What are URL helpers in model Rails?
URL helpers are used in the context of a web request, i.e. within a view or controller. In these cases the host or domain of the request is provided automatically by the application. Outside of this context you'll need to ensure you specify a host for any helpers ending in _url .
How to check routes in Rails?
TIP: If you ever want to list all the routes of your application you can use rails routes on your terminal and if you want to list routes of a specific resource, you can use rails routes | grep hotel . This will list all the routes of Hotel.
What is the difference between helpers and concerns in Rails?
Simply put: Helpers contain methods to be used in views. Concerns are modules to be included in controllers/models(depending which concern is it) etc. It's just a folder with code that you could otherwise put in another place if you wanted.
