如何在 django 中显示编辑后的个人资料图片

Question

我可以上传个人资料图片，但无法编辑它

我用图像浏览选项填充了表单，但是当我单击保存时，它实际上并没有在模板中更新。 但它在管理中工作正常

views.py

def create_form(request):
        form = AlbumForm(request.POST or None, request.FILES or None)
        if form.is_valid():
            album = form.save(commit=False)
            album.user = request.user
            album.image= request.FILES['image']
            album.save()
            return render(request, 'about.html', {'album': album})
        context = {
            "form": form,
        }
        return render(request, 'create_form.html', context)
def profile_edit(request):
    if request.method == 'POST':
        form = AlbumForm(request.POST, instance=request.user.album)
        if form.is_valid():
            album = form.save(commit=False)
            album.user = request.user
            form.save()
            return redirect(reverse('about'))
    else:
        form = AlbumForm(instance=request.user.album)
        args = {'form': form}
        return render(request, 'profile_edit.html', args)

models.py

class Album(models.Model):
    user = models.OneToOneField(User)
    image = models.FileField()

forms.py

class AlbumForm(forms.ModelForm):
    class Meta:
        model = Album
        fields = ['image']

profile_edit.html

{%  extends 'base.html' %}
{%  block   content %}
<form action="{% url 'profile_edit' %}" method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit" class="save btn btn-default">save</button>
</form>
<div>
      <img src="{{ user.album.image.url }}" class="img-responsive">
</div>
{%  endblock    %}

Answer 1

试试这个

AlbumForm(request.POST, request.FILES, instance=request.user.album)

Answer 2

您需要

在配置文件编辑视图中向AlbumForm添加request.FILES。

Answer 3

如果上传文件，则必须使用request.Files阅读更多信息 此链接
