比较Django中的appengine数据库值

Hi i have an appengine application with the following db.Model:

您好，我有一个appengine应用程序，它具有以下db.Model:

class Cinema(db.Model):
    name = db.StringProperty()
    address = db.StringProperty()
    distance = db.IntegerProperty()
    user = db.ReferenceProperty(RunningUser)

When I fill my template everythings works fine:

当我填满模板时，一切都很顺利:

            {% for cinema in cinemas %}
                <tr>
                    <td><img src="/images/cinema.png"></td>
                    <td>
                        <a href="...">
                            <h2>{{cinema.name}}</h2>
                        </a>
                        {{cinema.address}}
                    </td>
                    <td>
                        {% if cinema.distance > 10000 %}
                            <p>red</p>
                        {% endif %}
                    </td>
                </tr>
            {% endfor %}

Except the if statement. Python raises a TemplateSyntaxError: 'if' statement improperly formatted exception. According to Django it should be fine. So what is wrong with these three lines?

除了if语句。Python会引发一个TemplateSyntaxError: 'if'语句格式不正确的异常。根据Django的说法，应该没问题。这三行有什么问题呢?

{% if cinema.distance > 10000 %}
    <p>red</p>
{% endif %}

try this:

试试这个:

{% if cinema.distance > 10000 %}
    <p>red</p>
{% endif %}
