Question

Some confusion here. Using devise:invitable, and sending emails from heroku with the sendgrid add on.

On local, in the email that’s generated when a user is invited, <%= root_url %> generates http://localhost:3000/ – which seems perfectly correct –
but when deployed to heroku, when I receive the invite email, that same <%= root_url %> is coming out as http://yourhost.com/ …why? Where’s that set?

I thought root_url worked off routes.rb automatically and I have

root :to => 'home#splash'

I feel like I’m missing something obvious? I added the suggestions from this question to the application controller, but it has made no difference, the email still references http://yourhost.com/

Help appreciated thank you.

In your config/environments/production.rb set

config.action_mailer.default_url_options = {:host => 'www.yourdomain.com'}

You probably followed the Devise setup instructions displayed after you installed Devise which gets you to add

config.action_mailer.default_url_options = { :host => 'localhost:3000' }

to your developments.rb file – but you just forgot about production.
