One little pet peeve of mine is that there is no way (afaik) to just add
additional columns to the select clause of a query. Like for example if I'm
joining and want a count or aggregate off the join table:
User.joins(:answers)
.select('users.*','AVG(answers.score) AS average_score')
What I would really want to do is just add this to the existing select
values of the scope:
User.joins(:answers)
.select_also('AVG(answers.score) AS average_score')
*Is this a worthwhile feature? *
