CakePHP将project_id显示为名称

Question

My DB structure is quite simple: Projects has many Keywords.

In my Keywords/index.ctp I have a <Table> which shows all keywords and displays their project_id . Instead of the ID I want to display the name of the projects .

Is there a simple code-line for it?

Example:

keyword name | project 
Foo           1
bar           1
ipsum         2

to

keyword name | project 
Foo           DaFoo
bar           DaFoo
ipsum         MoreFoo

Answer 1

如果您在关键字模型中定义了belongsTo关系，那么您可以像这样访问Project数据：

$keyword['Project']['name'];

Answer 2

CakePHP Associations for more info please visit: http://book.cakephp.org/2.0/en/models/associations-linking-models-together.html

<?php 
class Keyword extends AppModel {

    var $name = 'Keyword';

    var $belongsTo = array(
        'Project' => array(
            'className' => 'Project',
            'dependent' => true
        )
    );
}

class Project extends AppModel {

    var $name = 'Project';

     var $hasMany = array(
        'Keyword' => array(
            'className' => 'Keyword',
            'dependent' => true
        )
    );

}

?>

and use in .ctp file as below

<?php 
$keywords['Project']['name'];
?>
