80 # Action Controllers are the core of a web request in Rails. They are made up of one or more actions that are executed
81 # on request and then either render a template or redirect to another action. An action is defined as a public method
82 # on the controller, which will automatically be made accessible to the web-server through Rails Routes.
84 # A sample controller could look like this:
86 # class GuestBookController < ActionController::Base
88 # @entries = Entry.find(:all)
92 # Entry.create(params[:entry])
93 # redirect_to :action => "index"
97 # Actions, by default, render a template in the <tt>app/views</tt> directory corresponding to the name of the controller and action
98 # after executing code in the action. For example, the +index+ action of the GuestBookController would render the
99 # template <tt>app/views/guestbook/index.erb</tt> by default after populating the <tt>@entries</tt> instance variable.
101 # Unlike index, the sign action will not render a template. After performing its main purpose (creating a
102 # new entry in the guest book), it initiates a redirect instead. This redirect works by returning an external
103 # "302 Moved" HTTP response that takes the user to the index action.
105 # The index and sign represent the two basic action archetypes used in Action Controllers. Get-and-show and do-and-redirect.
106 # Most actions are variations of these themes.
110 # Requests are processed by the Action Controller framework by extracting the value of the "action" key in the request parameters.
111 # This value should hold the name of the action to be performed. Once the action has been identified, the remaining
112 # request parameters, the session (if one is available), and the full request with all the HTTP headers are made available to
113 # the action through instance variables. Then the action is performed.
115 # The full request object is available with the request accessor and is primarily used to query for HTTP headers. These queries
116 # are made by accessing the environment hash, like this:
119 # location = request.env["SERVER_ADDR"]
120 # render :text => "This server hosted at #{location}"
125 # All request parameters, whether they come from a GET or POST request, or from the URL, are available through the params method
126 # which returns a hash. For example, an action that was performed through <tt>/weblog/list?category=All&limit=5</tt> will include
127 # <tt>{ "category" => "All", "limit" => 5 }</tt> in params.
129 # It's also possible to construct multi-dimensional parameter hashes by specifying keys using brackets, such as:
131 # <input type="text" name="post[name]" value="david">
132 # <input type="text" name="post[address]" value="hyacintvej">
134 # A request stemming from a form holding these inputs will include <tt>{ "post" => { "name" => "david", "address" => "hyacintvej" } }</tt>.
135 # If the address input had been named "post[address][street]", the params would have included
136 # <tt>{ "post" => { "address" => { "street" => "hyacintvej" } } }</tt>. There's no limit to the depth of the nesting.
140 # Sessions allows you to store objects in between requests. This is useful for objects that are not yet ready to be persisted,
141 # 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
142 # 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
143 # they could be changed unknowingly. It's usually too much work to keep it all synchronized -- something databases already excel at.
145 # You can place objects in the session by using the <tt>session</tt> method, which accesses a hash:
147 # session[:person] = Person.authenticate(user_name, password)
149 # And retrieved again through the same hash:
151 # Hello #{session[:person]}
153 # For removing objects from the session, you can either assign a single key to +nil+:
155 # # removes :person from session
156 # session[:person] = nil
158 # or you can remove the entire session with +reset_session+.
160 # Sessions are stored by default in a browser cookie that's cryptographically signed, but unencrypted.
161 # This prevents the user from tampering with the session but also allows him to see its contents.
163 # Do not put secret information in cookie-based sessions!
165 # Other options for session storage are:
167 # * ActiveRecord::SessionStore - Sessions are stored in your database, which works better than PStore with multiple app servers and,
168 # unlike CookieStore, hides your session contents from the user. To use ActiveRecord::SessionStore, set
170 # config.action_controller.session_store = :active_record_store
172 # in your <tt>config/environment.rb</tt> and run <tt>rake db:sessions:create</tt>.
174 # * MemCacheStore - Sessions are stored as entries in your memcached cache.
175 # Set the session store type in <tt>config/environment.rb</tt>:
177 # config.action_controller.session_store = :mem_cache_store
179 # This assumes that memcached has been installed and configured properly.
180 # See the MemCacheStore docs for more information.
184 # Each action results in a response, which holds the headers and document to be sent to the user's browser. The actual response
185 # object is generated automatically through the use of renders and redirects and requires no user intervention.
189 # Action Controller sends content to the user by using one of five rendering methods. The most versatile and common is the rendering
190 # of a template. Included in the Action Pack is the Action View, which enables rendering of ERb templates. It's automatically configured.
191 # The controller passes objects to the view by assigning instance variables:
194 # @post = Post.find(params[:id])
197 # Which are then automatically available to the view:
199 # Title: <%= @post.title %>
201 # You don't have to rely on the automated rendering. Especially actions that could result in the rendering of different templates will use
202 # the manual rendering methods:
205 # @results = Search.find(params[:query])
207 # when 0 then render :action => "no_results"
208 # when 1 then render :action => "show"
209 # when 2..10 then render :action => "show_many"
213 # Read more about writing ERb and Builder templates in link:classes/ActionView/Base.html.
217 # Redirects are used to move from one action to another. For example, after a <tt>create</tt> action, which stores a blog entry to a database,
218 # we might like to show the user the new entry. Because we're following good DRY principles (Don't Repeat Yourself), we're going to reuse (and redirect to)
219 # a <tt>show</tt> action that we'll assume has already been created. The code might look like this:
222 # @entry = Entry.new(params[:entry])
224 # # The entry was saved correctly, redirect to show
225 # redirect_to :action => 'show', :id => @entry.id
227 # # things didn't go so well, do something else
231 # In this case, after saving our new entry to the database, the user is redirected to the <tt>show</tt> method which is then executed.
233 # == Calling multiple redirects or renders
235 # An action may contain only a single render or a single redirect. Attempting to try to do either again will result in a DoubleRenderError:
238 # redirect_to :action => "elsewhere"
239 # render :action => "overthere" # raises DoubleRenderError
242 # If you need to redirect on the condition of something, then be sure to add "and return" to halt execution.
245 # redirect_to(:action => "elsewhere") and return if monkeys.nil?
246 # render :action => "overthere" # won't be called if monkeys is nil

552 # * <tt>:skip_relative_url_root</tt> - If true, the url is not constructed using the +relative_url_root+
553 # of the request so the path will include the web server relative installation directory.
555 # The URL is generated from the remaining keys in the hash. A URL contains two key parts: the <base> and a query string.
556 # Routes composes a query string as the key/value pairs not included in the <base>.
558 # The default Routes setup supports a typical Rails path of "controller/action/id" where action and id are optional, with
559 # action defaulting to 'index' when not given. Here are some typical url_for statements and their corresponding URLs:
561 # url_for :controller => 'posts', :action => 'recent' # => 'proto://host.com/posts/recent'
562 # url_for :controller => 'posts', :action => 'index' # => 'proto://host.com/posts'
563 # url_for :controller => 'posts', :action => 'index', :port=>'8033' # => 'proto://host.com:8033/posts'
564 # url_for :controller => 'posts', :action => 'show', :id => 10 # => 'proto://host.com/posts/show/10'
565 # url_for :controller => 'posts', :user => 'd', :password => '123' # => 'proto://d:123@host.com/posts'
567 # When generating a new URL, missing values may be filled in from the current request's parameters. For example,
568 # <tt>url_for :action => 'some_action'</tt> will retain the current controller, as expected. This behavior extends to
569 # other parameters, including <tt>:controller</tt>, <tt>:id</tt>, and any other parameters that are placed into a Route's
572 # The URL helpers such as <tt>url_for</tt> have a limited form of memory: when generating a new URL, they can look for
573 # missing values in the current request's parameters. Routes attempts to guess when a value should and should not be
574 # taken from the defaults. There are a few simple rules on how this is performed:
576 # * If the controller name begins with a slash no defaults are used:
578 # url_for :controller => '/home'
580 # In particular, a leading slash ensures no namespace is assumed. Thus,
581 # while <tt>url_for :controller => 'users'</tt> may resolve to
582 # <tt>Admin::UsersController</tt> if the current controller lives under
583 # that module, <tt>url_for :controller => '/users'</tt> ensures you link
584 # to <tt>::UsersController</tt> no matter what.
585 # * If the controller changes, the action will default to index unless provided
587 # The final rule is applied while the URL is being generated and is best illustrated by an example. Let us consider the
588 # route given by <tt>map.connect 'people/:last/:first/:action', :action => 'bio', :controller => 'people'</tt>.
590 # Suppose that the current URL is "people/hh/david/contacts". Let's consider a few different cases of URLs which are generated
593 # * <tt>url_for :action => 'bio'</tt> -- During the generation of this URL, default values will be used for the first and
594 # last components, and the action shall change. The generated URL will be, "people/hh/david/bio".
595 # * <tt>url_for :first => 'davids-little-brother'</tt> This generates the URL 'people/hh/davids-little-brother' -- note
596 # that this URL leaves out the assumed action of 'bio'.
598 # However, you might ask why the action from the current request, 'contacts', isn't carried over into the new URL. The
599 # answer has to do with the order in which the parameters appear in the generated path. In a nutshell, since the
600 # value that appears in the slot for <tt>:first</tt> is not equal to default value for <tt>:first</tt> we stop using
601 # defaults. On its own, this rule can account for much of the typical Rails URL behavior.
603 # Although a convenience, defaults can occasionally get in your way. In some cases a default persists longer than desired.
604 # The default may be cleared by adding <tt>:name => nil</tt> to <tt>url_for</tt>'s options.
605 # This is often required when writing form helpers, since the defaults in play may vary greatly depending upon where the
606 # helper is used from. The following line will redirect to PostController's default action, regardless of the page it is
609 # url_for :controller => 'posts', :action => nil
611 # If you explicitly want to create a URL that's almost the same as the current URL, you can do so using the
612 # <tt>:overwrite_params</tt> options. Say for your posts you have different views for showing and printing them.
613 # Then, in the show view, you get the URL for the print view like this
615 # url_for :overwrite_params => { :action => 'print' }
617 # This takes the current URL as is and only exchanges the action. In contrast, <tt>url_for :action => 'print'</tt>
618 # would have slashed-off the path components after the changed action.

684 # === Rendering an action
686 # Action rendering is the most common form and the type used automatically by Action Controller when nothing else is
687 # specified. By default, actions are rendered within the current layout (if one exists).
689 # # Renders the template for the action "goal" within the current controller
690 # render :action => "goal"
692 # # Renders the template for the action "short_goal" within the current controller,
693 # # but without the current active layout
694 # render :action => "short_goal", :layout => false
696 # # Renders the template for the action "long_goal" within the current controller,
697 # # but with a custom layout
698 # render :action => "long_goal", :layout => "spectacular"
700 # === Rendering partials
702 # Partial rendering in a controller is most commonly used together with Ajax calls that only update one or a few elements on a page
703 # without reloading. Rendering of partials from the controller makes it possible to use the same partial template in
704 # both the full-page rendering (by calling it from within the template) and when sub-page updates happen (from the
705 # controller action responding to Ajax calls). By default, the current layout is not used.
707 # # Renders the same partial with a local variable.
708 # render :partial => "person", :locals => { :name => "david" }
710 # # Renders the partial, making @new_person available through
711 # # the local variable 'person'
712 # render :partial => "person", :object => @new_person
714 # # Renders a collection of the same partial by making each element
715 # # of @winners available through the local variable "person" as it
716 # # builds the complete response.
717 # render :partial => "person", :collection => @winners
719 # # Renders a collection of partials but with a custom local variable name
720 # render :partial => "admin_person", :collection => @winners, :as => :person
722 # # Renders the same collection of partials, but also renders the
723 # # person_divider partial between each person partial.
724 # render :partial => "person", :collection => @winners, :spacer_template => "person_divider"
726 # # Renders a collection of partials located in a view subfolder
727 # # outside of our current controller. In this example we will be
728 # # rendering app/views/shared/_note.r(html|xml) Inside the partial
729 # # each element of @new_notes is available as the local var "note".
730 # render :partial => "shared/note", :collection => @new_notes
732 # # Renders the partial with a status code of 500 (internal error).
733 # render :partial => "broken", :status => 500
735 # Note that the partial filename must also be a valid Ruby variable name,
736 # so e.g. 2005 and register-user are invalid.
739 # == Automatic etagging
741 # Rendering will automatically insert the etag header on 200 OK responses. The etag is calculated using MD5 of the
742 # response body. If a request comes in that has a matching etag, the response will be changed to a 304 Not Modified
743 # and the response body will be set to an empty string. No etag header will be inserted if it's already set.
745 # === Rendering a template
747 # Template rendering works just like action rendering except that it takes a path relative to the template root.
748 # The current layout is automatically applied.
750 # # Renders the template located in [TEMPLATE_ROOT]/weblog/show.r(html|xml) (in Rails, app/views/weblog/show.erb)
751 # render :template => "weblog/show"
753 # # Renders the template with a local variable
754 # render :template => "weblog/show", :locals => {:customer => Customer.new}
756 # === Rendering a file
758 # File rendering works just like action rendering except that it takes a filesystem path. By default, the path
759 # is assumed to be absolute, and the current layout is not applied.
761 # # Renders the template located at the absolute filesystem path
762 # render :file => "/path/to/some/template.erb"
763 # render :file => "c:/path/to/some/template.erb"
765 # # Renders a template within the current layout, and with a 404 status code
766 # render :file => "/path/to/some/template.erb", :layout => true, :status => 404
767 # render :file => "c:/path/to/some/template.erb", :layout => true, :status => 404
771 # Rendering of text is usually used for tests or for rendering prepared content, such as a cache. By default, text
772 # rendering is not done within the active layout.
774 # # Renders the clear text "hello world" with status code 200
775 # render :text => "hello world!"
777 # # Renders the clear text "Explosion!" with status code 500
778 # render :text => "Explosion!", :status => 500
780 # # Renders the clear text "Hi there!" within the current active layout (if one exists)
781 # render :text => "Hi there!", :layout => true
783 # # Renders the clear text "Hi there!" within the layout
784 # # placed in "app/views/layouts/special.r(html|xml)"
785 # render :text => "Hi there!", :layout => "special"
787 # === Streaming data and/or controlling the page generation
789 # The <tt>:text</tt> option can also accept a Proc object, which can be used to:
791 # 1. stream on-the-fly generated data to the browser. Note that you should
792 # use the methods provided by ActionController::Steaming instead if you
793 # want to stream a buffer or a file.
794 # 2. manually control the page generation. This should generally be avoided,
795 # as it violates the separation between code and content, and because almost
796 # everything that can be done with this method can also be done more cleanly
797 # using one of the other rendering methods, most notably templates.
799 # Two arguments are passed to the proc, a <tt>response</tt> object and an
800 # <tt>output</tt> object. The response object is equivalent to the return
801 # value of the ActionController::Base#response method, and can be used to
802 # control various things in the HTTP response, such as setting the
803 # Content-Type header. The output object is an writable <tt>IO</tt>-like
804 # object, so one can call <tt>write</tt> and <tt>flush</tt> on it.
806 # The following example demonstrates how one can stream a large amount of
807 # on-the-fly generated data to the browser:
809 # # Streams about 180 MB of generated data to the browser.
810 # render :text => proc { |response, output|
811 # 10_000_000.times do |i|
812 # output.write("This is line #{i}\n")
819 # # Renders "Hello from code!"
820 # render :text => proc { |response, output| output.write("Hello from code!") }
824 # Rendering XML sets the content type to application/xml.
826 # # Renders '<name>David</name>'
827 # render :xml => {:name => "David"}.to_xml
829 # It's not necessary to call <tt>to_xml</tt> on the object you want to render, since <tt>render</tt> will
830 # automatically do that for you:
832 # # Also renders '<name>David</name>'
833 # render :xml => {:name => "David"}
837 # Rendering JSON sets the content type to application/json and optionally wraps the JSON in a callback. It is expected
838 # that the response will be parsed (or eval'd) for use as a data structure.
840 # # Renders '{"name": "David"}'
841 # render :json => {:name => "David"}.to_json
843 # It's not necessary to call <tt>to_json</tt> on the object you want to render, since <tt>render</tt> will
844 # automatically do that for you:
846 # # Also renders '{"name": "David"}'
847 # render :json => {:name => "David"}
849 # Sometimes the result isn't handled directly by a script (such as when the request comes from a SCRIPT tag),
850 # so the <tt>:callback</tt> option is provided for these cases.
852 # # Renders 'show({"name": "David"})'
853 # render :json => {:name => "David"}.to_json, :callback => 'show'
855 # === Rendering an inline template
857 # Rendering of an inline template works as a cross between text and action rendering where the source for the template
858 # is supplied inline, like text, but its interpreted with ERb or Builder, like action. By default, ERb is used for rendering
859 # and the current layout is not used.
861 # # Renders "hello, hello, hello, again"
862 # render :inline => "<%= 'hello, ' * 3 + 'again' %>"
864 # # Renders "<p>Good seeing you!</p>" using Builder
865 # render :inline => "xml.p { 'Good seeing you!' }", :type => :builder
867 # # Renders "hello david"
868 # render :inline => "<%= 'hello ' + name %>", :locals => { :name => "david" }
870 # === Rendering inline JavaScriptGenerator page updates
872 # In addition to rendering JavaScriptGenerator page updates with Ajax in RJS templates (see ActionView::Base for details),
873 # you can also pass the <tt>:update</tt> parameter to +render+, along with a block, to render page updates inline.
875 # render :update do |page|
876 # page.replace_html 'user_list', :partial => 'user', :collection => @users
877 # page.visual_effect :highlight, 'user_list'
880 # === Rendering vanilla JavaScript
882 # In addition to using RJS with render :update, you can also just render vanilla JavaScript with :js.
884 # # Renders "alert('hello')" and sets the mime type to text/javascript
885 # render :js => "alert('hello')"
887 # === Rendering with status and location headers
888 # All renders take the <tt>:status</tt> and <tt>:location</tt> options and turn them into headers. They can even be used together:
890 # render :xml => post.to_xml, :status => :created, :location => post_url(post)
