Trying to get nested objects to be given parent ids

Alright, So I have days, tracks, and events. When I create a track, it is given the proper day_id along with its own track_id . When I try to create an event, I want it to be given the appropriate day_id and/or track_id.

So when I pull up a day it should only show the tracks and events that as associated with the day. An event should exist in a track, which exists in a day.

So, this is basically a calendar that shows a daily schedule of different tracks, and the events within the tracks.

Also, my events table in my db has a track_id and a day_id.

Here is my routes.rb

      resources :days do
        resources :tracks do
           resources :events
         end
       end

My new/create methods from my events_controller.rb

      def new
        @day = Day.find(params[:day_id])
        @track = Track.find(params[:track_id])
        @new_event = Event.new
      end

      def create 
        @day = Day.find(params[:day_id])
        @track = Track.find(params[:track_id])
        @events = @track.events
        @new_event = Event.new(params.require(:event).permit(:name,:start_time, :end_time))


        if @new_event.save
          flash[:notice] = "Saved"
          redirect_to @day
        else
          flash[:error] = "Error"
          render :new
          end
        end

And here is where I am trying to create a new event in my events.new.html.erb

    <%= form_for [@day, @track, @new_event] do |f| %>
    <%= f.label :name %>
    <%= f.text_field :name, class: 'form-control', placeholder: "Enter the event" %>

    <%= f.label :start_time %>
    <%= f.text_field :start_time, class: 'form-control', placeholder: "Enter a start time"%>

    <%= f.label :end_time %>
    <%=f.text_field :end_time, class: 'form-control', placeholder: "Enter a start time"%>
    <%= f.submit "Save", class: 'btn btn-success' %>
    <% end %> 

Thanks for the help, I'm pretty sure I attached everything that was needed!
