ruby on rails - Allow users to sign in using their username or email address with Devise -

problem

i followed tutorial on devise's wiki page , login page broken. continually error saying 'invalid email or password.' neither user_name nor email work logging in.

note: user name field user_name not username in tutorial.

did miss something? type wrong? part cut , paste.

code

application controller:

## app/controllers/application_controller.rb  class applicationcontroller < actioncontroller::base     protect_from_forgery with: :exception      before_action :configure_permitted_parameters, if: :devise_controller?      protected      def configure_permitted_parameters         devise_parameter_sanitizer.for(:sign_up)              { |u| u.permit( :email, :birthday, :password,:password_confirmation, :remember_me) }         devise_parameter_sanitizer.for(:sign_in)              { |u| u.permit( :login, :user_name, :email, :password, :remember_me ) }         devise_parameter_sanitizer.for(:account_update)              { |u| u.permit( :first_name, :last_name, :user_name, :birthday,                              :address_1, :address_2, :city, :state, :zip_code,                              :facebook, :twitter, :google_plus, :instagram, :pinterest ) }     end  end 

user model:

## app/models/user.rb  class user < activerecord::base     devise  :database_authenticatable, :registerable,             :recoverable, :rememberable, :trackable, :validatable      validates :birthday, :presence => true     validates :user_name, :presence => true, :uniqueness => { :case_sensitive => false }      # virtual attribute authenticating either user_name or email     # in addition real persisted field 'user_name'     attr_accessor :login      def self.find_for_database_authentication(warden_conditions)       conditions = warden_conditions.dup       if login = conditions.delete(:login)         where(conditions.to_h).where(["lower(user_name) = :value or lower(email) = :value", { :value => login.downcase }]).first       else         where(conditions.to_h).first       end     end  end 

devise initializer (uncommented , changed line):

## app/config/initializers/devise.rb  config.authentication_keys = [ :login ] 

login view:

## app/views/devise/sessions/new.html.erb  <% @title="login" %>  <h2>log in</h2>  <%= bootstrap_form_for(resource, as: resource_name, url: session_path(resource_name)) |f| %>    <%= f.alert_message "please fix errors below." %>      <%= f.text_field :login, autofocus: true %>     <%= f.password_field :password %>      <% if devise_mapping.rememberable? -%>       <%= f.check_box :remember_me %>     <% end %>      <%= f.primary "log in" %>  <% end %>  <%= render "devise/shared/links" %> 

devise's error labels (didn't need change have these lines):

## app/config/locales/devise.en.yml  invalid: "invalid %{authentication_keys} or password." ... not_found_in_database: "invalid %{authentication_keys} or password." 

thank in advance can give.

update question

new applicationcontroller code

james milani provided answer in forgot restart server. but, once did that, applicationcontroller code started error providing 2 errors repeated 3 times.

/app/controllers/application_controller.rb:51: syntax error, unexpected '|', expecting '}' { |u| u.permit( :email, :birthda... ^ /app/controllers/application_controller.rb:51: syntax error, unexpected '}', expecting keyword_end 

i changed application controller , errors went away , works:

## app/controllers/application_controller.rb  class applicationcontroller < actioncontroller::base     protect_from_forgery with: :exception      before_action :configure_permitted_parameters, if: :devise_controller?      protected      def configure_permitted_parameters           devise_parameter_sanitizer.for(:sign_up) << :birthday           devise_parameter_sanitizer.for(:sign_in) << :login           devise_parameter_sanitizer.for(:account_update) << :first_name           devise_parameter_sanitizer.for(:account_update) << :last_name           devise_parameter_sanitizer.for(:account_update) << :user_name           devise_parameter_sanitizer.for(:account_update) << :birthday           devise_parameter_sanitizer.for(:account_update) << :address_1           devise_parameter_sanitizer.for(:account_update) << :address_2           devise_parameter_sanitizer.for(:account_update) << :city           devise_parameter_sanitizer.for(:account_update) << :state           devise_parameter_sanitizer.for(:account_update) << :zip_code           devise_parameter_sanitizer.for(:account_update) << :facebook           devise_parameter_sanitizer.for(:account_update) << :twitter           devise_parameter_sanitizer.for(:account_update) << :google_plus           devise_parameter_sanitizer.for(:account_update) << :instagram           devise_parameter_sanitizer.for(:account_update) << :pinterest     end  end 

now, why other code doesn't work, not know, question. of now, question answered. have updated section in case else has same question or issue later.

i made pass through code--looks good; if had 50 or more rep comment, did restart server, right? otherwise initializer won't come effect. maybe that's it?
