We all learn very early in playing with django to set a site and a SITE_ID. Once we operate as multiple sites, we either use the multiple processes, each configured with a separate SITE_ID or we can now pass a request in. However, I assume for backward compatibility, SITE_ID must be removed. This allows all sites which specify SITE_ID to operate as if the addition of passing request was not added. However, removing SITE_ID to allow get_site_by_request breaks all applications which do NOT pass request, because there is no SITE_ID.
I propose a setting, which, when set to True in addition to setting SITE_ID, causes request to take precedence over SITE_ID. This will allow applications using both paradigms to coexist without modification - sites which pass request use get_site_by_request as if SITE_ID had not been defined and calls passing no request get SITE_ID. When the new setting is not present, all behavior is backward compatible. Essentially, I am proposing something like the 'change set' I typed in below - I considered that a complex and/or in the fist if could cover all of the conditions, but I think qualifying the first line with the new setting and adding the elif to cover the cleanup case of not set to True is easier to understand - especially in light of understanding the the backward compatibility aspect of the change. The version of this change I am currently running simply defines a new SITE_DEFAULT_ID to catch the third case, but it occurred to me that some modules may expect SITE_ID directly for some reason, and MIXED_MODE has them covered too. I expect the documentation change to accompany the new setting would go with the Sites documentation next to SITE_ID an explanation of removing SITE_ID to use request. This would be my first contribution, so I am unsure that it would welcome. If this ticket is accepted, I will quite gladly prepare a pull request with an agreed upon setting name (in case mine doesn't grab ya) or other any other suggested style improvements etc. def get_current(self, request=None): """ Return the current Site based on the SITE_ID in the project's settings.
