urls.py 文件中

urlpatterns = [
    path('admin/', admin.site.urls),
    path(r'^blog/index/$','blog.views.index')
]


我可以通过ctrl+鼠标左键 找到 admin.site.urls ，但是点blog.views.index 显示 ‘can not find declaration to go to
’ 这个写法不对吗 如果去掉引号   blog会报红，导入也没用

叶小贤

urlpatterns = [
    path('admin/', admin.site.urls),
    path(r'^blog/index/$',blog.views.index)
]

上面代码中的 path('admin/', admin.site.urls)  是通过 from django.contrib import admin 导入的
那下面我自己配置的 怎么导入？
