使用cookiecutter-django创建的项目未运行

Question

Its been a few months that I am trying to learn Django. In the same process (and while reading "Two Scoops of Django 1.11"), I came across Cookiecutter Django. It has helped me learn a few important things to keep in mind while creating a project.

I tried to run the template provided by cookiecutter-django but failed. Here are the steps that I followed.

1. Create a virtual environment named test and activate it.

mkvirtualenv test

2. Installed Cookiecutter .

pip install coockiecutter

3. Installed Cookiecutter Django , The project name was set to "Test Project" and other defaults settings were chosen. I am using PostgreSQL 9.6. cookiecutter https://github.com/pydanny/cookiecutter-django
4. Create a database named "test_project" in PostgreSQL.
5. Run python manage.py migrate

The result was the error:

django.db.utils.OperationalError: FATAL:  role "dev" does not exist

I have also tried making a user named test_project_user and granting it all the privileges to test_project database. I am still getting the same error.

The problem seems to be that you specified a database user that does not exist (or you left blank and it assumes your system user), in:

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.postgresql',
        'NAME': 'test_project',
        'USER': 'HERE', # Set test_project_user here
        ...
    }
}
