node-categoires's Issues

php artisan node-categories:migration

SQLSTATE[42000]: Syntax error or access violation: 1071 Specified key was too long; max key length is 3072 bytes (SQL: alter table categories add index categories_node_index(node))

:(

提两个trait NodeCategoryTrait的问题

第一个:
public function parent() { return $this->belongsTo(self::class, 'parent_id', 'id'); }
这里的self 应该不能这么用吧 应该改成static吧,不然指向的是NodeCategoryTrait本身,而不是model本身。
第二个:
public function parents() { return $this->where(DB::raw("LOCATE(node, '{$this->node}')"), '>', 0) ->where('id', '<>', $this->id)->get(); }
这个的实现方式没有必要吧
public function parents() { $node_array = explode(',',$this->node); return $this->whereIn("id",$node_array)->where('id', '<>', $this->id)->get(); }
讲道理这样的效率会高很多吧。

trait NodeCategoryTrait问题

再来个
public function childrens() { return $this->where('node', 'like', $this->node.'%')->get(); }

这个忘了把自己去除掉吧,应该是
public function childrens() { return $this->where('node', 'like', $this->node.'%')->->where('id', '!=', $this->id)->get(); }
