Have a bit of a conundrum that I need to solve

I would like to put this into environment.rb…

config.action\_mailer.default\_url\_options = { :host =\>  
Setting[:website\_url] }

but it obviously can’t read from the database before it is initialized  
and the configuration for action\_mailer ‘options’ apparently goes into  
environment.rb

Is there someplace I can put this so that it loads after Rails is  
started?

application\_controller.rb but in this form…

ActionMailer::Base.default\_url\_options[:host] = “[example.com](http://example.com)”

Um, perhaps in the directory mentioned in your subject line? Files in  
config/initializers will be loaded after the Rails stack has been  
initialized.

indeed… putting it into /config/initializers/mailer.rb instead  
of /config/environment.rb allowed it to work.

Thanks
