Javascript 未定义的方法'item_path'；在使用ajax时

我试图更新我的create

item

操作以使用Ajax，但是我得到了一个

undefined method

item\u path`错误，这是我以前在以常规html格式响应时没有得到的。该项已创建并保存，但ajax似乎无法正常工作

user_items GET    /users/:user_id/items(.:format)          items#index
                     POST   /users/:user_id/items(.:format)          items#create
       new_user_item GET    /users/:user_id/items/new(.:format)      items#new
      edit_user_item GET    /users/:user_id/items/:id/edit(.:format) items#edit
           user_item GET    /users/:user_id/items/:id(.:format)      items#show
                     PATCH  /users/:user_id/items/:id(.:format)      items#update
                     PUT    /users/:user_id/items/:id(.:format)      items#update
                     DELETE /users/:user_id/items/:id(.:format)      items#destroy

这是我的"部分":

   <%= form_for [@user, item], remote: true do |f|%>
      <div class="form-group">
        <%= f.label :name, class: 'sr-only' %>
        <%= f.text_field :name , class: 'form-control', placeholder: "Enter a new item " %>
      </div>
      <%= f.submit "Submit Item", class: 'btn btn-primary pull-right' %>
    <% end %>

user_items GET    /users/:user_id/items(.:format)          items#index
                     POST   /users/:user_id/items(.:format)          items#create
       new_user_item GET    /users/:user_id/items/new(.:format)      items#new
      edit_user_item GET    /users/:user_id/items/:id/edit(.:format) items#edit
           user_item GET    /users/:user_id/items/:id(.:format)      items#show
                     PATCH  /users/:user_id/items/:id(.:format)      items#update
                     PUT    /users/:user_id/items/:id(.:format)      items#update
                     DELETE /users/:user_id/items/:id(.:format)      items#destroy

create.js.erb：

$('.js-items').prepend("<%= escape_javascript(render(@item)) %>");
   $('.new-item').html("<%= escape_javascript(render partial: 'items/form', locals: {user: @user , item: @item }) %>");

user_items GET    /users/:user_id/items(.:format)          items#index
                     POST   /users/:user_id/items(.:format)          items#create
       new_user_item GET    /users/:user_id/items/new(.:format)      items#new
      edit_user_item GET    /users/:user_id/items/:id/edit(.:format) items#edit
           user_item GET    /users/:user_id/items/:id(.:format)      items#show
                     PATCH  /users/:user_id/items/:id(.:format)      items#update
                     PUT    /users/:user_id/items/:id(.:format)      items#update
                     DELETE /users/:user_id/items/:id(.:format)      items#destroy

我进入rails时出错：

user_items GET    /users/:user_id/items(.:format)          items#index
                     POST   /users/:user_id/items(.:format)          items#create

做类似的事情

user_items GET    /users/:user_id/items(.:format)          items#index
                     POST   /users/:user_id/items(.:format)          items#create

      edit_user_item GET    /users/:user_id/items/:id/edit(.:format) items#edit
           user_item GET    /users/:user_id/items/:id(.:format)      items#show
                     PATCH  /users/:user_id/items/:id(.:format)      items#update
                     PUT    /users/:user_id/items/:id(.:format)      items#update
                     DELETE /users/:user_id/items/:id(.:format)      items#destroy

<%= form_for [@user, item], user_items, remote: true do |f|%>

在终端中查看您的路径。

您的部分中的路径设置有问题。@mohammadshahahadathossain我认为这是因为rails的错误清楚地说明了这一点，但idk我无法修复它。我尝试了它，但它不起作用这里是我的项目路径

POST/users/：user\u id/items（：format）items#create new_user_item GET/users/：user_id/items/new（：format）items#new

我得到一个完全不同的错误
