Get X days out of an Array

Question:

Tag: ruby,ruby-on-rails-4

I have an array filled with Datetime objects:

[Mon, 22 Jun 2015, Tue, 23 Jun 2015, Wed, 24 Jun 2015, Thu, 25 Jun 2015, Fri, 26 Jun 2015, Sat, 27 Jun 2015, Sun, 28 Jun 2015]

I know how to select what I want from the array ex:

week.select{|x|x.monday? || x.wednesday?}

But now when I try to write a method to select days from the array, I can't seem to figure out how to pass these methods to the select statement:

ex:

def get_days(wkn, desired_days*)
get_week = Model.week(2)
get_days_of_week = get_week.select{|x|x.desired_day[monday]?|| x.desired_day[sunday]} 
end

any ideas?

desired_days would be a user saying that they want mon. and sun. so mon, sun will get passed in as desired_days the method will get a full week range and then I want select out the desired days.


Answer:

I would do:

def get_days(wkn, *desired_days)
  get_week = Model.week(2)
  get_days_of_week = get_week.select { |x| desired_days.include? x.strftime("%A") }
end
