Hi guys,
I already searched for this problem but didn’t find any similar issues, so hopefully someone can help me
For a yii2 project I need to use the nested sets extentsion from creocoder (github.com/creocoder/yii2-nested-sets). What I did was to follow his readme and installed the extension with composer. After that I created a database table for test purpose with the relevant fields.
When I call the following two lines of code:
$countries = new Menu(['name' => 'Countries']);
$countries->makeRoot();
I receive an error:
Line 22 is ‘class’ => NestedSetsBehavior::className(),
public function behaviors() {
return [
'tree' => [
'class' => NestedSetsBehavior::className(),
// 'treeAttribute' => 'tree',
// 'leftAttribute' => 'lft',
// 'rightAttribute' => 'rgt',
// 'depthAttribute' => 'depth',
],
];
}
My namespace in this model is: use creocoder\nestedsets\NestedSetsBehavior;
What could be the problem here?
