Question

这些是我模特中的关系：

Medecine属于许多药理学和药理学属于许多Medecine
Medecine属于许多治疗和治疗属于许多Medecine
Medecine属于许多Galenic和Galenic属于许多Medecine
Medecine属于许多AdministrationMode和AdministrationMode属于许多Medecine
Medecine属于许多ActivePrinciple和ActivePrinciple属于许多Medecine

药理学在所有情况下运作良好且速度更快（loadind是正常的） - ：）

当我在我的控制器中为其他关系执行此类查询时，我的问题就在那里：

$Pharmacologic = Pharmacologic ::Find(1);

$Medecines= $Pharmacologic ->medecines()->orderBy('field1', 'asc')
->paginate(10);

return view('page', compact('Medecines'));

药理和医学支点

Schema::create('pharmaco_medecine', function(Blueprint $table) {
$table->increments('id');
$table->integer('medecine _id')->unsigned(); $table->foreign('medecine _id') ->references('id')->on('tbl_medecine') ->onDelete('cascade');
$table->integer('pharmaco_id')->unsigned(); $table->foreign('pharmaco_id') ->references('id')->on('tbl_pharmaco') ->onDelete('cascade'); });

治疗和医学支点

Schema::create('therapeutic_medecine', function(Blueprint $table) {

$table->increments('id');

$table->integer('medecine_id')->unsigned();
$table->foreign('medecine_id')
      ->references('id')->on('tbl_medecine')
      ->onDelete('cascade');

$table->integer('therapeutic_id')->unsigned();
$table->foreign('therapeutic_id')
      ->references('id')->on('tbl_therapeutic')
      ->onDelete('cascade');

});

Galenic and medecine pivot

Schema::create('gal_medecine, function(Blueprint $table) {

$table->increments('id');

$table->integer('medecine_id')->unsigned();
$table->foreign('medecine_id')
      ->references('id')->on('tbl_medecine')
      ->onDelete('cascade');

$table->integer('gal_id')->unsigned();
$table->foreign('gal_id')
      ->references('id')->on('tbl_gal')
      ->onDelete('cascade');

});

AdministrationMode和medecine pivot

Schema::create('medecine_admin_mode', function(Blueprint $table) {

$table->increments('id');

$table->integer('medecine_id')->unsigned();
$table->foreign('medecine_id')
      ->references('id')->on('tbl_medecine')
      ->onDelete('cascade');
$table->integer('admin_mode_id')->unsigned();
$table->foreign('admin_mode_id')
      ->references('id')->on('tbl_adminmode')
      ->onDelete('cascade');

});

ActivePrinciple和medecine pivot

Schema::create('medecine_active_princip', function(Blueprint $table) {

$table->increments('id');

$table->integer('medecine_id')->unsigned();
$table->foreign('medecine_id')
      ->references('id')->on('tbl_medecine')
      ->onDelete('cascade');

$table->integer('active_princip_id')->unsigned();
$table->foreign('active_princip_id')
      ->references('id')->on('tbl_activeprincip')
      ->onDelete('cascade');

});

该视图生成的数据结果没有任何错误，但仍然几乎可以加载几分钟。我失踪了什么？

Thnx并抱歉这篇长篇文章

模型

MEDECINE

class Medecine extends Model
{
    protected $table='tbl_medecine';


        public function pharmacologics() 
    {

        return $this->belongsToMany('App\Pharmacologic');

    }

            public function therapeutics() 
    {

        return $this->belongsToMany('App\Therapeutic');

    }

                public function galenics() 
    {

        return $this->belongsToMany('App\Galenic');

    }

                public function administrationmodes() 
    {

        return $this->belongsToMany('App\AdministrationMode');

    }

                public function activeprinciples() 
    {

        return $this->belongsToMany('App\ActivePrinciple');

    }
}

药理学

class Pharmacologic extends Model
{
    //
    protected $table='tbl_pharmacologic';

    public function medecines() 
    {

        return $this->belongsToMany('App\Medecine');

    }
}

等等......
