預編譯時找不到JavaScript資產中的路由助手方法

Question

我正在使用依賴於路線助手方法的JavaScript資產進行Rails項目。

在我的.js.erb ，我開始於：

 <% environment.context_class.instance_eval { include Rails.application.routes.url_helpers } %>

然后編寫javascript本身：

  jQuery("#search_keyword")
  .bind("keydown", function(event) {
        if(event.keyCode === jQuery.ui.keyCode.TAB &&
           jQuery(this).data("ui-autocomplete").menu.active) {
                   event.preventDefault();
            }
  })
  .autocomplete({
        source: function (request, response) {
                jQuery.getJSON ( '<%= search_complete_belongings_path(:json) %>', {
                             term: extractLast (request.term)
                          }, response);
        },
        search: function() {
                var term = extractLast (this.value);
                if (term.length < 2) {
                   return false;
                }
        },
        focus: function(event, ui) {
            return false;
        },
        select: function(event, ui) {
            var terms = split (this.value);
            terms.pop(),
            terms.push(ui.item.belonging.name);
            this.value=terms;
            return false;
        }
    })
    .data( "ui-autocomplete" )._renderItem = function( ul, item ) {
        return $( "<li>" )
            .data( "item.autocomplete", item.belonging )
            .append( "<a>" + item.belonging.name + "</a>" )
            .appendTo( ul );
    };

該函數依賴jquery-ui來實現自動完成功能，並對以下路由進行ajax調用：

<%= search_complete_belongings_path(:json) %>

該代碼在dev中工作正常，但是一旦執行assets:precompile ，就會出現以下錯誤：

   NoMethodError: undefined method `search_complete_belongings_path' for #<#<Class:0x0000000279df18>:0x00000003813730>

不知道它可以從哪里來？

謝謝！

您不能使用輔助程序，例如app/assets中的search_complete_belongings_path ，因為它們是動態的並且僅在rails視圖中工作。 另一方面，您的資產是靜態的，並且一旦進行了預編譯
