How do I login a user with devise?

Question

I have my rails application and I am running into a major issue with devise. I have a controller:

class Users::SessionsController < Devise::SessionsContr         


        

Answer 1

I found this post useful for setting up a login for request specs. https://makandracards.com/makandra/37161-rspec-devise-how-to-sign-in-users-in-request-specs

module DeviseRequestSpecHelpers

  include Warden::Test::Helpers

  def sign_in(resource_or_scope, resource = nil)
    resource ||= resource_or_scope
    scope = Devise::Mapping.find_scope!(resource_or_scope)
    login_as(resource, scope: scope)
  end

  def sign_out(resource_or_scope)
    scope = Devise::Mapping.find_scope!(resource_or_scope)
    logout(scope)
  end

end

Include it in your spec_helper

RSpec.configure do |config|
  config.include DeviseRequestSpecHelpers, type: :request
end

And sign in as needed

sign_in create(:user, name: 'John Doe')

Answer 2

If you want to sign in a user, use the sign_in helper inside your controller's action:

sign_in(:user, user)

Answer 3

Here is how standard create actions works:

  # POST /resource/sign_in
  def create
    self.resource = warden.authenticate!(auth_options)
    set_flash_message!(:notice, :signed_in)
    sign_in(resource_name, resource)
    yield resource if block_given?
    respond_with resource, location: after_sign_in_path_for(resource)
  end

Answer 4

  resource = warden.authenticate!(:scope => resource_name)
   sign_in(resource_name, resource)
