label(method, text = nil, options = {}, &block) public

Returns a label tag tailored for labelling an input field for a specified attribute (identified by method) on an object assigned to the template (identified by object). The text of label will default to the attribute name unless a translation is found in the current I18n locale (through helpers.label.<modelname>.<attribute>) or you specify it explicitly. Additional options on the label tag can be passed as a hash with options. These options will be tagged onto the HTML as an HTML element attribute as in the example shown, except for the :value option, which is designed to target labels for radio_button tags (where the value is used in the ID of the input tag).

Examples

label(:post, :title)
# => <label for="post_title">Title</label>

You can localize your labels based on model and attribute names. For example you can define the following in your locale (e.g. en.yml)

helpers:
  label:
    post:
      body: "Write your entire text here"

Which then will result in

label(:post, :body)
# => <label for="post_body">Write your entire text here</label>

Localization can also be based purely on the translation of the attribute-name (if you are using ActiveRecord):

activerecord:
  attributes:
    post:
      cost: "Total cost"

label(:post, :cost)
# => <label for="post_cost">Total cost</label>

label(:post, :title, "A short title")
# => <label for="post_title">A short title</label>

label(:post, :title, "A short title", class: "title_label")
# => <label for="post_title" class="title_label">A short title</label>

label(:post, :privacy, "Public Post", value: "public")
# => <label for="post_privacy_public">Public Post</label>

label(:post, :terms) do
  'Accept <a href="/terms">Terms</a>.'.html_safe
end
