FindCache
It is simply a thread-safe ActiveRecord object caching gem using Rails.cache methods.
It makes “ActiveRecord ‘find_by_id, find_by_(attr)’ methods and ‘has_one, belongs_to’ relations” cacheable by PrimaryKey(PK) or any referenced columns using Rails.cache methods. It also supports fetching multiple records using PKs(ids) with find_all_cache method(if cache store supports multiple reads [hint: memcached_store, dalli_store supports.]).
Installation
Add this line to your application’s Gemfile:
gem 'find_cache'
And then execute:
$ bundle
Or install it yourself as:
$ gem install find_cache
For has_one and belongs_to relations
### Sample Models:
class User < ActiveRecord::Base
has_one :user_detail
# to enable has_one caching
find_cache_has_one :user_detail, UserDetail, :user_id
end
class UserDetail < ActiveRecord::Base
belongs_to :user
# to enable belongs_to caching
find_cache_belongs_to :user, User, :user_id
end
For finding a record
user = User.find_cache(id) # fetches from cache
user.user_detail
# fetches from cache if the User model has
# 'find_cache_has_one :user_detail, UserDetail, :user_id'
user = User.find_by_id(id) # fetches from DB
user.user_detail # fetches from DB
For fetching multiple ids
users = User.find_all_cache([1,2,3,4,5])
users_ordered_desc = User.find_all_cache([4,5,1,2,3], 'id DESC')
users_ordered_asc = User.find_all_cache([4,5,1,2,3], 'id ASC')
For fetching a record by attribute
user_detail = UserDetail.find_by_user_id(1) # from db
user_detail = UserDetail.find_cache_by_ref(:user_id, 1) # from cache store
