Third party services (e.g. Stripe) optionally sign webhook events to verify it is them sending events. If the third party you use does not provide an SDK or official library for verifying signatures, you can manually verify the signature with this snippet.

This snippet shows how to add a `url` field to your API objects, which will then show up as an object in your JSON output. As parameters, you can specify: - `urls`: A list of strings that exist on your URLMan class - `attribute`: The name of the URLMan class on your model, defaults to `"urls"` - `full`: If the full URLs including schema and hostname should be supplied, defaults to `True`
This middleware uses Django's Geoip support (https://docs.djangoproject.com/fr/2.2/ref/contrib/gis/geoip2/), as well as axes's package helper to retrieve IP address (since Django's REMOTE_ADDR might be wrong when behind a reverse proxy). Ensure your geolite DB files are up to date (eg. with https://djangosnippets.org/snippets/10674/). The checker is optional, but ensures that security is not broken due to a misspelled/missing GEOIP_COUNTRY_WHITELIST.
This management command updates country and city Geolite databases from Maxmind (binary databases, not CSV ones), for use with Django's builtin Geoip utilities.
Use this to display an object on a page AND be able to process a form on this page. This is just a copy of the [Django docs advice](https://docs.djangoproject.com/en/2.2/topics/class-based-views/mixins/#using-formmixin-with-detailview), but put as a reusable, standalone View.
A form field for a Boolean that forces the user to make a choice from a list of choices. **Use Case** You have a Yes/No question the user must answer, but they may answer it yes or no. You don't want to supply a default because your need to force the user to actively select their answer. If they do not select an answer, the field should raise a validation error, like "This field is required". Normal BooleanField logic is based on a "checkbox", which, when "required" is required to be checked. This logic assumes that an empty value is the same as False -- in fact, there is no way for validators to distinguish between the empty value and False. Based on excellent suggestion from Peter DeGlopper: https://stackoverflow.com/a/56677670/1993525
Requires to install "basicauth" package, which does basic-auth header encoding/decoding cleanly according to RFCs. Could be improved to return a "realm" in case of http401, like in https://djangosnippets.org/snippets/1720/, although I'm not sure it's really useful in django usecases.
Django's CharField requires a max_length, and TextField displays a multi- line widget, but in Postgres there's no reason to add an arbitrary max thanks to the `varlena` storage format. So this is a TextField that displays as a single line instead of a multiline TextArea.
