When I use script/runner and get an exception, the stack that is printed  
often has something like:

```
    from

```

/usr/local/lib/ruby/gems/1.8/gems/activerecord-2.3.2/lib/active\_record/transactions.rb:200:in  
`save!’  
… 9 levels…  
from  
/usr/local/lib/ruby/gems/1.8/gems/rails-2.3.2/lib/commands/runner.rb:46

Is there any way I can get a full stack?

Thanks,  
Perry

That didn’t seem to affect scripts/runner

For now, I kludged it by doing:

begin  
  
rescue =\> e  
puts e.backtrace  
exit 1  
end

I hope there is a better solution.

Thanks again,

Look for the file config/initializers/backtrace\_sileners.rb

And leave it just like this:

# Be sure to restart your server when you modify this file.

# You can add backtrace silencers for libraries that you’re using but

don’t wish to see in your backtraces.

# Rails.backtrace\_cleaner.add\_silencer { |line| line =~

/my\_noisy\_library/ }

# You can also remove all the silencers if you’re trying do debug a

problem that might steem from framework code.  
Rails.backtrace\_cleaner.remove\_silencers!

You’ll get all backtraces again.
