undefined method `user_url' for Devise SessionsController:create - ruby-on-rails

Question

I have user model for authorization with devise gem. I want to add after_sign_in_path method:
# application_controller.rb
protected
# redirecting to appropriate url based on role
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
end
end
Whenever I try to sign in I get this error:
undefined method `user_url' for #<Devise::SessionsController:0x007fb89b5b00a8> Did you mean? course_url
I don't know why it says 'did you mean? course_url. But I have course model. And here are my routes:
authenticate :user do
resources :feeds, only: [:index]
resources :courses, only: [:index, :show]
# etc...
end
Also here is the code it points me:
if options.empty?
recipient.send(method, *args)
else
recipient.send(method, *args, options)
end
and first line of log:
actionpack (4.2.4) lib/action_dispatch/routing/polymorphic_routes.rb:220:in `polymorphic_method'
Whenever I commend after_sign_in_path_for I am able to sign in. If I comment contents of after_sign_in_path_for but leave empty after_sign_in_path_for method, I also get this error.
EDIT: I tested that I am not also signed in, not just not redirected. I think error happens right in the call after_sign_in_path_for, not in the redirect_to or whatever. Probably it has to do something with resource.

I had the same issue (Rails 7). I fixed it this way:
Add :turbo_stream as a navigational format. This line goes in config/initializers/devise.rb.
config.navigational_formats = ['*/*', :html, :turbo_stream]

This error is thrown when the after_sign_in_path_for method is redefined in your app and returns nil value. As per my best guest, the provided snippet
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
end
end
is giving an error because none of the conditions are getting satisfied and hence the returned value is nil. To avoid such a case, you can always add an else condition which would get satisfied if no other does. Hence the below snippet should have worked (and will work for other users)
def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
else
some_other_path || root_path
end
end
Hope this helps someone. Cheers :)

In config/devise.rb include this line:
config.navigational_formats = ['/', :html, :turbo_stream]
before rails s
This has done the trick for me.

Answer 4

def after_sign_in_path_for(resource)
if current_user.has_role?(:admin)
dashboard_path
elsif current_user.has_role?(:student)
root_path
else
root_path
end
end
Try to add a else condition in your code. This worked for me. I missed something like this.

Answer 5

If you have the same error with Devise::RegistrationsController, the answers of Jishnu and antoniolulee also works fine.
You have to uncomment in config/initializers/devise.rb line says
config.navigational_formats = ['*/*', :html]
and add :turbo_stream like this
config.navigational_formats = ['*/*', :html, :turbo_stream]

Answer 6

Make sure you've got a method on your AplicationController like follows
def after_sign_in_path_for(resource)
resource.next_step
end
Next_step is an attribute stored in the record during its creation, you may decide to hard code here some other path.
