Devise after_sign_up_for path not working - ruby-on-rails

Question

I read all the thread on this, but I still can't figure out what is wrong. I have gone through all the devise implementation guides and followed them but after a new user registration, the redirect goes to the users controller, specifically users#show.
The initial call to a new registration is going through my registrations controller. That has been verified. But after the registration it doesn't pass through the registrations controller again. It goes through the users controller. I put a break in the two overriding methods in the new registrations controller and they never hit.
/routes.rb
Rails.application.routes.draw do
root to: 'app#index'
devise_for :users, controllers: { registrations: "registrations" }
resources :users do
member do
put 'follow', to: 'users#follow'
put 'unfollow', to: 'users#unfollow'
end
end
end
registrations_controller.rb
class RegistrationsController < Devise::RegistrationsController
protected
#call for new registration does pass through here
#after new registration does not pass through here
def after_inactive_sign_up_path_for(resource)
#never gets here after new registration
other_path(resource)
end
def after_sign_up_path_for(resource)
#never gets here after new registration
other_path(resource)
end
end
new registration form:
<form action="index.html">
<%= form_for(resource, as: resource_name, url: registration_path(resource_name)) do |f| %>
<%= devise_error_messages! %>
<div class="form-group">
<%= f.email_field :email, autofocus: true, placeholder: "Email", class: "form-control rounded input-lg text-center no-border" %>
</div>
<div class="form-group">
<% if #minimum_password_length %>
<em>(<%= #minimum_password_length %> characters minimum)</em>
<% end %><br />
<%= f.password_field :password, autocomplete: "off", placeholder: "Password", class: "form-control rounded input-lg text-center no-border" %>
</div>
<div class="form-group">
<%= f.password_field :password_confirmation, autocomplete: "off", placeholder: "Confirm Password", class: "form-control rounded input-lg text-center no-border" %>
</div>
<div class="checkbox i-checks m-b">

Answer 1

If you want to go to users#show, the correct path helper should be user_path(resource), is it what you want?

Answer 2

It looks like the issue is two-fold. The registrations controller is looking for the incorrect path but it also needs a proper id. I think the solution here is to pass it user_path(#user.id) instead of having resource as an argument where you have it in new_user_path(resource).
It's attempting to query for a User that has an ID of "Index" which doesn't exist and therefore it's throwing an error. You'll want to find the id of your new user and insert that to the route so that it finds that specific User profile. I used #user as an example. You can define that variable in the code or work with whatever variable you wish. I hope that helps!
