NoMethodError (undefined method `name' for nil:NilClass) - devise_controller.rb:22

[rmagnum2002]

Scenario - I log in successfully, and navigate through pages as a logged in user until I hit refresh.
Happens with this line:

# config.change_headers_on_each_request = true

commented, uncommented, set to true or false.. all cases.

NoMethodError (undefined method `name' for nil:NilClass):
  devise (3.4.1) app/controllers/devise_controller.rb:22:in `resource_name'
  devise_token_auth (0.1.31) app/controllers/devise_token_auth/application_controller.rb:10:in `resource_class'
  devise_token_auth (0.1.31) app/controllers/devise_token_auth/concerns/set_user_by_token.rb:19:in `set_user_by_token'

line 22 from devise_controller:

21  def resource_name
22    devise_mapping.name
23  end

What do the request and response headers look like? This can be found in the "network" tab of your web inspector.

[rmagnum2002]

@lynndylanhurley the response tab was a bunch of html code that looked like usual rails exception errors, so I am not sure this is what you need, however, I'll post the info I have step by step:

1. Headers when I sign in successfully:

https://gist.github.com/rmagnum2002/8f86bcfb84d3f64ce2cc

1. Console logs when I sign in successfully:

https://gist.github.com/rmagnum2002/93be6c4ab7ca20f66104

Nothing to show when I navigate through pages, it's all angular and I have the sign out link in the menu, so I assume sign in works as expected.

1. Headers when I refresh the page (error comes when app does a request to /api/auth#validate_token)
   https://gist.github.com/rmagnum2002/58508565bb7147acffbf
   and
2. console logs for step 3

I had this same problem when mounting under a namespace (/api/v1 in my case). The problem disappeared after moving the devise mounting out of the namespace.

Hi,
I had the same issue as mentioned, and it actually works if the routes are places outside the namespace. You could keep the namespace effect by mounting it to "/api/auth" instead of just "/auth"

+1. @aihaddad's solution works, but that hardly sounds like the way it should be.

[xanthfan]

I'm getting this problem as well. Moving the devise mounting out of the namespace, gets me past the "undefined method `name' for nil:NilClass" error. But the validate request is stopped at a different error:

"ArgumentError (wrong number of arguments (2 for 1)):"

Gist with my routes.rb file :
https://gist.github.com/anonymous/c70726923548716fc236

Gist with the console output:
https://gist.github.com/anonymous/0d27838fc166796cd4ca

I've been trying to get ng_token_auth and devise_token_auth to work all week. Love the work you're doing, please help!

[xanthfan]

Also here are my versions:

devise_token_auth (0.1.32)
  devise (~> 3.3)
  rails (~> 4.2)

[aihaddad]

I think you need to revise your route to "/auth" instead of "auth"

[xanthfan]

As it turned out, my bug was not the fault of devise_token_auth. Other git branches of my app (which use the original devise gem) were giving me the same "wrong number of arguments" error. So the problem was with a dependent gem somewhere. Clearing gems and re-bundling solved the problem.

[dkoloditch]

I experienced the same issue in regard to the /api/v1/ namespace. I moved the mount line from within the namespace in routes...:

namespace :api do
    namespace :v1 do
      mount_devise_token_auth_for 'User', at: 'auth'
      ...
    end
end

...to outside of the namespace while referencing the correct path:

mount_devise_token_auth_for 'User', at: 'api/v1/auth'

namespace :api do
    namespace :v1 do
      ...
    end
end

[ksinghal]

when I move it out of the namespace as @dkoloditch suggested, the before_filter authenticate_user! conflicts with that of devise. Is there any other way to resolve this issue?

[toshimaru]

@dkoloditch thaanks for the solution. It works.

[Salet]

I'm experiencing exact same problems @xanthfan had. When devise_token is mounted under a namespace, I get logged out after page refresh, and when it's outside I hit:

ArgumentError (wrong number of arguments (2 for 1)):
devise (3.5.2) lib/devise.rb:454:in `[]'

However, my Gemfile is almost empty and I continue failing on making this work. Any help appreciated.

[duleorlovic]

+1 for @dkoloditch solution

[Salet]

Solution provided by @dkoloditch works. If you however encounter following error:

ArgumentError (wrong number of arguments (2 for 1)):
devise (3.5.2) lib/devise.rb:454:in `[]'

like I and @xanthfan did, clear up your cookies. I had cookies set up by other application using older devise which were causing this.

The namespaced auth route issue is also discussed in #219
