
$this->set(compact('rolesList'));
I have the following in the view
$this->Form->input('role', array('label'=>false,
'div'=>false,
'type'=>'select',
'empty'=>'-- select one --',
'options'=>$rolesList));
Yet the output looks like this:
<select name="role" required="required" id="role">
<option value="">-- select one --</option>
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
</select>
All I want is the output as follows:
<select name="role" required="required" id="role">
<option value="">-- select one --</option>
<option value="1">Role 1</option>
<option value="2">Role 2</option>
<option value="3">Role 3</option>
<option value="4">Role 4</option>
</select>
Please indicate what is wrong here as this is suppose to be simple to just populate?

Answer 1

I am getting results using this method. In my controller:
$articles = TableRegistry::get('Transfers');
$make=$articles->find('list', ['keyField' => 'id','valueField' => 'make']);
$this->set('make',$make);
and then in view:
echo $this->Form->input('make',['type'=>'select','options'=>$make ,'empty'=>'-Select Make-','class'=>'form-control','templateVars'=>['class'=>'col-md-4']]);
Hope you will get results.
