Rails effective way of looping through daterange - ruby-on-rails

Question

I have ScheduleDay model as;
=> #<ActiveRecord::Relation [#<ScheduleDay id: 1, from: "2017-01-21 00:00:00", to: "2017-01-30 00:00:00", weekday: 100, weekend: 200, weekly: 90, available: true, check_in: "09:00", check_out: "18:00", min_stay: 2, sevendays: false, check_in_day: nil, created_at: "2017-01-14 11:25:18", updated_at: "2017-01-14 11:27:00">, #<ScheduleDay id: 2, from: "2017-02-05 00:00:00", to: "2017-02-15 00:00:00", weekday: 150, weekend: 200, weekly: 140, available: nil, check_in: "09:00", check_out: "18:00", min_stay: 3, sevendays: false, check_in_day: nil, created_at: "2017-01-14 15:53:21", updated_at: "2017-01-14 15:54:43">, #<ScheduleDay id: 3, from: "2017-03-15 00:00:00", to: "2017-06-15 00:00:00", weekday: nil, weekend: nil, weekly: nil, available: false, check_in: nil, check_out: nil, min_stay: 1, sevendays: false, check_in_day: nil, created_at: "2017-01-14 15:56:01", updated_at: "2017-01-14 15:56:57">, #<ScheduleDay id: 4, from: "2017-08-05 00:00:00", to: "2017-09-30 00:00:00", weekday: 500, weekend: 500, weekly: 500, available: true, check_in: "09:00", check_out: "18:00", min_stay: 7, sevendays: true, check_in_day: "Saturday", boat_id: nil, created_at: "2017-01-14 16:01:00", updated_at: "2017-01-14 16:02:10">]>
I have another date range and I would like to loop over my date range in ScheduleDay table and if record is found get some data. If not found then get data as well. I tried couple different way but I m looking for the most efficient way in ruby.
first = Date.parse("05.2.2017")
last = (Date.parse("16.2.2017"))
schedules = ScheduleDay.where(from: Date.today..(last+1.day))
dates = []
(first..last).each do |date|
flag = 0
catch :date_found do
schedules.each do |s|
(s.from.to_date..s.to.to_date).each do |d|
puts date
puts d
if date == d
flag += 1
puts 'found'
throw :date_found
end
end
end
if flag == 0
puts 'date not found'
end
end
end
This is what I have tried so far. But the problem here is I can not access the record if it is not found. If I take;
if flag == 0
puts 'date not found'
end
inside schedules.each... loop then it prints not found for every record in ScheduleDay. I want to loop through all ScheduleDay record and if not found get some data.
EDIT:
I have database records saved by the user. User can customize any date of the year by selecting date range and pricing. I ask user base pricing as well.
So, lets say user entered 15.01.2017 & 21.01.2017 custom price: 100 and base price 200 (base price will be used if date is not found on database date-range).
I would like to return json array of February. So I need;
01.01.2017 -> custom price exists? if not get base price
02.01.2017 -> custom price exists? if not get base price
...
15.01.2017 -> yes! custom price exists get custom price
16.01.2017 -> yes! custom price exists get custom price
17.01.2017 -> yes! custom price exists get custom price
18.01.2017 -> yes! custom price exists get custom price
...
21.01.2017 -> yes! custom price exists get custom price
...
31.01.2017 -> custom price exists? if not get base price
then create json
EDIT2
What if I use;
first = Date.parse("05.2.2017")
last = Date.parse("16.2.2017")
(first..last).each do |date|
schedules.each do |s|
d2 = (s.from.to_date..s.to.to_date)
puts d2 === date
puts d2
puts date
end
end
=== checks date is in the range.
