How to auto-substitute lft, rgd for a nestedSet table that has only id and parent_id?

Question

Yii

Good day!
There is a table with a thousand records, which has id , prent_id and level .
I connect behavior for Yii NestedSetBehavior .
It is very desirable not to hammer lft and rgd manually. Help advice!

Answer 1

Use the api methods of the behavior you specified.
Also, don't forget that the hierarchical
nestedSet model allows you to specify the order of the elements of the same parent. This is what the lft and rgd keys are for. If this is not important, maybe you should choose a different storage model for hierarchical data.
