Change protocol to https in all rails helpers

Question

Rails 3.1+ I want my url helpers to use the https protocol without having to specify it in every helper I call. After searching around I\'ve found various ways but none work

Answer 1

In Rails 5.1.4, I have tested the following scenarios:

# in development.rb
config.action_controller.default_url_options({:protocol => 'https'})
config.action_controller.default_url_options(:protocol => 'https')
# Does not work

# in development.rb, outside config block
Rails.application.routes.default_url_options[:protocol] = 'https'
# Does not work, but works under console

# in routes.rb
Rails.application.routes.draw do
  default_url_options protocol: :https
# Does not work, but works under console

# in ApplicationController
def default_url_options(options={})
  { secure: true }
end
# Does not work

# in ApplicationController
def default_url_options
  { protocol: :https }
end
# Works in browser, but does not work under console

# in development.rb
config.action_controller.default_url_options= {:protocol => 'https'}
# Works in browser, but does not work under console
