嗨，伙计们！ 我在图像上附加了我想在表格中看到的字段。但是，我正在检查刀片模板，可以找到为什么我无法访问该属性的原因。我创建了模型之间的特定关系，但似乎不可能从数据库中提取此信息。
这是模特
class Booking_Stays_Abroad extends Model
{
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'booking__stays__abroads';
/**
* The database primary key value.
*
* @var string
*/
protected $primaryKey = 'id';
/**
* Attributes that should be mass-assignable.
*
* @var array
*/
protected $fillable = [
'id_stays_abroad',
'user_id',
'status',
'departure_date',
'return_date',
'number_weeks',
];
/**
* The attributes that should be mutated to dates.
*
* @var array
*/
protected $dates = [];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [];
/**
* Set and get the departure_date
*
* @param string $value
* @return void
*/
public function setDepartureDateAttribute($value):void
{
$this->attributes['departure_date'] = Carbon::createFromFormat(config('app.date_format'), $value)->format('Y-m-d');
}
public function getDepartureDateAttribute($value)
{
return Carbon::createFromFormat('Y-m-d', $value)->format(config('app.date_format'));
}
/**
* Set and get the return_date.
*
* @param string $value
* @return void
*/
public function setReturnDateAttribute($value):void
{
$this->attributes['return_date'] = Carbon::createFromFormat(config('app.date_format'), $value)->format('Y-m-d');
}
public function getReturnDateAttribute($value)
{
return Carbon::createFromFormat('Y-m-d', $value)->format(config('app.date_format'));
}
public function stays_abroad()
{
return $this->belongsTo(Stays_Abroad::class);
}
public function user()
{
return $this->belongsTo(User::class);
}
}
另一个
class Stays_Abroad extends Model
{
/**
* The database table used by the model.
*
* @var string
*/
protected $table = 'stays_abroads';
/**
* The database primary key value.
*
* @var string
*/
protected $primaryKey = 'id';
/**
* Attributes that should be mass-assignable.
*
* @var array
*/
protected $fillable = [
'location',
'county',
'nation',
'country',
'school',
'accommodation',
'landmarks',
'price_week'
];
/**
* The attributes that should be mutated to dates.
*
* @var array
*/
protected $dates = [];
/**
* The attributes that should be cast to native types.
*
* @var array
*/
protected $casts = [];
/**
* Set the return_date.
*
* @param string $value
* @return void
*/
public function booking_stays_abroad()
{
return $this->hasMany(Booking_Stays_Abroad::class);
}
}
这是刀锋模板

</div>
为简单起见，我想提取属于Stays_Abroad模型的 location 属性，并将其显示在index.blade中。
谢谢。
答案 0 :(得分：0)
您的模型Booking_Stays_Abroad的外键为'id_stays_abroad'。当您在Stays_Abroad模型中像这样返回$ this-> hasMany（Booking_Stays_Abroad :: class）创建关系时，它期望Bookin__Stays__Abroad中的外键类似于'stays_abroad_id'。因此，要么更正另一个表中的外键，要么像
那样明确提及外键public function booking_stays_abroad()
{
return $this>hasMany(Booking_Stays_Abroad::class, 'id_stays_abroad', 'id');
}
