The other day I stumbled on Sandi Metz's [rules](https://gist.github.com/henrik/4509394), and one of them reads

Still pretty new to Rails, but I always thought that my controller methods had some smell in them, and this confirmed it. I have a dashboard view for a parent model that displays information about their children (a different model) and the children's challenges(another model), all with different controllers. Here is an example of one of our controller methods.

```
def dash
  @parent = current_user
  @children = @parent.children
  @completed_challenges = @parent.assigned_challenges.where("parent_id =?", @parent.id).where("completed =?", true)
  @validated_challenges = @parent.assigned_challenges.where("parent_id =?", @parent.id).where("validated =?", true)
  @enabled_rewards = @parent.enabled_rewards.where("parent_id =?", @parent.id)
end

```

I was wondering if I could send multiple requests to get all of these objects from their respective controllers as opposed to lumping them all in one request. I know I can do this with Ajax, but is there a way just doing multiple http requests when the page is loading?

I appreciate the help!
