The found solutions/approaches for t...

I've a post model with act-as-taggable-on gem. Both tables have timestamps. I started with def tags @posts = current_user.posts.find_tagged_with(params[:tag], :order => "@posts.tags.updated_at DESC"]) end And when that didn't work, I tried changing things and ended up with this mess. def tags @posts = current_user.posts.find_t...
