Action View URL Helpers

Provides a set of methods for making links and getting URLs that depend on the routing subsystem (see ActionDispatch::Routing). This allows you to use the same format for links in views and controllers.

_current_page?(options = nil, check_parameters: false, **options_as_kwargs)

Alias for: current_page?

button_to(name = nil, options = nil, html_options = nil, &block)

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.

You can control the form and button behavior with html_options. Most values in html_options are passed through to the button element. For example, passing a :class option within html_options will set the class attribute of the button element.

The class attribute of the form element can be set by passing a :form_class option within html_options. It defaults to "button_to" to allow styling of the form and its children.

The form submits a POST request by default. You can specify a different HTTP verb via the :method option within html_options.

If the HTML button generated from button_to does not work with your layout, you can consider using the link_to method with the data-turbo-method attribute as described in the link_to documentation.

Options

The options hash accepts the same options as url_for. To generate a <form> element without an [action] attribute, pass false:

<%= button_to "New", false %>
# => "<form method="post" class="button_to">
#      <button type="submit">New</button>
#      <input name="authenticity_token" type="hidden" value="10f2163b45388899ad4d5ae948988266befcb6c3d1b2451cf657a0c293d605a6"/>
#    </form>"

Most values in html_options are passed through to the button element, but there are a few special options:

  • :method - Symbol of HTTP verb. Supported verbs are :post, :get, :delete, :patch, and :put. By default it will be :post.

  • :disabled - If set to true, it will generate a disabled button.

  • :data - This option can be used to add custom data attributes.

  • :form - This hash will be form attributes

  • :form_class - This controls the class of the form within which the submit button will be placed

  • :params - Hash of parameters to be rendered as hidden fields within the form.

Deprecated: Rails UJS Attributes

Prior to Rails 7, Rails shipped with a JavaScript library called @rails/ujs on by default. Following Rails 7, this library is no longer on by default. This library integrated with the following options:

  • :remote - If set to true, will allow @rails/ujs to control the submit behavior. By default this behavior is an Ajax submit.

@rails/ujs also integrated with the following :data options:

  • confirm: "question?" - This will allow @rails/ujs to prompt with the question specified (in this case, the resulting text would be question?). If the user accepts, the button is processed normally, otherwise no action is taken.

  • :disable_with - Value of this parameter will be used as the value for a disabled version of the submit button when the form is submitted.

Rails UJS Examples
<%= button_to "Create", { action: "create" }, remote: true, form: { "data-type" => "json" } %>
# => "<form method="post" action="/images/create" class="button_to" data-remote="true" data-type="json">

current_page?(options = nil, check_parameters: false, **options_as_kwargs)

True if the current request URI was generated by the given options.

Examples

Let’s say we’re in the http://www.example.com/shop/checkout?order=desc&page=1 action.

current_page?(action: 'process')
# => false

current_page?(action: 'checkout')
# => true

current_page?(controller: 'library', action: 'checkout')
# => false

current_page?(controller: 'shop', action: 'checkout')

# => false

current_page?('/shop/checkout')
# => true

current_page?('http://www.example.com/shop/checkout?order=desc&page=1')
# => true

Let’s say we’re in the http://www.example.com/products action with method POST in case of invalid product.

current_page?(controller: 'product', action: 'index')

🔎 See on GitHub

Creates an anchor element of the given name using a URL created by the set of options. See the valid options in the documentation for url_for. It’s also possible to pass a String instead of an options hash, which generates an anchor element that uses the value of the String as the href for the link. Using a :back Symbol instead of an options hash will generate a link to the referrer (a JavaScript back link will be used in place of a referrer if none exists). If nil is passed as the name the value of the link itself will become the name.

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 :method, is passed to url_for

link_to(options = {}, html_options = {}) do
  # name
end

link_to(url, html_options = {}) do
  # name
end

link_to(active_record_model)

  • :data - This option can be used to add custom data attributes.

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>

When name is nil the href is presented instead

link_to nil, "http://example.com"
# => <a href="http://www.example.com">http://www.example.com</a>

More concise yet, when name is an Active Record model that defines a to_s method returning a default value or a model instance attribute

link_to @profile
# => <a href="http://www.example.com/profiles/1">Eileen</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>

You can set any link attributes such as target, rel, type:

link_to "External link", "http://www.rubyonrails.org/", target: "_blank", rel: "nofollow"
# => <a href="http://www.rubyonrails.org/" target="_blank" rel="nofollow">External link</a>

Rails 7 ships with Turbo enabled by default. Turbo provides the following :data options:

  • turbo_method: symbol of HTTP verb - Performs a Turbo link visit with the given HTTP verb. Forms are recommended when performing non-GET requests. Only use data-turbo-method where a form is not possible.

  • turbo_confirm: "question?" - Adds a confirmation dialog to the link with the given value.

Consult the Turbo Handbook for more information on the options above.

link_to "Delete profile", @profile, data: { turbo_method: :delete }
# => <a href="/profiles/1" data-turbo-method="delete">Delete profile</a>

link_to "Visit Other Site", "https://rubyonrails.org/", data: { turbo_confirm: "Are you sure?" }
# => <a href="https://rubyonrails.org/" data-turbo-confirm="Are you sure?">Visit Other Site</a>

Prior to Rails 7, Rails shipped with a JavaScript library called @rails/ujs on by default. Following Rails 7, this library is no longer on by default. This library integrated with the following options:

  • method: symbol of HTTP verb - 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 :post, :delete, :patch, and :put. Note that if the user has JavaScript disabled, the request will fall back to using GET. If href: '#' 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 post?, delete?, patch?, or put?.

  • remote: true - This will allow @rails/ujs to make an Ajax request to the URL in question instead of following the link.

@rails/ujs also integrated with the following :data options:

  • confirm: "question?" - This will allow @rails/ujs to prompt with the question specified (in this case, the resulting text would be question?). If the user accepts, the link is processed normally, otherwise no action is taken.

  • :disable_with - Value of this parameter will be used as the name for a disabled version of the link.

link_to "Remove Profile", profile_path(@profile), method: :delete
# => <a href="/profiles/1" rel="nofollow" data-method="delete">Remove Profile</a>

link_to "Visit Other Site", "http://www.rubyonrails.org/", data: { confirm: "Are you sure?" }
# => <a href="http://www.rubyonrails.org/" data-confirm="Are you sure?">Visit Other Site</a>

Creates a link tag of the given name using a URL created by the set of options if condition is true, otherwise only the name is returned. To specialize the default behavior, you can pass a block that accepts the name or the full argument list for link_to_if.

Creates a link tag of the given name using a URL created by the set of options unless condition is true, in which case only the name is returned. To specialize the default behavior (i.e., show a login link rather than just the plaintext link text), you can pass a block that accepts the name or the full argument list for link_to_unless.

<%= link_to_unless(@current_user.nil?, "Reply", { action: "reply" }) %>

🔎 See on GitHub

Creates a link tag of the given name using a URL created by the set of options unless the current request URI is the same as the links, in which case only the name is returned (or the given block is yielded, if one exists). You can give link_to_unless_current a block which will specialize the default behavior (e.g., show a “Start Here” link rather than the link’s text).

Let’s say you have a navigation menu…

<ul id="navbar">
  <li><%= link_to_unless_current("Home", { action: "index" }) %></li>
  <li><%= link_to_unless_current("About Us", { action: "about" }) %></li>
</ul>

If in the “about” action, it will render…

<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…

<%=
    link_to_unless_current("Comment", { controller: "comments", action: "new" }) do
       link_to("Go back", { controller: "posts", action: "index" })
    end

mail_to(email_address, name = nil, html_options = {}, &block)

Creates a mailto link tag to the specified email_address, which is also used as the name of the link unless name is specified. Additional HTML attributes for the link can be passed in html_options.

mail_to has several methods for customizing the email itself by passing special keys to html_options.

Options

  • :subject - Preset the subject line of the email.

  • :body - Preset the body of the email.

  • :cc - Carbon Copy additional recipients on the email.

  • :bcc - Blind Carbon Copy additional recipients on the email.

  • :reply_to - Preset the Reply-To field of the email.

Obfuscation

Prior to Rails 4.0, mail_to provided options for encoding the address in order to hinder email harvesters. To take advantage of these options, install the actionview-encoded_mail_to gem.

Examples

mail_to "me@domain.com"
# => <a href="mailto:me@domain.com">me@domain.com</a>

mail_to "me@domain.com", "My email"
# => <a href="mailto:me@domain.com">My email</a>

mail_to "me@domain.com", cc: "ccaddress@domain.com",
         subject: "This is an example email"
# => <a href="mailto:me@domain.com?cc=ccaddress@domain.com&subject=This%20is%20an%20example%20email">me@domain.com</a>

You can use a block as well if your link target is hard to fit into the name parameter. ERB example:

<%= mail_to "me@domain.com" do %>
  <strong>Email me:</strong> <span>me@domain.com</span>
<% end %>
# => <a href="mailto:me@domain.com">
       <strong>Email me:</strong> <span>me@domain.com</span>

phone_to(phone_number, name = nil, html_options = {}, &block)

Creates a TEL anchor link tag to the specified phone_number. When the link is clicked, the default app to make phone calls is opened and prepopulated with the phone number.

If name is not specified, phone_number will be used as the name of the link.

A country_code option is supported, which prepends a plus sign and the given country code to the linked phone number. For example, country_code: "01" will prepend +01 to the linked phone number.

Additional HTML attributes for the link can be passed via html_options.

Options

  • :country_code - Prepends the country code to the phone number

Examples

phone_to "1234567890"
# => <a href="tel:1234567890">1234567890</a>

phone_to "1234567890", "Phone me"
# => <a href="tel:1234567890">Phone me</a>

phone_to "1234567890", country_code: "01"
# => <a href="tel:+011234567890">1234567890</a>

You can use a block as well if your link target is hard to fit into the name parameter. ERB example:

<%= phone_to "1234567890" do %>
  <strong>Phone me:</strong>
<% end %>
# => <a href="tel:1234567890">
       <strong>Phone me:</strong>
     </a>
