Turn a partial into a json variable in the controller

Hi I need to turn the html of a partial into a json object (NO开发者_运维问答T TO BE RENDERED), but to be stored in a seperate format.

Something like this:

  @json = (:partial => "/answers/likers" ,:type => :html)

Although the above obviously does not work, but hope you get the point, thanks!

Rails has a .to_json function. However, I never used this together with a partial ...
