Creating the app for the blog

Now let's create a new Django application. We'll call our new app main.

$ django-admin startapp main

Once the app is created, we'll have to move the app in the blog_tutorial directory together with the default users app and configure our apps.py, urls.py, and include the app in our base.py config. Let's now create those files and configure it for our app.

Our blog_tutorial/main/apps.py is configured as follow:

# blog_tutorial/main/apps.py
from django.apps import AppConfig
from django.utils.translation import gettext_lazy as _

class MainConfig(AppConfig):
    name = 'blog_tutorial.main'
    verbose_name = _("Main")

    def ready(self):
        try:
            pass
        except ImportError:
            pass

And our blog_tutorial/main/urls.py has an empty urlpatterns variable. This is because we will be defining all our URLs in the config/urls.py file.

# blog_tutorial/main/urls.py
app_name = "main"
urlpatterns = [ ]

And don't forget to add our app to the LOCAL_APPS in the config/settings/base.py

# config/settings/base.py

...
LOCAL_APPS = [
    "blog_tutorial.users.apps.UsersConfig",
    # Your stuff: custom apps go here
    "blog_tutorial.main.apps.MainConfig",
]

Then let's apply our migrations and run our app.

$ python manage.py migrate

Ok, bye. Thanks for listening to my Ted talk.

Kidding.

You can check the official docs of Cookiecutter-Django to get more information on the features of the framework. https://cookiecutter-django.readthedocs.io/en/latest/developing-locally.html

In this chapter, we've installed a virtual environment to separate our project in our development environment, install the default project dependencies of Cookiecutter-Django, created a PostgreSQL database, created a Django app and added the necessary config in our app and settings to make our Django blog work.
