Last time we spoke of Django, we installed Django CMS: perhaps the most popular out-of-the-box CMS available for Django. Now that we've explored the most popular CMS, let's move on to the best CMS.
I realize I'm speaking of something subjective as though it were fact. As much as I'd like to agree that this is wrong, doing so would make for a boring read. I'll stick to my guns here.
To makes things easy, we'll start with the obligatory server updates and Python3 setup. This way, the copy-and-paste crew will have no problem following along. It's important to note that this example will take place on a Ubuntu server.
Let's get started by updating and upgrading our packages:
$ apt update $ apt upgrade -y
Next, we'll just make sure that we have the latest versi0ns of Python3, Python3-dev, and pip3 installed:
$ sudo apt install python3-pip python3-dev $ sudo -H pip3 install --upgrade pip
Finally, we'll follow best practices here by keeping our packages confirmed to a virtual environment we create:
$ python3 -m venv mysite/env $ source mysite/env/bin/activate
Great. With the environment activated, we can start getting to work. Before installing Wagtail, we need to install two dependencies:
zlib. These are libraries critical to image compression and the sort:
$ pip3 install libjpeg zlib
Now we can install Wagtail:
$ pip3 install wagtail
Good job. For our next trick, we'll create our actual Wagtail project. This installation contains Django at its core: simply installing Wagtail with install Django and create the necessary project structure. I'll be creating the project in the
/var/www directory, but feel free to do as you please.
$ mkdir /var/wwww $ cd /var/www $ wagtail start mysite $ cd mysite
wagtail start mysite is a command that will create a project called mysite in the current directory. Again, name your project as you see fit. With that directory created, change directories so you're inside said project, and install Wagtail dependencies from the
$ pip3 install -r requirements.txt
As with a normal Django project, we need to run our migrations to get things set up.
$ python3 manage.py migrate
This command will result in the following output:
Operations to perform: Apply all migrations: admin, auth, contenttypes, home, sessions, taggit, wagtailadmin, wagtailcore, wagtaildocs, wagtailembeds, wagtailforms, wagtailimages, wagtailredirects, wagtailsearch, wagtailusers Running migrations: Applying contenttypes.0001_initial... OK Applying auth.0001_initial... OK Applying admin.0001_initial... OK Applying admin.0002_logentry_remove_auto_add... OK Applying admin.0003_logentry_add_action_flag_choices... OK Applying contenttypes.0002_remove_content_type_name... OK Applying auth.0002_alter_permission_name_max_length... OK Applying auth.0003_alter_user_email_max_length... OK Applying auth.0004_alter_user_username_opts... OK Applying auth.0005_alter_user_last_login_null... OK Applying auth.0006_require_contenttypes_0002... OK Applying auth.0007_alter_validators_add_error_messages... OK ...
Next, we need to created a superuser:
$ python3 manage.py createsuperuser
Running this will prompt a few details as follows:
Username (leave blank to use 'root'): myuser Email address: email@example.com Password: Password (again): Superuser created successfully.
You're a hero. Now, you're probably anxious to see what all the fuss is about. Let's get your development server up and running so you can start playing around in the browser:
$ python manage.py runserver
That command should give you the following:
Performing system checks... System check identified no issues (0 silenced). April 20, 2019 - 03:48:58 Django version 2.1.8, using settings 'mysite.settings.dev' Starting development server at http://127.0.0.1:8000/ Quit the server with CONTROL-C.
Great work. Now if you visit your server's default address on port 8000, you should be able to hit the barebones Wagtail project you just created. To reach the admin, hit http://localhost:8000/admin/.
As mentioned, installing Wagtail will immediately set up a Django project. If that's so, where is our famous
settings.py file? It's actually split into three files:
production.py. All these are stored here:
$ cd mysite/settings
base.py is the closest to Django's
settings.py file. This contains all settings which are common to both our dev and prod environments.
As you might imagine, settings stored in either
production.py are specific to dev or production, respectively.
dev.py comes with some presets, such as setting
True, as well as a pre-populated
from .base import * # SECURITY WARNING: don't run with debug turned on in production! DEBUG = True # SECURITY WARNING: keep the secret key used in production secret! SECRET_KEY = 'i!9r654&2us(2g!2ep#n*vufp-)z#mn+^qid_w8o^thnsj)nbm' # SECURITY WARNING: define the correct hosts in production! ALLOWED_HOSTS = ['*'] EMAIL_BACKEND = 'django.core.mail.backends.console.EmailBackend' try: from .local import * except ImportError: pass
production.py comes with no such predetermined values. The understanding is that you must set these values yourself: after all, if anybody were to grab a hold of the secret kept in
production.py, your career as a developer is basically over:
from .base import * DEBUG = False try: from .local import * except ImportError: pass
