Question

我正在研究需要登录的flask-sqlalchemy webapp。仅当用户登录时，才应在页面上显示注销按钮。所以这些页面扩展了layout.html文件，如下所示：

<!DOCTYPE html>
<html lang="en">



<head>

    <meta charset="utf-8">
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta name="viewport" content="width=device-width, initial-scale=1">
    <meta name="description" content="">
    <meta name="author" content="">

    <title>Login</title>

    <link href="{{ url_for('static', filename='css/bootstrap.min.css') }}" rel="stylesheet">
    {% block head %} {% endblock %} 

</head>

<body>
{% block body %}
<style type="text/css">
  #footer {
    position : absolute;
    bottom : 0;
  }
</style>
{ % if session['logged_in'] %}

<div id="footer" style="width:300px;height:100px"><a href="   {{url_for('logout')}}" style="width:100%;background:#f1f1f1;">Logout</a></div>

{% endif %}

{% endblock %}


    <script src="{{ url_for('static', filename='js/jquery.js') }}"></script>
    <script src="{{ url_for('static', filename='js/bootstrap.min.js') }}"></script>

</body>

</html>

我得到的错误是：

TemplateSyntaxError：遇到未知标签'endif'。金贾是寻找以下标签：'endblock'。

需要关闭的最里面的块是'block'。

虽然已指定了endblock和if标签请帮我解决这个问题

尝试删除{和％in

之间的空格

function createOrderStatuses(){
  var access_token = BCAPI.Helper.Site.getAccessToken();
  var request = $.ajax({
      url: "/webresources/api/v3/sites/current/orderstatuses",
      type: "GET",
      connection: "keep-alive",    
      contentType: "application/json",
      headers: _authorization
  });
  request.done(function (msg) {
      console.log(msg);
      //var orderStatusesArray = msg[];
      for (var i = 0; i < msg.items.length; i++){
           var statuses = msg.items[i];
           var statusTemplate = '<div class="large-12 columns margin-distributed statusClass" id="'+ statuses.id +'"><h4 class="lato-bold">' + statuses.label  + '</h4></div>';

      if (statuses.label !== "EXCHANGE FEE PAID"){
        $("#ordersContainer").append(statusTemplate);
      }else{
        //$(".orderStatuses").append('<option value="'+ statuses.id +'">' + statuses.label  + '</option>');
      }
    }//looping and displaying statuses

   getOrders();

  });//request END


  function getOrders(){

     var access_token = BCAPI.Helper.Site.getAccessToken();
     var request = $.ajax({
         url: "/webresources/api/v3/sites/current/orders",
         type: "GET",
         connection: "keep-alive",    
         contentType: "application/json",
         headers: _authorization
     });
     request.done(function (msg) {
         console.log(msg);
         var containerID = $('.statusClass').each(function(){ $(this).attr('id'); });

         for (var i = 0; i < msg.items.length; i++){
           var orders = msg.items[i];

           var orderTemplate = '<div class="large-12 columns margin-distributed '+ orders.statusTypeId +'"><h5>' + orders.name  + '</h5></div>';
           var orderTemplateClass = orderTemplate.find('div[class*="'+orders.statusTypeId+'"]');

           if  ( orderTemplateClass === containerID ){          
                       $(containerID).append(orderTemplate); 
               }// end IF       

    }//looping orders

     }); 
  }//GET ORDERS END


 }
 createOrderStatuses();

这样就变成了

{ % if session['logged_in'] %}

flask：虽然指定了标签，但遇到了未知标签endif
