The next steps assume that conda is already installed
1 - Create a conda environment:
conda create python=3.8 -n cookiecutter
2 - Activate the conda environment
conda activate cookiecutter
3 - Install the project basic dependencies and development dependencies
Make sure you are inside the root project directory before executing the next commands.
The root project directory is the directory that contains the
manage.py
file
On Linux and Mac
pip install -r requirements/local.txt
On Windows
pip install -r requirements\local.txt
4 - Configure the database connection string on the .env
On Linux and Mac
cp env.sample.mac_or_linux .env
On Windows
copy env.sample.windows .env
Change the value of the variable DATABASE_URL
inside the file .env
with the information of the database we want to connect.
Note: Several project settings have been configured so that they can be easily manipulated using environment variables or a plain text configuration file, such as the .env
file.
This is done with the help of a library called django-environ. We can see the formats expected by DATABASE_URL
at https://github.com/jacobian/dj-database-url#url-schema.
5 - Use the django-extension's sqlcreate
management command to help to create the database
On Linux:
python manage.py sqlcreate | sudo -u postgres psql -U postgres
On Mac:
python manage.py sqlcreate | psql
On Windows:
Since there is no official support for PostgreSQL 12 on Windows 10 (officially PostgreSQL 12 is only supported on Windows Server), we choose to use SQLite3 on Windows
6 - Run the migrations
to finish configuring the database to able to run the project
python manage.py migrate
coverage run -m pytest
If for some reason you get an error similar to bellow, is because the DATABASE_URL is configured to postgres:///cookiecutter
and because of it the generated DATABASES
settings are configured to connect on PostgreSQL using the socket mode.
In that case, you must create the database manually because the sqlcreate
is not capable to correctly generate the SQL query in this case.
ERROR: syntax error at or near "WITH"
LINE 1: CREATE USER WITH ENCRYPTED PASSWORD '' CREATEDB;
^
ERROR: zero-length delimited identifier at or near """"
LINE 1: CREATE DATABASE cookiecutter WITH ENCODING 'UTF-8' OWNER "";
^
ERROR: syntax error at or near ";"
LINE 1: GRANT ALL PRIVILEGES ON DATABASE cookiecutter TO ;
ERROR: role "myuser" already exists
ERROR: database "cookiecutter" already exists
GRANT
You can delete the database and the user with the commands below and then perform step 5 again.
⚠️ Be very careful here!: The commands below erase data, and should only be executed on your local development machine and NEVER on a production server.
On Linux:
sudo -u postgres dropdb -U postgres --if-exists cookiecutter
sudo -u postgres dropuser -U postgres --if-exists myuser
On Mac:
dropdb --if-exists cookiecutter
dropuser --if-exists myuser
