Rails cache with settings

This project started as a fork of cache_with_locale. Besides the locale I also needed the current currency as part of our cache keys. So this gem automatically adds the current locale (I18n.locale) and currency (MoneyRails.default_currency) as parts of caching keys in Rails views.

Problem & Solution

For example you have:

• Rails app with different locales and currencies
• you want to add fragment caching in views

When you add locales and currencies to your cache keys:

  = cache [@user, I18n.locale, MoneyRails.default_currency] do
    = render @user

As you see you need to add I18n.locale and MoneyRails.default_currency as a part of the cache key. And you need to do it everywhere. What if you forget about it in some view?

This gem is a simple solution which allows you to DRY your code. So now you can write

  = cache @user do
    = render @user

And let gem handle all work. You don't need to specify locale as a cache sufix/prefix.

Usage

Just add this gem to your Gemfile.

Installation
