Hello
In Yii2, the use of a model – extends yii\db\activRecord (table), a modeloSearsh (ActiveDataProvider) and view (GridView:: Widget), allows, in full view, filter by column.
I’d like to achieve the same using a query (yii\db\Query) rather than a table. The query will have the information from multiple tables but will have to be treated in query and not in table, and if I use the sqlDataProvider, column filters stop working no view (GridView:: Widget)
Can somebody help me?
I can’t apply
“Using SQL views for filtering, sorting and displaying data
There is also another approach that can be faster and more useful - SQL views. For example, if we need to show the gridview with users and their profiles, we can do so in this way:
CREATE OR REPLACE VIEW vw_user_info AS
SELECT user.*, user_profile.lastname, user_profile.firstname
FROM user, user_profile
WHERE user.id = user_profile.user_id

I saw the following explanation
“Using SQL views for filtering, sorting and displaying data

CREATE OR REPLACE VIEW vw_user_info AS
SELECT user.*, user_profile.lastname, user_profile.firstname
FROM user, user_profile
WHERE user.id = user_profile.user_id"
Then you need to create the ActiveRecord that will be representing this view:
//*
namespace app\models\views\grid;
use yii\db\ActiveRecord;
class UserView extends ActiveRecord
{
/**
* @inheritdoc
*/
public static function tableName()
{
return 'vw_user_info';
}
public static function primaryKey()
{
return ['id'];
}
/**
* @inheritdoc
*/
public function rules()
{
return [
// define here your rules
];
}
/**
* @inheritdoc
*/
public static function attributeLabels()
{
return [
// define here your attribute labels
];
}
}
