Pydantic Factories

  • New: Creating your custom factories.

    If your model has an attribute that is not supported by pydantic-factories and it depends on third party libraries, you can create your custom extension subclassing the ModelFactory, and overriding the get_mock_value method to add your logic.

    from pydantic_factories import ModelFactory
    class CustomFactory(ModelFactory[Any]):
        """Tweak the ModelFactory to add our custom mocks."""
        def get_mock_value(cls, field_type: Any) -> Any:
            """Add our custom mock value."""
            if str(field_type) == "my_super_rare_datetime_field":
                return cls._get_faker().date_time_between()
            return super().get_mock_value(field_type)

    Where cls._get_faker() is a faker instance that you can use to build your returned value.


  • New: Resolve the 422 error.

    You're probably passing the wrong arguments to the POST request, to solve it see the text attribute of the result. For example:

    result =
        json={"body": body},

    The error is telling us that the required url parameter is missing.

  • New: How to extract information from AWS WAF.

    AWS WAF is a web application firewall that helps protect your web applications or APIs against common web exploits and bots that may affect availability, compromise security, or consume excessive resources. AWS WAF gives you control over how traffic reaches your applications by enabling you to create security rules that control bot traffic and block common attack patterns, such as SQL injection or cross-site scripting. You can also customize rules that filter out specific traffic patterns.

    In the article there are many queries you can do on it's data and a workflow to understand your traffic.

    Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions.


Aerial Silk

  • New: Introduce Aerial Silk, some warmups and some figures.

    Aerial Silk is a type of performance in which one or more artists perform aerial acrobatics while hanging from a fabric. The fabric may be hung as two pieces, or a single piece, folded to make a loop, classified as hammock silks. Performers climb the suspended fabric without the use of safety lines and rely only on their training and skill to ensure safety. They use the fabric to wrap, suspend, drop, swing, and spiral their bodies into and out of various positions. Aerial silks may be used to fly through the air, striking poses and figures while flying. Some performers use dried or spray rosin on their hands and feet to increase the friction and grip on the fabric.
