ActiveRecord::RecordInvalid - Validation failed: Application must exist with Rails 5 and EmberSimpleAuth

[ghost]

I'm using the github gem in Gemfile of Doorkeeper, Rails and Devise.

I'm using Ember Simple Auth to login Using Resource Owner Password Credentials flow. But when I login with correct username (email) and password I have this error:

Started POST "/oauth/token" for 127.0.0.1 at 2016-01-03 00:10:46 +0100

ActiveRecord::RecordInvalid - Validation failed: Application must exist:

Why I got this?

Which version I have to use?

Everything is pretty default, i'm not using nothing than standard defaults.

[ghost]

Anything?

[tute]

It looks like it needs to know what application are you asking a grant for?

This issue seems very specific to your application rather than with doorkeeper itself. I'd suggest you ask about it in http://stackoverflow.com/questions/tagged/doorkeeper, which will get attention from more people than in this issue tracker. Thank you!

[ghost]

No, I thought this. But not. Using the same configuration default Rails and Doorkeeper Devise and Rails 5 (all from github, with devise and doorkeeper also) and version 4 for the second all works ok, with 5 does not.

[tute]

I don't expect grabbing projects from master to work well together. If you can trigger this for specific versions, and we can replicate it, it is a bug, and we'll work on it. Thanks!

[ghost]

Test yourself with just postman and

grant_type: password
username: userdevise
password: passdevise

Which version I can try with Rails 5.0.0.beta1???

[tute]

Rails 5.0.0.beta1 works indeed with master of doorkeeper, as I didn't yet do a prerelease for doorkeeper 4. What version of devise are you using?

Also, where do I get postman from?

[ghost]

https://www.getpostman.com/

I tried with master of rails, door and devise.

Now i'm trying with rails 5beta, door 3.1.0 and devise master on github...

Devise's latest release is broken with Rails 5.

Now i get this:

Now i'm trying with rails 5beta, door 3.1.0 and devise master on github...

Doorkeeper's latest release is broken with Rails 5, you should use master (form that master I will cut a prerelease, hopefully before I leave for vacations).

[ghost]

Yes, and in fact for this reason I'm using everything on master for write my code. But now doorkeeper break with the error in the first post: "Application must exist".

Can you fix this in master?

What it means "Application must exist"?

[ghost]

Anything?

[tute]

I will need help to reproduce this behavior. Do you have a failing application in GitHub, or concrete steps I can take to get to that error message?

[ghost]

Ok, concrete steps:

Rails 5.0.0.beta1 rails new bla bla bla...

In gemfile:

gem 'doorkeeper', github: 'doorkeeper-gem/doorkeeper'
gem 'devise', github: 'plataformatec/devise'

in initializers/doorkeeper.rb:

...
resource_owner_from_credentials do |routes|
  user = User.find_for_database_authentication(:email => params[:username])
    if user && user.valid_for_authentication? { user.valid_password?(params[:password]) }
      user
    end
  end

...

  grant_flows %w(authorization_code client_credentials password)

...

skip_authorization do |resource_owner, client|
  #   client.superapp? or resource_owner.admin?
    true
  end

I then create a default application for test with name "Test", "urn:ietf:wg:oauth:2.0:oob" and without scopes.

When now I try to receive tokens with Postman (or others client...) I receive this error:

What to do?

If now I modify this file: https://github.com/ginolon/doorkeeper/commit/6d304c8e0aeb04a0ba2f5ced60181f7227e009a9

I receive the token with this params:

grant_type: password
username: userdevise
password: passdevise

[ghost]

Is this a good explanation?

[ashishtajane]

I am also getting the same error with rails 5.0.0.beta1.1 and doorkeeper#master. I was not getting this error couple of days back with rails 4.2.5 and doorkeeper 3.0.1

[ashishtajane]

I think I found why this is happening. This issue (rails/rails#18233) and this PR (rails/rails#18937) makes all belongs_to relations required by default. Thats why absence of application now raises Application must exist validation error. After this change (https://github.com/doorkeeper-gem/doorkeeper/compare/56bfa579484ae9e554028b081227ec8d1b74c21d...ashishtajane:master), I no longer get that validation error.

That's great, thank you both! @ashishtajane, would you like to send a Pull Request with that change, and context from this issue in the commit message? Thank you!

[ashishtajane]

Done. #780

Thank you all! Closing in favor of PR: https://github.com/doorkeeper-gem/doorkeeper/pull/780
