Django项目使用admin默认样式失效

解决方法：

# settings文件

'DIRS': [os.path.join(BASE_DIR, 'templates')],

STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')


# url文件

from django.urls import path, re_path
from django.conf import settings
from django.conf.urls.static import static
from django.views.static import serve

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path("static/(?P<path>.*)", serve, {'document_root': settings.STATIC_ROOT}),

] + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT)
