django test app error - Got an error creating the test database: permission denied to create database?

Question

When I try to test any app with command (I noticed it when I tried to deploy myproject using fabric, which uses this command): python manage.py test appname I get this error: Creating test database for alias 'default'... Got an error creating the test database: permission denied to create database Type 'yes' if you would like to try deleting the test database 'test_finance', or 'no' to cancel `syncdb` command seems to work. My database settings in settings.py: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'. 'NAME': 'finance', # Or path to database file if using sqlite3. 'USER': 'django', # Not used with sqlite3. 'PASSWORD': 'mydb123', # Not used with sqlite3. 'HOST': '127.0.0.1', # Set to empty string for localhost. Not used with sqlite3. 'PORT': '', # Set to empty string for default. Not used with sqlite3. } }

The error message you are seeing indicates that the user that Django is using to connect to the database does not have permission to create a new test database. Here are some steps you can take to resolve this issue:

1. Make sure that the user specified in your DATABASES settings (in this case, 'django') has the necessary privileges to create and delete databases.
2. If you're using PostgreSQL, connect to the database as a superuser and grant the necessary permissions to the 'django' user. For example, you can run the following command in the psql console:

GRANT ALL PRIVILEGES ON DATABASE finance TO django;

1. If the above steps don't work, try specifying a different user with the appropriate permissions in your DATABASES settings. For example, you could create a new user with the necessary permissions using the following SQL command:

CREATE USER myuser WITH CREATEDB PASSWORD 'mypassword';

And then update your DATABASES settings to use this new user:

DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'finance', 'USER': 'myuser', 'PASSWORD': 'mypassword', 'HOST': '127.0.0.1', 'PORT': '', } }

1. Finally, if none of the above steps work, you may need to check if there are any permission issues on your file system or with your database server setup. It's also possible that another process is currently locking the database, preventing Django from creating a new one.

I hope this helps you resolve the issue and run your tests successfully! Let me know if you have any further questions.
