Question

我在Django中显示用户图像时遇到了麻烦，似乎主要是工作。当用户提交图片时，它已成功存储它在右侧文件夹中。但是在我保存后我无法显示图片。

Views.py：

def upload_pic(request):
    user = User.objects.get(id=request.user.id)
    form = ImageUploadForm(request.POST, request.FILES)
    if request.method == 'POST':
        if form.is_valid():
            form.save()

    return render(request, 'tracker/upload_pic.html')


def album(request):
    user = User.objects.get(id=request.user.id)
    if request.method == "POST":
        user.extendedprofile.img = request.FILES['uploaded_image']
        user.extendedprofile.save()
        #ExtendedProfile.objects.filter(pk=request.user.id).update(extendedprofile__img=request.FILES['uploaded_image'])

    return render(request, 'tracker/album.html', {"user": user})

settings.py（相关部分）

STATIC_URL = '/static/'
STATIC_ROOT = '/viraone/tracker/static'

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

models.py

def user_directory_path(instance, filename):
    return 'user_images/user_{0}/{1}'.format(instance.user.id, filename)

class ExtendedProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    amount_spent = models.DecimalField(max_digits=6, decimal_places=2, default=0, blank=True)
    img = models.ImageField(upload_to=user_directory_path)

forms.py

class ImageUploadForm(forms.ModelForm):
    #model to store the information about the pictures
    class Meta:
        model = ExtendedProfile
        exclude = ()

urls.py

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

urlpatterns = [url(r'^profile', views.profile, name='profile'),
url(r'^login', views.login, name='login'),
url(r'^export_info', views.export_info, name='export_info'),
url(r'^product_page', views.product_page, name='product_page'),
url(r'^(?P<object_id>[0-9]+)/$', views.product_details, name='product_details'),
url(r'^upload_pic', views.upload_pic, name='upload_pic'),
url(r'^album', views.album, name='album'),
]

if settings.DEBUG:
    urlpatterns + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

模板：

{% load staticfiles %}

<!DOCTYPE html>
<html>

<p> {{ user.extendedprofile.img }} </p>
<img src="{{ user.extendedprofile.img.url }}"
</html>

我认为这是urls.py的问题，在调试菜单中，它显示正确文件路径的404错误，但图像没有出现。

在urls.py

中更改此内容

if settings.DEBUG:
    urlpatterns + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

到

if settings.DEBUG:
    urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

并在模板中

<img src="{{ user.extendedprofile.img.url }}">

无法使用django从本地服务器检索用户图像
