CakePhP association not displaying as expected - cakephp

Question

I am new to Cakephp and I am having trouble with the following association. What I am after is listing Parts in a table, along with their associated Source vendor. So in the View/index.ctp the table I am currently getting is
ID Source Part #
1 1 Part00001
but I would like the association to display
ID Source Part #
1 Vendor 1 Part00001
where the Source.name is from the mstr_sources db table, not the mstr_parts table.
Below are snippets from all the pertinent code
class MstrPart extends AppModel {
public $name = 'MstrPart';
public $belongsTo = 'MstrSource';
}
class MstrPartsController extends AppController {
public function index() {
$this->set('parts', $this->paginate());
}
}
// <!-- File: /app/View/Users/index.ctp -->
<?php foreach ($parts as $part): ?>
<tr>
<td><?php echo $part['MstrPart']['id']; ?></td>
<td><?php echo $part['MstrPart']['mstr_source_id']['name']; ?></td>
//Also tried the following, still fails
//<td><?php echo $part['MstrPart']['MstrSource']['name']; ?></td>
<td><?php echo $part['MstrPart']['name']; ?></td>
</tr>
// Output of the error message context.
$viewFile = 'C:\Dev\UniServerZ\www\campman\app\View\MstrParts\index.ctp'
$dataForView = array(
'parts' => array(
(int) 0 => array(
'MstrPart' => array(
[maximum depth reached]
),
'MstrSource' => array(
[maximum depth reached]
)
)
)
)
$parts = array(
(int) 0 => array(
'MstrPart' => array(
'id' => '1',
'mstr_source_id' => '1',
'created' => '2013-12-18 16:10:35',
'modified' => '2013-12-18 16:10:35',
'name' => 'Part00001',
'description' => 'Just some basic text, not the real thing.'
),

'modified' => '2013-12-19 12:23:22',

)
)
)

)

Is there something obvious that I am missing?

Answer 1

I think you would just need to change this line
<td><?php echo $part['MstrPart']['mstr_source_id']['name']; ?></td>
To this
<td><?php echo $part['MstrSource']['name']; ?></td>
EDIT: I'll explain a bit.
In cakephp, all joined models (either joined via the 'join' tag within the Model->find, a containable behavior, or via the default bindings established in the model file) are included in the results array via a key of their model name. *it's their model name, not the table name. See cakephp naming conventions for more.
Since you want the column from mstr_source and not mstr_part, you want to reference the data inside the MstrSource dictionary and not MstrPart
