Rails 4: Nested objects not saving to database - ruby-on-rails-4

Question

I'm building a forum and I have forum_types that has_many forum_threads. I want to show a list of the different forum threads a forum type has when clicked. I can create a forum thread for a forum type but it's not showing on the forum thread 'index' page (forum_type_forum_threads_path). There is no error, just a blank page where I have placed the loop. I feel like it's something in my forum_threads_controller. If someone could please help me I would appreciate it...thanks in advance.
forum_threads_controller.rb

#forum_threads = ForumThread.all #something not right here

Added/removed some lines in create action of the forum threads controller. Then passed in the "#forum_type" and "forum_thread" after the link_to button in the view.
forum_threads_controller.rb
class ForumThreadsController < ApplicationController
before_action :require_user, except: [:show, :index]
before_action :set_forum_type
before_action :set_forum_thread, except: [:index, :new, :create]
def index
# #forum_threads = ForumThread.all
forum_threads = #forum_type.forum_threads.all.order("#{:created_at} DESC")
end
def show
#forum_post = ForumPost.new
end
def new
#forum_thread = ForumThread.new
#forum_thread.forum_posts.build
end
def create
#forum_thread = #forum_type.forum_threads.new(forum_thread_params)
#forum_thread.user = current_user
#forum_thread.forum_posts.first.user = current_user
if #forum_thread.save
flash[:success] = "Your thread has been created."
redirect_to forum_type_forum_thread_path(#forum_type, #forum_thread)
else
render action: :new
end
end
private
def set_forum_type
#forum_type = ForumType.find(params[:forum_type_id])
end
def set_forum_thread
#forum_thread = ForumThread.find(params[:id])
end
