# Rails URL helpers
## Using URL helpers outside views
Instead of building the URL yourself, you can rely on the URL helpers which will always be based on your current routes:
```ruby
class RequestUserCallBackJob < ApplicationJob
include Rails.application.routes.url_helpers
def perform(user)
Net::HTTP.post(
"http://userinfoapi.com/",
body: {callback_to: user_url(user, host: "myapp.com")})
end
end
```
