How Django atomic requests works?
ATOMIC_REQUESTS is an an attribute of the database connection settings dict, not the top-level settings. So, for example:
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'mydatabase', 'USER': 'mydatabaseuser', 'PASSWORD': 'mypassword', 'HOST': '127.0.0.1', 'PORT': '5432', 'ATOMIC_REQUESTS': True, }}
