5.views.py

def upload(request):

　　if request.method == 'POST':
　　　　file = request.FILES.get('img',None)
　　　　name = request.POST.get('img')
　　　　print(name)

　　　models.Test.objects.create(name=1,image=file)
  img = models.Test.objects.all()
  return render(request, 'upload.html',{'img':img})

6.urls添加

from django.conf import settings
from django.conf.urls.static import static
。。。。] + static(settings.MEDIA_URL,document_root=settings.MEDIA_ROOT)

7.html 这样能显示完全
{% for i in img %}
<img src="{{ MEDIA_URL }}{{ i.image }}">
{% endfor %}

添加文件：
<form action="/upload/" method="post" enctype="multipart/form-data">
<input type="file" name="img">上传文件</input>
</form>
