一个迭代开发中的网站难免存在bug,出bug的时候客户体验就很不好了,为解决此问题,可以在class error产生的时候,触发跳转到统一提示页面,并给开发人员发邮件报错误信息,提高测试能力和用户体验。以下是核心方法;在ApplicationController中添加如下代码,不同rails版本的class error略有变化。
复制代码 代码如下:
AR_ERROR_CLASSES = [ActiveRecord::RecordNotFound, ActiveRecord::StatementInvalid]
ERROR_CLASSES = [NameError, NoMethodError, RuntimeError,
ActionView::TemplateError,
ActiveRecord::StaleObjectError, ActionController::RoutingError,
ActionController::UnknownController, AbstractController::ActionNotFound,
ActionController::MethodNotAllowed, ActionController::InvalidAuthenticityToken]
ACCESS_DENIED_CLASSES = [CanCan::AccessDenied]
if Rails.env.production"No route matches #{params[:unmatched_route]}")
end
def render_ar_error(exception)
case exception
when *AR_ERROR_CLASSES then exception_class = exception.class.to_s
else exception_class = 'Exception'
end
send_error_email(exception, exception_class)
end
def render_error(exception)
case exception
when *ERROR_CLASSES then exception_class = exception.class.to_s
else exception_class = 'Exception'
end
send_error_email(exception, exception_class)
end
def render_access_denied(exception)
case exception
when *ACCESS_DENIED_CLASSES then exception_class = exception.class.to_s
else exception_class = "Exception"
end
send_error_email(exception, exception_class)
end
