错误:找不到PostsController的操作'show'"

Question

我一直在学习铁路

http://guides.rubyonrails.org/getting_started.html.

我在控制器中执行保存数据时遇到错误.运行博客时出现的错误是:"找不到PostsController的动作'show'"

**

我的posts_controller.rb代码是

**

class PostsController < ApplicationController
def new
end
def create
@post=Post.new(params[:post].permit(:title,:text))
@post.save
redirect_to @post
end

private
def post_params
params.require(:post).permit(:title,:text)
end

def show
@post=Post.find(params[:id])
end
end

**

我的show.html.rb代码是

**

<p>
<strong> Title:</strong>
<%= @post.title %>
</p>
<p>
<strong> Text:</strong>
<%= @post.text %>
</p>

**

create_posts.rb的代码

**

class CreatePosts < ActiveRecord::Migration
  def change
    create_table :posts do |t|
      t.string :title
      t.text :text

      t.timestamps
    end
end

请帮我解释为什么会出现这个错误

Answer 1

PostsController#show 方法应该是公开的.

class PostsController < ApplicationController
  def new
  end

  def create
    @post=Post.new(params[:post].permit(:title,:text))
    @post.save
    redirect_to @post
  end

  def show
    @post=Post.find(params[:id])
  end

private

  def post_params
    params.require(:post).permit(:title,:text)
  end

end
