Future Optimizations

• Add composite index on (content_type_id, object_id) to the Log model for faster lookups.
• Consider denormalizing the count on the project model for high-traffic projects.

Thanks Luke! I have added a couple of quick thoughts below:

• I hadn't realized that these logs only count logged-in users. I think this is okay, but we should make it very clear that this is the case (i.e. somehow explain that we are only counting registered users and that we are significantly undercounting true views).
• I wonder whether we should aggregate the count for all versions of a project (i.e. if a project has v1 and v2 then we combine the unique counts)? We could consider counting two counts: this version and all versions.
• Instead of "File views" we should say "Views" or "Project Views" (project is the term we use to describe any published resource).

Thanks! Instead of "Count of Registered Users", how about "Project Views by Unique Registered Users"?

Done @tompollard!

Thanks Luke, looks good to me. We will want to make some tweaks later (not completely happy with "Project Views by Unique Registered Users" and want to check exactly what we capture) but the addition of the number is step forward!
