【问题描述】：
我正在尝试为一个表单创建一个“保存更改”按钮，该按钮将通过 ajax 将数据发送到控制器中的更新方法。目的是允许表单用户在不重新加载或重定向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'
需要明确的是，incorporation 是我们正在使用的控制器。下面是我添加的代码。
在我看来，我补充说：
<%= button_to "", update_incorporation_path(@incorporation), :remote => true, :method => :post %>
在我的路线中，我添加了：
resources :incorporations do
member do
post 'update'
end
end
更新方法如下：
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： edit.html.erb
<%= render 'form' %>
<br/>
<%= link_to "Back", root_path, class: "btn btn-default" %>
_form.html.erb（按钮在底部）
