SimpleForm::ActionViewExtensions::Builder

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.

Examples

form_for @user do |f|
  f.collection_check_box :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_box" 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_box" for="user_options_false">No</label>

Options

Collection check box accepts some extra 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.

# File lib/simple_form/action_view_extensions/builder.rb, line 71
def collection_check_boxes(attribute, collection, value_method, text_method, options={}, html_options={})
  collection.map do |item|
    value = item.send value_method
    text  = item.send text_method

    default_html_options = default_html_options_for_collection(item, value, options, html_options)
    default_html_options[:multiple] = true

    check_box(attribute, default_html_options, value, '') <<
      label("#{attribute}_#{value}", text, :class => "collection_check_boxes")
  end.join.html_safe
end

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. Based on collection_select.

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>

Options

Collection radio accepts some extra options:

* checked  => the value that should be checked initially.

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

# File lib/simple_form/action_view_extensions/builder.rb, line 32
def collection_radio(attribute, collection, value_method, text_method, options={}, html_options={})
  collection.map do |item|
    value = item.send value_method
    text  = item.send text_method

    default_html_options = default_html_options_for_collection(item, value, options, html_options)

    radio_button(attribute, value, default_html_options) <<
      label("#{attribute}_#{value}", text, :class => "collection_radio")
  end.join.html_safe
end

Wrapper for using simple form inside a default rails form. Example:

form_for @user do |f|
  f.simple_fields_for :posts do |posts_form|
    # Here you have all simple_form methods available
    posts_form.input :title
  end
end

# File lib/simple_form/action_view_extensions/builder.rb, line 93
def simple_fields_for(*args, &block)
  options = args.extract_options!
  options[:builder] = SimpleForm::FormBuilder
  fields_for(*(args << options), &block)
end
