You're using the Django "sites framework" without having set the SITE_ID setting.

Description

Using Django-sites, and classed based views and attempting to render a meta object using get_context_data(), I hit a roadblock which fails to render any meta headers and results in an error.

When setting...
    with META_USE_SITES = True
        - fails with:
            You're using the Django "sites framework" without having set the SITE_ID setting. Create a site in your database and set the SITE_ID setting or pass a request to Site.objects.get_current() to fix this error.

    without META_USE_SITES = False
        - it fails with:
            META_SITE_DOMAIN is not set?

Steps to reproduce

    def get_context_data(self, **kwargs):
        ctx = super().get_context_data(**kwargs)
        ctx['meta'] = Meta(
            request=self.request,
            title="A page title",
            image=static('image.png'),
        )
        return ctx

Versions

django 4.1.6 python 3.11.3

Expected behaviour

I would expect the page to render fine.

Actual behaviour

The page results in an error:

  "You're using the Django "sites framework" without having set the SITE_ID setting. Create a site in your database and set the SITE_ID setting or pass a request to Site.objects.get_current() to fix this error."

Additional information

If I remove the image line, it works fine.

I believe I've managed to locate the problem. The request object is not loaded until the final step of the init function, but it is used before it when rendering the image url.

If I override the meta class and move the line:

        self.request = kwargs.get("request", None)

to the top, this works.

As a workaround I've extended the init function and moved the request object to the top, which works fine.
