5.4 current_user is nil

[nrosella]

I've been following the tutorial fine so far but I'm getting stuck at 5.4

In my user_controllers_spec.rb tests I'm able to set the request headers to the user's auth token that's provided in the factory.

However, by the time I get into the users_controller.rb I find that

User.find_by(auth_token: request.headers['Authorization']) == nil

and hence I don't have a current_user in my update action.

You can find my latest code here should it help: https://github.com/nrosella/market_place_api

Any help would be great!

Thanks

You need a before callback for the authenticate method on the ApplicationController

[nrosella]

I just added before_action :authenticate_user! and now it's breaking lots of tests.

Lots of them with this error:

1) Api::V1::SessionsController POST #create when the credentials are correct returns the user record corresponding to the given credentials
 Failure/Error: @json_response ||= JSON.parse(response.body, symbolize_names: true)

 JSON::ParserError:
   757: unexpected token at 'You need to sign in or sign up before continuing.'`

[kurenn]

Add it just for the update action:

before_action :authenticate_user!, only: [:update]

[nrosella]

Ok back to just the 5 errors now:

[kurenn]

It seems that the controller is not rendering the json object

[nrosella]

Yeah. Been doing a little digging and response.body in users_controller_spec.rb is equal to ""

I found some entries on Stack Overflow that said to include render_views in the test file, but that hasn't done anything for me. Completely stumped on this one...

[kurenn]

How are you rendering the controller json response?

[Orinameh]

My test fails and I get the errors..

1) Api::V1::UsersController PUT/PATCH #update when is not created should respond with 422 Failure/Error: it { should respond_with 422 } Expected response to be a 422, but was 401

./spec/controllers/api/v1/users_controller_spec.rb:101:in `block (4 levels) in <top (required)>'

2) Api::V1::UsersController PUT/PATCH #update when is not created renders the json errors on when the user could not be created Failure/Error: expect(user_response[:errors][:email]).to include "is invalid"

        got: nil

   (compared using eql?)

But once I remove before_action :authenticate_with_token!, only: [:update, :destroy] from the Users Controller, the test passes. What could be the cause?

[kurenn]

Can you share the controller's code along with the tests and routes please?
