如何在django3模板上显示上传的文件或图片

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    # 其他URL配置
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

from django.db import models

class MyModel(models.Model):
    image = models.ImageField(upload_to='images/')

python manage.py makemigrations
python manage.py migrate

from django.shortcuts import render
from .forms import MyForm

def upload_file(request):
    if request.method == 'POST':
        form = MyForm(request.POST, request.FILES)
        if form.is_valid():
            instance = MyModel(image=request.FILES['image'])
            instance.save()
            # 其他处理逻辑
    else:
        form = MyForm()
    return render(request, 'upload.html', {'form': form})

{% for instance in instances %}
    <img src="{{ instance.image.url }}" alt="Image">
{% endfor %}
