Render and Redirect

The normal controller/view flow is to display a view template corresponding to the current controller action, but sometimes we want to change that. We use render in a controller when we want to respond within the current request, and redirect_to when we want to spawn a new request.

Render

The render method is very overloaded in Rails. Most developers encounter it within the view template, using render :partial => 'form' or render @post.comments, but here we'll focus on usage within the controller.

`:action`

Bower

Set up the bower gem.
Follow the Bower instructions and list your dependencies in your bower.json, e.g.
```
// bower.json
```

What are we trying to observe? Raw object data.

// Objects
var obj = { id: 2 };
obj.id = 3; // obj == { id: 3 }
 
// Arrays
var arr = ['foo', 'bar'];
arr.splice(1, 1, 'baz'); // arr == ['foo', 'baz'];

	# Both algorithm sort in O(n * lg(n)) time

	if to == nil
	# Sort the whole array, by default
	to = array.count - 1
