我在购物车页面上有一个表单来更新line_items。所以我正在更新的资源需要退出购物车控制器并进入line_items控制器...我正在使用以下表格......
<%= simple_form_for shifted_commerce_line_item_path(item),
:url => {controller: 'line_items', action: 'update'} do |f| %>
我没有路线匹配...
No route matches {:action=>"update", :controller=>"shifted_commerce/line_items"}
事情是......我在控制器中有动作......
我会发布我的路线。
shifted_commerce_line_items GET /shifted_commerce/line_items(.:format) shifted_commerce/line_items#index
POST /shifted_commerce/line_items(.:format) shifted_commerce/line_items#create
new_shifted_commerce_line_item GET /shifted_commerce/line_items/new(.:format) shifted_commerce/line_items#new
edit_shifted_commerce_line_item GET /shifted_commerce/line_items/:id/edit(.:format) shifted_commerce/line_items#edit
shifted_commerce_line_item GET /shifted_commerce/line_items/:id(.:format) shifted_commerce/line_items#show
PATCH /shifted_commerce/line_items/:id(.:format) shifted_commerce/line_items#update
PUT /shifted_commerce/line_items/:id(.:format) shifted_commerce/line_items#update
DELETE /shifted_commerce/line_items/:id(.:format) shifted_commerce/line_items#destroy
如何让此表单在我的控制器中点击更新操作？
我们不是看到上述路线吗？ PUT和PATCH都匹配/shifted_commerce/Line_items/:id ...我正在通过（项目）传递id ...
更新1 我还要补充一点，我在循环中运行此表单，因此可以编辑每个line_item。 @anything不是我想要传递给ID的路径...也是，我在推车行动中从推车控制器操作。不是line_item控制器，编辑操作。
更新2 如果我执行以下simple_form_for：
<%= simple_form_for shifted_commerce_line_item_path(item), :url => {controller: 'line_items', action: 'create'} do |f| %>
它成功地将我带入了line_items控制器的创建操作。但是如果我做的话
<%= simple_form_for shifted_commerce_line_item_path(item), :url => {controller: 'line_items', action: 'update'} do |f| %>
我收到路线错误。这是怎么回事？！ 为什么它适用于创建但不适用于更新？我的控制器中有更新操作...

更改此设置并尝试：
<%= simple_form_for item, url: shifted_commerce_line_items_path(item), method: :put do |f| %>
根据您路线
更新
抱歉，它必须是post，但不是put，如下所示：
<%= simple_form_for item, url: shifted_commerce_line_item_path(item), method: :post do |f| %>
答案 1 :(得分：0)
尝试使用<%= simple_form_for ([:shifted_commerce, item]) do |f| %> 或
<%= simple_form_for item, :url => shifted_commerce_line_item_path do |f| %>
