Hello, i have one problem
How do I insert a list from the database in a listbox

Example i trying

$row_user = $db.execute( "SELECT user FROM usuarios" )
$row_user.each do |row|
@users = list_box :items => [row[0]]
end


but I know he has repeated many lists

tried

@users = list_box :items => $row_user

but returns values with ["_"]
