Question

There is a code in my Sinatra app

    - if flash[:error]
      .alert.alert-error
        %button.close{:type =>" button", "data-dismiss"=>"alert"}x
        = flash[:error]
    - if flash[:warning]
      .alert.alert-warning
        %button.close{:type =>" button", "data-dismiss"=>"alert"}x
        = flash[:warning]
    - if flash[:info]
      .alert.alert-info
        %button.close{:type =>" button", "data-dismiss"=>"alert"}x
        = flash[:info]

Is there any way to simply it? In particular, is there any way to get rid of repeating :type =>" button", "data-dismiss"=>"alert" hash initialisations by storing them as a variable?

Answer 1

Try something like:

- flash.each do |type, message|
  .alert{ :class => "alert-#{type}" }
    %button.close{:type =>" button", "data-dismiss"=>"alert"}x
    = message
