Django 404、500页面全局配置知识点详解

urlpatterns = [
 ..............
]
handler404 = 'first.views.page_not_found' #handler404为固定写法，first.views.page_not_found为404处理函数的位置
handler500 = 'first.views.page_error' #同上

#全局404
def page_not_found(request,exception):
  from django.shortcuts import render_to_response
  response = render_to_response('first/404.html',{}) #first/404.html html页面
  response.status_code = 404
  return response

#全局500
def page_error(exception):
  from django.shortcuts import render_to_response
  response = render_to_response('first/500.html',{})
  response.status_code = 500
  return response

MEDIA_URL = '/media/' 
MEDIA_ROOT = os.path.join(BASE_DIR, "media")
STATIC_URL = '/static/'
STATICFILES_DIRS =[
  os.path.join(BASE_DIR, 'static'),
]
将
STATICFILES_DIRS =[
  os.path.join(BASE_DIR, 'static'),
] 注释
增加
STATIC_ROOT = os.path.join(BASE_DIR,'static')
保存后在URLS中添加
from django.urls import path,re_path
from tlmzp.settings import MEDIA_ROOT,STATIC_ROOT
from django.views.static import serve
urlpatterns = [
  ..................
  re_path(r'^media/(?P<path>.*)$', serve, {'document_root': MEDIA_ROOT}), #media文件
  re_path(r'^static/(?P<path>.*)$', serve, {'document_root': STATIC_ROOT}),#static文件
