Since this isn't a tutorial focused on the Cookiecutter-Django framework, I won't be getting too much into it. I'll only include how I fell in love with the framework when I found out what features it had that I struggled with implementing on the usual way to create a Django project. Some features included are Twitter bootstrap, django all-auth, sending emails using Anymail, media files storage using AWS S3, or GCP. It also comes with the custom user and supports Docker.

Open your terminal. Make sure you install cookiecutter on your machine. Otherwise, you'll run into an error.
$ pip install "cookiecutter>=1.7.0"
Now run this command:
$ cookiecutter https://github.com/pydanny/cookiecutter-django
You'll be asked for some values when you run the command. Be sure to run through the docs to avoid repeating this step.

Now change the directory into the project slug and try to get familiar with the folder structure. We'll be initializing a git repo inside the directory, committing our code, and pushing it to GitHub for version control. We're also creating a different environment for our blog using virtualenv to isolate our app's python project dependencies. Make sure you install the latest version found in https://pypi.org/project/virtualenv/. I'm using a mac, so my apologies for windows users if I don't execute windows commands in this tutorial.
$ cd blog_tutorial/
$ ls
$ git init
$ git add .
$ git commit -m "initial commit"
$ git remote add origin https://github.com/reyesvicente/blog_tutorial.git
$ git push -u origin master
Now that we've pushed our code to GitHub, let's create a virtual environment, activate it, and install the default packages included in the Cookiecutter-Django framework.
To install virtualenv, open our terminal, then execute:
$ python -m pip install --user virtualenv
Once the package is installed, check if you've installed the correct version by running:
$ virtualenv --version 0:08:50 virtualenv 20.0.27 from /Users/user/.local/lib/python3.8/site-packages/virtualenv/__init__.py
Now create the virtual environment by running:
$ virtualenv env # name of the virtual environment is env
Output:
created virtual environment CPython3.8.2.final.0-64 in 6874ms
creator CPython3Posix(dest=/Users/user/blog_tutorial/env, clear=False, global=False)
seeder FromAppData(download=False, pip=latest, setuptools=latest, wheel=latest, via=copy, app_data_dir=/Users/user/Library/Application Support/virtualenv/seed-app-data/v1.0.1)
activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
Once the virtual environment is created, let's activate the virtual environment and install the project dependencies. We'll also create a database using the createdb command, and we'll set the environment variables for our database. Make sure you have it on your machine if not, you can download it via Homebrew Cask or go to the Postgres App website and download it.
$ source env/bin/activate
$ python -m pip install -r requirements/local.txt
$ createdb blog_tutorial -U postgres --password <your_password>
$ export DATABASE_URL=postgres://postgres:<enter_your_psql_password>@127.0.0.1:5432/blog_tutorial
As of writing, the virtualenv package is at version 20.0.27.
You might be wondering why we need to install a virtual environment and isolate our project dependencies and install it globally. The reason is, if you have multiple projects in your development environment and you installed the project dependencies globally, there's a big chance that your app would crash. Let's get a little more info on that.
Imagine you have 2 Django projects. One uses a Django version 2.2.14, and the other uses Django 3.0.8. Both have different project dependencies that also have different versions in it.
In situations like this, it's a good practice to create separate virtual environments for the two projects since all Django projects are different, using other python packages.
