Rails3 - Caching in development mode with Rails.cache.fetch

Question

In development, the following (simplified) statement always logs a cache miss, in production it works as expected:

@categories = Rails.cache.fetch(\"categori         


        

Answer 1

Try placing the following in /config/environments/development.rb:

# Temporarily enable caching in development (COMMENT OUT WHEN DONE!)
config.action_controller.perform_caching = true

Additionally, if your cache store configuration is in /config/environments/production.rb, then you will need to copy the appropriate line into development.rb as well. For example, if your cache store is the Dalli memcache gem:

# copied from production.rb into development.rb for caching in development
config.cache_store = :dalli_store, '127.0.0.1' 

Hope that helps.
