Django项目中配置媒体文件路径的详细步骤与最佳实践

1、创建一个app02, 并在settings.py里面设置

2、在settings.py里面设置媒体文件保存的路径

from django.contrib import admin
from django.urls import path,re_path
from app01 import views
from django.views.static import serve
from LoginTest import settings

urlpatterns = [
  path('admin/', admin.site.urls),
  path("login/", views.login),
  path("index/", views.index),
  path("home/", views.home),
  path("logout/", views.logout),
  path("set_session/", views.setSession),

  #手动添加对外开放的后端服务器资源
  re_path(r"^media/(?P.*)/", serve, {"document_root": settings.MEDIA_ROOT}),
]

3、在app02/models.py里面， 创建一个模型，用于上传文件

from django.db import models

# Create your models here.
class UserDetail(models.Model):
  headPhoto = models.FileField(upload_to="head")
  hobby = models.TextField(max_length=200)

 4、执行makemiagrtions和migrate， 同步数据库

5、在app02/admin.py里面注册模型 UserDetail

from django.contrib import admin
from app02.models import UserDetail

# Register your models here.


admin.site.register( UserDetail)

6、创建超级用户admin, 并使用admin添加UserDetail

7、手动在浏览器里面访问http://127.0.0.1:8080/media/head/head1.jpg/
