Rails: Missing host to link to! Please provide :host parameter or set default_url_options[:host]

Question

I have been googling for about 90 minutes now and still don\'t have an answer to this. Where do I set default_url_options? I\'ve already set it for conf

Answer 1

You need to add the following line at every environment:

config.action_mailer.default_url_options = { :host => "yourhost" }

That way, it can work in all environments and could be different from environment to environment. For example:

development.rb

config.action_mailer.default_url_options = { :host => "dev.yourhost.com" }

test.rb

config.action_mailer.default_url_options = { :host => "test.yourhost.com" }

production.rb

config.action_mailer.default_url_options = { :host => "www.yourhost.com" }
