使用 bootstrap4 輪播的 django 網站中的滑塊

Question

我想在我的 django 網站中創建一個輪播滑塊，在那里我可以輕松地從我的管理面板添加/刪除圖像。

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
      <li data-target="#carouselExampleIndicators" data-slide-to="0" class="active"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="1"></li>
      <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner">
        {% for obj in projects %}
            {% if forloop.first %}
                <div class="carousel-item active  ">
            {% else %}
                <div class="carousel-item  ">
            {% endif %}
            <img class="d-block w-100 h-50" class="h-50 d-inline-block" src="{{ obj.thumbnail.url}}" alt="{{obj.title}}">
            </div>

        {% endfor %}
    </div>

Answer 1

你的html模板是正常的。 您需要像這樣創建模型：

class Carousel(models.Model):
    image = models.ImageField()

在您的 admin.py 中：

...
admin.site.register(Carousel)

鑒於：

...
projects = Carousel.objects.all()
return render(request, 'template.html', {'projects': projects})

<div id="carouselExampleIndicators" class="carousel slide" data-ride="carousel">
    <ol class="carousel-indicators">
        {% for obj in sliderview %}
            {% if forloop.first %}
                <li data-target="#carouselExampleIndicators" data-slide-to="{{forloop.counter0}}" class="active"></li>
            {% else %}
                <li data-target="#carouselExampleIndicators" data-slide-to="{{forloop.counter0}}"></li>

            {% endif %}
        {% endfor %}
      <li data-target="#carouselExampleIndicators" data-slide-to="2"></li>
    </ol>
    <div class="carousel-inner">
        {% for obj in sliderview %}
            {% if forloop.first %}
                <div class="carousel-item active  ">
            {% else %}
                <div class="carousel-item  ">
            {% endif %}
            <img class="d-block w-100 h-50" class="h-50 d-inline-block" src="{{ obj.thumbnail.url}}" alt="{{obj.title}}">
            </div>

        {% endfor %}
    </div>

    <a class="carousel-control-prev" href="#carouselExampleIndicators" role="button" data-slide="prev">
      <span class="carousel-control-prev-icon" aria-hidden="true"></span>
      <span class="sr-only">Previous</span>
    </a>
    <a class="carousel-control-next" href="#carouselExampleIndicators" role="button" data-slide="next">
      <span class="carousel-control-next-icon" aria-hidden="true"></span>
      <span class="sr-only">Next</span>
    </a>
    </div>
</div>
