我正在努力应对这个设计编程或配置错误。问题是，当我登录我的应用程序时，将我重定向到同一页面而不是主页。此外，如果我输入错误的邮件或错误的密码，则不会出现错误消息。
这是我的routes.rb：
Smarket::Application.routes.draw do
get "home/index"
resources :tipo_transaccions
resources :producto_rematados
resources :provincia_units
resources :propiedadclases
resources :compra_venta_normals
resources :clase_units
resources :prod_of_necs
resources :compra_venta_especials
resources :producto_necesitados
resources :compra_remates
resources :notificacions
resources :comisions
resources :remates
resources :pujas
resources :valors
resources :usuarios
resources :propiedads
resources :regions
resources :productos
resources :estado_remates
resources :ganancia_liquidas
resources :est_prod_of_necs
resources :estado_notificacions
resources :producto_ofertados
resources :comunas
resources :condicions
root :to => "home#index"
devise_for :usuarios, :controllers => { registrations: 'registrations' }, :skip => [:sessions, :registrations]
as :usuario do
get "entrar", to: "devise/sessions#new", :as => :new_usuario_session
post "entrar", to: "devise/sessions#create", :as => :usuario_session
delete "salir", to: "devise/sessions#destroy", :as => :destroy_usuario_session
get "registrarse", to: "devise/registrations#new", :as => :new_usuario_registration
post "registrarse", to: "devise/registrations#create", :as => :usuario_registration
end
end
usuario.rb：
class Usuario < ActiveRecord::Base
mount_uploader :avatar, FotoUploader
include ActiveModel::Validations
# Include default devise modules. Others available are:
# :confirmable, :lockable, :timeoutable and :omniauthable
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
self.table_name = 'usuario'
self.primary_key = 'usuario_id'
validates :usuario_nombre_usuario, :presence => true
validates :usuario_rut, :presence => true
validates :usuario_rut, rut: true
validates :usuario_nombre, :presence => true
validates :usuario_apellidopat, :presence => true
validates :usuario_apellidomat, :presence => true
validates :email, :presence => true
validates :usuario_calle, :presence => true
validates :usuario_numero_calle, :presence => true
validates :usuario_villa, :presence => true
belongs_to :usuario
belongs_to :comuna
和app / views / devise / session / new.html.erb：

答案 0 :(得分：2)
因此，要在sign_in之后重定向到其他页面，您需要覆盖设计方法：
def after_sign_in_path_for resource
home_path
end
对于错误消息，您需要设置以下内容：
<%= form_for(resource, :as => resource_name, :url => session_path(resource_name), :html => { :role => 'form'}) do |f| %>
<%= f.error_messages %>
