实际上我想显示一个 table，其中第一列应该显示 customers.Here 给出的星号是我的代码部分，我在其中遇到错误:-

 {% if restaurant.restaurantreview_set.all != 0 %}
  <table class="table table-striped table-bordered">
    <thead>
      <tr>
        <th>Rating</th>
        <th>Comment</th>
        <th>User</th>
        <th>Date</th>
      </tr>
    </thead>
    <tbody>
      {% for review in restaurant.restaurantreview_set.all %}
       <tr>
        <td>{% if review.rating == 1%}{% bootstrap_icon "star" %}
        {% elif review.rating == 2%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}
        {% elif review.rating == 3%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}
        {% elif review.rating == 4%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}
        {% elif review.rating == 5%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% endif %}</td>
        <td>{{ review.comment }}</td>
        <td>{{ review.user }}</td>
        <td>{{ review.date }}</td>
      </tr>
      {% endfor %}
    </tbody>
  </table>
{% else %}
  <p>Please post the review.</p>
{% endif %}

我尝试了很多事情，但无法succeed.Please提供帮助。提前致谢。

{% load bootstrap3 %}  -- add this line at the top of your layouts file


{% if restaurant.restaurantreview_set.all != 0 %}
  <table class="table table-striped table-bordered">
    <thead>
      <tr>
        <th>Rating</th>
        <th>Comment</th>
        <th>User</th>
        <th>Date</th>
      </tr>
    </thead>
    <tbody>
      {% for review in restaurant.restaurantreview_set.all %}
       <tr>
        <td>{% if review.rating == 1%}{% bootstrap_icon "star" %}
        {% elif review.rating == 2%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}
        {% elif review.rating == 3%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}
        {% elif review.rating == 4%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}
        {% elif review.rating == 5%}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% bootstrap_icon "star" %}{% endif %}</td>
        <td>{{ review.comment }}</td>
        <td>{{ review.user }}</td>
        <td>{{ review.date }}</td>
      </tr>
      {% endfor %}
    </tbody>
  </table>
{% else %}
  <p>Please post the review.</p>

无效的块标记：'bootstrap_icon'、应为 'elif'、'else' 或 'endif'
