Method
__construct
($id = false, $table = null, $ds = null)

$id | mixed | optional Set this ID for this model on startup, can also be an array of options, see above. | false |
$table | string | optional Name of database table to use. | null |
$ds | string | optional DataSource connection name. | null |
Return
Comment
Constructor. Binds the model's database table to the object.
If `$id` is an array it can be used to pass several options into the model.
- id - The id to start the model on.
- table - The table to use for this model.
- ds - The connection name this model is connected to.
- name - The name of the model eg. Post.
- alias - The alias of the model, this is used for registering the instance in the `ClassRegistry`.
eg. `ParentThread`
### Overriding Model's __construct method.
When overriding Model::__construct() be careful to include and pass in all 3 of the
arguments to `parent::__construct($id, $table, $ds);`
### Dynamically creating models
You can dynamically create model instances using the $id array syntax.
{{{
$Post = new Model(array('table' => 'posts', 'name' => 'Post', 'ds' => 'connection2'));
}}}
Would create a model attached to the posts table on connection2. Dynamic model creation is useful
when you want a model object that contains no associations or attached behaviors.
@param mixed $id Set this ID for this model on startup, can also be an array of options, see above.
@param string $table Name of database table to use.
@param string $ds DataSource connection name.
