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?
