Yii2 hasMany relation additional condition
In Yii2, you can add additional conditions to a hasMany
relation by using the andWhere()
method. This allows you to filter the related records based on specific conditions.
Here's an example of how you can add additional conditions to a hasMany
relation in Yii2:
class Post extends \yii\db\ActiveRecord
{
public function getComments()
{
return $this->hasMany(Comment::class, ['post_id' => 'id'])
->andWhere(['status' => Comment::STATUS_APPROVED]);
}
}
In this example, the Post
model has a hasMany
relation called comments
. The comments
relation is defined to retrieve all comments that belong to the post with a specific post_id
. Additionally, the andWhere()
method is used to add an additional condition to the relation, filtering only the comments that have a status of Comment::STATUS_APPROVED
.
By adding the andWhere()
method to the hasMany
relation, you can further refine the related records that are returned when accessing the comments
relation on a Post
model instance.
Please note that the example provided assumes you have already defined the Comment
model and have a status
attribute in the Comment
model that represents the comment's status. You will need to adjust the example according to your specific model and attribute names.
I hope this helps! Let me know if you have any further questions.
