ActionView::Template::Error: Missing host to link to
I ran into this problem the other day and this is what ended up working for me:
Rails.application.routes.default_url_options[:host] = '???'
edit
This goes in each environment file - development.rb
, test.rb
and production.rb
(and more if you have them) with the corresponding host name in each one
You've to set the default_url in each environment(development, test, production).
You need make these changes.
config/environments/development.rb
config.action_mailer.default_url_options =
{ :host => 'your-host-name' } #if it is local then 'localhost:3000'
config/environments/test.rb
config.action_mailer.default_url_options =
{ :host => 'your-host-name' } #if it is local then 'localhost:3000'
config/environments/production.rb
config.action_mailer.default_url_options =
{ :host => 'your-host-name' } #if it is local then 'localhost:3000'
