ActiveRecord Where Assoc
-
EXISTS clause for active record
I’ve been using the activerecord_where_assoc gem for this. I think it’s API is more natural than this proposal.
-
My new gem lets you follow associations when doing ActiveRecord queries. Here's an intro for follow_assoc.
Your examples using joins would return duplicated Sections. That might force you to add a distinct. I personally find it wrong to do a distinct in a scope just to be able to make the condition I want the scope to do. It's a hidden side effect that could cause problem elsewhere and it's unexpected from the name of the scope. I made a gem to deal with that situation: where_assoc. There is definitely an overlap between both gem.

A better CSV import
In the first step, we only validate if the information is all there and correctly formatted. For example, if a location name is missing, we highlight that error in the spreadsheet. If everything looks good, we save the locations to the database using the awesome Activerecord-Import library, but skip calling the geocoding API. Rather, we mark these locations as "to be geocoded".
