Condition in read() function CakePHP

In CakePHP function edit I use read() function as:

$this->data = $this->Article->read(null, $id);

It brings all fields of $id. Now, what I am trying to tweak to give one more condition in read() to get articles only if user logged in is related to it.

eg:

 $this->Article->user_id = $user_id;
 $this->Article->id = $id;
 $this->Article->read();

And obviously it want work as read() brings data only w.r.t. $id (primary key).

My question:

1. Is there any way to tweak read function with condition more than $id ? Because it will just need to add a o开发者_JAVA技巧ne line in all my controllers if it works ?
2. Or I have to use long code of find() function to get is the only option ?

Any best solution will be appreciable.

If you really must do thise, you could use OOP techniques to override the way the core method works.

Just copy the Model::read() method to your AppModel class and make the changes necessary.

You have to use find() if you want to make the search conditionally. Another option is to read the data only if the conditions hold:

$this->Article->id = $id;
if( $this->Article->field( 'user_id' ) == $user_id ) {
    $this->Article->read();
}

(read() populates $this->data automatically.)
