I am trying to create an array of dates using loop. But the loop is only pushing one date and when I query an array I see it's not an array, rather a list. Help.
date1 = '01-01-2019'.to_date
dates = []
count = 0
repeat = 3
while (count < repeat)
count += 1
date2 = date1 + count.month
dates << date2
puts dates
end
Expected results should be [01-02-2019, 01-03-2019, 01-04-2019] .
However, if I use rails console, all I get are the dates in a list. If I raise dates.inspect in controller, I only get 01-02-2019 .
How can I fix this?
From your coding style it seems you're pretty new to Ruby. A more Ruby-like approach would be:
start_date = '01-01-2019'.to_date
repeat = 3
dates = 1.upto(repeat).map { |count| start_date + count.months }
# or
dates = (1..repeat).map { |count| start_date + count.months }
Then to print the dates array use:
puts dates
As far as I can tell, your provided code should work. Keep in mind that puts
prints arrays across multiple lines. If you want to display the contents of the array on a single line use p
instead. The difference is that puts
uses the to_s
method while p
uses the inspect
method. Arrays passed to puts
will be flattened and seen as multiple arguments instead. Every argument will get its own line.
puts [1, 2]
# 1
# 2
#=> nil
p [1, 2]
# [1, 2]
#=> [1, 2]
Replace puts dates
by puts "#{dates}"
. It will print array as expected like [01-02-2019, 01-03-2019, 01-04-2019].
