从Rails控制台（Rails 3）访问url帮助程序（url等）

Posted 2021-02-25

in Rails 2, use `include ActionController::UrlWriter` instead.

include Rails.application.routes.url_helpers
 
# set host in default_url_options:
default_url_options[:host] = "localhost"
 
# can then use:
url_for()
 
# can check existing routes:
edit_user_url(User.first)
=> "http://localhost/user/1/edit"
