Getting RuntimeError: "In order to use #url_for, you must include routing helpers explicitly" when I've already included them

Question

Inside a controller I've tried to run this code for when users that are already logged in stumble across the sign up page

def index
  if current_user
    redirect_to homebase_url #should provide url to home for logged in users
  end
end

I've done what the rails error message said and have added: include Rails.application.routes.url_helpers to the containing controller class. Still getting this error though. Definitely do not want to hardcode URLs into there for legacy purposes. Thanks

Typically, you shouldn't need need to include url_helpers in a Rails controller. Two questions: (1) Are you sure the error is being thrown by the line calling redirect_to homebase_url? If it's being thrown somewhere else (such as within a template), you may have to include the url_helpers somewhere else, like the ApplicationHelper. (2) Would you be able to show a full stack trace along with more of the full controller class? — Charlie Tran

I had added the include Rails.application.routes.url_helpers to an initializer and somehow that was screwing everything up. Figured it out right after I left the bounty. I guess if anything I wouldn't mind knowing why that caused that.. — boulder_ruby

Could you post the entire controller class and the initializer, there might be an issue with including the UrlHelpers in the initializer before routes are loaded. — Jan Bussieck

Please post the full error with backtrace - it isn't coming from that line unless that line is surrounded by unusual code. — sevenseacat

Remove the include Rails.application.routes.url_helpers declaration, it's not needed unless it's in something like a helper. Routes are included in controllers by default. Including it in a model or controller/initializer (routes are loaded before initializers) is against MVC architecture and might cause unwanted behaviour.

I recommend using homebase_path instead of homebase_url

For example when looking at http://stackoverflow.com/questions/41903124/getting-runtimeerror-in-order-to-use-url-for-you-must-include-routing-helper/42048113#42048113

console.log(window.location.pathname) // => "/questions/41903124/getting-r..."
console.log(window.location.host) // => "stackoverflow.com"

path is the stuff after the domain name(host).

a complete URL(in your case homebase_url) requires both a host and a path. In development its a bit awkward to get a host because its a different value in production than it is in development.
