我有大量静态页面，我已将其放入数据库中。我试图检索这些并动态生成一个网址（类似于：http://railscasts.com/episodes/117-semi-static-pages-revised。我的模型：
class Page < ActiveRecord::Base
validates_uniqueness_of :permalink
def to_param
permalink
end
end
页面控制器：
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
路线：
resources :pages, except: :show
resources :products
root to: 'products#index'
get ':id', to: 'pages#show', as: :page
我知道有关rails生成脚手架的方式有一些更新，但我可以;找出需要改变的内容以使其工作？我在两条路线上都遇到了错误，但之前也遇到了@page = Page.find_by_permalink!(params[:id])的错误。有人说这种方法不见了但我无法理解。我也知道我可以使用像refinerycms这样的东西，但我真的想尝试学习这些东西，所以任何帮助都非常赞赏！
路线错误：
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
