format_suffix_patterns

The format_suffix_patterns module is a utility module provided by Django that allows you to specify the format suffixes that your API views can respond to.

For example, if you have a view that returns a list of objects in JSON format, you can use format_suffix_patterns to specify that the view should also respond to requests for XML or YAML formats.

To use format_suffix_patterns, you first need to import it:

from rest_framework.urlpatterns import format_suffix_patterns

Then, you can define your API views as you normally would, but with an additional parameter that specifies the format suffix:

@api_view(['GET'])
def my_view(request, format=None):
    # your view code here

Finally, you can use the format_suffix_patterns function to wrap your URL patterns:

urlpatterns = [
    path('my-view/', my_view),
]

urlpatterns = format_suffix_patterns(urlpatterns)

This will automatically generate URL patterns for each format suffix you specify, such as /my-view.json or /my-view.xml.

Note: If you're using class-based views, you can use the @renderer_classes decorator to specify the format suffixes that your view should respond to.
