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.

    install Sinatra: gem install sinatra
    install Shotgun: gem install shotgun (this auto-reloads sinatra on every http request - which means every time you make a change in your code you don't have to stop then start sinatra)

    To just run your code using Sinatra: ruby name-of-file.rb
    To run your code using Shotgun (which is just Sinatra but with ability to auto-reload when changes are made to files): shotgun name-of-file.rb

    The following examples are run using Shotgun and the URL is: http://127.0.0.1:9393/

# When an RSpec test like this fails,
# 
#   @my_array.should == [@some_model, @some_model2]
# 
# RSpec will call inspect on each of the objects to "help" you figure out
# what went wrong. Well, inspect will usually dump a TON OF SHIT and make trying
# to figure out why `@my_array` is not made up of `@some_model` and `@some_model2`.
#
# This little module and technique helps get around that. It will redefine `inspect`
# if you include it in your model object.
