Why is the request not working in kohane orm?

Question

Kohana

$places = ORM::factory('place');
 $places -> find_all();

Generates a query but returns no data. What could be the problem ?
And this is how it works:
$places = ORM::factory('place')->find_all();

Answer 1

In the first case, probably, the second line should be something like $places = $places->find_all();, because you need to put the result into some variable.
Let's analyze it in the course: it
ORM::factory('place')returns an ORM object. You put it in a variable $places. Then you call the method find_all(), but don't assign the result anywhere.
In the second case, you put the result of the method find_all()into a variable.

Answer 2

$places = ORM::factory('place');
$places_array = $places -> find_all();
var_dump($places_array);
In the first option, you simply did not assign the result to a variable as in the second.
