Trying to call _path or _url from class in /lib (ROR) - ruby-on-rails

Question

I am trying to build a "router" for users that fires on login. I am trying to redirect users by role.
I have the following:
require "#{Rails.root}/lib/client/user_router"
class ApplicationController < ActionController::Base
# Prevent CSRF attacks by raising an exception.
# For APIs, you may want to use :null_session instead.
protect_from_forgery with: :exception
add_flash_types :info
def after_sign_in_path_for(user)
UserRouter.new(user)
end
end
and in /lib/user_router.rb
class UserRouter
include Rails.application.routes.url_helpers
def initialize(user)
#user = user
route_user_by_role
end
def route_user_by_role
if #user.is_pt_master?
pt_master_root_url
elsif #user.is_traveler?
traveler_root_url
elsif #user.client_user_role?
route_client_by_role
else
root_url
end
end
def route_client_by_role
if #user.is_super_admin?
for_super_admin
else
for_other_admin
end
end
def for_super_admin
if #user.client_account.blank?
edit_client_account_url
else
client_root_url
end
end
def for_other_admin
if #user.is_first_sign_in? || #user.client_user_info.blank?
edit_client_user_info_url(#user)
else
client_root_url
end
end
end
I am using _url because if I use _path I get a .to_model error, but with _url I am getting Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
I have already set default host in config/environments to be localhost:3000. Any help with how to do this would be greatly appreciated.

Answer 1

Add default_url_options to UserRouter:
class UserRouter
include Rails.application.routes.url_helpers
def self.default_url_options
{host: 'localhost:3000'}
end
def initialize(user)
#user = user
route_user_by_role
end
def route_user_by_role
if #user.is_pt_master?
pt_master_root_url
elsif #user.is_traveler?
traveler_root_url
elsif #user.client_user_role?
route_client_by_role <= breaks here with undefined method error
else
root_url
end
end
def route_client_by_role
if #user.is_super_admin?
for_super_admin
else
for_other_admin
end
end
def for_super_admin
if #user.client_account.blank?
edit_client_account_url
else
client_root_url
end
end
def for_other_admin
if #user.is_first_sign_in? || #user.client_user_info.blank?
edit_client_user_info_url(#user)
else
client_root_url
end
end
end

Answer 2

So I wasn't able to do it as Class in /lib/ like I wanted to, but pulling it out into a module as a Controller concern allowed me to keep the logic separate from the ApplicationController like I wanted to, its not ideal, but better than stuffing it all into App Cntrl.
class ApplicationController < ActionController::Base
include UserRouter
...
def after_sign_in_path_for(user)
initialize_user_router(user)
end
...
end
module UserRouter
def initialize_user_router(user)
#user = user
direct_user_by_role
end
def direct_user_by_role
if #user.is_pt_master?
pt_master_root_path
elsif #user.is_traveler?
direct_traveler
elsif #user.client_user_role?
direct_client_by_role
else
root_path
end
end
def direct_traveler
...
traveler_root_path
end
def direct_client_by_role
if #user.is_super_admin?
direct_super_admins
else
direct_other_admins
end
end
def direct_super_admins
if #user.client_account.blank?
edit_client_account_path
else
client_root_path
end
end
def direct_other_admins
if #user.first_sign_in? || #user.client_user_info.blank?
edit_client_user_info_path(#user)
else
client_root_path
end
end
end
