This is "Error:-2" ... [ When DEBUG=True ]

But at time of ' DEBUG=True ' my admin page is open but it gives below error in terminal.

[15/Mar/2020 11:15:51] "GET /admin/login/?next=/admin/ HTTP/1.1" 200 1913

When ever i try to open '/admin/' in my browser i will gives an error, But my home page [ 127.0.0.1:8000 ] it's working properly.

thanks in advance.

Answer 1

**Finally error can solve ..**

we can remove only three line from settings.py

1> django_heroku.settings(locals()) this line is require for deployment Django app on Heroku.

2> STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage'

3> MIDDLEWARE = [ ... 'whitenoise.middleware.WhiteNoiseMiddleware', ]

2nd and 3rd line are use for serve static files on website when DEBUG=False.

after removing this three line error can solve and, It will run perfectly without any error.

thank you and special thank you for Alasdair .
