For a personal project I’m working on, I need to find out the smallest time period with more than 5 records. I essentially wrote this code:
period = [1.week, 1.month, 1.year].select_first do |period|
Record.where("published_at >= ?", period.ago).count >= 5
end
only to find out that the select_first method doesn’t exist. So I wrote it:
module Enumerable
def select_first(&predicate)
self.each do |item|
if yield(item)
return item
end
end
return nil
end
end
and then of course, I tested it:
require "test_helper"
require "enumerable_extensions"
class EnumerableTest 2 }
end
should "select_first the first one" do
assert_equal 1, [1, 2, 3, 4].select_first { |i| i >= 1 }
end
should "select_first the last one" do
assert_equal 4, [1, 2, 3, 4].select_first { |i| i >= 4 }
end
should "select_first none" do
assert_equal nil, [1, 2, 3, 4].select_first { |i| i >= 100 }
end
end
I’ve heard or read that Hugh Laurie is having some problems in his leg by having to fake a gimp all the time by acting as House. I think I’ve got a solution, it’s not cheap but it’s cheaper than having the actor not being able to perform anymore:
