除非登录信息不正确,否则/devise/session/new.html.erb将被渲染.
我不想要我希望我的用户被重定向到root_url与闪存消息中的错误.
我能够覆盖registrations_controller.rb的另一个功能,但覆盖sessions_controller.rb给了我很多麻烦.
我想换什么来做我想要的？我仍然希望将用户重定向到after_sign_in_path,如果登录正确.
原控制器为here
到目前为止,我知道我必须在我的路线
devise_for：users,：controllers => {：registrations => “注册”,：sessions => “会议”}
而且我还设置了controller / sessions_controller.rb
class SessionsController < Devise::SessionsController
# GET /resource/sign_in
def new
resource = build_resource
clean_up_passwords(resource)
respond_with_navigational(resource,stub_options(resource)){ render_with_scope :new }
end
end
我有这样的感觉,我必须改变render_with_scope：新的但…如何？
使用该版本,我得到#< SessionsController：0x5072c88>的错误undefined方法’users_url’
嗯,我会等待你的宝贵帮助
PS：post帮助我很多处理订阅错误.也许这将有助于登录错误？
====编辑====
遵循第一个回答建议,我还添加了初始化器/ devise.rb：
config.warden do |manager| manager.failure_app = CustomFailure end
当用户未登录并尝试访问“受限制”区域时,他会被重定向到root_url,但是当登录错误时,我现在有以下错误：
The action 'devise/sessions#new' could not be found for Devise::SessionsController
(PS：我删除了我使用会话控制器所做的一切,如果成功则登录工作)

<% flash.each do |name,msg| %>
<% if msg.class == Array %>
<% msg.each do |message| %>
<%= content_tag :p,message,:id => "flash_#{name}" %>
<% end %>
<% else %>
<%= content_tag :p,msg,:id => "flash_#{name}" %>
<% end %>
<% end %>
=== FINAL UPDATE ===
接受的答案有效.只是不要忘记显示闪光警报
解决方法
在lib / custom_failure.rb下添加此自定义失败类
class CustomFailure < Devise::FailureApp
def respond
if http_auth?
http_auth
elsif warden_options[:recall]
recall
else
redirect
end
end
def redirect
store_location!
flash[:alert] = i18n_message unless flash[:notice]
redirect_to "/"
end
def recall
env["PATH_INFO"] = attempted_path
flash.now[:alert] = i18n_message(:invalid)
self.response = recall_controller.action(warden_options[:recall]).call(env)
end
protected
def i18n_message(default = nil)
message = warden.message || warden_options[:message] || default || :unauthenticated
if message.is_a?(Symbol)
I18n.t(:"#{scope}.#{message}",:resource_name => scope,:scope => "devise.failure",:default => [message,message.to_s])
else
message.to_s
end
end
def warden_options
env['warden.options']
end
def warden
env['warden']
end
def recall_controller
"#{params[:controller].camelize}Controller".constantize
end
def attempted_path
warden_options[:attempted_path]
end
def store_location!
session[:"#{scope}_return_to"] = attempted_path if request.get? && !http_auth?
end
def attempted_path
warden_options[:attempted_path]
end
def http_auth?
!Devise.navigational_formats.include?(request_format) || (request.xhr? && Devise.http_authenticatable_on_xhr)
end
end
在config / application.rb下写下
config.autoload_paths += %W(#{config.root}/lib)
_________________编辑__________________
你说当“注册出错”时,这意味着控件应该在registrations_controller创建方法中.我猜,那里的东西一定是错的.尝试添加这些路由.
devise_for :users
devise_scope :user do
root :to => "devise/sessions#new"
get "sign_in",:to => "devise/sessions#new"
get "sign_out",:to => "devise/sessions#destroy"
get "sign_up",:to => "devise/registrations#new"
end
________________编辑2 ________________
在视图/ devise / registrations / new.html.erb中添加
<%= devise_error_messages! %>
