Laravel: why does this cause error - call to undefined method?

Why calling a method with parenthesis in a template causes error, but without doesn't? How would I pass a parameter then?

Error:

Call to undefined method Illuminate\Database\Query\Builder::test()

index.blade.php

...
<p class="product-price-old"><s>{{ $product->test("123") }}</s></p>
...

Product.php

...
public function getTestAttribute($value)
{
    return $value;
}
...

but if I do something like this it works fine:

index.blade.php

...
<p class="product-price-old"><s>{{ $product->test }}</s></p>
...

Product.php

...
public function getTestAttribute()
{
    return "123";
}
...

If you are assigning an instance of Product.php (which should be a model of a product table in your database) to a blade variable, and your Product table has a column called 'test' , Then you're just printing that value from your model and the instance of Product.php does not have a test() method in it. You can just retrieve the value of test attribute.

If you want to pass parameters to a function in your model, Use a different name for your function. You can not pass parameters to accessors in Laravel.

The getTestAttribute is accessor, so it's not a real function. It rather shows how you can get attribute of model.

That's why for getTestAttribute method you should use:

$product->test
