带有“LIKE”语句的雄辩查询在Laravel6中不起作用

我正在尝试制作一个用户搜索引擎，它使用一个字符串将其与集合中每个用户的用户名进行比较，并返回那些将该字符串作为其用户名子字符串的搜索引擎，在我的Laravel项目中，我有一个与其自身相关的用户模型，这是一个与pivot表的多对多关系，这些表是通过迁移生成的，下面显示了两种迁移的up方法

创建用户表迁移中的up方法

创建\跟随\表迁移中的up方法

现在，关系在用户模型中定义如下

用户模型

最后，在我的UserController中有以下方法

用户控制器

它与api.php路由文件中定义的以下路由相关

Route::group(["namespace" => "API"], function(){
    Route::get("search_followed/{username}", "UserController@searchFollowed");
}

所有这些都不能正常工作，因为searchFollowered方法返回所有通过lazy-eager加载加载的跟踪用户，而不管方法参数字符串如何。如果我取消对this方法中的注释行的注释，我将获得异常SQLSTATE[23000]：完整性约束冲突：字段列表中的1052列“id”不明确SQL:选择“id”、“usename”、“name”、“lastname”、“follower\u followered”.“follower\u id”作为“pivot\u follower\u id”，'follower\u followered`.'followered\u id`作为'users'内部联接'follower\u followerd`中的'pivot\u followerd'id`.'id`='follower\u followered`.'follower\u id`其中'follower\u followered`.'followered\u id`在1中为'follower\u id'，在'username'中为%%。我希望我的意图是明确的

我试过了，但没用

有人能帮我吗

提前谢谢

$user->load(["followed" => function($query) use ($username) { $query->where('username', 'LIKE', "%{$username}%"); } ]);

希望它能帮助您轻松使用

->其中的'username'，'LIKE'，%{$username}%像这样使用我已经做过了。。。我把。dd$query的输出是什么$用户->加载[跟随=>函数$query使用$username{$query->where'username'，'LIKE'，%{$username}%；}]；=>像这样使用way@AnkitaDobariya哇！那工作，谢谢你！我不需要%{$username}%中的卷发。
