我如何在Yii2中通过hasMany获取表格？

Question

Using Yii2. I have a tables:

User

(id)

and

UserContacts

(u_id1, u_id2).

In model action:

return $this->hasMany(User::className(), ['id' => 'u_id1', 'id' => 'u_id2'])
            ->viaTable('UserContacts', ['id' => 'u_id1', 'id' => 'u_id2']); 

Prompt how can I get a table with users through viaTable ()?

Answer 1

return $this->hasMany(User::className(), ['id' => 'u_id2'])
->viaTable(UserContact::tableName(), ['u_id1' => 'id']);
