Получить данные из набора запросов и передать в шаблон в django

Question

У меня есть модель, как показано ниже:

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)

и Вид, как показано ниже:

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

Я использую набор запросов в шаблоне, как показано ниже:

   <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>

знаю, у меня более одной коллекции, и я хочу разместить в коллекциях значение l oop, чтобы элементы каждой коллекции отображались в одном ряду. Но так как я новичок в django, я не знаю, как получить список коллекций и передать их в шаблон. пожалуйста, помогите мне.

Answer 1

Вы также можете перебирать объекты obj.collections. Как это

        {% 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 %}

Answer 3

В ключе object_list есть опечатка

context = {
    'objet_list':queryset,
}
