Question

在搜索了几个小时但没有解决问题的解决方案之后，我发布了这个。来自我的媒体根目录的图片没有显示在我的html上。在chrome的控制台中，我得到一个404 file not found。即使图像在那里。我在Pycharm中使用Python 3，Django 1.10。

这是模型，我将图片上传到：

from django.db import models

class Post(models.Model):
    username = "anonymous"
    post = models.ImageField(upload_to='anon')
    creation_date = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return Post.username

views.py ：

from django.shortcuts import render,get_object_or_404
from .models import Post

def home(request):
    return render(request,"base.html",{})

def post_detail(request,id=None):
    instance = get_object_or_404(Post,id=id)
    context = {
        "post": instance.post,
        "instance": instance
    }
    return render(request,"post_detail.html",context)

post_detail.html （此处图片未显示）：

<body>
    <img src = "{{ instance.post.url}}" height="520" width="500"><br>
    {{ instance.creation_date }}<br>
    {{ instance.username }}<br>
</body>

我的目录是什么样的：

Answer 1

混淆静态和媒体设置是一个常见的错误。在您的情况下，您实际处理的是用户上传的MEDIA而不是STATIC。

 <img src = "{{ instance.post.url}}" height="520" width="500"><br>

最相关的设置是此处描述的MEDIA_ *设置 https://docs.djangoproject.com/en/1.10/howto/static-files/

但更重要的是，在您的开发服务器中，您需要通过添加

来启用MEDIA的传送

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

urlpatterns = [
    # ... the rest of your URLconf goes here ...
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

Django静态媒体没有显示图片
