我正在研究 rubyonrails.org 的“博客教程”,当我尝试提交“帖子”时出现此错误:路由错误 -- 没有路由匹配 [POST] "/posts/new"
我将教程中的代码复制并粘贴到我的代码中。这应该返回带有帖子文本和标题的哈希,但我得到了上述错误。
这是我的看法:
<%= form_for :post, url: posts_path do |f| %>
<p>
<%= f.label :title %><br>
<%= f.text_field :title %>
</p>
<p>
<%= f.label :text %><br>
<%= f.text_area :text %>
</p>
<p>
<%= f.submit %>
</p>
<% end %>
这是我的控制器:
class PostsController < ApplicationController
def new
end
def create
render text: params[:post].inspect
end
end
这是我的路线.rb:
Blog::Application.routes.draw do
resources :posts
end
rake routes 给出了这个:
posts GET /posts(.:format) posts#index
POST /posts(.:format) posts#create
new_post GET /posts/new(.:format) posts#new
edit_post GET /posts/:id/edit(.:format) posts#edit
post GET /posts/:id(.:format) posts#show
PUT /posts/:id(.:format) posts#update
DELETE /posts/:id(.:format) posts#destroy
这是 rails 的窗口生成的内容:

在我尝试逐字逐句的其他教程中,我也遇到了同样的错误。我错过了什么?
谢谢。
