How to embed Ruby code in Rails i18n yml file?

I want to create a sentence that can be singular or plural based on the count parameter:

# When count is 1
"This profile still contains 1 post"

# When count is 2
"This profile still contains 2 posts"

Using Rails i18n mechanism, I believe I have to embed Ruby code to get the correct pluralization for the word "post". I'm trying to build it like this, but it's not working:

# config/locales/en.yml
en:
  message: "This profile still contains %{count} <%= Post.model_name.human(count: count).lowercase %>"

# Output of I18n.translate(:message, count: 2)
"This profile still contains 2 <%= Post.model_name.human(count: count).lowercase %>"

I already tried <%= %>, %{ }, #{ } and {{ }} and all failed.

Is it even possible to embed Ruby code in i18n file? How?

Use the pluralize method :

config/locales/en.yml

en:
  message: "This profile still contains"

view

"#{I18n.t('message')} #{Post.count} #{Post.model_name.human.pluralize(Post.count).downcase}."

#=> output : "This profile still contains 1 post." or "This profile still contains XX posts"

It works but i recommend you to put all the view logic in a helper.

Note : i use global Post.count for the example but you can use any count you want as user.posts.count etc...

According to the docs, you should do something like this:

en:
  message:
    one: This profile still contains 1 post
    other: This profile still contains %{count} posts

And call it:

I18n.t('message', count: count)

Hope it helps!
