I think because the record with that id is not existed in the database. You could check the database to to see whether there is a record with the id. Or you could also check the id value in the controller, is it valiable?

Hi David This error is mainly because your not getting id in the create function Please follow the following steps, i think this will solve your problem. I hope you configured your routes like this map.resources :courses do |course| course.resources :pages end <%form_for :page,:url=>course_pages_path(@course) do %> <%end%> in controller def new @course = Course.find(params[:course_id]) end def create @course = Course.find(params[:course_id]) @page = @course.pages.find(params[:page]) end Keep rocking!

I Can''t find Story without an ID. This is from my email_controller.rb def correspond user = @current_user story = Story.find(params[:id]) recipient = story.user @title = "Email @current_user.login" if param_posted?(:message) @message = Message.new(params[:message]) if @message.valid? UserMailer.deliver_message( :user => user, :recipient => recipient, :message => @message, :user_url => user, :reply_url => url_for(:action => "correspond", :id => user.login) ) flash[:notice] = "Email sent." redirect_to :action => "index", :controller => "stories" end end end The problem is in the third line.

So possibly params[:id] is not valid. What is the value of params[:id]? Look in development.log to find out. Also have a look at the rails guide on debugging, it will show you how you can use ruby-debug to break into your code and inspect data, so you can see what params[:id] is. In this case the log may be enough though. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
