Question

我一直为＃＆lt;＃：0x0000376c505098＆gt;

获取未定义的局部变量或方法`orders_download_template_path'

使用以下代码。我也尝试过download_template_path和@orders_download_template_path（最后一个不会抛出错误，但也没有做任何事情）。

routes.rb中：

  resources :orders do   
    collection do
      post :import
      get  :upload_page, as: 'upload_page'
      get  :search, as: 'search'
      get  :csv_report, as: 'csv_report'
      get  :overdue_csv_report, as: 'overdue_csv_report'
      get  :download_template, as: 'download_template'
    end
  end

orders_controller.rb：

  def download_template
    send_file Rails.root.join('public/upload_template.csv'),
    type: 'application/csv',
    x_senfile: true
  end

视图：

<%= link_to "Blank Upload Template", orders_download_template_path %>

文件已放置在/ public

根据Rails路由指南，您会遇到语法错误。

这应该解决它

<?php
$db = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);

if(isset($_POST['submit'])){
    $count=0;
    $url_text=$_POST['content'];
    $urls=explode(",",$url_text);
    if(count($urls)>20){
        echo "Url Should not exceed 20";           
    }else{
        for($j=0;$j<count($urls);$j++){
            if($urls[$j]!=''){
                $url=$urls[$j];

                    $content_input=explode(":",$new_input[0]);
                    $content[]=trim($content_input[1]);

如果您在控制台上运行rake routes，则应该看到以下行（以及其他行）：

 download_template_orders GET    /orders/download_template(.:format)   orders#do

如您所见，如果您在COLLECTION上设置此路线，则路径生成将为download_template_orders_path。

如果您在会员上设置它，您会看到：

 download_template_order GET    /orders/:id/download_template(.:format)  orders#

回答你的问题，正确的路径是download_template_orders_path
