Disable Protected Attributes In ActiveRecordHelper Forms

To make the form method in ActiveRecordHelper disable protected attribute, place the following in your application_help.rb:


def attr_protected?(record, column)
  o = instance_variable_get("@#{record}")
  o && o.class.protected_attributes &&
      o.class.protected_attributes.include?(column.name.to_sym)
end

def default_input_block
  Proc.new { |record, column|
    options = attr_protected?(record, column) ? {:disabled => true} : {}
    <<-"end_html" 
      

        #{column.human_name}
        

        #{input(record, column.name, options)}
      
    end_html
  }
end


And mark some attributes protected, for example:


class Item < ActiveRecord::Base
  attr_protected :created_at
end


The created_at attribute will be rendered but won't be editable.  This will work for "dynamic scaffolds" too!
