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.
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.
// Use ~ with indexOf to test presence | |
hasAnF="This sentence has an f.".indexOf("f")>=0 // before | |
hasAnF=~"This sentence has an f.".indexOf("f") // after | |
// Both of these operator combos will floor numbers (note that since ~ has lower precedence than |, they are not identical). | |
rand10=Math.floor(Math.random()*10) // before | |
rand10=0|Math.random()*10 // after | |
# Send a metric to statsd from bash | |

// $('img.photo',this).imagesLoaded(myFunction) | |
// execute a callback when all images have loaded. | |
// needed because .load() doesn't work on cached images | |
// Modified with a two-pass approach to changing image | |
// src. First, the proxy imagedata is set, which leads | |
// to the first callback being triggered, which resets | |
// imagedata to the original src, which fires the final, | |
// user defined callback. |
