Production / Development Only

Imagine you are coding a new feature but don´t want it to be available for users yet. But you need to fix bugs etc. the same time so you have to push updates. This library solves this problem: There are different features that make specific code only available in production or development use, specified by django´s very own DEBUG setting.

INSTALLED_APPS += ['django_additional_tools']

Views

Use

from django_additional_tools.django_production_development_only.tags import production_only

@production_only
def my_view(request):
    return render(request, 'my_template')

or

from django_additional_tools.django_production_development_only.tags import development_only

@development_only
def my_view(request):
    return render(request, 'my_template')

to make a whole view only available in production or development mode.

Templates

Use

{% load production %}

{% if production %}
    <h1>You´re in production mode</h1>
{% endif %}

or

{% load development %}

{% if development %}
    <h1>You´re in development mode</h1>
{% endif %}

to make a whole view only available in production or development mode.

If-Clauses

Use

from django_additional_tools.django_production_development_only.ifs import production_only

def my_view(request):
    if production_only:
        print('You´re in production mode')
    return render(request, 'my_template')

or

from django_additional_tools.django_production_development_only.ifs import development_only

def my_view(request):
    if development_only:
        print('You´re in development mode')
    return render(request, 'my_template')

Content Security Policy

Add a content security policy to your website to secure it.

MIDDLEWARE += ['django_additional_tools.middleware.generate_csp_nonce_middleware']
# Add your configuration data here, e.g. the allowed script sources

# Your CSP will look like this
csp = (
    "default-src 'self'; "
    f"script-src 'self' 'nonce-{script_nonce}' {settings.CSP_ALLOWED_SCRIPT_DATA}; "
    f"style-src 'self' 'nonce-{style_nonce}' {settings.CSP_ALLOWED_SCRIPT_DATA}; "
    f"img-src 'self' {settings.CSP_ALLOWED_IMG_DATA}; "
    f"frame-src {settings.CSP_ALLOWED_FRAME_DATA}; "
    f"connect-src 'self' {settings.CSP_CONNECT_DATA}; "
    f"media-src {settings.CSP_ALLOWED_MEDIA_DATA}"
)
# You can configure CSP_ALLOWED_SCRIPT_DATA etc. in the settings.
