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 %}

Answer 1

您可以在查询集中使用。例如：annotate

from django.db.models import Avg

queryset = Film.objects.annotate(total_rating=Avg('reviews_rating'))

，然后在您的 html 文件中

{% for film in films %}

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

    {{ forloop.counter }}. {{ film.title }}

    {{ film.total_rating }}/5.0

{% endfor %}
