Question

我试图创建一个＆＃34; Save Changes＆＃34;表单的按钮，用于通过ajax将数据发送到控制器中的update方法。目的是允许表单用户在没有重新加载或重定向的表单的情况下保存他们的工作。但是，我遇到了一些问题;我收到以下错误

未定义的方法`update_incorporation_path＆＃39;

要明确，incorporation是我们正在使用的控制器。以下是我为实现此目的而添加的代码。

我认为，我补充道：

<%= button_to "", update_incorporation_path(@incorporation), :remote => true, :method => :post %>

对于我的路线，我补充道：

resources :incorporations do
  member do
    post 'update'
  end
end

更新方法如下所示：

  def update
    if @incorporation.update(incorporation_params)
      if admin_signed_in?
    @incorporations = Incorporation.all.order("created_at DESC")
      else
    @incorporations = current_user.incorporations("created_at DESC")
      end
      render action: "index"
    else
      render 'edit'
    end
  end

完整视图如下： 的 edit.html.erb

<%= render 'form' %>

<br/>
<%= link_to "Back", root_path, class: "btn btn-default" %>

_form.html.erb （按钮位于底部）

    <%= button_to "Update", incorporation_path(@incorporation), method: :post, remote: true %>
  <% end =%>
</div>

我想我必须忘记一些事情。任何想法都非常感激。

Answer 1

默认情况下，在您编写update时添加了resources :incorporations方法的路由，因此请将路由更改为

resources :incorporations

您的路径应该是incorporation_path，button_to中的方法默认为post，您不需要编写它，

将您的button_to更改为

<%= button_to "Update", incorporation_path(@incorporation), :remote => true %>

但是，如果您要提交表单，则应该有一个提交按钮而不是button_to，您的表单应该如下所示

<%= form_for @incorporation, remote: true do |f| %>
  # form content
  <%= f.submit "Submit" %>
<% end %>

希望这有帮助！

Answer 2

而不是：

<%= button_to "", update_incorporation_path(@incorporation), 
   :remote => true, :method => :post %>

尝试：

<%= button_to "Update", incorporation_path(@incorporation), 
   method: :post, remote: true %>

在你的路线中：

resources :incorporations

资源附带默认操作索引，新建，创建，编辑，更新，销毁。您无需手动声明它。

您可以从控制台验证路线。

 rake routes | grep 'incorporations'

您将获得如下输出： enter image description here 从这里，您可以构建更新操作的路径。希望它有所帮助：）
