a couple of Object hacks in my .irbrc

.irbrc

class Object
  def dbpeek
    ActiveRecord::Base.connection.tables
  end

  def tblpeek(tbl=nil)
    ActiveRecord::Base.connection.columns(tbl).each do |c|
      puts "#{c.name}|#{c.type}|#{c.limit}"
    end if tbl
    nil
  end

  def dbschema
    begin
            ActiveRecord::Base.connection.select_value("select version from schema_info")
    rescue
            ActiveRecord::Base.connection.select_value("select version from schema_migrations")
    end
  end

  def ml(*m)
    result = []
    m.each do |t|
      result << methods.grep(/#{t}/)
    end
    result.flatten.uniq
  end
end
