# Action Controllers are made up of one or more actions that performs its purpose and then either renders a template or
# redirects to another action. An action is defined as a public method on the controller, which will automatically be
# made accessible to the web-server through a mod_rewrite mapping. A sample controller could look like this:
#
# class GuestBookController < ActionController::Base
# def index
# @entries = Entry.find_all
# end
#
# def sign
# Entry.create(params[:entry])
# redirect_to :action => "index"
# end
# end
#
# GuestBookController.template_root = "templates/"
# GuestBookController.process_cgi
#
# All actions assume that you want to render a template matching the name of the action at the end of the performance
# unless you tell it otherwise. The index action complies with this assumption, so after populating the @entries instance
# variable, the GuestBookController will render "templates/guestbook/index.rhtml".
#
# Unlike index, the sign action isn't interested in rendering a template. So after performing its main purpose (creating a
# new entry in the guest book), it sheds the rendering assumption and initiates a redirect instead. This redirect works by
# returning an external "302 Moved" HTTP response that takes the user to the index action.
#
# The index and sign represent the two basic action archetypes used in Action Controllers. Get-and-show and do-and-redirect.
# Most actions are variations of these themes.
#
# Also note that it's the final call to process_cgi that actually initiates the action performance. It will extract
# request and response objects from the CGI
#
# When Action Pack is used inside of Rails, the template_root is automatically configured and you don't need to call process_cgi
# yourself.
#
# == Requests
#
# Requests are processed by the Action Controller framework by extracting the value of the "action" key in the request parameters.
# This value should hold the name of the action to be performed. Once the action has been identified, the remaining
# request parameters, the session (if one is available), and the full request with all the http headers are made available to
# the action through instance variables. Then the action is performed.
#
# The full request object is available with the request accessor and is primarily used to query for http headers. These queries
# are made by accessing the environment hash, like this:
#
# def hello_ip
# location = request.env["REMOTE_IP"]
# render :text => "Hello stranger from #{location}"
# end
#
# == Parameters
#
# All request parameters, whether they come from a GET or POST request, or from the URL, are available through the params hash.
# So an action that was performed through /weblog/list?category=All&limit=5 will include { "category" => "All", "limit" => 5 }
# in params.
#
# It's also possible to construct multi-dimensional parameter hashes by specifying keys using brackets, such as:
#
#
#
#
# A request stemming from a form holding these inputs will include { "post" => { "name" => "david", "address" => "hyacintvej" } }.
# If the address input had been named "post[address][street]", the params would have included
# { "post" => { "address" => { "street" => "hyacintvej" } } }. There's no limit to the depth of the nesting.
#
# == Sessions
#
# Sessions allows you to store objects in memory between requests. This is useful for objects that are not yet ready to be persisted,
# such as a Signup object constructed in a multi-paged process, or objects that don't change much and are needed all the time, such
# as a User object for a system that requires login. The session should not be used, however, as a cache for objects where it's likely
# they could be changed unknowingly. It's usually too much work to keep it all synchronized -- something databases already excel at.
#
# You can place objects in the session by using the session hash accessor:
#
# session[:person] = Person.authenticate(user_name, password)
#
# And retrieved again through the same hash:
#
# Hello #{session[:person]}
#
# Any object can be placed in the session (as long as it can be Marshalled). But remember that 1000 active sessions each storing a
# 50kb object could lead to a 50MB memory overhead. In other words, think carefully about size and caching before resorting to the use
# of the session.
#
# For removing objects from the session, you can either assign a single key to nil, like session[:person] = nil, or you can
# remove the entire session with reset_session.
#
# == Responses
#
# Each action results in a response, which holds the headers and document to be sent to the user's browser. The actual response
# object is generated automatically through the use of renders and redirects, so it's normally nothing you'll need to be concerned about.
#
# == Renders
#
# Action Controller sends content to the user by using one of five rendering methods. The most versatile and common is the rendering
# of a template. Included in the Action Pack is the Action View, which enables rendering of ERb templates. It's automatically configured.
# The controller passes objects to the view by assigning instance variables:
#
# def show
# @post = Post.find(params[:id])
# end
#
# Which are then automatically available to the view:
#
# Title: <%= @post.title %>
#
# You don't have to rely on the automated rendering. Especially actions that could result in the rendering of different templates will use
# the manual rendering methods:
#
# def search
# @results = Search.find(params[:query])
# case @results
# when 0 then render :action=> "no_results"
# when 1 then render :action=> "show"
# when 2..10 then render :action=> "show_many"
# end
# end
#
# Read more about writing ERb and Builder templates in link:classes/ActionView/Base.html.
#
# == Redirects
#
# Redirecting is what actions that update the model do when they're done. The save_post method shouldn't be responsible for also
# showing the post once it's saved -- that's the job for show_post. So once save_post has completed its business, it'll
# redirect to show_post. All redirects are external, which means that when the user refreshes his browser, it's not going to save
# the post again, but rather just show it one more time.
#
# This sounds fairly simple, but the redirection is complicated by the quest for a phenomenon known as "pretty urls". Instead of accepting
# the dreadful being that is "weblog_controller?action=show&post_id=5", Action Controller goes out of its way to represent the former as
# "/weblog/show/5". And this is even the simple case. As an example of a more advanced pretty url consider
# "/library/books/ISBN/0743536703/show", which can be mapped to books_controller?action=show&type=ISBN&id=0743536703.
#
# Redirects work by rewriting the URL of the current action. So if the show action was called by "/library/books/ISBN/0743536703/show",
# we can redirect to an edit action simply by doing redirect_to(:action => "edit"), which could throw the user to
# "/library/books/ISBN/0743536703/edit". Naturally, you'll need to setup the routes configuration file to point to the proper controller
# and action in the first place, but once you have, it can be rewritten with ease.
#
# Let's consider a bunch of examples on how to go from "/clients/37signals/basecamp/project/dash" to somewhere else:
#
# redirect_to(:action => "edit") =>
# /clients/37signals/basecamp/project/dash
#
# redirect_to(:client_name => "nextangle", :project_name => "rails") =>
# /clients/nextangle/rails/project/dash
#
# Those redirects happen under the configuration of:
#
# map.connect 'clients/:client_name/:project_name/:controller/:action'
#
# == Calling multiple redirects or renders
#
# An action should conclude with a single render or redirect. Attempting to try to do either again will result in a DoubleRenderError:
#
# def do_something
# redirect_to :action => "elsewhere"
# render :action => "overthere" # raises DoubleRenderError
# end
#
# If you need to redirect on the condition of something, then be sure to add "and return" to halt execution.
#
# def do_something
# redirect_to(:action => "elsewhere") and return if monkeys.nil?
# render :action => "overthere" # won't be called unless monkeys is nil
# end
#
# == Environments
#
# Action Controller works out of the box with CGI, FastCGI, and mod_ruby. CGI and mod_ruby controllers are triggered just the same using:
#
# WeblogController.process_cgi
#
# FastCGI controllers are triggered using:
#
# FCGI.each_cgi{ |cgi| WeblogController.process_cgi(cgi) }
