Question

A user has_many badges through badge_awardings

I can do

@user.badges.count(:group => 'badges.id')

Which returns a hash of ids and counts like this

{1=>2, 2=>1, 5=>1, 8=>1}

But then I have to find the badges again individually to display them.

Is there anyway of returning a hash of badges and their counts?

Answer 1

You can get the badges in another step:

badge_count = @user.badges.count(:group => 'badges.id')
badges = Badge.find(badge_count.keys)
badges_counted = badges.inject({}){ |h, v| h.update(v => badge_count[v.id]) }
