How do I create custom converters in Django?

To create custom converters in Django, you need to define a class that inherits from django.urls.converters.StringConverter.

Can you give me an example of a custom converter?

Sure! Here's a simple example:

from django.urls import register_converter

class FloatConverter:
    regex = '[0-9]+(?:\.[0-9]+)?'

    def to_python(self, value):
        return float(value)

    def to_url(self, value):
        return str(value)

register_converter(FloatConverter, 'float')

How do I use this converter in my URL patterns?

You can use the custom converter in your URL patterns like this:

from django.urls import path

urlpatterns = [
    path('item/<float:value>/', views.item_view),
]

What if I want to create a converter for a specific format?

You can customize the regex in your converter class to match the specific format you need. Just update the regex attribute.
