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 path4. 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')

</html>6. migraiton
