# This helper may be included in any class that includes the

|
# URL helpers of a router (router.url_helpers). Some methods
|

# provided here will only work in the4 context of a request

# Returns the URL for the set of +options+ provided. This takes the
|
|
# same options as +url_for+ in Action Controller (see the
|
|
# documentation for <tt>ActionController::Base#url_for</tt>). 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 persisted? call (and in this case returning false)
|
|
# # => /workshops
|
|
#
|
|
# <%= url_for(@workshop) %>
|
|
# # calls @workshop.to_s
|
|
# # => /workshops/5
|
|
#
|
|
# <%= url_for("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(body, url, html_options = {})
|
|
# # url is a String; you can use URL helpers like
|
|
# # posts_path
|
|
#
|
|
# link_to(body, url_options = {}, html_options = {})
|
|
# # url_options, except :confirm or :method,
|
|
# # is passed to url_for
|
|
#
|
|
# link_to(options = {}, html_options = {}) do
|
|
# # name
|
|
# end
|
|
#
|
|
# link_to(url, html_options = {}) do
|
|
# # name
|
|
# end
|
|
#
|
|
# ==== Options
|
|
# * <tt>:confirm => 'question?'</tt> - This will allow the unobtrusive JavaScript
|
|
# driver to prompt with the question specified. If the user accepts, the link is
|
|
# processed normally, otherwise no action is taken.
|
|
# * <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 <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, 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>.
|
|
# * <tt>:remote => true</tt> - This will allow the unobtrusive JavaScript
|
|
# driver to make an Ajax request to the URL in question instead of following
|
|
# the link. The drivers each provide mechanisms for listening for the
|
|
# completion of the Ajax request and performing JavaScript operations once
|
|
# they're complete
|
|
#
|
|
# ==== 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 two options specific to +link_to+ (<tt>:confirm</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/" data-confirm="Are you sure?"">Visit Other Site</a>
|
|
#
|
|
# link_to("Destroy", "http://www.example.com", :method => :delete, :confirm => "Are you sure?")
|
|
# # => <a href='http://www.example.com' rel="nofollow" data-method="delete" data-confirm="Are you sure?">Destroy</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 as 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 use the unobtrusive JavaScript driver to
|
|
# prompt with the question specified. If the user accepts, the link is
|
|
# processed normally, otherwise no action is taken.
|
|
# * <tt>:remote</tt> - If set to true, will allow the Unobtrusive JavaScript drivers to control the
|
|
# submit behaviour. By default this behaviour is an ajax submit.
|
|
#
|
|
# ==== Examples
|
|
# <%= button_to "New", :action => "new" %>
|
|
# # => "<form method="post" action="/controller/new" class="button_to">

#
|
|
# ==== Examples
|

|
# <li><a href="/controller/index">Home</a></li>
|
|
# <li>About Us</li>

# <li><a href="/controller/about">About Us</a></li>

|
|
#
|
|
# 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.
