Python Django HTML变量中的Imagefield

我是Django的新手，试图创建一个通过Django管理员上传图片的网站

我试图在HTML中查看上传到Imagefield中的图像。 但我就是不能让图像正常工作

Banner.objects.all（）似乎无法获取媒体文件夹中的所有图像文件

url.py

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('blog.urls')),
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

models.py

from django.db import models
from django.db.models.signals import pre_delete
from django.dispatch.dispatcher import receiver
from django.utils import timezone
from django.contrib.auth.models import User
from PIL import Image

class Post(models.Model):
    title = models.CharField(max_length=100)
    content = models.TextField()
    date_posted = models.DateTimeField(default=timezone.now) #auto_now=True //auto date
    author = models.ForeignKey(User, on_delete=models.CASCADE)

    def __str__(self):
        return self.title

class Banner(models.Model):
    title = models.CharField(max_length=100)
    images = models.ImageField(upload_to='images',null=True,blank=True)

    def __str__(self):
        return self.title

views.py

from django.shortcuts import render
from django.views.generic import(
    ListView,
    DetailView
)

from .models import *

# Create your views here.
class PostListView(ListView):
    model = Post
    template_name = 'blog/home.html'
    context_object_name = 'posts'
    ordering = ['-date_posted'] #arrange date posted with latest on top
    paginate_by = 6

def Banner_view(request):
    banner = Banner.objects.all()
    return render(request, 'blog/home.html',{'banner':banner})

设置.py

STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, 'static'),
]
STATIC_ROOT = os.path.join(BASE_DIR, 'static_root')

#uploaded file in base directory "media"
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
MEDIA_URL = '/media/'

home.html

  {% for b in banner %}
  <div>
    <img src="{{ b.images.url }}">
  </div>
  {% endfor %}

{%b在banner%}
{%endfor%}

你应该这样写 您应该使用

/

进行路径检测

images = models.ImageField(upload_to='images/', null=True,blank=True)
