Question

getting the below error while running makemigrations

Traceback (most recent call last): File "/home/siva/venv/lib/python3.8/site-packages/django/db/backends/base/base.py", line 217, in ensure_connection self.connect() File "/home/siva/venv/lib/python3.8/site-packages/django/db/backends/base/base.py", line 195, in connect self.connection = self.get_new_connection(conn_params) File "/home/siva/venv/lib/python3.8/site-packages/django/db/backends/postgresql/base.py", line 178, in get_new_connection connection = Database.connect(**conn_params) File "/home/siva/venv/lib/python3.8/site-packages/psycopg2/ init .py", line 127, in connect conn = _connect(dsn, connection_factory=connection_factory, **kwasync) psycopg2.OperationalError: FATAL: password authentication failed for user "postgres" FATAL: password authentication failed for user "postgres"

The above exception was the direct cause of the following exception:
