Django：如何在图像模型中显示所有图像

Question

我正在尝试显示与当前所选用户相关联的所有图片

这是基于这个已解决的问题：django upload to image model with foreign key to user

Model.py

class Images(models.Model):
    image = models.ImageField(upload_to='profile_image', null=True, default='profile_image/none/no-img.png')
    user = models.ForeignKey(User, on_delete=models.CASCADE)

Views.py

@login_required
def index_account(request):
    args = {'user': request.user }
    return render(request, 've/cp/index_account.html', args)

模板＆gt; index_account.html

    <p><a href="{% url 've:edit_images' %}">Edit your images</a></p>
    # test to see if it worked w/o if
    {{ user.images.image}}

    # ideal solution
    {% if user.images.images %}
        {% for img in user.images %}
        <img src="{{ user.images.image.url }}"><br>
        {% endfor %}
    {% else %}
    <p>No images</p>

    {% endif %}

    <br>

您提供的代码无法满足您的需求。所以这里有一个可能的例子：

示例

views.py

from app_name.models import Images 
@login_required
def index_account(request):
    images = Images.objects.filter(user=request.user)
    return render(request, 've/cp/index_account.html', {"images": images})

index_account.html

<p><a href="{% url 've:edit_images' %}">Edit your images</a></p>

# ideal solution
{% if images %}
    {% for img in images %}
    <img src="{{ img.url }}"><br>
    {% endfor %}
{% else %}
<p>No images</p>

{% endif %}

<br>

希望这有帮助！
