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

When you try to access a function in the model as a variable, laravel assumes you're trying to retrieve a related model. They call them dynamic properties. What you need instead is a custom attribute.

Laravel 6 docs: https://laravel.com/docs/6.x/eloquent-mutators

add following method to your model:

public function getLowestAttribute()
{
    //do whatever you want to do
    return 'lowest price';
}

Now you should be able to access it like this:

Product::find(1)->lowest;
