How to set exception_recipients after initialisation?

[bollard]

I want to be able to define the exception_recipients dynamically, based on the Rails environment. For example:

recipients = Rails.env == 'production'
   [email protected]
else
   User.current.email
end

In this way I won't spam the rest of my team while I am developing new features. but in production we can all respond to issues. However, from the docs:

Whatever::Application.config.middleware.use ExceptionNotification::Rack,
  :email => {
    :email_prefix => "[Whatever] ",
    :sender_address => %{"notifier" <[email protected]>},
    :exception_recipients => %w{[email protected]}
  }

In config/environments/production.rb where i don't have an ActiveRecord::Base connection yet.

Is this possible? Or can there be a call to default_options=(opts)?

Thanks

I'm looking for something similar:

I just want to send an email to all Users.where(admin: true).
Tried using a lambda/proc as :exception_recipients - but it seems to get not evaluated once it is needed.
Would be really great to provide a lazy-loading with procs for recipients.
