Ajax 表单提交无效
Ajax form submition not working
我正在尝试为表单创建一个 "Save Changes" 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 运行 遇到了一些问题；我收到以下错误
undefined method `update_incorporation_path'
明确地说，incorporation 是我们正在使用的控制器。下面是我为完成此操作而添加的代码。
以我的观点，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

我想我一定是忘记了什么。非常感谢任何想法。
update 方法的路由是在您编写 resources :incorporations 时默认添加的，因此请将您的路由更改为
resources :incorporations
而你的路径应该是incorporation_path，另外button_to中的方法默认是post，不用写，
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，它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 %>
希望对您有所帮助！
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。您不需要手动声明它。
您可以从控制台验证路由。
rake routes | grep 'incorporations'
您将得到如下输出：
从这里您可以构建更新操作的路径。
希望对您有所帮助:)
