How can I get current year in Ruby on Rails?
I tried a variety of things, including
The problem is they return the previous year in cases where year changes after launching the server (eg. after new year's).
Relevant code:
Model brewery.rb
class Brewery < ActiveRecord::Base
...
validates :year, numericality: { only_integer: true, less_than_or_equal_to: Date.today.year }
...
Problem occurs when creating a new brewery, so I assumed Date.today.year would be evaluated whenever that action takes place.
In your example, Date.today.year is evaluated only once when the application is started and the class is loaded and therefore doesn't change any more later on.
But when you use a lambda in your validator declaration, then the lambda is evaluated each time when the validation is checked for that attribute:
validates :year, numericality: {
only_integer: true,
less_than_or_equal_to: ->(_brewery) { Date.current.year }
}
Furthermore, I suggest using Date.current instead of Date.today because the current method pays attention to timezone settings.
