我如何更改标准设计 session_controller，例如，如果我输入了错误的密码，我将被重定向：返回（不是必需的），并查看我的错误...

我需要这个做什么？因为我只在模板中登录，该模板在所有页面的布局左块中呈现，而且我没有新的操作视图...

那么如何通过验证消息错误将错误重定向到其他页面......？

这是标准 session_controller （现在我没有创建它，它是“嵌套的”）：

class Devise::SessionsController < DeviseController
  prepend_before_filter :require_no_authentication, :only => [ :new, :create ]
  prepend_before_filter :allow_params_authentication!, :only => :create
  prepend_before_filter { request.env["devise.skip_timeout"] = true }

  # GET /resource/sign_in
  def new
    self.resource = build_resource(nil, :unsafe => true)
    clean_up_passwords(resource)
    respond_with(resource, serialize_options(resource))
  end

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

  # DELETE /resource/sign_out
  def destroy
    redirect_path = after_sign_out_path_for(resource_name)
    signed_out = (Devise.sign_out_all_scopes ? sign_out : sign_out(resource_name))
    set_flash_message :notice, :signed_out if signed_out && is_navigational_format?

    # We actually need to hardcode this as Rails default responder doesn't
    # support returning empty response on GET request
    respond_to do |format|
      format.all { head :no_content }
      format.any(*navigational_formats) { redirect_to redirect_path }
    end
  end

  protected

  def serialize_options(resource)
    methods = resource_class.authentication_keys.dup
    methods = methods.keys if methods.is_a?(Hash)
    methods << :password if resource.respond_to?(:password)
    { :methods => methods, :only => [:password] }
  end

  def auth_options
    { :scope => resource_name, :recall => "#{controller_path}#new" }
  end
end

也是appcontroller中的方法

def after_sign_in_path_for(resource)      
    case resource
      when User then 
        user = User.find(current_user.id)
        total_markup_for_user = user.groups.map(&:markup).sum
        if current_cart.present?
          cart_id = current_cart.id
        else
          cart_id = nil
        end
        ***
        end
        if request.referrer.to_s.include? "users"
          root_path
        else
          request.referrer 
        end
      when Admin::Admin then :admin_mainpage
    end
  end

Devise 的文档向您展示了如何在此处覆盖其默认重定向：

https://github.com/plataformatec/devise/wiki/How-To:-Redirect-to-a-specific-page-on-successful-sign-in

基本上你会进入你的 application_controller.rb ，例如写这样的东西

def after_sign_in_path_for(resource)
  request.env['omniauth.origin'] || stored_location_for(resource) || new_survey_path
end

def after_sign_out_path_for(resource_or_scope)
 root_path
end

结尾

希望能帮助到你

尝试这样的事情，添加一个新的 respond_with 以防 sign_in 返回 false。

def create
  self.resource = warden.authenticate!(auth_options)
  set_flash_message(:notice, :signed_in) if is_navigational_format?
  if sign_in(resource_name, resource)
    respond_with resource, location: after_sign_in_path_for(resource)
  else
    respond_with resource, location: root_path
  end
end
