At the end of config/development.rb I have:

config.after\_initialize do  
ExceptionNotifier.exception\_recipients = [‘removed\_email\_address@domain.invalid’]  
FOOBAR = ‘123’ # Just for testing  
end

Now, when I run script/console (or the web server) it seems that the  
after\_inialize block doesn’t run:

Loading development environment.

> > ExceptionNotifier.exception\_recipients  
> > =\> nil
> 
> > FOOBAR  
> > =\> NameError: uninitialized constant FOOBAR

I’m on Rails 1.2.5, BTW.

What am I missing?

Thanks,

Brian

Okay so the constant thing seems to be a namespace issue. The following  
works:

config.after\_initialize do  
Kernel.const\_set(‘FOOBAR’, ‘123’)  
end

> > FOOBAR  
> > =\> ‘123’

However,

config.after\_initialize do  
ExceptionNotifier.exception\_recipients = [‘removed\_email\_address@domain.invalid’]  
puts “Recipients are #{ExceptionNotifier.exception\_recipients}”  
end

When I run script\console, I see:

Loading development environment.  
Recipients are removed\_email\_address@domain.invalid

Ack. Problem was my fault. I had conflicting code in environment.rb.
