How to add validation for date with format mm/dd/yyyy inside model rails 4?

Question

How can I add validation for a date with format mm/dd/yyyy inside model rails 4 ?

So, I only want a date with the format mm/dd/yyyy created inside model.

How do I do that?

Answer 1

validates_format_of :date_of_birth, :with => /\d{2}\/\d{2}\/\d{4}/, :message => "^Date must be in the following format: mm/dd/yyyy"

这是另一种方法。
