Question

parent_id always show Null我想以此方式在用户迁移中使用parent_id

  Schema::create('users', function (Blueprint $table) {
        $table->increments('id');
        $table->primary(['id', 'parent_id']);
        $table->string('name');
        $table->string('email')->unique();
        $table->string('password');
        $table->rememberToken();
        $table->timestamps();
    });

如果是这样，我该如何从register.blade.php插入数据并在registercontroller中编辑代码。

 $parentid =????;
     $position = $data['position'];
      $posid =  getLastChildOfLR($parentid,$position);

尝试一下：

Schema::create('users', function (Blueprint $table) {
     $table->increments('id');
     $table->unsignedInteger('parent_id')->nullable(); // root user will have null parent_id
     $table->string('name');
     $table->string('email')->unique();
     $table->string('password');
     $table->rememberToken();
     $table->timestamps();

     $table->foreign('parent_id')->references('id')->on('users')->onDelete('cascade'); // cascade delete children when deleting parent
});

我可以在用户表迁移中使用parent_id吗？
