  'DIRS': [os.path.join(BASE_DIR,'templates')],
  'APP_DIRS': True,
  'OPTIONS': {
   'context_processors': [

#picture path setting
MEDIA_ROOT = os.path.join(BASE_DIR, 'media').replace("\\", "/")
MEDIA_URL = '/media/'

urls.py

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


urlpatterns = [
 path('admin/', admin.site.urls),
 path('', views.index),
 path('upload/', include(('myupload.urls', 'myupload'), namespace='myupload')), # add uppoad urls
] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)      #add image path

4. app 设定

models.py

from django.db import models

class User(models.Model):
 name = models.CharField(verbose_name='姓名', max_length=10)
 avator = models.ImageField(verbose_name='头像', upload_to='upload/%Y/%m/%d')

admin.py

from django.contrib import admin
from .models import *
