强制用户在Devise中注销

Question

我有一个应用程序,用户的会员资格到期.

我正在设置一个before_filter在我的applications.rb文件中,以确保他们的成员资格在让他们进入网站之前是有效的.

在我的application.rb文件中:

before_filter :check_account

def check_account
  if user_signed_in?
     if current_user.account.expired
       flash[:error] = "Your account is expired. Please contact Navanti for renewal."
       redirect_to destroy_user_session_path
     end
  end
end

我不断收到重定向循环错误.我猜这是因为正在调用的注销页面也正在执行before_filter,但如果我把except => [:users => :sign_out]它仍然抛出循环错误.

谢谢您的帮助.

要求的设计方法:

# 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.any(*navigational_formats) { redirect_to redirect_path }
    format.all do
      head :no_content
    end
  end
end

Answer 1

尝试通过以下方式查询控制器/操作:

def check_account
  return if params[:controller] == "devise/sessions" && params[:action] == "destroy"
  if user_signed_in?
     if current_user.account.expired
       flash[:error] = "Your account is expired. Please contact Navanti for renewal."
       redirect_to destroy_user_session_path
     end
  end
end

这应该消除你所拥有的重定向循环.
