問題描述

使用rails g controller admin::articles index new edit創(chuàng)建controller，使用rails g model article創(chuàng)建的model。 路由為

namespace :admin do resources :articlesend

/app/controllers/admin/articles_controller.rb

class Admin::ArticlesController < ApplicationController def index @articles = Article.all end def new @article = Article.new end def edit @article = Article.find(params[:id]) end

/app/models/article.rb

class Article < ActiveRecord::Base attr_accessible :content, :tag, :titleend

現(xiàn)在想要在new.html.erb使用form_for創(chuàng)建一個表單

<%= form_for(@article) do |f| %><p class='field'> <%= f.label :title %><br /> <%= f.text_field :title %></p><% end %>

結(jié)果還只到這里測試的時候就出現(xiàn)了錯誤undefined method `articles_path’，麻煩大家?guī)兔纯词悄睦锍隽藛栴}。
