devise配置登录超时和单处登陆
1.配置用户超时
<Project>/config/initializers/devise.rb
编辑 # config.timeout_in = 30.minutes 这一行，修改为想要配置的时间
<Project>/app/models/user.rb
配置devise :database_authenticatable, :registerable,这一行，加上 :timeoutable
2.设置用户单处登陆
原理：devise在用户登陆后会设置users表中的current_sign_in_at字段为最后一次登陆的时间，用户每次登陆后在session中保存current_sign_in_at字段，在application中校验session中current_sign_in_at字段，如果为空或者小于current_user对象的current_sign_in_at则强制注销
1) 在application_controller基类中定义after_sign_in_path_for方法在当中设置session对象
def after_sign_in_path_for(resource)
session[:current_sign_in_at] = current_user.current_sign_in_at
root_path
end
2) 定义has_signed取代:authenticate_user!判断用户登陆
def has_signed
unless user_signed_in?
redirect_to root_path
else
if session[:current_sign_in_at] == nil or session[:current_sign_in_at] < current_user.current_sign_in_at
redirect_to destroy_user_session_path
end
end
end
3)在需要判断用户登陆的controller中添加before_action :has_signed过滤器。
