Question

我现在有三个模特

用户

public function languages(){
    return $this->belongsToMany('App\Language');
}

报

public function languages(){
    return $this->belongsToMany('App\Language');
}

语言

public function users(){
    return $this->belongsToMany('App\User');
}

public function newspapers(){
    return $this->belongsToMany('App\Newspaper');
}

我已经拥有language_user，language_newspaper表格

在修补程序中，我已成功通过attach（）blablabla检索这两种关系。

问题是我怎样才能在{1}} {1}}中搜索Newspaper id1具有此User的啰嗦？对我来说这似乎很复杂。

Language

User id1 -> has language en, zh - ＆GT;确定

Newspaper id1 -> has language en, jp - ＆gt;不行

我试过这个，但不确定它是否正确

Newspaper id2 -> has language zh

$where = [];

whereHas

Laravel多对多关系搜索
