django - 从查询集中检索数据并传递给 django 中的模板

Question

我有一个模型如下：

class Artwork(models.Model):
title              =     models.CharField(max_length=120)
collection         =     models.CharField(max_length=120,null=True)
slug               =     models.SlugField(blank=True, unique=True)
description        =     models.TextField()
price              =     models.DecimalField(decimal_places=2, max_digits=20, default=0)
image              =     models.ImageField(upload_to=upload_image_path, null=True, blank=True)
banner             =     models.ImageField(upload_to='artworks/banner')
video              =     models.FileField(upload_to='artworks/video',blank=True,null=True)
category           =     models.CharField(choices=CATEGORY_CHOICES, max_length=15)
views_count        =     models.IntegerField(default=150)
featured           =     models.BooleanField(default=False)
active             =     models.BooleanField(default=True)
created            =     models.DateTimeField(default=timezone.now)

和视图如下：

def artwork_list_view(request):
queryset    = Artwork.objects.all()
context = {
    'objet_list':queryset,
}
return render(request, "artworks/list.html", context)

我在模板中使用查询集如下：

   <div style='min-height:80px;'><p >First Collection</p></div>

    {% for obj in object_list  %}
        <div  class="workSeriesThumbnailStrip">
                {% if obj.image %}
            <a href="{{ obj.get_absolute_url }}"><img src="{{ obj.image.url }}" style="float:left;width:67px;height:87px;margin:10px;" ></a>
            {% endif %}

        </div>
    {% endfor %}
   </div>

知道我有多个集合，并且想在集合中放置一个 for 循环以在一行中显示每个集合的项目。但由于我是 django 的新手，我不知道如何检索集合列表并将它们传递给模板。请帮我。

Answer 1

您也可以遍历 obj.collections。像这样

        {% for obj in object_list %} <div class="workSeriesThumbnailStrip"> 
{% if obj.image %} 
<a href="{{ obj.get_absolute_url }}">
<img src="{{ obj.image.url }}" style="float:left;width:67px;height:87px;margin:10px;" ></a> 
{% endif %} 
</div>
    {%for collection in obj.collections%}
    <Div>{{colection}}<div/>
    {%end for%}
     {% endfor %}

object_list键中有错字

context = {
    'objet_list':queryset,
}
