你知道吗视图.py你知道吗

from django.shortcuts import render
from .forms import ContactForm
from django.utils import timezone
from .models import Project
# Create your views here.


def index(request):
    form_class = ContactForm
    projects = Project.objects.filter(published_date__lte=timezone.now()).order_by('-published_date')
    return render(request, 'ports/index.html', {'form': form_class, 'projects': projects})

Answer 1

看看你的img标签。在src属性中，您使用的是{{ projects.photo.url }}。因此，不能从queryset获取图像，只能从Project模型的对象获取图像。使用{{ project.photo.url }}
