Instance Method Details

#collection_check_boxes(attribute, collection, value_method, text_method, options = {}, html_options = {}) ⇒ Object

Creates a collection of check boxes for each item in the collection, associated with a clickable label. Use value_method and text_method to convert items in the collection for use as text/value in check boxes. You can give a symbol or a proc to both value_method and text_method, that will be evaluated for each item in the collection.

Examples

form_for @user do |f|
  f.collection_check_boxes :options, [[true, 'Yes'] ,[false, 'No']], :first, :last
end

<input name="user[options][]" type="hidden" value="" />
<input id="user_options_true" name="user[options][]" type="checkbox" value="true" />
<label class="collection_check_boxes" for="user_options_true">Yes</label>
<input name="user[options][]" type="hidden" value="" />
<input id="user_options_false" name="user[options][]" type="checkbox" value="false" />
<label class="collection_check_boxes" for="user_options_false">No</label>

Options

* checked  => the value or values that should be checked initially. Accepts
              a single item or an array of items.

* disabled => the value or values that should be disabled. Accepts a single
              item or an array of items.

  render_collection(
    attribute, collection, value_method, text_method, options, html_options
  ) do |value, text, default_html_options|
    default_html_options[:multiple] = true

  end
end

#collection_radio(attribute, collection, value_method, text_method, options = {}, html_options = {}) ⇒ Object

Create a collection of radio inputs for the attribute. Basically this helper will create a radio input associated with a label for each text/value option in the collection, using value_method and text_method to convert these text/value. You can give a symbol or a proc to both value_method and text_method, that will be evaluated for each item in the collection.

Examples

form_for @user do |f|
  f.collection_radio :options, [[true, 'Yes'] ,[false, 'No']], :first, :last
end

<input id="user_options_true" name="user[options]" type="radio" value="true" />
<label class="collection_radio" for="user_options_true">Yes</label>
<input id="user_options_false" name="user[options]" type="radio" value="false" />
<label class="collection_radio" for="user_options_false">No</label>
