红宝石错误-无效的日期

Question

I have a date from DB in the following format - '1973-06-15' When I try to create a date object with

dob = DateTime.strptime(user.date_of_birth.to_s, "%Y-%m-%d")

I always get

invalid date

error. Outputting the date normally shows correct date. How to correctly parse dates in this case?

Answer 1

假设user.date_of_birth是一个DateTime（或Date）对象，则应该能够执行以下操作：

dob = user.date_of_birth.strftime("%Y-%m-%d")
