public function scopeCountPivot($query, $pivotTable) { return $query->whereHas($pivotTable, function ($query) { $query->where('column', 'value'); })->count(); } } 在上述示例中,我们定义了一个名为CountPivot的作用域方法,接受一个参数$pivotTable,表示数据透视表的表名。在作用域方法中,...

// 获取中间表字段, 通过 pivot 属性 $user= App\User::find(1); foreach($user->rolesas$role) { echo$role->pivot->created_at; } // 当 pivot 表包含额外的属性时, 必须定义关联时先指定 return$this->belongsToMany('App\Role')->withPivot('column1','column2'); // 自动包含created_at ...
是指在Laravel框架中使用Eloquent关联模型时,通过wherePivot方法来对中间表的字段进行查询筛选的功能。 作用域查询wherePivot可以用于多对多关联关系中的中间表,通过指定wherePivot方法的参数来对中间表的字段进行条件筛选,从而获取符合条件的关联模型。 具体使用方法如下: 在定义多对多关联关系的模型中,使用withPivot方法...

Eloquent provides some very helpful ways of interacting with this table. For example, let's assume our User object has many Role objects that it is related to. After accessing this relationship, we may access the pivot table on the models:$user = User::find(1); foreach ($user->roles ...
protected $table = 'my_flights'; 更换主键名称 protected $primaryKey = 'id'; 注意: Eloquent 默认主键字段是自增的整型数据, 这意味着主键将会被自动转化为 int 类型, 如果你想要使用非自增或非数字类型主键, 必须在对应模型中设置 $incrementing 属性为 false , 如果主键不是整型, 还要设置 $keyType...
