 Post.all.includes(:user, :original => {:favorite, :comments => :author })

but it doesn't work , i get error 

syntax error, unexpected ',', expecting => ...(:user, :original => [{:favorite, :comments => :author}... ...

As the error suggests, it's just a syntax error. You've used {:favorite, :comments => :author} which is not a valid Hash.

Use an array as the value for :original to do what you want:

Post.includes(:user, :original => [:favorite, :comments => :author]).all

Your confusion might stem from the omission of some curly braces for Hashes which are not required in all cases. Re-writing the above with the curly braces explicitly added might make it more clear:

Post.includes(:user, {:original => [:favorite, {:comments => :author}]}).all
