NoReverseMatch at / polls / Reverse for 'vote' with arguments '(' ',)' not found . 1种模式尝试过：['polls/(?P<question_id>[0-9]+)/vote/$']

NoReverseMatch at / polls /

使用参数'（''，）找不到“投票” . 尝试过1种模式：['民意调查/（？P [0-9]）/投票/ $']

index.html的：

{% if latest_question_list %}
    <ul>
    {% for question in latest_question_list %}
    <!-- # the 'name' value as called by the  url  template tag -->
        <li><a href="{% url 'polls:detail' question.id %}">{{ question.question_text }}</a></li>
<!-- or:
    <li><a href=" url 'detail' question.id "> question.question_text </a></li>
    How does one make it so that Django knows which app view to create for a url when using the  url  template tag?
    So we use polls:detail
 -->
    {% endfor %}
    </ul>
    {% else %}
        <p>No polls are available.</p>
    {% endif %}

    <h1>{{ question.question_text }}</h1>

    {% if error_message %}<p><strong>{{ error_message }}</strong></p>{% endif %}

    <form action="{% url 'polls:vote' question.id %}" method="post">
    {% csrf_token %}
    {% for choice in question.choice_set.all %}
        <input type="radio" name="choice" id="choice{{ forloop.counter }}" value="{{ choice.id }}">
        <label for="choice{{ forloop.counter }}">{{ choice.choice_text }}</label><br>
    {% endfor %}
    <input type="submit" value="Vote">
    </form>

下面是控制台错误 . stackoverflow中的其他相关问题的答案如下：not question_id！这是个问题 .
