Where to write Fluent class code in Laravel?

Question

Laravel

So it goes.
There is documentation , and this section talks about Fluent.
And stupidly inserting code that is not clear at all where to write, where to use.
Damn documentation.
Where to prescribe all these pieces of code?

Answer 1

The fluent interface is a chain of methods in php and is used to more conveniently write requests to php, which is then used.
That is, instead we write it in the form'SELECT name FROM table WHERE 1 = 1'

DB::table('table')->select('name')->where('1', '=', 1);

It can be written anywhere. In fact, Eloquent models represent this very fluid interface.
And most importantly, Fluent is not a class. Fluent is an interface

Answer 2

This is not documentation. Open the real documentation.

Answer 3

I'm not a telepath, but it looks like you're going the wrong way.
Look at https://laravel.ru/docs/v5/eloquent
