module ActionView
|
|
module Helpers #:nodoc:
|
|
# Provides a set of methods for making links and getting URLs that
|
|
# depend on the routing subsystem (see ActionController::Routing).
|
|
# This allows you to use the same format for links in views
|
|
# and controllers.
|
|
module UrlHelper
|
|
include JavaScriptHelper
|
|
|
|
# Returns the URL for the set of +options+ provided. This takes the
|
|
# same options as +url_for+ in Action Controller (see the
|
|
# documentation for ActionController::Base#url_for). Note that by default
|
|
# <tt>:only_path</tt> is <tt>true</tt> so you'll get the relative /controller/action
|
|
# instead of the fully qualified URL like http://example.com/controller/action.
|
|
#
|
|
# When called from a view, url_for returns an HTML escaped url. If you
|
|
# need an unescaped url, pass <tt>:escape => false</tt> in the +options+.
|
|
#
|
|
# ==== Options
|
|
# * <tt>:anchor</tt> - Specifies the anchor name to be appended to the path.
|
|
# * <tt>:only_path</tt> - If true, returns the relative URL (omitting the protocol, host name, and port) (<tt>true</tt> by default unless <tt>:host</tt> is specified).
|
|
# * <tt>:trailing_slash</tt> - If true, adds a trailing slash, as in "/archive/2005/". Note that this
|
|
# is currently not recommended since it breaks caching.
|
|
# * <tt>:host</tt> - Overrides the default (current) host if provided.
|
|
# * <tt>:protocol</tt> - Overrides the default (current) protocol if provided.
|
|
# * <tt>:user</tt> - Inline HTTP authentication (only plucked out if <tt>:password</tt> is also present).
|
|
# * <tt>:password</tt> - Inline HTTP authentication (only plucked out if <tt>:user</tt> is also present).
|
|
# * <tt>:escape</tt> - Determines whether the returned URL will be HTML escaped or not (<tt>true</tt> by default).
|
|
#
|
|
# ==== Relying on named routes
|
|
#
|
|
# If you instead of a hash pass a record (like an Active Record or Active Resource) as the options parameter,
|
|
# you'll trigger the named route for that record. The lookup will happen on the name of the class. So passing
|
|
# a Workshop object will attempt to use the workshop_path route. If you have a nested route, such as
|
|
# admin_workshop_path you'll have to call that explicitly (it's impossible for url_for to guess that route).
|
|
#
|
|
# ==== Examples
|
|
# <%= url_for(:action => 'index') %>
|
|
# # => /blog/
|
|
#
|
|
# <%= url_for(:action => 'find', :controller => 'books') %>
|
|
# # => /books/find
|
|
#
|
|
# <%= url_for(:action => 'login', :controller => 'members', :only_path => false, :protocol => 'https') %>
|
|
# # => https://www.railsapplication.com/members/login/
|
|
#
|
|
# <%= url_for(:action => 'play', :anchor => 'player') %>
|
|
# # => /messages/play/#player
|
|
#
|
|
# <%= url_for(:action => 'checkout', :anchor => 'tax&ship') %>
|
|
# # => /testing/jump/#tax&ship
|
|
#
|
|
# <%= url_for(:action => 'checkout', :anchor => 'tax&ship', :escape => false) %>
|
|
# # => /testing/jump/#tax&ship
|
|
#
|
|
# <%= url_for(Workshop.new) %>
|
|
# # relies on Workshop answering a new_record? call (and in this case returning true)
|
|
# # => /workshops
|
|
#
|
|
# <%= url_for(@workshop) %>
|
|
# # calls @workshop.to_s
|
|
# # => /workshops/5
|
|
#
|
|
# <%= url_for("http://www.example.com") %>
|
|
# # => http://www.example.com
|
|
#
|
|
# <%= url_for(:back) %>
|
|
# # if request.env["HTTP_REFERER"] is set to "http://www.example.com"
|
|
# # => http://www.example.com
|
|
#

# Creates a link tag of the given +name+ using a URL created by the set

|
# href for the link, or use <tt>:back</tt> to link to the referrer - a JavaScript back

|
# ==== Signatures
|
|
#
|
|
# link_to(name, options = {}, html_options = nil)
|
|
# link_to(options = {}, html_options = nil) do
|
|
# # name
|
|
# end
|
|
#
|
|
# ==== Options
|
|
# * <tt>:confirm => 'question?'</tt> - This will add a JavaScript confirm
|
|
# prompt with the question specified. If the user accepts, the link is
|
|
# processed normally, otherwise no action is taken.
|
|
# * <tt>:popup => true || array of window options</tt> - This will force the
|
|
# link to open in a popup window. By passing true, a default browser window
|
|
# will be opened with the URL. You can also specify an array of options
|
|
# that are passed-thru to JavaScripts window.open method.
|
|
# * <tt>:method => symbol of HTTP verb</tt> - This modifier will dynamically
|
|
# create an HTML form and immediately submit the form for processing using
|
|
# the HTTP verb specified. Useful for having links perform a POST operation
|
|
# in dangerous actions like deleting a record (which search bots can follow
|
|
# while spidering your site). Supported verbs are <tt>:post</tt>, <tt>:delete</tt> and <tt>:put</tt>.
|
|
# Note that if the user has JavaScript disabled, the request will fall back
|
|
# to using GET. If you are relying on the POST behavior, you should check
|
|
# for it in your controller's action by using the request object's methods
|
|
# for <tt>post?</tt>, <tt>delete?</tt> or <tt>put?</tt>.
|
|
# * The +html_options+ will accept a hash of html attributes for the link tag.
|
|
#
|
|
# Note that if the user has JavaScript disabled, the request will fall back
|
|
# to using GET. If <tt>:href => '#'</tt> is used and the user has JavaScript disabled
|
|
# clicking the link will have no effect. If you are relying on the POST
|
|
# behavior, your should check for it in your controller's action by using the
|
|
# request object's methods for <tt>post?</tt>, <tt>delete?</tt> or <tt>put?</tt>.
|
|
#
|
|
# You can mix and match the +html_options+ with the exception of
|
|
# <tt>:popup</tt> and <tt>:method</tt> which will raise an ActionView::ActionViewError
|
|
# exception.
|
|
#
|
|
# ==== Examples
|
|
# Because it relies on +url_for+, +link_to+ supports both older-style controller/action/id arguments
|
|
# and newer RESTful routes. Current Rails style favors RESTful routes whenever possible, so base
|
|
# your application on resources and use
|
|
#
|
|
# link_to "Profile", profile_path(@profile)
|
|
# # => <a href="/profiles/1">Profile</a>
|
|
#
|
|
# or the even pithier
|
|
#
|
|
# link_to "Profile", @profile
|
|
# # => <a href="/profiles/1">Profile</a>
|
|
#
|
|
# in place of the older more verbose, non-resource-oriented
|
|
#
|
|
# link_to "Profile", :controller => "profiles", :action => "show", :id => @profile
|
|
# # => <a href="/profiles/show/1">Profile</a>
|
|
#
|
|
# Similarly,
|
|
#
|
|
# link_to "Profiles", profiles_path
|
|
# # => <a href="/profiles">Profiles</a>
|
|
#
|
|
# is better than
|
|
#
|
|
# link_to "Profiles", :controller => "profiles"
|
|
# # => <a href="/profiles">Profiles</a>
|
|
#
|
|
# You can use a block as well if your link target is hard to fit into the name parameter. ERb example:
|
|
#
|
|
# <% link_to(@profile) do %>
|
|
# <strong><%= @profile.name %></strong> -- <span>Check it out!!</span>
|
|
# <% end %>
|
|
# # => <a href="/profiles/1"><strong>David</strong> -- <span>Check it out!!</span></a>
|
|
#
|
|
# Classes and ids for CSS are easy to produce:
|
|
#
|
|
# link_to "Articles", articles_path, :id => "news", :class => "article"
|
|
# # => <a href="/articles" class="article" id="news">Articles</a>
|
|
#
|
|
# Be careful when using the older argument style, as an extra literal hash is needed:
|
|
#
|
|
# link_to "Articles", { :controller => "articles" }, :id => "news", :class => "article"
|
|
# # => <a href="/articles" class="article" id="news">Articles</a>
|
|
#
|
|
# Leaving the hash off gives the wrong link:
|
|
#
|
|
# link_to "WRONG!", :controller => "articles", :id => "news", :class => "article"
|
|
# # => <a href="/articles/index/news?class=article">WRONG!</a>
|
|
#
|
|
# +link_to+ can also produce links with anchors or query strings:
|
|
#
|
|
# link_to "Comment wall", profile_path(@profile, :anchor => "wall")
|
|
# # => <a href="/profiles/1#wall">Comment wall</a>
|
|
#
|
|
# link_to "Ruby on Rails search", :controller => "searches", :query => "ruby on rails"
|
|
# # => <a href="/searches?query=ruby+on+rails">Ruby on Rails search</a>
|
|
#
|
|
# link_to "Nonsense search", searches_path(:foo => "bar", :baz => "quux")
|
|
# # => <a href="/searches?foo=bar&baz=quux">Nonsense search</a>
|
|
#
|
|
# The three options specific to +link_to+ (<tt>:confirm</tt>, <tt>:popup</tt>, and <tt>:method</tt>) are used as follows:
|
|
#
|
|
# link_to "Visit Other Site", "http://www.rubyonrails.org/", :confirm => "Are you sure?"
|
|
# # => <a href="http://www.rubyonrails.org/" onclick="return confirm('Are you sure?');">Visit Other Site</a>
|
|
#
|
|
# link_to "Help", { :action => "help" }, :popup => true
|
|
# # => <a href="/testing/help/" onclick="window.open(this.href);return false;">Help</a>
|
|
#
|
|
# link_to "View Image", @image, :popup => ['new_window_name', 'height=300,width=600']
|
|
# # => <a href="/images/9" onclick="window.open(this.href,'new_window_name','height=300,width=600');return false;">View Image</a>
|
|
#
|
|
# link_to "Delete Image", @image, :confirm => "Are you sure?", :method => :delete
|
|
# # => <a href="/images/9" onclick="if (confirm('Are you sure?')) { var f = document.createElement('form');
|
|
# f.style.display = 'none'; this.parentNode.appendChild(f); f.method = 'POST'; f.action = this.href;
|
|
# var m = document.createElement('input'); m.setAttribute('type', 'hidden'); m.setAttribute('name', '_method');
|
|
# m.setAttribute('value', 'delete'); f.appendChild(m);f.submit(); };return false;">Delete Image</a>

# Generates a form containing a single button that submits to the URL created
|
|
# by the set of +options+. This is the safest method to ensure links that
|
|
# cause changes to your data are not triggered by search bots or accelerators.
|
|
# If the HTML button does not work with your layout, you can also consider
|
|
# using the link_to method with the <tt>:method</tt> modifier as described in
|
|
# the link_to documentation.
|
|
#
|
|
# The generated FORM element has a class name of <tt>button-to</tt>
|
|
# to allow styling of the form itself and its children. You can control
|
|
# the form submission and input element behavior using +html_options+.
|
|
# This method accepts the <tt>:method</tt> and <tt>:confirm</tt> modifiers
|
|
# described in the link_to documentation. If no <tt>:method</tt> modifier
|
|
# is given, it will default to performing a POST operation. You can also
|
|
# disable the button by passing <tt>:disabled => true</tt> in +html_options+.
|
|
# If you are using RESTful routes, you can pass the <tt>:method</tt>
|
|
# to change the HTTP verb used to submit the form.
|
|
#
|
|
# ==== Options
|
|
# The +options+ hash accepts the same options at url_for.
|
|
#
|
|
# There are a few special +html_options+:
|
|
# * <tt>:method</tt> - Specifies the anchor name to be appended to the path.
|
|
# * <tt>:disabled</tt> - Specifies the anchor name to be appended to the path.
|
|
# * <tt>:confirm</tt> - This will add a JavaScript confirm
|
|
# prompt with the question specified. If the user accepts, the link is
|
|
# processed normally, otherwise no action is taken.
|
|
#
|
|
# ==== Examples
|
|
# <%= button_to "New", :action => "new" %>
|
|
# # => "<form method="post" action="/controller/new" class="button-to">
|
|
# # <div><input value="New" type="submit" /></div>

|
|
# specialize the default behavior (e.g., show a "Start Here" link rather
|
|
# than the link's text).
|
|
#
|
|
# ==== Examples
|
|
# Let's say you have a navigation menu...
|
|
#
|
|
# <ul id="navbar">
|
|
# <li><%= link_to_unless_current("Home", { :action => "index" }) %></li>

#

|
# <ul id="navbar">
|
|
# <li><a href="/controller/index">Home</a></li>
|
|
# <li>About Us</li>
|
|
# </ul>
|
|
#
|
|
# ...but if in the "index" action, it will render:
|
|
#
|

# <ul id="navbar">
|
|
# <li>Home</li>
|
|
# <li><a href="/controller/about">About Us</a></li>

# </ul>
|
|
#
|
|
# The implicit block given to link_to_unless_current is evaluated if the current
|
|
# action is the action given. So, if we had a comments page and wanted to render a
|
|
# "Go Back" link instead of a link to the comments page, we could do something like this...
|
|
#
|
|
# <%=

|
|
# mail_to has several methods for hindering email harvesters and customizing
|
|
# the email itself by passing special keys to +html_options+.
|
|
#
|
|
# ==== Options
|
|
# * <tt>:encode</tt> - This key will accept the strings "javascript" or "hex".
|
|
# Passing "javascript" will dynamically create and encode the mailto: link then
|
|
# eval it into the DOM of the page. This method will not show the link on
|
|
# the page if the user has JavaScript disabled. Passing "hex" will hex
|
|
# encode the +email_address+ before outputting the mailto: link.
|
|
# * <tt>:replace_at</tt> - When the link +name+ isn't provided, the
|
|
# +email_address+ is used for the link label. You can use this option to
|
|
# obfuscate the +email_address+ by substituting the @ sign with the string
|
|
# given as the value.
|
|
# * <tt>:replace_dot</tt> - When the link +name+ isn't provided, the
|
|
# +email_address+ is used for the link label. You can use this option to
|
|
# obfuscate the +email_address+ by substituting the . in the email with the
|
|
# string given as the value.
|
|
# * <tt>:subject</tt> - Preset the subject line of the email.
|
|
# * <tt>:body</tt> - Preset the body of the email.
|
|
# * <tt>:cc</tt> - Carbon Copy addition recipients on the email.
|
|
# * <tt>:bcc</tt> - Blind Carbon Copy additional recipients on the email.
