`extra_params`
--------------



`extra_params` is used to provide extra parameters, on top of the parameters already provided by Django and the iommi path machinery:

.. code-block:: python

    def some_function(a, b):
        return a + b

    class IommiPage(Page):
        class Meta:
            @staticmethod
            def extra_params(request, a, b):
                return dict(
                    c=some_function(a, b),
                )

        content = Template('{{ params.a }} + {{ params.b }} = {{ params.c }}')

    iommi_view = IommiPage().as_view()

.. raw:: html
