NOTE For Windows users, replace pip3 with pip and python3 with python in all following commands.
The Virtual Environment
Virtual environments are used to keep separate project packages from the main computer, so you can use different versions of packages across different projects and ease deployment server setup.
$ pip3 install virtualenv
to install virtualenv system-wide.
Then in your Go directory run:
$ virtualenv -p python3 .venv
to create your virtual environment in the .venv directory.
Activate it by typing:
$ source .venv/bin/activate (Linux/Mac) or .venv\Scripts\activate.bat (Windows)
If you ever need to exit your virtual environment, simply run:
Now, the packages you need to install for Go are in in the top level of the project's directory structure(go/).
$ pip3 install -r requirements.txt
to install all of the packages needed for the project.
Go is configured for use with a mysql database.
Load up the mysql shell by running
$ mysql -u root -p
and putting in your mysql password.
Create the database by running:
> CREATE DATABASE go;
You can choose a different name for your database if you desire.
Double check your database was created by running:
> SHOW DATABASES;
Though you can use an existing user to access this database, here's how to create a new user and give them the necessary permissions to your newly created database:
> CREATE USER 'go'@'localhost' IDENTIFIED WITH mysql_native_password BY 'go';
Run to give the go user permission to the go database:
> GRANT ALL ON go.* TO 'go'@'localhost';
This allows your database user to create all the tables it needs on the Go database. (Each model in each app's models.py is a separate table, and each attribute a column, and each instance a row.)
> GRANT ALL ON test_go.* TO 'go'@'localhost'; FLUSH PRIVILEGES;
When running test cases, django creates a test database so your 'real' database doesn't get screwed up. This database is called 'test_' + whatever your normal database is named. Note that for permissions it doesn't matter that this database hasn't yet been created.
The .* is to grant access all tables in the database, and 'flush privileges' reloads privileges to ensure that your user is ready to go.
Exit the mysql shell by typing:
Change directory into go/go/ and run:
$ python3 manage.py makemigrations
to create the tables and rows and columns for your database. This command generates sql code based on your database models.
$ python3 manage.py migrate
to execute that sql code and set up your database. Migrations also track how you've changed your models over the life of your database, which allows you to make changes to your tables without screwing up existing information.
$ python3 manage.py createsuperuser
to create an admin account, using the same username and email as you'll access through CAS. This means your 'full' email address, for instance firstname.lastname@example.org. Your password will be handled through CAS, so you can just use 'password' here.
(If you accidentally skip this step, you can run python manage.py shell and edit your user from there. Select your user, and set .is_staff and .is_superuser to True, then save.)
Finally, within 'go/go' run:
$ python3 manage.py runserver
to start the site. Open your preferred web browser and navigate to 127.0.0.1:8000/ to see the site!
