Returns the Cachetastic::Caches::Base object associated with the object. If a cache hasn‘t been defined the one will be created on the fly. The cache for the object is expected to be defined as: Cachetastic::Cacheable::{CLASS_NAME_HERE}Cache

Example:

  class Person
    include Cachetastic::Cacheable
    attr_accessor :name
    def cachetastic_key
      self.name
    end
  end

 Person.cache_class # => Cachetastic::Cacheable::PersonCache

43:         n = self.class.name
44:         n = self.name if n == "Class"
45:         # puts "n: #{n}"
46:         c_name = "Cachetastic::Cacheable::#{n}Cache"
47:         unless Cachetastic::Cacheable.const_defined?("#{n}Cache")
48:           # puts "we need to create a cache for: #{c_name}"
49:           eval %{
50:             class #{c_name} < Cachetastic::Caches::Base
51:             end
52:           }
53:         end
54:         c_name.constantize
55:       end

How much did I want to call this method cache?? It originally was that, but in Rails 2.0 they decided to use that name, so I had to rename this method. This method will attempt to get an object from the cache for a given key. If the object is nil and a block is given the block will be run, and the results of the block will be automatically cached.

Example:

  class Person
    include Cachetastic::Cacheable
    attr_accessor :name
    def cachetastic_key
      self.name
    end
    def always_the_same(x,y)
      cacher("always_the_same") do
        x + y
      end
    end
  end

Person.new.always_the_same(1,2) # => 3 Person.new.always_the_same(2,2) # => 3 Person.new.always_the_same(3,3) # => 3 Person.cacher("always_the_same") # => 3 Person.get_from_cache("always_the_same") # => 3 Cachetastic::Cacheable::PersonCache.get("always_the_same") # => 3

Person.cacher("say_hi") {"Hi There"} # => "Hi There" Person.get_from_cache("say_hi") # => "Hi There" Cachetastic::Cacheable::PersonCache.get("say_hi") # => "Hi There"

88:         cache_class.get(key) do
89:           if block_given?
90:             res = yield
91:             cache_class.set(key, res, expiry)
92:           end
93:         end

Expires the entire cache associated with this objects‘s cache.

Example:

  class Person
    include Cachetastic::Cacheable
    attr_accessor :name
    def cachetastic_key
      self.name
    end
  end

  Person.set_into_cache(1, "one")
  Person.get_from_cache(1) # => "one"
  Person.expire_all
  Person.get_from_cache(1) # => nil
  Person.set_into_cache(1, "one")
  Person.get_from_cache(1) # => "one"
  Cachetastic::Cacheable::PersonCache.expire_all
  Person.get_from_cache(1) # => nil
