Question

获取错误：ActionController::RoutingError (No route matches [POST] "/articles/new"):

从/articles/new页面执行POST时。

我在/app/views/articles/new.html.erb内的代码：

<%= form_for :article, url: articles_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>

/bin/rake routes输出：

              DELETE /articles/:id(.:format)      articles#destroy

Answer 1

只需将其更改为：

<%= form_for Article.new do |f| %>

了解如何在Ruby文档中使用resources with form_for。

Answer 2

在我尝试提出异常并且无法正常工作后，我开始怀疑。然后我意识到带有表单的页面从未在浏览器中刷新过。我只是按下并重新提交表格。愚蠢的错误。

总是很难（没有浏览器缓存）REFRESHES !!!

Rails helper form_for（）忽略url参数
