Laravel 具有多态关系的全局访问

Question

In my application I have two columns employable_id && employable_type in almost every table, which are used for storing the information about the user who has created the record.

Something like this:

subscribers:                          products:
------------------------------------  ------------------------------------
id | employable_id | employable_type  id | employable_id | employable_type
------------------------------------  ------------------------------------
 1 |             1 | App\Company       1 |             1 | App\Company
 2 |             1 | App\Company       2 |             1 | App\Employee
 3 |             1 | App\Employee      3 |             3 | App\Employee
 4 |             1 | App\Employee      4 |             8 | App\Employee     and more...

Subscriber.php

class Subscriber extends Model
{
    /**
     * Polymorphic relations
     */
    public function employable()
    {
        return $this->morphTo();
    }
}

I have created an accessor to combine polymorphic relationship's columns, which is working fine.

class Subscriber extends Model
{
    /**
     * Polymorphic relations
     */
    public function employable()
    {
        return $this->morphTo();
    }

    /**
     * Accessor
     */
    public function getAddedByAttribute()
    {
        return $this->employable->name . ' [ ' . $this->employable->designation . ' ]';
    }
}

class Product extends Model
{
    /**
     * Polymorphic relations
     */
    public function employable()
    {
        return $this->morphTo();
    }

    /**
     * Accessor
     */
    public function getAddedByAttribute()
    {
        return $this->employable->name . ' [ ' . $this->employable->designation . ' ]';
    }
}

I am trying to make the getAddedByAttribute method global instead of adding in every model class.

How can I do that..?

Answer 1

you can make a trait and use it in every model need this function
