如何使用自定义多态表创建多对多关系?

model_has_tags

$table->increments('id');
$table->integer('tag_id';
$table->string('model_type');
$table->integer('model_id');

标签

$table->increments('id');
$table->string('name');

用户

$table->increments('id');
$table->string('full_name');

我尝试了一下,但是没有用。

标记模型

public function users()
    {
        return $this->morphedByMany(User::class, 'model');
    }

用户模型

public function tags()
    {
        return $this->morphToMany(Tag::class, 'model');
    }

错误:

SQLSTATE[42S02]: Base table or view not found: 1146 Table 'stormport.models' doesn't exist (SQL: select `tags`.*, `models`.`model_id` as `pivot_model_id`, `models`.`tag_id` as `pivot_tag_id`....

如何解决这个问题?
