使用render => json时出错

Question

I have the following in my controller. My requirement is to populate the second drop down based on the input from the 1st drop down.

def  update_releases 
 puts "inside func"
 project = Project.find(params[:project_id]) 
 @releases = project.releases
 puts "releases==#{releases}"
 render :json => @releases.map{|c| [c.id, c.name]} 
end 

I am getting the error:

Started GET "/javascripts/jquery-ujs.js" for 172.30.11.164 at Thu Oct 20 14:22:06 +0530 2011

ActionController::RoutingError (No route matches "/javascripts/jquery-ujs.js"):

Kindly help me out here.

Thanks, Ramya.

You are trying to include the file jquery-ujs.js which doesnt exist. Either you include a file that requires the jquery-ujs.js or you try it directly. Change your app/views/layout/application.html.erb and set the correct filename to include jquery.
