error

nameerror: undefined local variable or method `logger' #<giveawayeligiblemembertest:0x10477dff8>     /users/kamilski81/sites/pe/vitality_mall/vendor/rails/actionpack/lib/action_controller/test_process.rb:471:in `method_missing'     /users/kamilski81/sites/pe/vitality_mall/lib/update_giveaway_eligible_members.rb:17:in `is_valid_checksum?'     /users/kamilski81/sites/pe/vitality_mall/test/unit/giveaway_eligible_member_test.rb:26:in `test_that_checksum_is_valid'     /users/kamilski81/sites/pe/vitality_mall/vendor/rails/activesupport/lib/active_support/testing/setup_and_teardown.rb:60:in `__send__'     /users/kamilski81/sites/pe/vitality_mall/vendor/rails/activesupport/lib/active_support/testing/setup_and_teardown.rb:60:in `run' 

i tried putting:

class test::unit::testcase   rails_default_logger = logger.new(stdout)   rails_default_logger.level = logger::warn    logger = logger.new(stdout)   logger.level = logger::warn end 

here code using logger:

def is_valid_checksum?(csv_arr)   expected_row_count = csv_arr[0][3].to_i   logger.debug "expected record count: #{expected_row_count}"   actual_row_count = csv_arr.nitems - 1   logger.debug "actual record count: #{actual_row_count}"   checksum_valid = false   if expected_row_count == actual_row_count     logger.debug "checksum valid"     checksum_valid = true   end    return checksum_valid end 

but still not solve error

you can use rails logger outside of models , controllers:

rails.logger.info "..."
