  method = @opts[:method] || 'default'
  respond_to?(method) ? send(method) : "Error DcPiece: Method #{method} doesn't exist!"
end

#script ⇒ Object

Script renderer method expects rails erb code (view) in the script field. Used for designs with common code which can be shared and one part which is different. It’s functionality can be replaced with dc_replace_in_design method with ‘piece’ option specified.

Example: As used in design. Backslashing < and % is important <% <% part = “<div class=‘some-class’><%= dc_render(:my_renderer, method: ‘render_method’) %></div>” %> <%= dc_render(:dc_piece, id: ‘common’, method: ‘script’, replace: ‘[main]’, with: part) %>

Want to replace more than one part. Use array. <%= dc_render(:dc_piece, id: ‘common’, method: ‘script’, replace: [‘[part1]‘,’’], with: [part1, part2]) %>
