python - Django，在从管理面板上传的模板中显示图像

Question

我正在学习在 Django 中上传和显示图像，但我遇到了一个 block ，我无法弄清楚如何从数据库中调用图像位置，然后将其显示在模板中，我已经上传了来自管理面板的图像并希望将其显示在模板中...

models.py从 django.db 导入模型从导入时间开始

class Couple(models.Model):
    image_bride = models.ImageField(upload_to='vivaah/static/media')
    image_groom = models.ImageField(upload_to='vivaah/static/media')

vivaah/views.py

def index(request, bride_first_name, groom_first_name):
    obj = Couple.objects.get(bride_first_name__iexact=bride_first_name)
    image_bride = obj.image_bride
    image_groom = obj.image_groom
    context = {'image_bride':image_bride, 'image_groom':image_groom}
    return render(request, 'vivah/index.html', context)

templates/index.html

<img class="profile_pic" src="{{ image_bride.url }}"/>

vivaah/urls.py

from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.conf import settings
from . import views
import os

urlpatterns = [
    url(r'^(?P<bride_first_name>[a-zA-Z]+)weds(?P<groom_first_name>[a-zA-Z]+)/$', views.index, name='index'),
]

urls.py

from django.conf.urls import include, url
from django.contrib import admin


from django.conf.urls import patterns, include, url
from django.conf.urls.static import static
from django.conf import settings
import os


urlpatterns = [
    url(r'^vivah/', include('vivaah.urls')),
    url(r'^admin/', include(admin.site.urls)),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

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

它只显示图像的边框，而不显示实际图像

在您的templates/index.html中，您要求提供情侣对象的网址 <img class="profile_pic" src="{{ couple.image_bride.url }}"/>但夫妇没有传递到您的模板。

更改此行context = {'image_bride':image_bride, 'image_groom':image_groom}
对此context = {'couple': obj}
