用户可以通过models.py上传zip文件，但我无法解压该文件以遍历图像并在模板中显示它们

Models.py views.py Post-create和index-view有效/或至少有效，直到我从上传单个图像改为上传zip文件并尝试迭代

class IndexView(generic.ListView):
    template_name='photos/post.html'
    def get_queryset(self):
        return Post.objects.filter(user=self.request.user)

def DetailView(request,pk=""):
    model = Post
    z = zipfile.ZipFile()   ### I am unsure of what goes here!!
    context = {
        "images": z,
        }
    template_name = 'photos/detail.html'
    return render(request,template_name,context)

class PostCreate(generic.CreateView):
    form = PostForm()
    model = Post
    fields = ['title','body','album_image']
    if form.is_valid():
        instance = form.save(commit=False)
        username = form.cleaned_data['username']
        album_image = form.cleaned_data['album_image']
        instance.save()
        context = {
        "form": form,
        }

我会小心处理zip内容，可能会在这里检查循环中的文件名/类型，但下面类似的内容可能会起作用（未经测试）。基本上提取内容（假设不在zip的子文件夹中），然后Base64对其进行编码，并在src中使用该编码版本来指定数据类型

# views.py  
import base64
import zipfile

def DetailView(request,pk=""):
    model = Post
    # z = zipfile.ZipFile()   ### I am unsure of what goes here!!
    mydoc = 'path_to_zip_file_here'
    # probably should do some logic on the name and file type
    # or be very aware of what is in the zip file
    with zipfile.ZipFile(mydoc, 'r') as z:
        for f in z.namelist():
            images.update({f: base64.b64encode(z.read(f)),})

    context = {
        "images": images,
        }
    template_name = 'photos/detail.html'
    return render(request,template_name,context)

和detail.html：

{% for name, image in images.items %}
<img src ="data:image/jpeg;base64,{{ image }}" style="width:304px;height:228px;">
{% endfor%}

{%表示名称，图像中的图像。项目%}
{%endfor%}

对不起，我是Django的新手，您如何获取zip文件的路径？它是否只是settings.py w.r.t MEDIA_URL中创建的路径？谢谢你的帮助！是的，可能。你如何处理最初的上传？你是如何展示单个图像的？这将是我怀疑的同一条路径。与上面相同的IndexView类。然后上面的def DetailView最初是类DetailView（generic.DetailView），它只包含模型和模板名称，detail.html是相同的，没有for循环，而是有，为什么在这里对上传的文件进行base64编码？使用django one将上传文件的路径保存到数据库中，而不是保存文件本身（这正是应该的方式）@LukeCollins您是对的，只需使用post.album_图像作为zipfile路径。
