An alternative and cleaner syntax is to nest the hash conditions:
```ruby
time_range = (Time.now.midnight - 1.day)..Time.now.midnight
-Client.joins(:orders).where(orders: {created_at: time_range})
+Client.joins(:order).where(orders: {created_at: time_range})
```
This will find all clients who have orders that were created yesterday, again using a `BETWEEN` SQL expression.
