/** |

|
|
|
* ActiveRecord is the base class for classes representing relational data in terms of objects. |
|
20
|
|
|
* |
|
21
|
|
|
* Active Record implements the [Active Record design pattern](https://en.wikipedia.org/wiki/Active_record_pattern). |
|
22
|
|
|
* The premise behind Active Record is that an individual [[ActiveRecord]] object is associated with a specific |
|
23
|
|
|
* row in a database table. The object's attributes are mapped to the columns of the corresponding table. |
|
24
|
|
|
* Referencing an Active Record attribute is equivalent to accessing the corresponding table column for that record. |
|
25
|
|
|
* |
|
26
|
|
|
* As an example, say that the `Customer` ActiveRecord class is associated with the `customer` table. |
|
27
|
|
|
* This would mean that the class's `name` attribute is automatically mapped to the `name` column in `customer` table. |
|
28
|
|
|
* Thanks to Active Record, assuming the variable `$customer` is an object of type `Customer`, to get the value of |
|
29
|
|
|
* the `name` column for the table row, you can use the expression `$customer->name`. |
|
30
|
|
|
* In this example, Active Record is providing an object-oriented interface for accessing data stored in the database. |
|
31
|
|
|
* But Active Record provides much more functionality than this. |
|
32
|
|
|
* |
|
33
|
|
|
* To declare an ActiveRecord class you need to extend [[\yii\db\ActiveRecord]] and |
|
34
|
|
|
* implement the `tableName` method: |
|
35
|
|
|
* |
|
36
|
|
|
* ```php |
|
37
|
|
|
* <?php |
|
38
|
|
|
* |
|
39
|
|
|
* class Customer extends \yii\db\ActiveRecord |
|
40
|
|
|
* { |
|
41
|
|
|
* public static function tableName() |
|
42
|
|
|
* { |
|
43
|
|
|
* return 'customer'; |
|
44
|
|
|
* } |
|
45
|
|
|
* } |
|
46
|
|
|
* ``` |
|
47
|
|
|
* |
|
48
|
|
|
* The `tableName` method only has to return the name of the database table associated with the class. |
|
49
|
|
|
* |
|
50
|
|
|
* > Tip: You may also use the [Gii code generator](guide:start-gii) to generate ActiveRecord classes from your |
|
51
|
|
|
* > database tables. |
|
52
|
|
|
* |
|
53
|
|
|
* Class instances are obtained in one of two ways: |
|
54
|
|
|
* |
|
55
|
|
|
* * Using the `new` operator to create a new, empty object |
|
56
|
|
|
* * Using a method to fetch an existing record (or records) from the database |
|
57
|
|
|
* |
|
58
|
|
|
* Below is an example showing some typical usage of ActiveRecord: |
|
59
|
|
|
* |
|
60
|
|
|
* ```php |
|
61
|
|
|
* $user = new User(); |
|
62
|
|
|
* $user->name = 'Qiang'; |
|
63
|
|
|
* $user->save(); // a new row is inserted into user table |
|
64
|
|
|
* |
|
65
|
|
|
* // the following will retrieve the user 'CeBe' from the database |
|
66
|
|
|
* $user = User::find()->where(['name' => 'CeBe'])->one(); |
|
67
|
|
|
* |
|
68
|
|
|
* // this will get related records from orders table when relation is defined |
|
69
|
|
|
* $orders = $user->orders; |
|
70
|
|
|
* ``` |
|
71
|
|
|
* |
|
72
|
|
|
* For more details and usage information on ActiveRecord, see the [guide article on ActiveRecord](guide:db-active-record). |

557

630
|

|
|

* |
|
643
|
|
|
* ```php |
|
644

|
|
|
* ``` |
|
649

|
|
* Note that it is possible the update does not affect any row in the table. |
|
651

* In this case, this method will return 0. For this reason, you should use the following |
|
652
|
|
|
* code to check if update() is successful or not: |
|
653
|
|
|
* |
|
654
|
|
|
* ```php |
|
655
|
|
|
* if ($customer->update() !== false) { |
|
656
|
|
|
* // update successful |
|
657

* // update failed |
|
659
|
|

* } |
|
660
|
|
|
* ``` |
|
661
|

|
* |
|
662
|
|
|
* @param bool $runValidation whether to perform validation (calling [[validate()]]) |
|
663
|
|
|
* before saving the record. Defaults to `true`. If the validation fails, the record |
|
664
|
|

* will not be saved to the database and this method will return `false`. |
|
665
|
|

This check looks for function or method calls that always return null and whose return value is assigned to a variable.
The method
getObject()can return nothing but null, so it makes no sense to assign that value to a variable.The reason is most likely that a function or method is imcomplete or has been reduced for debug purposes.
