You can pass parameters to I18n t
method:
# Example config/locales/en.yml
en:
page:
users: "%{users_count} users currently online"
# In models, controller, etc...
I18n.t('page.users', users_count: 12)
# In views
# ERB
<%= t('page.users', users_count: 12) %>
#SLIM
= t('page.users', users_count: 12)
# Shortcut in views - DRY!
# Use only the dot notation
# Important: Consider you have the following controller and view page#users
# ERB Example app/views/page/users.html.erb
<%= t('.users', users_count: 12) %>
And get the following output:
"12 users currently online"
