• Ruby 1.9.3

• JRuby

gem install formula

<% formula_form_for @user do |f| %>
  <%= f.input :email %>
  <%= f.input :password %>
  <%= f.button 'Save' %>
<% end %>

<% formula_form_for @user do |f| %>
  <%= f.input :email, label: "Email:", hint: "We promise never to bother you." %>
  <%= f.input :password, label: "Password:", hint: "Must be at least six characters." %>
  <%= f.button 'Save' %>
<% end %>

<% formula_form_for @company do |f|
  <%= f.input :url,   container: { class: 'third' }, input: { class: 'fill' } %>
  <%= f.input :phone, container: { class: 'third' }, input: { class: 'fill' } %>
  <%= f.input :email, container: { class: 'third' }, input: { class: 'fill' } %>
