无法从数据库 Django 框架中获取图像

Question

I want to create a setting in admin panel which will help me to change the website logo from the admin panel. I create a model for database and it's working and uploading an image to the database + folder. but I cannot get this image to the Website template. when I'm viewing page source image SCR is empty.

my Model.py

class WebLogo(models.Model):
    Logotitle = models.CharField(max_length=50,unique=False)
    SiteLogo = models.ImageField(upload_to='webimages')

def __str__(self):
    return self.Logotitle

my Views.py

from .models import Post,WebLogo


def Display_WebLogo(request):
    # getting all the objects of hotel.
    WebsiteLogo = WebLogo.objects.all()
    return render((request, 'index.html',{'web_images' : WebsiteLogo}))

my project Urls.py

urlpatterns = [
    path('', views.PostList.as_view(), name='home'),
    path('<slug:slug>/', views.PostDetail.as_view(), name='post_detail'),
    ]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

my Html Code

  <a href="index.html"><img src="{{ WebLogo.SiteLogo.url }}" class="img-fluid" alt="logo">       
  </a>

my app url

from django.contrib import admin
from django.urls import path,include


urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('blog.urls')),
]

Answer 1

You should write the required information in the settings.py file.

Answer 2

In HTML Code, use 'web_images' not WebLogo like this

<a href="index.html"><img src="{{ web_images.0.SiteLogo.url }}" class="img-fluid" alt="logo">       
  </a>

It looks like {{ data.0 }}. See Variables and lookups .
