How to display user age in rails?

Question

Ruby on Rails

I filed the age of the users, now I can’t figure out how to add the correct declination of “years” “years” “year” to them at the end
User.rb

def age
    now = Time.now.utc.to_date
    now.year - birthday.year - (birthday.to_date.change(:year => now.year) > now ? 1 : 0)
  end

I insert into the view
<%= @user.age %>
and what to add so that not only the number is displayed, but it was, for example, 25 years 32 years old?

Answer 1

Rails has a helper for this, but it doesn't work properly with Russian. Look aside https://github.com/yaroslav/russian/
there is an example
Russian::pluralize
Russian::p
Russian.p(1, "thing", "things", "things")
=> "thing"
Russian .p(2, "thing", "things", "things")
=> "things"
Russian.p(10, "thing", "things", "things")
=> "things"
Russian.p(3.14 , "thing", "things", "things", "things") # the last option is used for fractional values
​​=> "things"
in your case will be something like <%= @user.age Russian.p(@user. age, "..

It is better to use the locale and the corresponding API:
rusrails.ru/rails-internationalization-i18n-api
Your case section 4.3
