Django评级之星显示

Question

我是django的新手，但遇到了问题。例如，电影的等级为4，通常有5颗星，例如，我要显示4个阴影星和1个不阴影星。结果：不显示星星

Django模板

 <span class="rating">
                             {% for rating in movie.rating_set.all %}
                                {% for k, v in star_form.fields.star.choices %}
                                    {% if rating.star > 0 %}
                                    <input id="rating{{ rating.star }}" type="radio" name="star"
                                           value="{{ k }}">
                                    <label class="changed" for="rating{{ rating.star }}">{{ k }}</label>
                                    {% elif rating.star == 0 %}
                    <input id="rating{{ v }}" type="radio" name="star"
                                           value="{{ k }}">
                                    <label  for="rating{{ v }}">{{ k }}</label>
                                     {% endif %}
                                {% endfor %}
                            </span>

CSS

    .rating > label {
        position: relative;
        display: block;
        float: right;
