Question

The databe setting for database in setting.py is:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql_psycopg2',
        'NAME': 'freecodeschool',
        'USER': 'fcs_admin',
        'PASSWORD': '',
        'HOST': 'localhost',
        'PORT': '',
    }
}

when i run migrations i got this error.

   return func(*args, **kwargs)
  File "/home/danish-khan/django_drf/django/lib/python3.8/site-packages/django/db/backends/postgresql/base.py", line 187, in get_new_connection
    connection = Database.connect(**conn_params)
  File "/home/danish-khan/django_drf/django/lib/python3.8/site-packages/psycopg2/__init__.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: fe_sendauth: no password supplied

   connection = Database.connect(**conn_params)
  File "/home/danish-khan/django_drf/django/lib/python3.8/site-packages/psycopg2/__init__.py", line 127, in connect
    conn = _connect(dsn, connection_factory=connection_factory, **kwasync)
django.db.utils.OperationalError: FATAL:  password authentication failed for user "fcs_admin"
FATAL:  password authentication

Answer 1

it seems you haven't filled PASSWORD and your db wants it for user "fcs_admin". beside that you should add your db PORT too. (default is 5432) if you're not sure about postgres users' password you can use these commands:

sudo su postgres
