This GEM allows to call methods lazily. The actual work will not be performed until the result is used. There's no promise/force semantics, just a single call (or block) is stored and executed the first time the (lazy) result is accessed.
user = User.lazy.find(:first) # will not access a db
puts user.name # this will actually perform the find and then get the name from
# the result
user_name = User.lazy { |user| user.find(:first).user_name } # no db access
puts user_name # db will be accessed here
- Fork the project.
- Make your feature addition or bug fix.
- Add tests for it. This is important so I don't break it in a future version unintentionally.
- Commit, do not mess with rakefile, version, or history. (if you want to have your own version, that is fine but bump version in a commit by itself I can ignore when I pull)
- Send me a pull request. Bonus points for topic branches.
