以 html 格式显示评级

Question

我正在django中做一个项目，在那里我根据评论中给出的评级创建了一个toplist。有没有办法获得html中显示的电影的评级？

与 models.py 相比

class Film(models.Model):

    title = models.CharField(max_length=100)

    title_short = models.CharField(max_length=17, default=None, null=True)

    plot = models.TextField()

    poster = models.ImageField(default="default.png", upload_to="posters")

    release_date = models.DateField(blank=True, null=True)

    date_posted = models.DateTimeField(default=timezone.now)

class Review(models.Model):

    writer = models.ForeignKey(User, on_delete=models.CASCADE)

    reviewed_film = models.ForeignKey(Film, related_name='reviews', on_delete=models.CASCADE)

    title = models.CharField(max_length=100)

    content = models.TextField()

    rating = models.IntegerField(

        default=1, validators=[MinValueValidator(1), MaxValueValidator(5)]

    )

    def __str__(self):  # pragma: no cover

        return f"{self.reviewed_film.title} reviewed by {self.writer.username}"

从排行榜.html

{% extends "board/base.html" %}

{% block content %}

<h1>Toplist</h1>

  {% for film in films %}

    <div class="col s12 m7">

      <h2 class="header"></h2>

      <div class="card horizontal">

        <div class="card-image">

          <img src="/media/{{film.poster}}">

        </div>

        <div class="card-stacked">

          <div class="card-content">

            <h5>{{forloop.counter}}. {{film.title}}</h5>

            <p>{{}}/5.0</p>

          </div>

          <div class="card-action">

            <a href="#">Read more</a>

          </div>

        </div>

      </div>

    </div>

  {% endfor %}

{% endblock content %}

您可以在查询集中使用。例如：annotatefrom django.db.models import Avgqueryset = Film.objects.annotate(total_rating=Avg('reviews_rating'))，然后在您的 html 文件中{% for film in films %}&nbsp; &nbsp; <img src="/media/{{ film.poster }}">&nbsp; &nbsp; {{ forloop.counter }}. {{ film.title }}&nbsp; &nbsp; {{ film.total_rating }}/5.0{% endfor %}本文档包含更多详细信息。
