/** |
|
* ActiveRecord is the base class for classes representing relational data in terms of objects. |
|
* |
|
* Active Record implements the [Active Record design pattern](http://en.wikipedia.org/wiki/Active_record). |
|
* The premise behind Active Record is that an individual [[ActiveRecord]] object is associated with a specific |
|
* row in a database table. The object's attributes are mapped to the columns of the corresponding table. |
|
* Referencing an Active Record attribute is equivalent to accessing the corresponding table column for that record. |
|
* |
|
* As an example, say that the `Customer` ActiveRecord class is associated with the `customer` table. |
|
* This would mean that the class's `name` attribute is automatically mapped to the `name` column in `customer` table. |
|
* Thanks to Active Record, assuming the variable `$customer` is an object of type `Customer`, to get the value of |
|
* the `name` column for the table row, you can use the expression `$customer->name`. |
|
* In this example, Active Record is providing an object-oriented interface for accessing data stored in the database. |
|
* But Active Record provides much more functionality than this. |
|
* |
|
* To declare an ActiveRecord class you need to extend [[\yii\db\ActiveRecord]] and |
|
* implement the `tableName` method: |
|
* |
|
* ```php |
|
* <?php |
|
* |
|
* class Customer extends \yii\db\ActiveRecord |
|
* { |
|
* public static function tableName() |
|
* { |
|
* return 'customer'; |
|
* } |
|
* } |
|
* ``` |
|
* |
|
* The `tableName` method only has to return the name of the database table associated with the class. |
|
* |
|
* > Tip: You may also use the [Gii code generator](guide:start-gii) to generate ActiveRecord classes from your |
|
* > database tables. |
|
* |
|
* Class instances are obtained in one of two ways: |
|
* |
|
* * Using the `new` operator to create a new, empty object |
|
* * Using a method to fetch an existing record (or records) from the database |
|
* |
|
* Here is a short teaser how working with an ActiveRecord looks like: |
|
* |
|
* ```php |
|
* $user = new User(); |
|
* $user->name = 'Qiang'; |
|
* $user->save(); // a new row is inserted into user table |
|
* |
|
* // the following will retrieve the user 'CeBe' from the database |
|
* $user = User::find()->where(['name' => 'CeBe'])->one(); |
|
* |
|
* // this will get related records from orders table when relation is defined |
|
* $orders = $user->orders; |
|
* ``` |
|
* |
|
* For more details and usage information on ActiveRecord, see the [guide article on ActiveRecord](guide:db-active-record). |
|
* |
|
* @method ActiveQuery hasMany($class, array $link) see [[BaseActiveRecord::hasMany()]] for more info |
|
* @method ActiveQuery hasOne($class, array $link) see [[BaseActiveRecord::hasOne()]] for more info |
