我有如下的HTML代码:



<html>
<head>
	<title>Booking Lah</title>
	<meta charset="utf-8">
	<meta name="viewport" content="width=device-width, initial-scale=1">
	<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
  <script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
  <script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>

  <style type="text/css">
    .card {
      height: 450px;
    }
    .card-image {
      max-height: 300px;
      max-width: 350px;
      width: auto;
      vertical-align: middle;
    }
    .image-display {
      height: 300px;
      width: auto;
    }
    .helper {
      display: inline-block;
      height: 100%;
      vertical-align: middle;
    }
    .image-caption {
      height: 100px;
    }
    .star {
      color: orange;
    }
  </style>
</head>

<body>
<nav class="navbar navbar-inverse">
  <div class="container-fluid">
    <div class="navbar-header">
      <a class="navbar-brand" href="home.php">Booking Lah</a>
    </div>
    <ul class="nav navbar-nav navbar-right">
      <li><a href="register.php"><span class="glyphicon glyphicon-user"></span> Sign Up</a></li>
      <li><a href="login.php"><span class="glyphicon glyphicon-log-in"></span> Login</a></li>
    </ul>
  </div>
</nav>

<div class="container">
<div class="row">

{{% for row in rows %}}
<div class="col-sm-4 card">
  <div class="image-display">
      <center>
          <span class="helper"></span><img src="{{row['imgurl']}}" class="card-image"><br>
      </center>
  </div>
      <div class="image-caption">
        <center>
          <h1><a href="#">{{row["name"]}}</a></h1>
          <h2>
            <span class="glyphicon glyphicon-star star"></span>
          </h2>
        </center>
      </div>
    </div>
{{% endfor %}}

</div>
</div>

</body>
</html>





我收到了这样的错误:


  jinja2.exceptions.TemplateSyntaxError
  TemplateSyntaxError:意外的'%'
  模板中的文件“ /home/m26415086/UHTOS/templates/home.html”,第55行
  {{%为行中的%%}}


我已经尽力了,但没有任何改变。

最佳答案

在模板中,您使用的是{{%%}}而不是{%%}

{%用于指令(循环,条件等),而{{用于替换。这是doc供进一步参考。
