module NoResultsHelper

  # Helper to render the /common/no_results partial custamizable content.
  # Example usage:
  # no_results_box action_url: new_project_version_path(@project),
  #                display_action: authorize_for('messages', 'new')
  #
  # All arguments are optional.
  #  - 'action_url' The url for the link in the content.
  #  - 'display_action' Whether or not the link should be displayed.
  #  - 'custom_title' custom text for the title.
  #  - 'custom_action_text' custom text for the title.
  #
  # Calling this on its on without any arguments creates the box in its simplest
  # form with only the title. Providing an action_url and display_action: true
  # Displays the box with the title and link to the passed in url.
  # The title and action_text are found using the locales key lookup unless
  # custom_title and custom_action_text are provided.
  def no_results_box(action_url:         nil,
                     display_action:     false,
                     custom_title:       nil,
                     custom_action_text: nil)

    title = custom_title || t('.no_results_title_text', cascade: true)
    action_text = custom_action_text || t('.no_results_content_text')

    render partial: '/common/no_results',
            locals: {
                      title_text:  title,
                      action_text: display_action ? action_text : '',
                      action_url:  action_url || ''
                    }
