CakePHP中model-> alias和model-> name之间的区别是什么？

Question

alias and name are both properties in cake models. They seem to be similar, but since both of them exist, there must be a difference. What is it?

Answer 1

I'm guessing, but an alias could be the assigned value when you have a relationship between a model and another and you give the associated model a name not equal to that of the class.

For example:

$hasMany = array('UserNew' => array('className' => 'User'));

In that case, you're using the model that's actually called User, but you're referencing it as 'UserNew'.

Answer 2

It's a collection of table aliases used when cake does a join. From cake/lib/model/model_php5.php :

/**
 * Alias table names for model, for use in SQL JOIN statements.
 *
 * @var array
 * @access public
 */
    var $alias = array();

Answer 3

If you want to temporarily change the table in a model, and you're overriding the CakePHP magic FROM , change $this->alias to what you want it called. $this->name seems to be used in the constructor and must build the alias somewhere in that process. Changing $this->name in a method you want to override, is not enough. You'll have to change $this->alias and perform the method setSource() as in below:

function my_override_method(){
  $this->setSource('new_db_table_name_here');
  $this->alias = "NewTable";
}

Answer 4

• name : The name of the model, for example Post .
• alias : The alias of the model, this is used for registering the instance in the ClassRegistry , for example ParentThread .

Model::__construct( )
