我试图将一个现有项目从sqlite3库更改为postgresql库，但最后一个错误我不知道如何解决

以下html文件中的blog_路径启动未定义的方法“blog_路径”错误

<!DOCTYPE html>
<html>
    <head>
        <title>My Blog</title>
        <link href="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/css/bootstrap.min.css" rel="stylesheet" integrity="sha384-WskhaSGFgHYWDcbwN70/dfYBj47jz9qbsMId/iRN3ewGhXQFZCSftd1LZCfmhktB" crossorigin="anonymous">
    </head>
    <body>
        <h1>My Blogs</h1>
        <div class="main">
            <div class="left-block">
            </div>
            <div class="blog-container">
                <% @blogs = @blogs.reverse %>
                <% @blogs.each do |blog| %>
                    <div class="blog">
                        <p class="title"><%= blog.title %></p>
                        <p class="time"><%= blog.created_at %></p>
                        <%= link_to 'Learn More', blog_path(blog), class: "btn btn-info" %>
                    </div>
                <% end %>
            </div>
            <div class="right-block">
            </div>
        </div>
        <footer>
            <%= link_to 'New Blog', '/blogs/new', class: "btn btn-primary" %>
        </footer>
    </body>
</html>

这是blogs_controller.rb

class BlogsController < ApplicationController
    def index
        @blogs = Blog.all
    end

    def new
        @blog = Blog.new
    end

    def create
        @blog = Blog.new(blog_params)
        if @blog.save
            redirect_to blogs_url
        else
            render 'new'
        end
    end

    def show
        @blog = Blog.find(params[:id])
    end

    def edit
        @blog = Blog.find(params[:id])
    end

    def update
        @blog = Blog.find(params[:id])
        @blog.update_attributes(blog_params)

        redirect_to blogs_url
    end

    def destroy
        @blog = Blog.find(params[:id])
        @blog.destroy
        redirect_to blogs_url
    end

    private
        def blog_params
            params.require(:blog).permit(:title, :content)
        end

end

class BlogsController


**请告诉我是否需要任何其他资源来解决此问题。
您应该在路由文件中使用资源：blogs
，而不是单独定义每个路由
这里有更多非常感谢！它修复了它。这是一个额外的问题，但是如果我想将url设置为“用户#索引”的“注册”，我需要显式地指定它，对吗？
