Question

我正在使用laravel 5.7

当我使用whereHas检查关系的存在时，我遇到Unknown column "has" in 'where clause错误！为什么？

这是我的代码：

$query->whereHas('departures', function ( $query) {
    $query->whereBetween('depart_date', [date($this->data['departFrom_date']), date($this->data['departTo_date'])]);
});

这是我的模型部分：

    public function departures()
    {
        return $this->hasMany(CruiseSailingDepartures::class);
    }

更新：

查询始于：

$query = DB::table('table_name');

Answer 1

将外键和本地键放在关系中。

public function departures()
{
    return $this->hasMany('App\Model\CruiseSailingDepartures','foreign_key','local_key');
}

$res = BaseModel::find($id);
foreach($res->departures as $departures)
{
  echo $departures->name; //whatever field you have in CruiseSailingDepartures table
}

Answer 2

$model = YourModel::with('departures')->whereHas('departures', function($query) use ($this) {
    $query->whereBetween('depart_date', [date($this->data['departFrom_date']), date($this->data['departTo_date'])]);
})->get();

Answer 3

我发现了问题，我在使用DB::table('tablename')而不是模型（TableName:: ...）

感谢所有答案

“ where”子句中的未知列“ has”
