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

The host should be specified in each environment's config file. Eg:

config/environments/development.rb

See this question and this question.
