Hey Jeremy,
I wanted to use eager or eager_graph to easily fetch and cache a non-
predefined association. The thing I want to speed up is this:
Post.each do |post|
post.comments.filter(:user_id => params[:id]).first
end
As you can see, I need to filter and limit the associated table
dynamically (against some argument, in this case params[:id]).
I feel like there would be something to the effect of:
Post.eager_graph(:comments).eager_filter(:user_id => params
[:id]).eager_limit(1)
but I can't find it.
Can you help me with this?
