Regular expression to match URLs

Here is a regular expression to match URLs, from http to the end.

(?:(?:https?|ftp):\/\/)(?:\S+(?::\S*)?@)?(?:(?!(?:10|127)(?:\.\d{1,3}){3})(?!(?:169\.254|192\.168)(?:\.\d{1,3}){2})(?!172\.(?:1[6-9]|2\d|3[0-1])(?:\.\d{1,3}){2})(?:[1-9]\d?|1\d\d|2[01]\d|22[0-3])(?:\.(?:1?\d{1,2}|2[0-4]\d|25[0-5])){2}(?:\.(?:[1-9]\d?|1\d\d|2[0-4]\d|25[0-4]))|(?:(?:[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9]+)(?:\.(?:[a-z\u00a1-\uffff0-9]-*)*[a-z\u00a1-\uffff0-9]+)*(?:\.(?:[a-z\u00a1-\uffff]{2,}))\.?)(?::\d{2,5})?(?:[/?#]\S*)?

FeinCMS installation

Following directions at https://feincms-django-cms.readthedocs.io/en/stable/installation.html, I ran into some problems, probably due to a Django version mismatch. I'm using Django 1.11.x. This second tutorial helped fill in some blanks: https://www.digitalocean.com/community/tutorials/how-to-install-and-get-started-with-feincms . Below are my additions to the first documentation link.

Don't add context processors to the default set Django startproject created.

Create a folder for templates. Add it to settings.py:

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
            os.path.join(BASE_DIR, 'my_project/templates'),
        ],

Create a template base.html with at least the following:

{% block content %}
    {% for content in feincms_page.content.main %}
        {{ content.render }}
    {% endfor %}
    {% endblock %}


{% block sidebar %}
    {% for content in feincms_page.content.sidebar %}
        {{ content.render }}
    {% endfor %}
    {% endblock %}

Create a new Django project in VSCode

                "Django"
            ]
        },

            "type": "python",
            "request": "launch",

                "runscript",
                "$(basename -s .py ${file})"
            ],
            "debugOptions": [
                "RedirectOutput",
                "Django"
            ]
        }
    ]
}

Static files

STATIC_URL: URL (relative to domain root) to trigger searching for static files.
STATICFILES_DIRS: List of directories in which to look for static files when collectstatic is run.
STATIC_ROOT: Django serves files from this directory when run under development mode. Also, collectstatic collects static files here. Upload this to server.

In development: project/static, sibling to project/manage.py
On production: /home/user/domain.com/public/static

settings.py:

STATIC_URL = '/static/'
STATICFILES_DIRS = [
    os.path.join(BASE_DIR, "static"),
]
STATIC_ROOT = os.path.join(os.path.dirname(BASE_DIR), 'public/static/')
