Django静态媒体没有显示图片

Question

after searching for a solution for hours which did not resolve my problem,I am posting this. 在搜索了几个小时没有解决我问题的解决方案之后，我发布了这个。 The image from my media root is not showing up on my html. 来自我的媒体根目录的图片没有显示在我的html上。 In chrome's console i get a 404 file not found .Even though the image is there. 在chrome的控制台中，我404 file not found 。即使图像在那里。 I am using Python 3 ,Django 1.10 in Pycharm. 我在Pycharm中使用Python 3，Django 1.10。

This is the model which is where i upload images to: 这是我将图像上传到的模型：

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 : 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 (here the image isnt showing): 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>

It's a common mistake to mix up the static and media settings. 混淆静态和媒体设置是一个常见的错误。 In your case what you are actually dealing with is user uploaded MEDIA and not STATICs. 在您的情况下，您实际处理的是用户上传的MEDIA而非STATIC。

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

The settings that are most relevent are MEDIA_* settings described here https://docs.djangoproject.com/en/1.10/howto/static-files/ 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/

But more importantly, in your dev sever you need to enable the delivery of MEDIA by adding 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的传递

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)
