我有一个Ruby on Rails应用程序,您可以在其中创建'posts'。我开始使用脚手架生成器来生成标题,这是一个字符串,而内容是主体。在Ruby on Rails中更改参数[:id]
每个“交”具有ID的URL,例如,/ 1,/ 2,/ 3等
是否有一种方法来改变它的generater随机字符和数字的字符串,用于例如/ 49slc8sd,/ l9scs8dl等?
以下是我对posts_controller.rb
class PostsController < ApplicationController
# GET /posts
# GET /posts.json
def index
@posts = Post.all
respond_to do |format|
format.html # index.html.erb
format.json { render json: @posts }
end
end
# GET /posts/1
# GET /posts/1.json
def show
@post = Post.find(params[:id])
respond_to do |format|
format.html # show.html.erb
format.json { render json: @post }
end
end
# GET /posts/new
# GET /posts/new.json
def new
@post = Post.new
respond_to do |format|
format.html # new.html.erb
format.json { render json: @post }
end
end
# GET /posts/1/edit
def edit
@post = Post.find(params[:id])
end
# POST /posts
# POST /posts.json
def create
@post = Post.new(params[:post])
respond_to do |format|
if @post.save
format.html { redirect_to @post, notice: 'Post was successfully created.' }
format.json { render json: @post, status: :created, location: @post }
else
format.html { render action: "new" }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# PUT /posts/1
# PUT /posts/1.json
def update
@post = Post.find(params[:id])
respond_to do |format|
if @post.update_attributes(params[:post])
format.html { redirect_to @post, notice: 'Post was successfully updated.' }
format.json { head :no_content }
else
format.html { render action: "edit" }
format.json { render json: @post.errors, status: :unprocessable_entity }
end
end
end
# DELETE /posts/1
# DELETE /posts/1.json
def destroy
@post = Post.find(params[:id])
@post.destroy
respond_to do |format|
format.html { redirect_to posts_url }
format.json { head :no_content }
end
end
end
这里是我在post.rb
模型
class Document < ActiveRecord::Base
attr_accessible :content, :name
end
您能否重新解释一下这个问题?我不确定你在问什么。这可能意味着六十件事情(我可以从头顶开始思考)。 – omninonsense
我已经为你改写过。希望它更有意义。 – user1658756
