当我尝试访问包含用于创建帖子的表单的页面时,我在Rails应用程序中收到以下错误。我正在尝试在他的示例应用程序中实现类似于Michael Hartl的Micropost功能的功能:
NoMethodError in Home#index
undefined method `posts_path' for #<#<Class:0xb5c70744>:0xb60013b8>
这是索引视图页面,其中包含插入表单的代码:
<%= render 'shared/post_form' if user_signed_in? %>
_post_form.html.erb:
<%= form_for(@post) do |f| %>
<%= render 'shared/error_messages', object: f.object %>
<div class="field">
<%= f.text_area :content, placeholder: "Provide your network with a status update..." %>
</div>
<%= f.submit "Post", class: "btn btn-large btn-primary" %>
<% end %>
这是家庭控制器:
class HomeController < ApplicationController
before_filter :authenticate_user!
def index
#render :text => "Welcome #{current_user.email}!"
@users = User.all
@post = current_user.posts.build if signed_in?
end
end
我可以在查看代码时使用一些帮助。我正盯着它,我需要别人为我审查。我是Rails的新手,如果我没有提供必要的信息,请原谅我。
其他信息:我正在使用Devise gem来处理用户身份验证。
谢谢!
编辑:我添加了错误的控制器。编辑2:
Routes.rb文件:
AppName::Application.routes.draw do
#get "users/index"
#get "users/show"
authenticated :user do
root :to => 'home#index'
end
root :to => "home#index"
devise_for :users
resources :users do
member do
get :following, :followers, :posts
end
end
resources :works
resources :relationships, only: [:create, :destroy]
end

您需要在resources :posts
文件中添加routes.rb
,以便Rails自动为您创建posts_path
帮助程序。
添加resources :posts
将生成适当的RESTful路由,供您创建,删除,更新和获取posts
。请查看Ruby on Rails指南以获取路由,特别是路由和RESTful路由上的this section here。
