Difficulty allocating dynamic URLs to pages from database - ruby-on-rails

Question

I have a large number of mostly static pages which I've put into a database. I'm trying to retrieve these and dynamically generate a URL (similar to this: http://railscasts.com/episodes/117-semi-static-pages-revised. My model:
class Page < ActiveRecord::Base
validates_uniqueness_of :permalink
def to_param
permalink
end
end
Pages Controller:
class PagesController < ApplicationController
before_action :set_page, only: [:show, :edit, :update, :destroy]
# GET /pages
# GET /pages.json
def index
#pages = Page.all
end
# GET /pages/1
# GET /pages/1.json
def show
#page = Page.find_by_permalink!(params[:id])
end
# GET /pages/new
def new
#page = Page.new
end
# GET /pages/1/edit
def edit
#page = Page.find_by_permalink!(params[:id])
end
# POST /pages
# POST /pages.json
def create
#page = Page.new(page_params)
respond_to do |format|
if #page.save
format.html { redirect_to #page, notice: 'Page was successfully created.' }
format.json { render :show, status: :created, location: #page }
else
format.html { render :new }
format.json { render json: #page.errors, status: :unprocessable_entity }
end
end
end
# PATCH/PUT /pages/1
# PATCH/PUT /pages/1.json
def update
respond_to do |format|
if #page.update(page_params)
format.html { redirect_to #page, notice: 'Page was successfully updated.' }
format.json { render :show, status: :ok, location: #page }
else
format.html { render :edit }
format.json { render json: #page.errors, status: :unprocessable_entity }
end
end
end
# DELETE /pages/1
# DELETE /pages/1.json
def destroy
#page.destroy
respond_to do |format|
format.html { redirect_to pages_url, notice: 'Page was successfully destroyed.' }
format.json { head :no_content }
end
end
private
# Use callbacks to share common setup or constraints between actions.
def set_page
#page = Page.find(params[:id])
end
# Never trust parameters from the scary internet, only allow the white list through.
def page_params
params.require(:page).permit(:name, :permalink, :content)
end
end
Routes:
resources :pages, except: :show
resources :products
root to: 'products#index'
get ':id', to: 'pages#show', as: :page
I know there have been some updates on the way that rails generates scaffolds but I just can;t work out what needs to change to make this work? I'm getting errors thrown up both the routes, but was previously getting an error with #page = Page.find_by_permalink!(params[:id])as well. It was saying that the method was missing but I couldn't see how. I also know I could use something like refinerycms but I really want to try and learn this stuff so any help much appreciated!
ERRORS FROM ROUTES:
Invalid route name, already in use: 'page' You may have defined two routes with the same name using the `:as` option, or you may be overriding a route already defined by a resource with the same naming. For the latter, you can restrict the routes created with `resources` as explained here: http://guides.rubyonrails.org/routing.html#restricting-the-routes-created
