三个表和数据透视表之间的关系

Question

我有一些类似capabilities之类的表，其中有group_id存储在capability_groups中。另一个表capability_level和一个数据透视表存储了capabilities_id.capability_level_id。

我想使用作为父级和子级的组获取数组数据，并附带功能级别数据。

Array

                            [title] => asdasd
                            [group_id] => 1
                            [level_id] => 
                            [level_description] => 
                            [created_at] => 2019-07-11 12:28:04
                            [updated_at] => 2019-07-11 12:28:04
                        )

我越来越想要获得功能级别标题（使用ID）到数组。
