Rails 2.1 breaks prototype’s responseJSON

by Topper on September 9th, 2008

It appears that a render of json:

render :json => {:blah => “hi”}.to_json

Is responding with a mime type of text/json instead of the previous application/json

The latest version of prototype (and previous versions) specifically looks for application/json in order to fill the responseJSON property of the response object.

  • Registering a mimetype will fix it:
    Mime::Type.register “application/json”, :json
