Body
Your question boils down to "How can I retrieve the Manager with id=1 and find his Employees. In CakePHP you would issue the following find query to retrieve the desired manager entry: <pre><code>$manager = $this->Manager->findById(1); // or $manager = $this->Manager->find('first', array( 'conditions' => array( 'Manager.id' => 1 ) ); </code></pre> The above find calls fetch the manager with id=1 from the database and because you set up the relationship Manager hasMany Employee, the result will also contain all employees for the manager ordered by Employee.created DESC. The resultset would look something like this: <pre><code>Array ( [Manager] => Array ( [id] => 1 [field1] => value1 ) [Employee] => Array ( [0] => Array ( [id] => 2 [manager_id] => 1 [name] => Bar ) [1] => Array ( [id] => 1 [manager_id] => 1 [name] => Foo ) ) ) </code></pre> As you can see, CakePHP uses an array format for returned results and not an object as in Ruby on Rails. Therefore you have to access your related data within the resulting array. Another important difference between CakePHP and Ruby on Rails(RoR) is, that in CakePHP the queries to the db are executed the moment you call them, whereas in RoR they are lazily executed the moment you try to access the results. To complement your RoR example for accessing employees here is the CakePHP version: <pre><code>$employee_count = count($manager['Employee']); foreach ($manager['Employee'] as $e) { echo $e['name']; } </code></pre> I hope this clears up some confusion.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
