You can add a custom attribute to the model: class Resource < ActiveRecord::Base attr_accessor :custom_field end Then use this field as block: = f.input :custom_field, :label => false do = check_box_tag :some_name Try to find “Wrapping Rails Form Helpers” in their documentation https://github.com/plataformatec/simple_form

HAML Syntax for the HTML5 Data Field: %div{ :data => {:id => ‘555’} } Now, I started messing around, and it looks like this only works with “data” — other tags need to be: %div{ “star-datas” => “hello!” } Your example: %body{:data => { :spy => ‘abcd’}}

You’re mixing up two distinct Rails feature: partials (using render) and layouts (using yield). You can add a rails-like version of either (or both) of them to a Haml only program. Partials In a rails view, you can use render :partial_name to cause the file _partial_name.html.haml to be rendered at that point in the containing … Read more
