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

Adding the default_url in routes not the right solution although, it works for some cases.

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/development.rb
     config.action_mailer.default_url_options = 
      { :host => 'your-host-name' }  #if it is local then 'localhost:3000'
