How to use rescue in rake task

I have a rake task like this:

task :update_all => :environment do
        codes = get_all_codes
        codes.each{ |code| find_or_create_from_my_data(code) }
end

Sometimes the update fails, so I want to know with which code failed. For that I wrote like this:

task :update_all => :environment do
    begin
        codes = get_all_codes
        @code
        codes.each{ |code| @code = code; find_or_create_from_my_data(code) }
    rescue
        p @code
    end
end

It works fine, but I think it's a bit redundant. How can I write more effectively?

How about this:

task :update_all => :environment do
  get_all_codes.each do |code|
    begin
      find_or_create_from_my_data(code)
    rescue
      p code
    end
  end
end

This way, even if one code fails, it will print it out and move on to the other ones instead of aborting early.

the e.message will display for you which code failed and why

task :update_all => :environment do
    codes = get_all_codes
    codes.each{ |code| find_or_create_from_my_data(code) }
  rescue => e
    puts "(#{e.message})"
end
