Working on a rails form generator. As easy as:

<%= easy_form_for(@user) %>

or as advanced as:

<%= easy_form_for(@user,
                  :only => [:name, (:username if @user.username.blank?), :email, :birthday, :city, :state_id, :zipcode, :country_id, :bio, :diet_id, :me_gender, :you_gender],
                  :field_options => {
                    :email    => {:type => "email", :autocapitalize => "off"},
                    :submit   => {:disable_with => "Saving&hellip;".html_safe, :class => "button white full"},
                    :birthday => {
                      :order         => [:month, :day, :year],
                      :start_year    => 12.years.ago.year,
                      :end_year      => 60.years.ago.year,
                      :include_blank => true},
                    :me_gender  => {:label => "My Gender"},
                    :you_gender => {:label => "Desired Gender"}
                  }) do |f| %>
