Hi,

Below is my code, which works fine in Ruby 1.8.6 (with Rails 2.3.5),  
except that sync and flush both return NoMethod. Have thos methods  
been eliminated?

Thanks in Advance,  
Richard

equire ‘rubygems’  
require ‘active\_record’

class Account \< ActiveRecord::Base  
set\_table\_name “accounts”  
has\_many :comments  
end

class Comment \< ActiveRecord::Base  
set\_table\_name “comments”  
belongs\_to :account  
end

ActiveRecord::Base.establish\_connection(  
:adapter =\> ‘mysql’,  
:host =\> ‘localhost’,  
:database =\> ‘test’,  
:username =\> ‘root’,  
:password =\> “rlmrlm”)

mylog = Logger.new(‘mylog.txt’)

# mylog.sync = true # NoMethod

error  
ActiveRecord::Base.logger = mylog  
temp = Account.find(1)  
mylog.info(“Found a record with username: #{temp.username}” )  
mylog.info(‘About to show comments’)  
temp.comments.each do |rec|  
puts “#{temp.username} said #{rec.subject}”  
end  
#mylog.flush # NoMethod  
error

sync= and flush are instance methods on IO objects. I don’t think Logger  
has them. Do you have anything which suggests that it does/did?

Hi Brian,

I found these on  
[http://maintainablesoftware.com/articles/rails\_logging\_tips](http://maintainablesoftware.com/articles/rails_logging_tips)

I was particularly interest in some flush capability the Logger seemed  
to truncate the last logged msg.

Thanks for responding.

Best wishes,  
Richard
