用户确认后如何重定向到其他页面

Question

我正在使用Rails 3.2.13和Devise 3.2.4。用户注册后，将生成确认链接：

localhost:3000/users/confirmation?confirmation_token=HpPHitLtV3CnLy2z1ZmQ

我想在确认链接上单击后重定向到mentors/new操作，但是在确认后，它重定向到我不需要的/users/sign_in。

到目前为止，这是我的代码：

路线：

devise_for :users
devise_for :users, :controllers => { :confirmations => 'confirmations' }

创建的确认控制器，并从Devise :: ConfirmationsController重写：

class ConfirmationsController < Devise::ConfirmationsController
  protected

def after_confirmation_path_for(resource_name, resource)
  if resource.has_role? :user
    redirect_to new_mentor_path("account_id")
  else
    root_path
  end
end
end

在ConfirmationsController中，也许我必须添加一些额外的代码。

在应用程序控制器中，我有以下代码，成功登录后，我将其带到mentor/student家：

def after_sign_in_path_for(resource_or_scope)
if resource_or_scope.is_a?(User)
  if current_user.user_type == "mentor"
    home_mentors_path(:account_id => current_user.account_id)
  else
    home_students_path(:account_id => current_user.account_id)
  end
end

结束

def after_sign_up_path_for(resource_or_scope)
  root_path
end

通常，逻辑是这样的，但是我不明白如何用Devise做到这一点：

def activate
  @user = User.where("activation_code = ?","#{params[:id]}").first
  if [email protected]?
   if @user.created_at < 24.hours.ago
     if @user and @user.activate
      cookies[:user_id][email protected]
      if @user.user_type == "student"
        redirect_to new_student_path
      else
        redirect_to new_mentor_path
      end
    else
      @user.destroy
      redirect_to "/"
    end
  else
    @user.destroy
    redirect_to "/"
  end
else
  redirect_to "/"
end

结束

Answer 1

# GET /resource/confirmation?confirmation_token=abcdef
def show
  self.resource = resource_class.confirm_by_token(params[:confirmation_token])
  yield resource if block_given?

  if resource.errors.empty?
    set_flash_message(:notice, :confirmed) if is_flashing_format?
    respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
  else
    respond_with_navigational(resource.errors, status: :unprocessable_entity){ render :new }
  end
end

现在您已覆盖Devise的after_confirmation_path方法：

protected
def after_confirmation_path_for(resource_name, resource)
  if resource.has_role? :user
    redirect_to new_mentor_path("account_id")
  else
    root_path
  end
end

这很好，Devise将重定向到您的new_mentor_path，但在Mentor控制器内部，您将有一个before文件管理器来检查身份验证，例如：

before_action :authenticate_user! #this will check if your user is signed in or not and if not it'll redirect you

因此，如@Rich Peck所建议，您基本上还需要覆盖show操作，以便您的用户在重定向到您的new_mentor_path之前已登录。

在show操作中，您可以执行以下操作来确保您的用户已登录：
# GET /resource/confirmation?confirmation_token=abcdef
def show
  self.resource = resource_class.confirm_by_token(params[:confirmation_token])

  if resource.errors.empty?
    set_flash_message(:notice, :confirmed) if is_navigational_format?
    sign_in(resource)
    respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
  else
    respond_with_navigational(resource.errors, :status => :unprocessable_entity){ render :new }
  end
end

此外，我在您的after_confirmation_path中注意到您有

redirect_to new_mentor_path("account_id")

您为什么在路径中将account_id作为字符串传递？

如果您的account_id是整数，则必须先在show操作中设置它，然后像[]那样调用after_confirmation_path
respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource, account_id) }

此外，您还必须更改after_confirmation_path的定义，例如：

def after_confirmation_path_for(resource_name, resource, account_id)
  if resource.has_role? :user
    redirect_to new_mentor_path(account_id)
  else
    root_path
  end
end 

Answer 2

class ConfirmationsController < Devise::ConfirmationsController
  def show
  self.resource = resource_class.confirm_by_token(params[:confirmation_token])

if resource.errors.empty?
  set_flash_message(:notice, :confirmed) if is_navigational_format?
  sign_in(resource)  #This will detect if user is logged in.

  respond_with_navigational(resource){ redirect_to after_confirmation_path_for(resource_name, resource) }
else
  respond_with_navigational(resource.errors, :status => :unprocessable_entity){ render :new }
 end
end

protected
def after_confirmation_path_for(resource_name, resource)

  if resource.is_a?(User)
   new_mentor_path("account_id") #do not provide redirect_to which is already taken in respond_with_navigational(resource)
  else
   root_path
  end
 end  
end

我注释了devise_for :users，因为每次单击确认链接时都会调用此路由，并且不会调用确认控制器并重定向到登录路径。这是我面临的问题的主要解决方案：

# devise_for :users
devise_for :users, :controllers => { :confirmations => 'confirmations' }
