Nested Tree for Laravel
The nested set model is an advanced technique for maintaining hierachies among models using parent_id, nest_left, nest_right, and nest_depth columns. To use a nested set model, apply the ArtisanWebLab\NestedTree\Database\Traits\NestedTreeTrait trait.
Creating a root node
By default, all nodes are created as roots:
Alternatively, you may find yourself in the need of converting an existing node into a root node:
You may also nullify it's parent_id column which works the same as `makeRoot'.
Inserting nodes
You can insert new nodes directly by the relation:
Or use the makeChildOf method for existing nodes:
Deleting nodes
When a node is deleted with the delete method, all descendants of the node will also be deleted. Note that the delete model events will not be fired for the child models.
Getting the nesting level of a node
The getLevel method will return current nesting level, or depth, of a node.
Moving nodes around
There are several methods for moving nodes around:
moveLeft(): Find the left sibling and move to the left of it.moveRight(): Find the right sibling and move to the right of it.moveBefore($otherNode): Move to the node to the left of ...moveAfter($otherNode): Move to the node to the right of ...makeChildOf($otherNode): Make the node a child of ...makeRoot(): Make current node a root node.
