之前我使用的是 sqlite3 现在我想换成 mysql 的

我把 database.yml 里面的信息改成了 mysql 之后还需要做什么才可以呢？

提示信息是: The action 'show' could not be found for CommentsController

下面是 Comments 代码

class CommentsController < ApplicationController

http_basic_authenticate_with :name => "admin", :password =>"password" , :only => :destroy

def create @post = Post.find(params[:post_id]) @comment = @post.comments.create(params[:comment]) redirect_to post_path(@post) end

def destroy @url = @post = Post.find(params[:post_id]) @comment = @post.comments.find(params[:id]) @comment.destroy redirect_to post_path(@url) end

end
