Constructor Details

#initialize(builder, object_name, attribute_name, item, value_method:, text_method:, hint_method:, bold_labels:, link_errors: false) ⇒ CollectionRadioButton

Returns a new instance of CollectionRadioButton.

Parameters:

  • link_errors (Boolean) (defaults to: false) —

    used to control the id generated for radio buttons. The error summary requires that the id of the first radio is linked-to from the corresponding error message. As when the summary is built what happens later in the form is unknown, we need to control this to ensure the link is generated correctly
