Pydantic 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."""

    @classmethod
    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.

FastAPI ⚑

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 = client.post(
    "/source/add",
    json={"body": body},
)

result.text
```
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.
