Rspec and Devise: Could not find a valid mapping for #<User

Question

using RSpec and Devise, I'm getting a mapping error.

  1) BusinessesController GET index sets @new_vacation
     Failure/Error: sign_in @user
     RuntimeError:
       Could not find a valid mapping for #<User id: 8009, email: "[email protected]", encrypted_password: "$2a$10$joN9Vy6spNAe4uh7W9fcOOdoeSJ5dr/nBwpmlqcv6EYe...", reset_password_token: nil, remember_token: nil, remember_created_at: nil, sign_in_count: 0, current_sign_in_at: nil, last_sign_in_at: nil, current_sign_in_ip: nil, last_sign_in_ip: nil, created_at: "2011-04-01 17:05:03", updated_at: "2011-04-01 17:05:03", business_id: 7214, confirmation_token: nil, confirmed_at: "2011-08-24 21:23:51", confirmation_sent_at: nil, failed_attempts: 0, unlock_token: nil, locked_at: nil, admin: true, password_salt: nil>
     # ./spec/controllers/businesses_controller_spec.rb:10:in `block (2 levels) in <top (required)>'

It looks like the answer might be in here RSpec tests with devise: could not find valid mapping but I can't get it.

Any ideas, I'm really stumped! Thanks.

Answer 1

I had this error in my routes file because I had an API endpoint that I wanted to allow users to reset their passwords from, but I wanted the users to actually do the password change on the web view, which wasn't namespaced under /api

This is how I fixed the routes to make it work:

CoolApp::Application.routes.draw do
  namespace :api, defaults: { format: :json } do
    devise_scope :users do
      post 'users/passwords', to: 'passwords#create'
    end

    resources :users, only: [:create, :update]
  end

  devise_for :users

  root to: 'high_voltage/pages#show', id: 'home'
end

First make sure you have called both 'devise_for' in your routes and 'devise' in your model. I recommend you to read the documentation in the README and in the wiki for more information.

If yes try this:

Put this code into your application.rb

ActionDispatch::Callbacks.after do      
  # Reload the factories
  return unless (Rails.env.development? || Rails.env.test?)

  unless FactoryGirl.factories.blank? # first init will load factories, this should only run on subsequent reloads
    FactoryGirl.factories.clear
    FactoryGirl.find_definitions
  end

end    

This is because Devise uses a mapping between classes and routes, so when a factory built object comes through to Devise after a console reload, or a class redefinition then it will fail. This is commonly the case in development and test environments.

I found it here & worked fine for me- http://blog.thefrontiergroup.com.au/2011/03/reloading-factory-girl-factories-in-the-rails-3-console/

Answer 3

You may want to check your code for multiple devise_for :users declarations in different places. This has been the cause of such an exception in my case, as it surely confused Devise.

Answer 4

I got this in my spec from merely trying to create a model (User.create or factorybot: create(:user)). For me it had something to do with the confirmable devise module.

The fix for me was setting confirmed_at, confirmation_sent_at, etc. on the model (which were sensible defaults for my test) and then the error went away.

FactoryBot.define do
  factory :user do
    sequence(:first_name) { |n| "user_first_name_#{n}" }
    # ...
    confirmed_at { Time.zone.now - 1.hour }
    confirmation_sent_at { Time.zone.now - 1.hour }
    confirmation_token { "abcd1234" }
  end
end

My problem was unrelated to this code. I had recently added a before-filter to always redirect to www.

redirect_to request.protocol + "www." + request.host_with_port + request.fullpath if !/^www/.match(request.host)

I'm still not totally sure why this caused my problem, but it did.
