用于一对多的Laravel 5模型方法,其中许多表使用主键超过两次

I have one table called gen_nodes, which is a root table in that it has an id, fields for name and description, and each row is not dependent on another value.

I also have a table called gen_nodes_hierarchy which has three columns:

parent_node_id   (required)
child_node_id    (required)
group_node_id    (default NULL, optional)

Where the values in gen_nodes.id will reside.

To give an overview of use, these two tables are for defining complex taxonomic relationships including menu hierarchies.

I am new to this area of Laravel (5.5). What is the proper way to set up the model(s) for these tables, and what properties need to be declared in each model to make this work? Thanks.
