Laravel how to add a custom function in an Eloquent model?

Question

I have a Product model

class Product extends Model
{
    ...

    public function prices()
    {
        return $this->hasMany(\'App\\Price\');
    }

            


        

Answer 1

Use Eloquent accessors

public function getLowestAttribute()
{
    return $this->prices->min('price');
}

Then

$product->lowest;
