我有一個這樣的數組：Rspec的陣列匹配部分字符串時間戳
["xxxxxxxxx", 448, "2016-08-29", 1, "Trading", 53, "Trading", 2016-06-03 00:00:00 -0500, 2016-06-03 00:00:00 -0500, "RBS", "USD", "United States Dollar", nil, 2016-10-08 00:00:00 -0500, 2016-09-08 00:00:00 -0500, "2016-09-08 00:00:00 -0500","lcz076", nil, 5, 2016-10-08 00:00:00 -0500, 2016-09-08 00:00:00 -0500, "9", 448, "P", nil]
，我需要爲這個值僅"2016-09-08 00:00:00"
我怎麼做匹配值？
首先將所有的日期，Strings
然後之後將其設置爲可變a
a = ["xxxxxxxxx", 448, "2016-08-29", 1, "Trading", 53, "Trading", "2016-06-03 00:00:00 -0500, 2016-06-03 00:00:00 -0500"...
我注意到所有類型的日期你想檢查有-0500這樣你就可以通過在此陣列中循環取出該部分
new_str[i] = str.slice(0..(str.index('-0500')))
現在你可以使用.include?("stuff here")
它總是最後5位數，所以如何切片最後5位而不是 –

假設你有：
a = ["xxxxxxxxx", 448, "2016-08-29", 1, "Trading", 53, "Trading", "2016-06-03 00:00:00 -0500", "2016-06-03 00:00:00 -0500", "RBS", "USD", "United States Dollar", nil, "2016-10-08 00:00:00 -0500", "2016-09-08 00:00:00 -0500", "2016-09-08 00:00:00 -0500", "lcz076", nil, 5, "2016-10-08 00:00:00 -0500", "2016-09-08 00:00:00 -0500", "9", 448, "P", nil]
RSpec的預期應該是：
matches = a.select{ |x| x.to_s.match("2016-09-08 00:00:00") }
expect(matches).not_to be_empty
你只是要檢查它是否是裏面？然後使用'.include？' –
