Rails.root:/家庭/ ubuntu的/工作區/ yappy/qaucky)
個資源:文章
root 'pages#home'
get 'about', to: 'pages#about'
我new.html.erb文件:
<h1>Create an article</h1>
<%= form_for @article do |f| %>
<% end %>
我的文章控制器文件: 類ArticlesController < ApplicationController的
def new
@article = Article.new
end
end
我article.rb文件:
class Article
end
我的routes.rb文件:
Rails.application.routes.draw do
# The priority is based upon order of creation: first created -> highest
priority.
# See how all your routes lay out with "rake routes".
# You can have the root of your site routed with "root"
# root 'welcome#index'
resources :articles
root 'pages#home'
get 'about', to: 'pages#about'
# Example of regular route:
# get 'products/:id' => 'catalog#view'
我得到一個錯誤,指出:#新 找不到表「文章」這是給我看我的文章控制器文件 的ActiveRecord :: StatementInvalid在ArticlesController:類ArticlesController
錯誤消息'找不到表「articles''是相當具體。沒有數據庫表來存儲您使用表單創建的文章。只需創建一個數據庫遷移,添加所需的表和列並運行它。請參閱[關於遷移的Rails指南](http://edgeguides.rubyonrails.org/active_record_migrations.html)。 – spickermann
我想從用戶界面的文章將這仍然工作 –
