ActionMailer::Base.default_url_options
Hi,
I want so set a default url for ActionMailer. I know,
ActionMailer::Base.default_url_options is deprecated, so I use
config.action_mailer.default_url_options = {
:host => "localhost"
}
in my environments (test.rb, production.rb, ...). The problem is, I get a
deprecation error and rails won''t start. I have no solution...
Any hints for me?

/some/new/app cd to the directory and rails server and my worst fears

ConnectionNotEstablished when using connection on AR::Base abstract subclass
I''m using AR outside of Rails and calling establish_connection on an
ActiveRecord::Base abstract_class subclass (to protect my connection
in case anyone else is using AR). It was working just fine with AR
3.0.9, but I recently attempted to upgrade to AR 3.2.2. Now, when I
hit a "nested" query from a has_many, I get a

Yesterday everything worked, my own changes are very minor and in the

other problem (on my own system only, even if I''m
