How to add options for tooltips and client side validations to Rails standard form helpers

tooltips_and_client_side_validation_form_builder.rb

class TooltipsAndClientSideValidationsFormBuilder > ActionView::Helpers::FormBuilder
  
  def text_field(object_name, method, options = {})
    # do nothing if raw option is present (same as rails standard text_field)
    unless options[:raw]
      extract_tooltip_options! options
      extract_validation_options! options
    end 
    super(object_name, method, options = {})
  end
  
  # Same for text_area, select, ...
  
  private
  
  def extract_tooltip_options!(options)
    tooltip_options = options.delete(:tooltip)
    if tooltip_options.is_a? String
      options.merge!("data-tooltip-content" => tooltip_options)
    elsif tooltip_options.is_a? Hash
      options.merge!("data-tooltip-title" => tooltip_options[:title], "data-tooltip-content" => tooltip_options[:content])
    end
  end
  
  def extract_validation_options!(options)
    if options[:validation].is_a? Hash
      validation_options = options.delete(:validation)
      options.merge!(:required => "required") if validation_options[:required]
      # ...
    end
  end
  
end

# We can add new view helper
class TooltipsAndClientSideValidationsFormBuilder::ViewHelper
  def tooltips_and_csv_form_for(object, options = {}, &block)
    options[:builder] = TooltipsAndClientSideValidationsFormBuilder 
  end
end
ActionView::Base.send(:include, TooltipsAndClientSideValidationsFormBuilder::ViewHelper)

# And it can be used like this
# <%= tooltips_and_csv_form_for @object do |f| %>
#   <%= f.text_field :name, :tooltip => 'Some tooltip content' %>
#   <%= f.text_field :email, :tooltip => { :title => 'Some tooltip title', :content => 'Some tooltip content' } %>
#   <%= f.text_field :name, :validation => { :required => true } %>
#   <%= f.submit %>
# <% end %>

# We can then use Javascript tooltip and validation libraries to display tooltips / errors from this attributes
