Question

I am trying to run a javascript line from my controller as a response to an AJAX call :

respond_to do |format|
  if params[:return_to] == 'monthly_calendar'
    render js: "alert('hey Trip!');"
  else
    format.js   { render :partial => @task, layout: false }
    format.html { redirect_to things_url }
    format.json { render :json => @object.to_json }
    format.xml do
      if @task.new_record?
        render :xml => @task.errors.to_xml
      else
        render :xml => @task.to_xml, :status => '201 Created'
      end
    end
  end

Instead this returns a 406. Any ideas?

It most certainly goes to the correct call in this statement. But doesn’t know what to do with the javascript call, and returns a 406.

Change it to this

respond_to do |format|
   if params[:return_to] == 'monthly_calendar'
      format.js { render js: "alert('hey Trip!');" }
   else
  .....

Because you are not specifying to what format are you responding, e.g. format.html { #your code here } when params[:return_to] == ‘monthly_calendar’. Check documentation of respond_to for more information.
