Question

I have a Django cookiecutter template. After performing all the required actions given on cookiecutter docs when I run python manage.py migrate I get this error

raise ImproperlyConfigured(
django.core.exceptions.ImproperlyConfigured: settings.DATABASES is improperly configured. Please supply the NAME value.
This is the settings base.py file (database setting part) which come by default with template
DATABASES = {
"default": env.db(
"DATABASE_URL",
default="postgres://localhost/task_manager_app",
),
}
DATABASES["default"]["ATOMIC_REQUESTS"] = True
I've set the database URL using command
export DATABASE_URL=postgres://postgres:mypass#127.0.0.1:5432/task_manager_app
Anyone help me out to get rid of this error.

Answer 1

First of all you have to do it as follows:
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.postgresql', #Make sure you have psycopg2 installed. It is postgresql connector.
'NAME': ‘DB NAME’,
'USER': 'DB USERNAME',
'PASSWORD': 'USER PASSWORD',
'HOST': 'HOST IP',
'PORT': 'PORT',#Generally 5432
}
}

Answer 2

After puzzling over it a lot, I got the solution. The problem was having the character "#" in my database password.
